All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning.
This driver uses semantic versioning:
Changed all uses of Record<string, unknown> to Record<string, any> (#750)
This should allow using more specific types without having to implement index signatures.
Added collection.documents for fetching multiple documents
Added support for fillBlockCache query option
Added support for passing Graph objects in AQL queries (#740)
This also adds the isArangoGraph helper function for type checking.
Added User Management API (#664)
This implements the endpoints of the HTTP Interface for User Management
Added missing hex flag to StopwordsAnalyzer type (#732)
Added missing details flag to collection.figures (#728)
Added missing inBackground flag to index options (#734)
Added support for new ArangoDB 3.8 Analyzer types
This adds the PipelineAnalyzer, AqlAnalyzer, GeoJsonAnalyzer,
GeoPointAnalyzer and StopwordsAnalyzer types in TypeScript, as well as
the Analyzer-specific properties types.
Added support for new ArangoDB 3.8 estimates option for indexes
This affects the PersistentIndex, HashIndex and SkiplistIndex types
in TypeScript.
Implemented toJSON methods for ArangoError and HttpError (#632)
This prevents an error where JSON.stringify would reliably throw if passed
an instance of either of these error types generated by arangojs. Note that
you may still want to implement your own JSON representation logic as system
errors (e.g. ECONNREFUSED) are not wrapped by arangojs and thrown as-is.
Stack traces are now improved for most errors when using precaptureStackTraces (#722)
Previously this option would only affect network errors, making it far less
useful than intended. Now parsing errors, ArangoError instances and HTTP
errors also receive improved error stack traces when this option is enabled.
Improved performance for precaptureStackTraces when no errors occur
The generated stack is now only accessed on demand, allowing the runtime to delay generation of the stack trace string. Previously the stack would always be accessed prior to the request being sent, causing a noticeable delay even when no error occurs.
Fixed document selector validation in collection.edges and its variants (#704)
These methods previously only permitted start vertices that are documents within the edge collection itself. This behavior has now been corrected to permit start vertices outside the collection, as expected.
Changed the default for agentOptions.scheduling to "lifo"
This is already the default in Node v15.6 but can reduce latency caused by sockets expiring, especially with larger connection pools and infrequent requests.
Removed keepAlive-specific throughput optimization
Previously arangojs would allow agentOptions.maxSockets * 2 concurrent
requests, to optimize socket reuse by avoiding idle time. This behavior
could trigger deadlocks when attempting to perform multiple transactions
in parallel and only marginally improved throughput in some high-load
scenarios. The connection pool size now always reflects the value set in
agentOptions.maxSockets regardless of whether keepAlive is enabled.
Changed agentOptions.maxSockets default value when using ROUND_ROBIN
As the connection pool is shared across all server connections when using
ROUND_ROBIN load balancing, the default value of 3 is too limiting for
most scenarios involving multiple coordinators. When passing multiple URLs
via the url option and specifying ROUND_ROBIN load balancing, arangojs
will now default this value to url.length * 3 instead.
Added db.waitForPropagation method
This method helps with setting up databases in a cluster scenario by waiting for a request to succeed on every known coordinator.
This is a maintenance release and contains no bugfixes or features.
Fixed incorrect HTTP method call in patch method (#687)
Fixed empty query results containing [undefined] (#683)
Fixed updateByExample and replaceByExample new value parameter name
Note that these methods are still deprecated. Previously the newValue
parameter was incorrectly called newData, which prevented the methods from
working at all.
This is a maintenance release because the initial v7 release did not include a README file.
This is a major release and breaks backwards compatibility.
See the migration guide for detailed instructions for upgrading your code to arangojs v7.
For a detailed list of changes between pre-release versions of v7 see the Changelog of the final v7 release candidate.
Removed ArangoDB 2.8 support
ArangoDB 2.8 has reached End of Life since mid 2018. Version 7 and above of arangojs will no longer support ArangoDB 2.8 and earlier.
Removed Node.js 6/8 support
As of version 7 arangojs now requires language support for async/await. This means arangojs requires Node.js 10 (LTS) or newer to function correctly.
Removed support for absolute endpoint URLs
This removes the isAbsolute option from the arangojs configuration.
Removed ArangoError re-export
The type can still be imported directly from the error module.
Removed statusCode properties of ArangoError and HttpError
Both of these error types still expose the HTTP status code as the code
property. For ArangoError the true HTTP status code may be different and
can still be accessed using the response.statusCode property.
