@commitlint/config-nx-scopes

Lint your nx project commits

Shareable commitlint config enforcing nx project and workspace names as scopes. Use with @commitlint/cli and @commitlint/prompt-cli.

Scopes are read from the nx project graph, so a project contributed by an nx plugin is a valid scope even though it has no project.json or package.json of its own.

Getting started

npm install --save-dev @commitlint/config-nx-scopes @commitlint/cli
echo "module.exports = {extends: ['@commitlint/config-nx-scopes']};" > commitlint.config.js

Filtering projects

You can filter projects by providing a filter function as the second parameter to getProjects(). The function will be called with an object containing each projects' name, projectType, and tags. Simply return a boolean to indicate whether the project should be included or not.

As an example, the following code demonstrates how to select only applications that are not end-to-end tests.

In your .commitlintrc.js file:

async function getConfig() {
  const {
    default: {
      utils: { getProjects },
    },
  } = await import("@commitlint/config-nx-scopes");

  return {
    rules: {
      "scope-enum": async (ctx) => [
        2,
        "always",
        [
          ...(await getProjects(
            ctx,
            ({ name, projectType }) => !name.includes("e2e") && projectType == "application",
          )),
        ],
      ],
    },
    // . . .
  };
}

module.exports = getConfig();

Here is another example where projects tagged with 'stage:end-of-life' are not allowed to be used as the scope for a commit.

In your .commitlintrc.js file:

async function getConfig() {
  const {
    default: {
      utils: { getProjects },
    },
  } = await import("@commitlint/config-nx-scopes");

  return {
    rules: {
      "scope-enum": async (ctx) => [
        2,
        "always",
        [...(await getProjects(ctx, ({ tags }) => !tags.includes("stage:end-of-life")))],
      ],
    },
    // . . .
  };
}

module.exports = getConfig();

Examples

❯ cat commitlint.config.js
{
  extends: ['@commitlint/config-nx-scopes']
}

❯ tree packages

❯ echo "build(api): change something in api's build" | commitlint

❯ echo "test(foo): this won't pass" | commitlint
⧗   --- input ---
