CHANGELOG.md

master

0.8.1 (April 27, 2016)

• RelayNetworkDebug now logs query variables.
• RelayNetworkDebug is now added as a subscriber instead of replacing any existing network layers. It also no longer replaces the global fetch.
• Relay.Environment#injectNetworkLayer (and, by extension Relay#injectNetworkLayer) will now warn if injecting would overwrite a previously injected layer.
• Added experimental low-level RelayGraphQLMutation API (still being finalized and not yet documented, so use at your own risk).

0.8.0 (April 11, 2016)

• Added a React Native / Relay TodoMVC example app.
• You can now render multiple Relay apps at once, each with their own store. The following APIs are early versions and are as of yet undocumented so please use them with caution.
  • Added Relay.Environment. Relay.Store is now simply a global instance of RelayEnvironment. To create your own isolated store and network subsystem, create a new RelayEnvironment() and make use of it wherever environment is required.
  • Use Relay.Environment#injectNetworkLayer to inject a custom network layer for use within the context of a particular Relay.Environment instance.
  • Added Relay.ReadyStateRenderer. This component takes in an instance of Relay.Environment, a queryConfig that conforms to the RelayQueryConfigInterface, and a Relay container. It renders synchronously based on the supplied readyState. This primitive enables you to create alternatives to Relay.Renderer that fetch and handle data in a custom way (eg. for server rendered applications).
  • Added Relay.Renderer – a replacement for Relay.RootContainer that composes a Relay.ReadyStateRenderer and performs data fetching. Relay.RootContainer is now a wrapper around Relay.Renderer that substitutes Relay.Store for environment.
• Renamed the Flow type RelayRendererRenderCallback to RelayRenderCallback.
• Renamed the Flow type RelayQueryConfigSpec to RelayQueryConfigInterface.
• RelayContainer.setVariables will no longer check if the variables are changed before re-running the variables. To prevent extra work, check the current variables before calling setVariables.
• You can now roll back mutations in the COMMIT_QUEUED state using RelayMutationTransaction#rollback.
• When specifying a NODE_DELETE or RANGE_DELETE mutation config, you can omit parentID if your parent, in fact, does not have an ID.
• In cases where you query for a field, but that field is unset in the response, Relay will now write null into the store for that field. This allows you to return smaller payloads over the wire by simply omitting a key in the JSON response, rather than to write an explicit fieldName: null.
• If the relay prop does not change between renders, we now recycle the same object. This should enable you to make an efficient this.props.relay === nextProps.relay comparison in shouldComponentUpdate.
• You can now craft a connection query having invalid combinations of connection arguments (first/last/after/before) so long as the values of those arguments are variables and not concrete values (eg. friends(first: $first, last: $last) will no longer cause the Relay Babel plugin to throw).
• Added runtime validation to mutation configs to help developers to debug their Relay.Mutation.
• Added RelayNetworkDebug. Invoke require('RelayNetworkDebug').init(Relay.DefaultNetworkLayer) to enjoy simple to read logs of your network requests and responses on the console. Substitute your own network layer if you use one.
• Added two new rangeBehaviors:
  • IGNORE means the range should not be refetched at all.
  • REFETCH will refetch the entire connection.
• Connection diff optimization: Enables a mode where Relay skips diffing information about edges that have already been fetched. This can be enabled by adding @relay(variables: ['variableNames']) to a connection fragment.

0.7.3 (March 4, 2016)

• The instance of Babel that the babel-relay-plugin receives will now be used when making assertions about version numbers.

0.7.2 (March 4, 2016)

• Identifying arguments on root fields can now be of any type - boolean, number, string, or array/object of the the same.
• Fixes a bug when we read connections or fragments without allocating a record until we encounter a child field that is not null. We now ensure that we allocate the record for connections and fragments (if it exists) regardless.
• Made babelAdapter compatible with Babel 6.6
• npm run build now works on Windows
• Tests now pass when using Node 5 / NPM 3
• Passing an empty array as a prop corresponding to a plural fragment no longer warns about mock data. The empty array is now passed through to the component as-is.
• Removed uri from RelayQueryConfigSpec. The uri property was part of RelayRoute, but never RelayQueryConfig. This revision simply cleans up the Flow shape in RelayContainer.
• RelayRenderer now runs queries after mount to make sure RelayRenderer does not run queries during synchronous server-side rendering.

0.7.1 (February 18, 2016)

• Having fixed a bug, now you can actually interpolate an array of fragments into a Relay.QL query. eg. ${containers.map(c => c.getFragment('foo'))}

0.7.0 (February 12, 2016)

• Eliminated a race condition that would cause RelayGarbageCollector to fatal when, in the middle of a readRelayDiskCache traversal, a container attempts to subscribe to a record not yet registered with the garbage collector.
• The garbage collector now strictly increments references to all subscribed nodes, and strictly decrements references to all previously subscribed nodes, eliminating a class of race condition by ensuring an exact 1:1 correspondence of increment/decrement calls for a given node.
• Replaced GraphQLStoreDataHandler with RelayRecord, and added the RelayRecord#isRecord method.
• Introduced RelayQueryIndexPath which tracks fragment indexes to the nearest parent field during query traversal. This replaces the existing logic used to generate field serialization keys.
• Added RelayContext, a step toward making all Relay state contextual.
• Improved query printing performance via short circuiting and inlining.
• Moved record writing functions out of RelayRecordStore and into a new RelayRecordWriter class.
• The Babel plugin now prints canHaveSubselections metadata on object-like fields that can contain child fields, making it possible to determine if a given field in a query is a true leaf node, or an object-type field having no subselections. This replaces RelayQueryNode#isScalar with RelayQueryNode#canHaveSubselections.
• RANGE_DELETE mutation configs now allow you to specify an array path to a deleted node, rather than just a deletedIDFieldName.
• Renamed Records to RecordMap.
• Record reads from cache managers are now abortable. If the network request finishes before the cache read, for instance, the cache read can be cancelled.
• Added USERS.md; a catalog of products and developers that use Relay.
• You can now interpolate an array of fragments into a Relay.QL query. eg. ${containers.map(c => c.getFragment('foo'))}
• Fixed a bug where invalid queries could be printed due to different variables having the same value; duplicates are now avoided.