Removed db.edgeCollection method
As arangojs 7 uses the same implementation for document and edge collections,
this method is no longer necessary. Generic collection objects can still be
cast to DocumentCollection or EdgeCollection types in TypeScript.
Removed db.truncate convenience method
This was a wrapper around db.listCollections and collection.truncate.
The behavior of db.truncate can still be emulated by calling these methods
directly.
Removed collection createCapConstraint, createHashIndex,
createSkipList, createPersistentIndex, createGeoIndex and
createFulltextIndex methods
These methods are no longer part of the official ArangoDB API and can be
replaced by using the collection.ensureIndex method.
Removed save(fromId, toId, edgeData) method variants
Methods for creating edges now require the _to and _from attributes to
be specified in the edge (document) data and no longer accept these values
as positional arguments.
Removed collection.bulkUpdate method
The new method collection.updateAll now provides this functionality.
Removed collection.edge method
This method was previously an alias for collection.document.
The method graphEdgeCollection.edge is unaffected by this change.
Removed graphName option for edgeCollection.traversal
Graph traversals can still be performed via graph.traversal.
Removed generic collection methods from GraphVertexCollection
All methods that are not part of the graph API have been removed.
The underlying collection can still be accessed from the collection
property.
Removed generic collection methods from GraphEdgeCollection
All methods that are not part of the graph API have been removed.
The underlying collection can still be accessed from the collection
property.
Removed cursor.some and cursor.every methods
These methods encouraged overfetching and should be replaced with more efficient AQL queries.
The behavior can still be implemented by using the next method directly
or iterating over the cursor using the forEach method or the for await
syntax.
Removed ViewResponse type
The type ViewDescription represents the same structure.
Removed ArangoSearchViewPropertiesResponse type
The type ArangoSearchViewProperties & ViewDescription can be used
to represent the same structure.
Deprecated db.useDatabase method
Using this method will affect Collection, Graph and other objects
already created for the given database and change which database these
refer to, which may cause unexpected behavior.
As of arangojs 7 the db.database method can be used instead to create a
new, separate Database object using the same connection pool.
Deprecated Collection methods for simple queries: list, all, any,
byExample, firstExample, removeByExample, replaceByExample,
updateByExample, lookupByKeys, removeByKeys, fulltext
These methods were deprecated in ArangoDB 3.4 and should no longer be used. They will still behave correctly with versions of ArangoDB supporting these methods but may be removed in a future ArangoDB release.
Their behavior can be emulated using AQL queries.
Deprecated graph.traversal and collection.traversal
These methods were deprecated in ArangoDB 3.4 and should no longer be used. They will still behave correctly with versions of ArangoDB supporting these methods but may be removed in a future ArangoDB release.
Their behavior can be emulated using AQL graph traversal.
Multiple Database objects can now share a single Connection
All arangojs objects now reference a Database object rather than accessing
the underlying Connection directly. This allows multiple Database objects
to be created by using the db.database method while still allowing the
creation of separate database objects with separate connection pools if
desired.
Memoized Database, Collection, Graph, View and Analyzer
Database objects are now memoized per-connection and the other object types
are memoized per-database. Using useDatabase de-memoizes the database
object to prevent unexpected behavior.
Added support for View in aql templates (#667)
View (or ArangoSearchView) objects can now be passed into aql templates
like ArangoCollection objects.
Moved collectionToString helper into collection module
Moved Dict type into connection module
Moved Patch type into documents module
Removed Errback type from public API
Renamed util/foxx-manifest module to foxx-manifest
Renamed method db.arangoSearchView to db.view
Renamed method db.createArangoSearchView to db.createView
Replaced methods db.enableServiceDevelopmentMode and
db.disableServiceDevelopmentMode with db.setServiceDevelopmentMode
Flattened database query method options argument
The optional options argument previously contained an additional options
object with additional query options. These options are now specified on the
options argument itself directly.
Before:
db.query(aql`FOR doc IN ${collection} RETURN doc`, {
cache: false,
options: { fullCount: true },
});
After:
db.query(aql`FOR doc IN ${collection} RETURN doc`, {
cache: false,
fullCount: true,
});
Changed db.listServices option excludeSystem default to true
To be more consistent with the equivalent options in other methods,
the default value has been changed from false to true.
Changed db.createDatabase return type to Database
Renamed database.setQueryTracking to database.queryTracking
The method will now return the existing query tracking properties or set the new query tracking properties depending on whether an argument is provided.
Method db.transaction no longer acts as an alias for executeTransaction
The method now only allows looking up transactions by ID. Previously it would
wrap executeTransaction if passed the arguments expected by that method.
