nationalarchives / tdr-generated-graphql   0.0.391

This project generates, packages and deploys the case classes generated by the sbt-graphql project to the sonatype nexus.

These classes are used by other TDR repositories to communicate with the consignment API.

1. Add a new query file to src/main/graphql:
   • The file name should be in Pascal case e.g. FooBarBaz
   • The query/mutation name should be in Camel case e.g. fooBarBaz
2. Download the latest graphql schema file into the src/main/resources directory
3. Run the following commands to allow you to check that your changes work locally before submitting them:

• sbt package publishLocal

This will place a snapshot version of the built project jar in the local .ivy cache folder: $HOME/.ivy2/local/uk.gov.nationalarchives/tdr-generated-graphql_2.13/[version number]-SNAPSHOT

Other sbt projects that have this project as a dependency can access the local snapshot version by changing the version number in their build.sbt file, for example:

... other dependencies...
"uk.gov.nationalarchives" %% "tdr-generated-graphql" % "[version number]-SNAPSHOT"
... other dependences...

The following commands create a symbolic link to the generated Typescript version of the schema.

1. In this project: cd ts
2. In the ts directory: npm run codegen
3. In the ts directory: npm link
   • From the output of this command copy the following line: @nationalarchives/tdr-generated-graphql.
4. Navigate to the project that uses the generated schema in its Typescript code. In this project navigate to the relevant npm directory and run this command in that directory: npm link @nationalarchives/tdr-generated-graphql

See the following blog post for more information on npm link and instructions to undo the symbolic link: https://medium.com/@alexishevia/the-magic-behind-npm-link-d94dcb3a81af

• Commit and push the new query file that sits in src/main/graphql
• Open a pull request.
• A job will run which will check to see if the changes are only within the ts directory. If they are, the ts-only label is added to the pull request.
• If the pull request later changes to include other changes, the ts-only label is removed.
• Merge the pull request to master once it has been reviewed.
• If the PR has the ts-only label, the updated package is deployed to npm but not to maven.
• If the PR doesn't have the ts-only label, updated packages are deployed to npm and maven.

• Go to the TDR Deploy Generated Graphql on the GitHub Actions tab of this project.
• Click on 'Run Workflow'.
• Select green 'Run Workflow' button.
• You should see the job running (if not, refresh the page).
• Once it is complete (green tick), check the release tags to see the new version.
• It should take about 15-30 minutes until it is published to Maven.
  • Note: the new release version is often available before it appears on the Maven GUI.
