Semantic-release-nx NPM

semantic-release-nx

Apply semantic-release's automatic publishing to a monorepo managed by Nx.

Why

This library is a fork of semantic-release-monorepo, which allows you to use semantic-release with a single repository containing many npm packages, with configuration for use in an Nx workspace.

We want to attribute only commits that affect the package being released with semantic-release.

semantic-release-monorepo filters analyzed commits by package path. However, Nx builds apps/libraries in a dist folder whilst commits are being made to files in apps or libs.

How

Instead of attributing all commits to a single package, commits are assigned to packages based on the files that a commit touched.

If a commit touched a file in an Nx project, it will be considered for that package's next release. A single commit can belong to multiple packages and may trigger the release of multiple packages.

In order to avoid version collisions, generated git tags are namespaced using the given package's name: <package-name>-<version>.

Install

Add semantic-release and semantic-release-nx to your Nx repo.

yarn add semantic-release semantic-release-nx --dev

Usage

Add a release target for the packages that you want to semantically release.
Run semantic-release in the executor commands and apply semantic-release-nx via the extends option. You can pass in your own configuration here.

{
  "projects": {
    "<my-lib>": {
      "targets": {
        "release": {
          "executor": "@nrwl/workspace:run-commands",
          "dependsOn": [{ "target": "build", "projects": "self" }],
          "options": {
            "commands": [
              {
                "command": "semantic-release -e semantic-release-nx",
                "cwd": "libs/<my-lib>"
              }
            ]
          }
        }
      }
    }
  }

Add "nx release" to your CI.

You can release all affected packages with:

nx affected --target=release

Advanced

This library modifies the context object passed to semantic-release plugins in the following way to make them compatible with an Nx workspace.

Step	Description
`analyzeCommits`	Filters `context.commits` to only include the given monorepo package's commits.
`generateNotes`	Filters `context.commits` to only include the given monorepo package's commits.Modifies `context.nextRelease.version` to use the monorepo git tag format. The wrapped (default) `generateNotes` implementation uses this variable as the header for the release notes. Since all release notes end up in the same Github repository, using just the version as a header introduces ambiguity.

tagFormat

Pre-configures the tagFormat option to use the monorepo git tag format.
