🐛 Fixes

• Restore the ability to use environment or file references in the supergraph.yaml file - @​jonathanrainer PR #​2411

  In v0.26.3 and older you could use references such as ${env.HOST} or similar in the supergraph.yaml file, there was an oversight in the refactor and this was removed. This ability has now been restored.

v0.27.1

Compare Source

If using Rover with Connectors, you will need to specify APOLLO_ROVER_DEV_ROUTER_VERSION=2.0.0-preview.X when using rover dev

🐛 Fixes

• Create output parent directories if they do not already exist - @​dotdat PR #​2396

  One small regression with release of v0.27.0 was that if an output directory to supergraph compose was specified, but one of the parent directories did not exist, the command would fail. In previous versions the parent directories would be created instead and the command would succeed. This is now corrected and the previous behaviour restored.

• Clean up how default subgraphs are defined in rover dev - @​dotdat PR #​2397 fixes #​2394

  An issue has been reported where rover dev would prompt repeatedly for the subgraph name and URL despite the user having given those values already. This was due to multiple factors, including not accounting for CLI args in the default case and some faulty other faulty logic. This has now been restored.

• Refine how composition produces artifacts for targets - @​dotdat PR #​2398 fixes #​2393

  Due to changes in the supergraph binary from 2.9+, writing directly to a file is now supported. However, this feature is not available in earlier versions of supergraph. As such Rover should be responsible for orchestrating how the output from supergraph binary ends up in a file, rather than delegating that responsibility to the supergraph binary and thus being at the mercy of which version is used. This allowed a further refactor that eliminated complexity around composition outputs.

• Ensure credentials are checked when needed and not before - @​jonathanrainer PR #​2400 fixes #​2399

  Due to the rover dev refactor there were situations where credentials were being required when they were ultimately not being used. As such we stopped supporting the use case where no profile was defined and no APOLLO_KEY env var was provided, which is a very common pattern. This is now corrected.

🛠 Maintenance

Important: 3 potentially breaking changes below, indicated by ❗ BREAKING ❗

If using Rover with Connectors, you will need to specify APOLLO_ROVER_DEV_ROUTER_VERSION=2.0.0-preview.X when using rover dev

❗ BREAKING ❗

• Make paths in supergraph.yaml resolve relative to the location of the supergraph.yaml file - @​jonathanrainer PR #​2119

  To support the new Apollo Language Server it is now the case that any paths expressed in the supergraph.yaml file will be resolved relative to the file's location on disk, not the location that Rover is running in, at the time.

• Remove fed2 command - @​aaronArinder PR #​2222

  This was a deprecated, hidden, unused command that was for early Federation 2.0 testing. This command has not been invoked for a very long time.

• Remove ability to start multiple rover dev sessions - @​jonathanrainer PR #​2352

  Now that Rover supports hot-reloading from supergraph.yaml files we've removed the ability to start multiple rover dev sessions, in multiple terminal windows, and have them communicate with each other.

• Remove ambiguity around which URL is used for query execution when using subgraph_url and --graph-ref flag

  In previous versions of Rover, when the --graph-ref flag was used and a subgraph was specified in the supergraph.yaml to override the values from GraphOS, the schema.subgraph_url was used for both schema fetching via introspection and query execution.

  federation_version: 2.10.0
  subgraphs:
    subgraph_a:
      schema:
        subgraph_url: "http://localhost:4000/graphql"
  

  This was a bug in earlier versions of Rover that has only recently been identified. Now if this same situation occurs, Rover will use the given schema.subgraph_url (http://localhost:4000/graphql in the example above) to fetch the schema only. Query execution will use the routing_url from GraphOS.

  This is consistent with the documented behaviour since this feature launched and in addition is consistent with the principle that the use of the supergraph.yaml will only override --graph-ref where you explicitly state that should happen. To obtain the original behaviour again you simply need to override the routing_url in the supergraph.yaml as well, so the example above would become:

  federation_version: 2.10.0
  subgraphs:
    subgraph_a:
      routing_url: "http://localhost:4000/graphql"
      schema:
        subgraph_url: "http://localhost:4000/graphql"
  

  and this will use http://localhost:4000/graphql for query execution and schema fetching via introspection.

🚀 Features

• Apollo Language Server - @​jonathanrainer

  This brand-new feature aids in subgraph development and also supports connectors. It enhances Apollo tools such as the schema proposals editor and recent versions of IDE plugins and extensions by providing federation-aware syntax highlighting, validation, autocompletion, and more

• New version of rover dev - @​dotdat @​aaronArinder @​loshz @​monkpow @​jonathanrainer

  In this version of Rover there is a new version of rover dev built upon a completely new implementation of the composition pipeline inside of Rover. This not only allows a better functioning rover dev with more features, but it also supports the new Apollo Language Server, for use with Connectors!

  In addition, it also supports hot-reloading of the supergraph.yaml file, subgraphs can be added, removed or edited, and this will be all be reflected in the running rover dev session!

🐛 Fixes

• rover persisted-queries publish publishes clientNames in persisted query manifests - @​glasser #​2239

When using rover persisted-queries publish, if the JSON manifest file includes clientName fields on operations, those client names are now published instead of ignored. You can use the new --for-client-name option to set or override the clientName field for all operations in a persisted query manifest.

v0.26.2

Compare Source

🐛 Fixes

• Avoid misleading warning when --output is not specified - @​glasser #​2100

  In the release of v0.26.1 logic was added to disable the output flag if the Federation version was less than 2.9, however this was being printed even when the --output flag was not supplied. This has been corrected.

• Improve --graph-ref option - @​glasser #​2101

  In the release of v0.26.0 the --graph-ref option was added to supergraph compose as well as rover dev. However, the behaviour when --graph-ref was used in conjunction with --config did not work as documented. This is now fixed. Furthermore, both rover dev and supergraph compose, when using only the --graph-ref option, respect the graph ref's Federation version.

• Further improve --graph-ref option - @​glasser #​2105

  Improves on the above by fixing some corner cases that prevented #​2101 from working as intended

🚀 Features

• Respect the use of --output flag in the supergraph binary - @​aaronArinder PR #​2045

  In testing to attempt to reduce the runtime of supergraph compose we noticed that a very large proportion of the time spent (in the case of large supergraphs) was spent printing the result to stdout. With this change we add an --output flag to the supergraph binary which means this time can be reduced significantly, leading to much faster compositions.

• Add --license flag to rover dev - @​loshz PR #​2078

  Adds the ability to pass along an offline enterprise licence to the router when running rover dev

• Remove Rayon and reduce usage of Crossbeam - @​jonathanrainer PR #​2081

  Now that rover has transitioned to using an asynchronous runtime we don't need to use Rayon any more. This also resolves a bug whereby rover dev could lock up if passed a supergraph.yaml file with lots of subgraphs in.

• Introduce new print macros - @​loshz PR #​2090

  Adds three new macros to the codebase so that we can still visually distinguish between INFO, WARNING and ERROR log lines without the use of emoji

• Use new print macros in place of emoji - @​loshz PR #​2096

  Updates the locations that previously used emoji to utilise the new macros defined in the previous PR

🐛 Fixes

• Stop Windows Installer failing if whitespace is accidentally passed to the rover install command - @​jonathanrainer PR #​1975

  In some situations it was possible for whitespace to be passed to the rover install command which then caused the installer to fail. A guard has now been added to strip whitespace out before it is passed to the install command.
