Automate versioning, publishing, and deployments with Nx

Reusable Workflows
WorkflowVersionSource
Validate (PR version-plan check)v1validate-v1.yaml
Release (publish and deploy)v2release-v2.yaml

A reusable GitHub workflow that automates package versioning, publishing, and approval-gated Terraform environment deployments for Nx monorepos using Nx Release with version plans.

Features

  • ⚠️ Can show a pull request warning when changes need a version plan but none is present
  • 🔄 Automatically creates or updates a Version Packages pull request when new version plans are pushed to main
  • 📦 Publishes packages to npm when the Version Packages PR is merged
  • 🌍 Dispatches one independent plan/approval/apply workflow for each released Terraform environment
  • 🎯 Agnostic: Works with pnpm, yarn, and npm
  • ♻️ Idempotent: workflow_dispatch can recover missed tags or releases

How It Works

The workflow automates the release lifecycle in two steps:

  1. When you push a version plan to main — the workflow opens (or updates) a Version Packages pull request that bumps versions and updates changelogs automatically.
  2. When the Version Packages PR is merged — the workflow publishes the packages to npm with provenance, creates git tags and GitHub Releases, and dispatches one independent deployment workflow for each released Terraform environment. Package publishing completes without waiting for infrastructure approvals.

If you also enable the DX validation workflow, pull requests can receive a warning comment when the changes look releasable but the PR does not include a matching version plan.

Recovery

If package publishing or tag synchronization fails, re-run the action or trigger workflow_dispatch manually. Terraform deployments run separately: re-run the failed environment workflow, or manually dispatch it with the same project and source commit.

Prerequisites

  • Repository configured with nx.json (see nx.json configuration below)
  • npm packages require OIDC Trusted Publishing configured (id-token: write permission must be granted)
  • Public packages must be tagged as public in their Nx project configuration. The nx-release workflow treats any tag equal to public or ending with :public (for example, npm:public) as publishable.

Terraform environment releases additionally require:

  • an environment.json manifest and the inferred tf-plan-upload and nx-release-publish targets;
  • a workflow in the caller repository that accepts the Terraform deployment inputs. DX uses release-terraform-environment-v1.yaml;
  • paired plan/apply GitHub environments, with required reviewers configured on the apply environment;
  • self-hosted runners and cloud credentials available through those environments.

Marking a package as public

To mark a package as public, set "private": false in the package's package.json file. This is necessary for the publish workflow to process the package:

{
"name": "@pagopa/my-package",
"version": "1.0.0",
"private": false,
... other package.json fields
}

nx.json configuration

Add the following release block to your nx.json:

{
"release": {
"versionPlans": true,
"projects": [
"apps/*",
"packages/*",
... other project globs
],
"projectsRelationship": "independent",
"version": {},
"changelog": {
"projectChangelogs": {
"createRelease": false,
"file": "{projectRoot}/CHANGELOG.md",
"renderOptions": {
"authors": true,
"applyUsernameToAuthors": true,
"commitReferences": true,
"versionTitleDate": true
}
}
},
"git": {
"commit": false,
"tag": true,
"stageChanges": false
},
"releaseTag": {
"pattern": "{projectName}@{version}"
}
}
}
OptionValueWhy
versionPlanstrueEnables file-based versioning via version plans: version increments are described in dedicated files committed to the repo
projects["projects_path_1/*", ...]Glob patterns matching all projects to include in the release process; required for Nx to discover and release all packages
projectsRelationship"independent"Each package has its own version; there is no single workspace-wide version
createReleasefalseGitHub Releases are created automatically by the workflow after the PR is merged, not at changelog generation time
git.commitfalseThe workflow handles commits itself; letting Nx commit would interfere with the PR creation logic
git.tagtrueNx creates tags locally so the workflow can reference them; they are pushed only after the PR is merged
releaseTag.pattern{projectName}@{version}Follows the default Nx independent release convention; defining it explicitly improves clarity
note

The key renderOptions just adds some extra details to the changelog, but it doesn't affect the release process. You can omit it if you don't need those details (refer to the Nx documentation).

Usage

Use the release-v2.yaml reusable workflow. Create a .github/workflows/release.yaml file:

name: Release

on:
push:
branches:
- main
paths:
- ".nx/version-plans/**"
workflow_dispatch:

concurrency: ${{ github.workflow }}-${{ github.ref }}

jobs:
release:
name: Nx Release
permissions:
actions: write
contents: write
id-token: write
pull-requests: write
uses: pagopa/dx/.github/workflows/release-v2.yaml@main
with:
environment: npm-prod-cd
terraform-deployment-workflow: release-terraform-environment-v1.yaml
secrets:
app-client-id: ${{ secrets.GH_APP_RELEASE_CLIENT_ID }}
app-private-key: ${{ secrets.GH_APP_RELEASE_APP_KEY }}

Optional: enable the pull request warning

If you also want a warning comment on pull requests, add a validation workflow that uses validate-v1.yaml:

name: Validate

on:
pull_request:
types: [opened, synchronize]

jobs:
validate:
permissions:
contents: read
actions: read
pull-requests: write
uses: pagopa/dx/.github/workflows/validate-v1.yaml@main

With this in place, pull requests receive a warning only when a version plan is missing or incomplete.

Starting a Release

A release starts by committing a version plan to main. A version plan is a small file that records which packages changed and how their version should be bumped.

Pull Request Warning

When the optional validation workflow is enabled, a pull request can receive a warning comment if it changes something that should have a version plan but does not include one.

To clear the warning, add or fix the files in .nx/version-plans/ and push the update. The comment is refreshed automatically and disappears when everything is covered.

1. Generate the version plan

From the root of the repository, run:

npx nx release plan

The command is interactive: it will ask which packages to include and what bump type to apply (patch / minor / major / prerelease / prepatch / preminor / premajor). At the end it writes a file under .nx/version-plans/.

For more details see the Nx version plans documentation.

2. Commit and push

git add .nx/version-plans/
git commit -m "feat: update @pagopa/my-package"
git push origin main

Pushing to main triggers the workflow, which opens (or updates) the Version Packages PR automatically. Merging that PR publishes packages and dispatches released Terraform environments without waiting for their approval gates.

info

The direct push to main is a simplified flow for demonstration purposes. In a real-world scenario, you might want to create a PR for the version plan changes as well.

Troubleshooting

Version Packages PR is not created

  • Ensure .nx/version-plans/ contains version plan files on main
  • Verify the GitHub token has pull-requests: write permission
  • Run nx release --dry-run locally to check for errors

PR warning comment is not created

  • Ensure the validation workflow runs on pull_request
  • Ensure the PR really needs a version plan
  • Ensure the PR includes the correct files in .nx/version-plans/
  • The warning is only managed on same-repository pull requests

Publish fails

  • Verify that packages have the npm:public tag in their Nx configuration
  • Check that OIDC trusted publishing is configured on npm
  • Ensure id-token: write permission is granted to the workflow

Terraform deployment is not dispatched

  • Ensure the release caller grants actions: write
  • Ensure terraform-deployment-workflow names a workflow file in the caller repository
  • Check that the Version Packages PR contains valid nx-release-tags metadata
  • Verify that the released project has a valid environment.json

Terraform deployment fails or is rejected

Re-run the independent environment workflow. For recovery outside the original run, dispatch release-terraform-environment-v1.yaml manually with the released project, source commit, GitHub environment names, and runner label.

Git tags or GitHub Releases are missing

Trigger workflow_dispatch manually. The action scans all past merged Version Packages PRs and creates any tags and releases still missing.