0.6.1 (January 8, 2016)

• Renamed RelayStore#update to RelayStore#commitUpdate. RelayStore#commit will be removed in v0.8.0. For an automated codemod that you can use to update your Relay app, visit https://github.com/relayjs/relay-codemod
• Replaced RelayTestUtils.unmockRelay(); with require('configureForRelayOSS'); in tests.
• Fragment names in printed queries are now less verbose.
• Fixed a bug that caused queries to be printed incorrectly.
• Eliminated concrete fragment hashes.
• Connections now handle repeated edges more gracefully.
• Created a new RelayTaskQueue class. Used it to back RelayTaskScheduler.
• Reduced memory by only storing paths to container root nodes.
• Renamed RelayTaskScheduler#await to RelayTaskScheduler#enqueue.
• Fixed a series of memory leaks with a new GC implementation.
• Tests now run with Jasmine 2.

0.6.0 (December 4, 2015)

• Bump the babel-relay-plugin version to v0.6.0 (now Babel 6 compatible).
• The keys in rangeBehaviors are now compared against the sorted filter arguments of a field. For the field foo(first: 10, b:true, a:false) the matching range behavior key will be 'a(false).b(true)'.
• Relay will now throw an invariant if range behavior keys are unsorted.
• Fragments are now supported in mutation fat queries.
• Added Relay.Store#applyUpdate method to create a transaction optimistically without committing it. Returns a transaction object that you can use to commit() or rollback().
• Added RelayStoreData#clearCacheManager method.
• Renamed RelayQuery#getHash to RelayQuery#getConcreteFragmentHash
• Removed RelayQueryPath#toJSON and RelayQueryPath#fromJSON

0.5.0 (November 11, 2015)

• Bump the babel-relay-plugin version to v0.4.1.
  • Added validation of arguments for connections with edges or pageInfo.
    • Connections without arguments in fat queries can add the new fragment directive @relay(pattern: true).
  • Fixed validation of fields within inline fragments in connections.
  • Print queries using a plain-object representation (instead of GraphQL objects).
• RelayQueryField#getStorageKey will now produce the same key regardless of the order of a field's arguments.
• Range behavior keys in mutation configs are now guaranteed to be sorted.
• Added the Relay.createQuery() function which returns a RelayQuery.Root (that can be used with Relay.Store methods).
• Optimistic response keys now use GraphQL OSS syntax. (Usage of old, call-like syntax is now deprecated and will warn.)
• Fix a bug where optimistic queries could cause the error "Could not find a type name for record ...".

0.4.0 (October 13, 2015)

• Bump the babel-relay-plugin version to v0.3.0.
  • Fixed the metadata for fields on abstract types.
  • Directives are now validated against the schema.
  • Mutations field arguments are now validated.
  • Non-root node(id: ...) fields are now invalid.
  • Added support for RelayQL template tag.
  • Improvements to validation and error messages.
• The __typename of abstract types are now fetched and stored locally.
• Fixed hasOptimisticUpdate returning true after mutation succeeds (#86).
• Fixed printing mutations with generated id fields (#414).
• Fixed updating views when removing the last element in a plural field (#401).
• Fixed sending mutations via classes without invalid GraphQL characters (#448).
• Added a __DEV__-only warning when data is passed down via the wrong prop.

0.3.2 (September 18, 2015)

• Bump the babel-relay-plugin version to v0.2.5.
  • Queries now preserve directives.
  • Output is now generated by babel.
• Fix refragmenting diff queries (#305).
• Directives are now printed.

• Rebuild to replace faulty NPM package (no code changes).

0.3.0 (September 11, 2015)

• Fix query variable printing for non-null and list types (#203).
• Bumped React dependency to v0.14.0-rc.
• Switched to using ReactDOM rather than React for performing batched updates (via unstable_batchedUpdates).
• Updated the babel-relay-plugin to v0.2.3:
  • Added support for compiling queries containing introspection fields such as __schema, __typename and such.
  • Use of field(before: ..., first: ...) or field(after: ..., last: ...) is now an error.
• Various improvements to documentation, warnings and error messages.

0.2.1 (September 1, 2015)

• Support simplified route query definitions (previous API still supported).

0.2.0 (August 28, 2015)

• Upgraded jest to 0.5 and switched Relay to use iojs v2+ only.
• Changed Relay.DefaultNetworkLayer constructor to take an init object instead of fetchTimeout and retryDelays.
• Scalars other than strings are now allowed as cursors, so long as they serialize to strings.
• Added npm run update-schema to update the test schema.

0.1.1 (August 14, 2015)

• The 'main' entrypoint can now be used in non-ES6 projects (now built w/ Babel).
• Instance methods of Relay.DefaultNetworkLayer are bound to the instance, facilitating reuse.