Merged DocumentCollection and EdgeCollection APIs
All collections are now implemented as generic Collection objects.
In TypeScript the generic collection object can still be explicitly cast to
DocumentCollection or EdgeCollection for stricter type safety.
Renamed collection.setProperties to collection.properties
The method will now return the existing properties or set the properties depending on whether an argument is provided.
Removed CollectionMetadata fields from CollectionProperties type
Methods that previously returned CollectionProperties now return
CollectionMetadata & CollectionProperties.
Collection methods save, update, replace and remove no longer take
arrays as input
The array versions have been renamed to saveAll, updateAll, replaceAll
and removeAll to reduce the likelihood of mistakes and provide more helpful
type signatures.
Collection methods will now throw errors when passed documents or document IDs from different collections where a document key or ID for a document in the same collection is expected
For example the following code will now result in an error rather than the document from a different collection being returned:
const aliceId = "alice/123"; // Document from collection "alice"
const bobCol = db.collection("bob"); // Collection "bob"
const doc = await bobCol.document(aliceId); // THROWS
Changed collection.import option type behavior
Previously this option would always default to "auto".
When passing a string, Buffer or Blob as data, the option now defaults
to undefined. This matches the behavior in previous versions of setting
the option explicitly to null.
Additionally, the value "array" has been replaced with "list".
When passing an array as data, the option is now no longer supported as the corresponding value will be inferred from the array’s contents:
If the array’s first item is also an array, it will match the behavior in
previous versions of setting the option explicitly to null.
Otherwise it will match the behavior in previous versions of setting the
option explicitly to "documents" or "auto", or omitting it entirely.
Changed collection.list return type to ArrayCursor
Graph methods now also accept ArangoCollection instances instead of names
This brings these methods behavior in line with that of the beginTransaction
and executeTransaction methods of Database objects.
Graph create method (and db.createGraph) signature changed
The graph.create method now takes an array of edge definitions as the
first argument and any additional options (not just the waitForSync
option) as the second argument.
Before:
await graph.create(
{
edgeDefinitions: [{ collection: "edges", from: ["a"], to: ["b"] }],
isSmart: true,
},
{ waitForSync: true }
);
After:
await graph.create([{ collection: "edges", from: ["a"], to: ["b"] }], {
isSmart: true,
waitForSync: true,
});
First argument to graph.replaceEdgeDefinition is now optional
Since the new edge definition already includes the edge collection name that identifies the edge definition, it is now possible to specify only the new edge definition object without additionally specifying the collection name as the first argument.
Before:
await graph.replaceEdgeDefinition("edges", {
collection: "edges", // This is a bit redundant
from: ["a"],
to: ["b"],
});
After:
await graph.replaceEdgeDefinition({
collection: "edges",
from: ["a"],
to: ["b"],
});
Graph collection return values now contain old and new properties when
returnOld or returnNew options are used
This behavior represents a compromise between remaining consistent with the behavior of the regular collection method equivalents and remaining compatible with the ArangoDB HTTP API response object quirks.
Replaced ArrayCursor methods hasNext and hasMore with getters
Renamed ArrayCursor method each to forEach
Renamed cursor.nextBatch to cursor.batches.next
Renamed cursor.hasMore to cursor.batches.hasMore
In TypeScript ArrayCursor is now a generic type
TypeScript users can now cast cursor instances to use a specific type for
its values rather than any to aid type safety.
Renamed view.setProperties to view.updateProperties
Renamed type ArangoView to View
ArangoAnalyzer to AnalyzerRenamed type ArangoTransaction to Transaction
Renamed transaction.run to transaction.step
This should hopefully make it more obvious that sequential calls to arangojs methods should be split into separate calls of this method.
Added databaseName configuration option
Setting this option to a database name will result in the initial Database
object using this database instead of the default _system database.
Added auth configuration option
It is now possible to pass authentication credentials using the auth
option in addition to calling db.useBasicAuth or db.useBearerAuth.
Added precaptureStackTraces configuration option (#599)
This option can be used to get more useful stack traces but results in a performance hit on every request.
Added before and after to the agentOptions configuration option (#585)
These methods can be used to track performance metrics for outgoing requests.
Improved type signatures for TypeScript and inline documentation
Most methods should now provide full type signatures for options and response objects and provide inline documentation in IDEs and editors that support this feature in TypeScript and JavaScript.
Added db.database method
This method replaces the use case for the deprecated db.useDatabase
method.
