v8.4.1

Fixed

• Fixed default return type of AQL queries being undefined instead of any (#797)

v8.4.0

Changed

• Fetching additional cursor results now uses POST instead of PUT (DE-605)

  The POST route was deprecated and the PUT route is supported in all
  actively maintained versions of ArangoDB.

• User management methods now use database-relative URLs (DE-606)

  Previously these methods would make requests without a database prefix,
  implicitly using the _system database.

• aql template strings now take a generic type argument

  This allows explictly setting the item type of the ArrayCursor returned by
  db.query when using aql template strings. Note that like when setting
  the type on db.query directly, arangojs can make no guarantees that the
  type matches the actual data returned by the query.

  const numbers = await db.query(aql<{ index: number; squared: number }>`
    FOR i IN 1..1000
    RETURN {
      index: i,
      squared: i * i
    }
  `);
  const first = await numbers.next(); // { index: number; squared: number; }
  console.log(first.index, first.squared); // 1 1

Fixed

• Fixed listUsers behavior (#782)

• Fixed graph.create not correctly handling isDisjoint option

Added

• Added missing attributes to QueryInfo and MultiExplainResult.stats types (DE-607)

• Added cluster rebalancing methods to Database (DE-583)

• Added db.withTransaction helper method for streaming transactions (#786)

  This method allows using streaming transactions without having to manually
  begin and commit or abort the transaction.

  const vertices = db.collection("vertices");
  const edges = db.collection("edges");
  const info = await db.withTransaction([vertices, edges], async (step) => {
    const start = await step(() => vertices.document("a"));
    const end = await step(() => vertices.document("b"));
    return await step(() => edges.save({ _from: start._id, _to: end._id }));
  });

v8.3.1

Changed

• Added note that Simple Queries traversals are removed in ArangoDB 3.12.

v8.3.0

Fixed

• Fixed updateUser and replaceUser behavior (#783)

Added

• Added renewAuthToken method to Database (#784)

  This method allows refreshing the authentication token passed to the
  useBearerAuth method or used by the login method. Note that ArangoDB
  will currently only return a new token if the token is going to expire
  in the next 150 seconds.

• Added returnOld and mergeObjects to CollectionInsertOptions type

  These options are only available when using overwriteMode.

• Added caching options to InvertedIndex and ArangoSearchView types

  These options were added in ArangoDB 3.10.2.

• Added support for ArangoSearchView type storedValues shorthand notation

  Instead of using an object, attributes can also be defined as arrays of
  strings and arrays of arrays of strings. This was added in ArangoDB 3.10.3.

• Added peakMemoryUsage and executionTime to SingleExplainResult.stats type

  These attributes were added in ArangoDB 3.10.4.

• Added geo_s2 Analyzer types

  This Analyzer was added in ArangoDB 3.10.5.

• Added refillIndexCaches option to document operation options types

  This option was added in ArangoDB 3.11.

• Added optimizeTopK to ArangoSearchView and InvertedIndex types

  This option was added in ArangoDB 3.11.

• Added support for allowRetry option in db.query

  This feature was added in ArangoDB 3.11.

• Added x-arango-driver header

  The arangojs driver now correctly identifies itself to ArangoDB, allowing the
  ArangoGraph Insights Platform to take advantage of the driver's support for
  cloud-optimized behaviors.

v8.2.1

Fixed

• Fixed a bug in search parameter handling in the browser version

  Previously the browser version would incorrectly handle search parameters,
  which could result in invalid request URLs in many cases.

v8.2.0

Changed

• Index names are now automatically NFC-normalized (DE-506)

  This change affects all index names using unicode characters. The change
  has no effect when using non-unicode (ASCII) names.

  Any names used when creating/ensuring indexes or passed to any methods that
  expect an IndexSelector will automatically be NFC normalized.

• Internal querystring handling logic now uses URLSearchParams instead of
  node querystring module

  This change should be backwards compatible but may produce different results
  when relying on undefined behavior in custom (e.g. Foxx) routes.

v8.1.0

Added

• Added support for new ArangoDB 3.9.5 cache field in ArangoSearch types

v8.0.0

This is a major release and breaks backwards compatibility.

