@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.

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();