Added support for extended options in db.createDatabase
This method now supports passing an extended options object instead of passing the users array directly.
Added db.createCollection and db.createEdgeCollection methods
These are convenience methods wrapping collection.create. In TypeScript
createEdgeCollection will return a collection cast to the EdgeCollection
type.
Added db.createGraph method
This is a convenience method wrapping graph.create.
Added db.createArangoSearchView method
This is a convenience method wrapping view.create.
Added db.createAnalyzer method
This is a convenience method wrapping analyzer.create.
Added support for db.createFunction option isDeterministic
Added support for db.listServices option excludeSystem
Added collection saveAll, updateAll, replaceAll and removeAll methods
These methods replace the respective array versions of the collection
methods save, update, replace and remove, which no longer accept
arrays as inputs.
Added collection.documentId method
The method takes a document or a document key and returns a fully qualified document ID string for the document in the current collection.
Added support for values "ignore" and "conflict" in overwriteMode
option when saving documents using the Collection API
Added graphVertexCollection.vertexExists and
graphEdgeCollection.edgeExists methods
These mimic the behavior of the collection.documentExists method but using
the Graph API.
Added graphVertexCollection.collection and graphEdgeCollection.collection
These properties now provide access to regular (non-graph) collection objects for these graph collections. These objects can be used to perform operations not available within the context of a graph (e.g. bulk imports or modifying the collection itself).
Added support for isDisjoint option in Graph API
Added cursor.flatMap method
This method behaves similarly to the Array method flatMap but operates
on the cursor directly like cursor.map does.
Added cursor.batches to provide a batch-wise cursor API
Added support for for await in ArrayCursor (#616)
It is now possible to use for await to iterate over each item in a cursor
asynchronously.
primarySortCompression and storedValues options in
View APIRemoved TypeScript dependency on dom library
If you are using arangojs in Node.js, you no longer need to add the dom
library to your tsconfig.json configuration.
Fixed db.dropFunction option group being ignored
Fixed documentation of db.runServiceTests
Previously the documentation incorrectly indicated that the default value
of the idiomatic option is true. The correct default value is false.
Added uuid and padded to legal KeyGeneratorType values in TypeScript (#656)
Added overwrite to InsertOptions type in TypeScript (#657)
db.listTransactions and db.transactions methodsEmpty querystring parameters are now omitted
In some cases ArangoDB would be unable to correctly handle querystring
parameters without values. Any paremeters set to undefined will now
no longer be added to the querystring.
This does not affect parameters set to empty string values.
maxRuntime option to db.query methodReplaced linkedlist dependency with x3-linkedlist (#601)
The linkedlist dependency had a memory leak and was no longer maintained.
The replacement should fix this issue.
Added cursor.kill method
Cursors that have not yet been fully depleted can now be killed using the
cursor.kill method. Note that this method has no effect if the cursor
is already depleted.
Added cursor.nextBatch method
Cursors normally fetch additional batches as necessary while iterating over the individual results, this method allows consuming an entire batch at a time.
Fixed View properties not being passed correctly when creating Views (#621)
Renamed internal response.host attribute to response.arangojsHostId (#604)
In some environments the host attribute is already present and read-only.
This should avoid a TypeError being thrown when a value is assigned by
arangojs.
Renamed db.transaction to db.executeTransaction
The method for executing server-side transactions is now called
executeTransaction and the params argument now must be passed via the
options object.
For backwards-compatibility the new db.transaction method will continue to
behave like before when passed an action string as the second argument.
Note that this behavior is deprecated and will be removed in arangojs 7.
Added support for ArangoDB 3.5 streaming transactions
New streaming transactions can be created using db.beginTransaction and
existing streaming transactions can be accessed by passing the transaction ID
to db.transaction.
See the documentation of the transaction.run method for examples of using
streaming transactions with arangojs.
Added support for ArangoDB 3.5 Analyzers API
See the documentation of the database.analyzer method and the Analyzer
instances for information on using this API.
Added collection.getResponsibleShard method
Added support for new ArangoDB 3.5 collection properties
Added support for new ArangoDB 3.5 View properties
Fixed a problem causing empty nested AQL expressions to be converted to bind variables
Nesting an empty AQL expression like the result of calling aql.join with an empty
array would previously result in the AQL expression not being recognized and being
converted to an object bind variable instead.
Changed Views API to match 3.4 GA implementation
This release updates the Views API to the version implemented in the final ArangoDB 3.4 GA release. Please note that these changes may break code written for earlier ArangoDB 3.4 release candidates.