See the migration guide for detailed instructions
for upgrading your code to arangojs v8.

Removed

• Removed Node.js 10 and Node.js 12 support

  With Node.js 10 and 12 having reached their end of life, arangojs will no
  longer support these versions of Node.js going forward.

• Removed Internet Explorer and older browser support

  As of version 8 arangojs uses the Browserlist defaults
  list to generate the pre-built browser bundle, which excludes older browsers
  and specifically all versions of Internet Explorer.

  You may still be able to use arangojs in some of the excluded browsers when
  bundling arangojs yourself but this may require polyfills and additional
  transformations.

• Removed Dict type from connection module

  The Dict<T> type was identical to Record<string, T> and has been replaced
  with this built-in type across arangojs.

• Removed workaround for ArangoDB pre-3.2.8 Foxx HTTP API responses

  When fetching or modifying the configuration or dependencies of a Foxx
  service using ArangoDB 3.2.7 and earlier, arangojs would perform additional
  operations to convert the server response to a compatible format. All
  affected versions of ArangoDB have reached End of Life since December 2018.

• Removed deprecated db.useDatabase method

  The method was previously deprecated and can be replaced with db.database,
  which returns a new Database object instead of modifying the existing one.

• Removed deprecated MMFiles methods and types

  The MMFiles storage engine was removed in ArangoDB 3.7.

• Removed deprecated minReplicationFactor option from collection and
  database related types

  This option was renamed to writeConcern in ArangoDB 3.6.

• Removed deprecated overwrite option from CollectionInsertOptions type

  This option was deprecated in ArangoDB 3.7 and should be replaced with the
  overwriteMode option.

• Removed internal request.host attribute

  This attribute has been replaced with request.hostUrl.

• Removed internal response.arangojsHostId attribute

  This attribute has been replaced with response.arangojsHostUrl.

• Removed CollectionStatus and CollectionType enum re-exports

  Previously these would be re-exported by the arangojs module for backwards
  compatibility. If you still need to access these enums, you can import them
  from the collection sub-module instead. Note that the ViewType enum
  has been removed completely.

Changed

• Changed default URL to http://127.0.0.1:8529 to match ArangoDB default

  Previously arangojs would use localhost which on some systems resolves to
  the IPv6 address ::1 instead, resulting in confusing connection errors.

• Changed TypeScript compilation target to ES2020

  Since all evergreen browsers including Firefox ESR and all active Node.js LTS
  releases fully support ES2020, the compilation target for the browser bundle
  and Node.js has been moved from ES2016 and ES2018 respectively to ES2020.

• Updated TypeScript to version 4.8

  This may result in type signatures that are incompatible with TypeScript 3
  being added in future releases (including patch releases).

• Changed default behavior of internal db.request method

  Previously this method would always return the full response object if no
  transform callback was provided. The method now defaults to a transform
  callback that extracts the response body instead. The previous behavior can
  still be forced by passing false instead of a callback function.

  This change has no effect on other methods like route.request.

• Replaced node core module polyfills with native APIs in browser build

  As part of upgrading to webpack 5, arangojs now no longer requires node core
  modules to be polyfilled to work in the browser. This also drastically
  reduces the file size of the pre-built browser bundle arangojs/web.

• db.query now supports a generic return type (#764)

  This allows explictly setting the item type of the ArrayCursor returned by
  the query without using a type assertion on the promise result. Note that
  arangojs can make no guarantees that the type matches the actual data
  returned by the query.

  const numbers = await db.query<{ index: number; squared: number }>(aql`
    FOR i IN 1..1000
    RETURN {
      index: i,
      squared: i * i
    }
  `);
  const first = await numbers.next();
  console.log(first.index, first.squared); // 1 1

• Moved aql.literal and aql.join into aql module

  Previously these were available as methods on the aql function. Now they
  need to be imported from the aql module.

• Changed return values of db.getUserAccessLevel and db.getUserDatabases
  to match documented return types

• Retry requests resulting in status 503 ArangoError (#710)

  Unless retries are explicitly disabled by setting config.maxRetries to
  false, requests will now also be retried if the server responded with a
  503 ArangoError, which ArangoDB uses to indicate the server is running in
  maintenance mode. Previously this would always result in an error.

