GitHub Action
Nx affected dependencies action
Are you deploying many different apps in your nx monorepo with dedicated workflows?
Are you looking for an alternative to nx affected that will only lint and test affected projects that are actually a dependency of the app you are deploying in one workflow?
Then this action is for you!
By combining nx affected and nx dep-graph --focus=theNameOfTheAppToDeploy we can create an intersection of these two lists to only get the affected projects that are actually a dependency of theNameOfTheAppToDeploy.
When providing the base and head parameters to the workflow they are directly passed into nx affected.
- name: Evaluate affected
uses: leanix/nx-affected-dependencies-action@v0.2.1
id: affected
with:
project: pathfinder
base: ${{ github.sha }}~1
head: ${{ github.sha }}
- name: Run Unit Tests (Affected)
if: steps.affected.outputs.isAffected == 'true'
env:
affectedDeps: ${{ steps.affected.outputs.affectedDeps }}
run: npx nx run-many --target=test --projects=$affectedDeps
Here's a snippet to generate the base and head inputs for a repository that uses the git-flow branching strategy:
- name: Get parameters for nx-affected-dependencies-action
id: affectedInputs
run: |
if ["${BRANCH##*/}" == "develop"] || ["${BRANCH##*/}" == "master"]; then
echo "::set-output name=base::origin/develop"
echo "::set-output name=head::"
else
echo "::set-output name=base::$COMMIT_SHA~1"
echo "::set-output name=head::$COMMIT_SHA"
fi
env:
BRANCH: ${{ github.ref }}
COMMIT_SHA: ${{ github.sha }}
- name: Evaluate affected
uses: leanix/nx-affected-dependencies-action@v0.2.1
id: affected
with:
project: pathfinder
base: ${{ steps.affectedInputs.outputs.base }}
head: ${{ steps.affectedInputs.outputs.head }}
Instead of emulating git-flow with base and head parameters you can also just set the git-flow workflow parameter to true and we'll handle it for you.
Like this:
- name: Evaluate affected
uses: leanix/nx-affected-dependencies-action@v0.2.1
id: affected
with:
project: pathfinder
gitflow: true
- name: Run Unit Tests (Affected)
if: steps.affected.outputs.isAffected == 'true'
env:
affectedDeps: ${{ steps.affected.outputs.affectedDeps }}
run: npx nx run-many --target=test --projects=$affectedDeps
Execute npm run test to run unit tests with Jest.
Actions are run from GitHub repos so we will checkin the packed dist folder.
Run the following commands to tag your new version.
$ npm run package
$ git add dist
$ git commit -a -m "Meaningful commit message"
$ git tag -a v0.x.x -m "Release 0.x.x"Then draft a new release via the GitHub repository UI.