Added timeout option to db.query and request methods (#572)
Note that this merely cancels the request. Queries will still be executed and ArangoDB will still continue processing the request, this will merely result in the socket being forcefully disconnected.
Added query management API (#474)
This implements most endpoints of the HTTP Interface for AQL Queries.
Restored support for credentials in URLs
If the server URL includes credentials, arangojs will now use them instead of
the default username “root” and an empty password. Any credentials explicitly
set using useBasicAuth or useBearerAuth will still override the default
credentials as before.
Added any[] to allowed types for AQL bind parameters
This should help in some cases where the previous TypeScript annotation was too restrictive.
Added support for UNIX socket URLs (#405)
In addition to the unix:///socket/path and http+unix:///socket/path
URL formats recognized by ArangoDB, arangojs also supports the format
http://unix:/socket/path commonly supported in the Node ecosystem and
automatically converts ArangoDB endpoint URLs between them.
No longer emitting undefined values in aql template strings
Previously using undefined values in an aql template string would result
in a bind parameter being added with no value, which would always lead to an
error response when ArangoDB executes the query.
Now undefined values will simply be omitted, also easing the conditional
insertion of query fragments.
Changed experimental Views API
This release updates the experimental support for the Views API to the version implemented in the ArangoDB 3.4 release candidate. Please note that this API is still subject to change and may indeed still change until the 3.4.0 GA release.
Updated TypeScript to version 3
This may result in type signatures that are incompatible with TypeScript 2 being added in future releases (including patch releases).
Added nesting support for aql template strings (#481)
It is now possible to use aql queries as values in aql template strings:
function createQuery(flowers, color) {
const filter = color ? aql`FILTER flower.color == ${color}` : undefined;
return aql`FOR flower IN ${flowers} ${filter} RETURN flower`;
}
createQuery(db.collection("flowers", "green"));
// FOR flower IN @@value0 FILTER @value1 RETURN flower
// {"@value0": "flowers", "value1": "green"}
createQuery(db.collection("flowers"));
// FOR flower IN @@value0 RETURN flower
// {"@value0": "flowers"}
Previously aql fragments could only be created with aql.literal, which
does not support bind parameters:
aql.literal("FILTER flower.color == " + JSON.stringify(color));
// Note that we had to rely on JSON.stringify to correctly escape the value
// because the value is part of the literal, not a bind parameter
Added support for undefined and AQL literals to aql.literal
Passing undefined to aql.literal will now result in an empty literal as
would be expected. Passing an AQL literal back into aql.literal will return
the existing literal rather than the string [object Object].
Added aql.join function
The function aql.join can be used to convert an array of aql queries into
a combined query:
const users = db.collection("users");
const keys = ["a", "b", "c"];
const fragments = keys.map((key) => aql`DOCUMENT(${users}, ${key})`);
const combined = aql`[${aql.join(fragments, ", ")}]`;
// [DOCUMENT(@@value0, @value1), DOCUMENT(@@value0, @value2), \
// DOCUMENT(@@value0, @value3)]
// {"@value0": "users", "value1": "a", "value2": "b", "value3": "c"}
const query = aql`FOR user IN ${combined} RETURN user.email`;
// FOR user IN [DOCUMENT(@@value0, @value1), DOCUMENT(@@value0, @value2), \
// DOCUMENT(@@value0, @value3)] RETURN user.email
// {"@value0": "users", "value1": "a", "value2": "b", "value3": "c"}
Added allowDirtyRead option to db.query and collection.document
Dirty reads are supported in leader/follower replication setups and require ArangoDB 3.4 or later. When performing a request that permits dirty reads, arangojs will load balance across all know leaders and followers and instruct ArangoDB to allow responding with stale or dirty response data. Note that data returned from a dirty read may be out of date or inconsistent.
Re-implemented collection.import
The previous implementation was broken. The new implementation should be backwards-compatible in cases where it previously wasn’t broken but is more flexible and also handles buffers.
Added missing dependency on @types/node (#567)
This should solve TypeScript errors when the dependency was not already added.
Fixed edgeCollection.save not respecting options (#554)
Fixed database.createDatabase TypeScript signature (#561)
Requests that fail because a server can not be reached are now automatically retried if other servers are available
This behavior can be controlled using the maxRetries option.
Renamed EdgeCollection#edge to EdgeCollection#document
EdgeCollection#edge is now an alias for the document method.
Renamed GraphEdgeCollection#edge to GraphEdgeCollection#document
GraphEdgeCollection#edge is now an alias for the document method.