• Extended CursorExtras type in TypeScript

  The types of the attributes plan, profile, and stats are now defined
  more explicitly.

• Changed behavior of collection.removeAll for non-string arrays

  Previously collection.removeAll would always convert its argument into an
  array of document IDs and fail with an error if passed any documents had an
  ID not matching the collection name. Now the selector argument is passed
  as-is, bypassing this validation but allowing ignoreRevs to be respected
  by the server.

• Extracted type ArangoSearchViewLinkOptions from ArangoSearchViewLink

  Note that ArangoSearchViewLink now represents the type of the value
  returned by the server, marking several properties as required.

• Extracted type CreateArangoSearchView from
  ArangoSearchViewPropertiesOptions

  Note that ArangoSearchViewPropertiesOptions now includes only those options
  that can be updated/replaced whereas CreateArangoSearchView also includes
  options that can only be set during creation of a view.

• Renamed type GraphCreateOptions to CreateGraphOptions

• Renamed type PrimarySortCompression to Compression

• Replaced type AnalyzerInfo and all its constituent types

  Previously each type of Analyzer was represented by an AnalyzerInfo type
  and (where relevant) an AnalyzerProperties type, which were used for both
  creating and fetching Analyzers. The new types more closely follow the
  pattern already used for index types, providing pairs of
  CreateAnalyzerOptions and AnalyzerDescription types.

• Removed enum ViewType, type ArangoSearchView and changed View class to
  be non-generic

  The View class now behaves analogous to the Analyzer class. The various
  types related to different view types have been restructured to more closely
  follow the pattern used for indexes and analyzers.

Deprecated

• Deprecated EnsureFulltextIndexOptions and FulltextIndex types

  Fulltext indexes have been deprecated in ArangoDB 3.10 and should be replaced
  with ArangoSearch.

• Deprecated BytesAccumConsolidationPolicy type

  The bytes_accum consolidation policy for views was deprecated in
  ArangoDB 3.7 and should be replaced with the tier consolidation policy.
  The type is also no longer supported in ArangoSearchViewPropertiesOptions.

Added

• Added toJSON method to system errors

  ArangoJS already adds the request object to system errors encountered
  while attempting to make network requests. This change makes it easier
  to serialize these error objects to JSON the same way ArangoError and
  HttpError objects can already be serialized.

• Added allowDirtyRead option to db.beginTransaction, trx.commit,
  trx.abort, collection.edges, collection.inEdges, collection.outEdges

  The option is only respected by read-only requests.

• Added support for ifMatch and ifNoneMatch options (#707)

• Added overwrite option to db.acquireHostList (#711)

  Setting this option to true will replace the current host list, removing any
  hosts no longer present in the cluster.

• Added new ArangoDB 3.10 legacyPolygons option to EnsureGeoIndexOptions
  and GeoIndex types

  Geo indexes created in ArangoDB pre-3.10 will implicitly default this option
  to true. ArangoDB 3.10 and later will default to false and use the new
  parsing rules for geo indexes.

• Added support for new ArangoDB 3.10 cacheEnabled and storedValues options
  in persistent indexes

• Added support for new ArangoDB 3.10 computed values in collections

• Added support for new ArangoDB 3.10 InvertedIndex type

• Added support for new ArangoDB 3.10 offset Analyzer feature

• Added support for new ArangoDB 3.10 minhash, classification and
  nearest_neighbors Analyzer types

• Added missing replicationFactor and writeConcern options to
  CollectionPropertiesOptions type

• Added missing commitIntervalMsec option to ArangoSearchViewProperties
  type

• Added missing deduplicate option to EnsurePersistentIndexOptions type
  (#771)

• Added missing unique option to EnsureZkdIndexOptions type

• Added missing deduplicate and estimates fields to...

v8.0.0-rc.1

  longer support these versions of Node.js going forward.

• Removed Internet Explorer support

  As of version 8 arangojs no longer maintains compatibility for IE11 in the
  pre-built browser bundle. You may still be able to use arangojs in IE11 when