Renamed GraphVertexCollection#vertex to GraphVertexCollection#document
GraphVertexCollection#vertex is now an alias for the document method.
Added maxRetries option to configuration to control retry behavior
Added collection.documentExists method
Added graceful option to collection.document
opts in DocumentCollection#saveAdded ArangoError and CollectionType to public exports
Added database.close method
Added opts parameter to EdgeCollection#save
Added database.version method
Added database.login method
Added database.exists method
Added collection.exists method
Added graph.exists method
Added aql.literal function
Exposed typings for collections and graphs (@samrg472 in #538)
Fixed synchronous errors during request creation not being handled
Internal errors thrown while a request is created (e.g. malformed URIs) would result in unhandled errors, which could result in termination of the process or promises never being rejected. These errors are now handled normally and will result in async rejections as expected.
res.body is an empty string instead of null in the browser versionFixed collection.update(documentHandle, newValue, opts) missing return value
Fixed collection.removeByKeys(keys, options) missing return value
Fixed collection.replaceByExample(example, newValue, opts) missing return value
Fixed collection.updateByExample(example, newValue, opts) missing return value
Replaced Object.values use to improve Node version compatibility
This allows using arangojs in Node.js 6 LTS without a polyfill.
Moved most documentation out of the README (#123)
This is a necessary step to integrate arangojs with the Drivers book in the official ArangoDB documentation.
Replaced internal use of async functions with callbacks
This removes some unnecessary layers of indirection, which should increase overall performance.
Extended db.transaction arguments (@f5io in #494)
It’s now possible to pass additional transaction options.
Fixed a typo (@lodestone in #506)
Fixed graphEdgeCollection.edge return value (@Hunter21007 in #501)
Fixed graph API sending incorrect requests resulting in HTTP 400 errors (@casdevs in #513)
Removed ES modules build
This should solve compatibility problems with es6-error. The cjs
build now should also work with emulated ES module imports.
Use cpy-cli for build process
Should help with cross-platform compatibility.
Fixed db.uninstallService(mount, opts) opts default value
Fixed db.getServiceConfiguration(mount, minimal) minimal representation
Fixed db.getServiceDependencies(mount, minimal) minimal representation
Fixed db.updateServiceConfiguration(mount, cfg, minimal) non-minimal representation
Fixed db.replaceServiceConfiguration(mount, cfg, minimal) non-minimal representation
Fixed db.updateServiceDependencies(mount, cfg, minimal) non-minimal representation
Fixed db.replaceServiceDependencies(mount, cfg, minimal) non-minimal representation
Fixed handling of non-json responses
Use rimraf for build process
Should help with cross-platform compatibility.
Fixed some imports broken during the TypeScript rewrite
If you were previously seeing errors involving a default property,
this should make those go away.
Removed retryConnection config.
It is not possible to reliably determine whether retrying a request is safe or not at the driver level. If you need automatic retry, you should implement your own logic, e.g. using the retry package.
Removed promise config.
If you want to use an alternative promise implementation
you need to overwrite the Promise global variable directly.
Asynchronous functions no longer support node-style callbacks.
All asynchronous functions now return promises.
Removed support for credentials in url config.
Use db.useBasicAuth or db.useBearerAuth to pass credentials instead.
Removed bower support.
Use yarn/npm instead.
Removed lib path prefix
All arangojs files can now be imported directly by name.
Before:
import { DocumentCollection } from "arangojs/lib/collection";
After:
import { DocumentCollection } from "arangojs/collection";
The url config can now also be an array of URLs.
The behavior depends on the load balancing strategy (see API docs).
The databaseName config has been replaced with isAbsolute.
If you previously used databaseName: false, the same behavior can now
be achieved using isAbsolute: true. If you want to use a specific
database you can still switch databases with db.useDatabase at any time.
Browser: maximum number of parallel connections behaves differently.
As keep-alive does not work reliably in the browser, the maximum number
of parallel connections now matches agentOptions.maxSockets exactly.
TypeScript: ported arangojs to TypeScript.
The generated typings are now included in the NPM release and should be more reliable than the community maintained typings included with earlier versions of arangojs. See also #480.
Added ES Modules and browser build to NPM release.
lib/esm/lib/cjs/lib/web.jsAdded support for load balancing and failover.
See API documentation for details.
Added acquireHostList method.
See API documentation for details.
Added support for leader/follower failover.
Connections to a follower responding with an endpoint redirect will now be transparently redirected to the indicated leader.
Fixed #354
Graph methods now only return the relevant part of the response body.
