We highly recommend to use Yarn when you think to contribute to this project.

$ yarn add detect-next-version

Monorepo support

For making it work on monorepo setups, you should pass options.packages - an array of package names that are changes and a options.cwd - the root of the monorepo. Usually this can be extracted from commit message or the response of lerna changed.

import detectNextVersion from 'detect-next-version';

async function main() {
  // e.g. /home/charlike/develop/some-monorepo
  const cwd = process.cwd();

  // try using `git-commits-since` for getting all commits
  // it returns an object with `rawCommits` property
  const commits = ['feat: foo bar', 'chore(ok): qux okey'];
  const packages = ['@tunnckocore/qq5', 'foo-bar-baz-qux'];

  const results = await detectNextVersion(commits, { packages, cwd });
  console.log(results);

  const [itemOne, itemTwo] = results;
  console.log(itemOne.name); // => '@tunnckocore/qq5'
  console.log(itemOne.path); // => '@tunnckocore/qq5'
  console.log(itemOne.increment); // => 'minor'
  console.log(itemOne.lastVersion); // => '0.1.0'
  console.log(itemOne.nextVersion); // => '0.2.0'
  console.log(itemOne.cwd); // => /home/charlike/develop/some-monorepo

  console.log(itemTwo.name); // => 'foo-bar-baz-qux'
  console.log(itemTwo.path); // => 'packages/foo-bar-baz-qux'
  console.log(itemTwo.increment); // => 'minor'
  console.log(itemTwo.lastVersion); // => '1.0.4'
  console.log(itemTwo.nextVersion); // => '1.1.0'
  console.log(itemTwo.cwd); // => /home/charlike/develop/some-monorepo
}

main().catch(console.error);

src/index.js

detectNextVersion

Calculates next version of given package with name, based given commitMessages which should follow the Conventional Commits Specification. Options are passed directly to @tunnckocore/package-json and recommended-bump packages. Also because the recommended-bump, you can pass options.plugins which will be passed to parse-commit-message commit message parser. So follow their docs and see the tests here for example usage. If all commit messages are of type that is not patch|fix|minor|feat|major or containing BREAKING CHANGE: label (e.g. the chore type), then the returned result won't have nextVersion and increment will be false.

ProTip: See parse-commit-message types documentation!

Params

• commits {string|} directly passed to recommended-bump May be one of string, Array<string> or Array<Commit>
• [options] {object} optional, passed to above mentioned packages.

Returns

• Array<object> an array of objects where each is basically the return of recommended-bump plus { pkg, name, cwd, path, lastVersion, nextVersion? }.

Examples

type Commit = {
  header: Header;
  body?: string | null;
  footer?: string | null;
  increment?: string | boolean;
  isBreaking?: boolean;
  mentions?: Array<Mention>;
};

import detector from 'detect-next-version';

async function main() {
  const commits = ['chore(ci): some build tweaks', 'fix(cli): foo bar'];

  // consider `my-npm-package` is version 0.1.0
  const [result] = await detector(commits, { name: 'my-npm-package' });
  console.log(result.increment); // => 'patch'
  console.log(result.pkg); // => package's latest package.json metadata
  console.log(result.lastVersion); // => '0.1.0'
  console.log(result.nextVersion); // => '0.1.1'
  console.log(result.patch[0].header.type); // => 'fix'
  console.log(result.patch[0].header.scope); // => 'cli'
  console.log(result.patch[0].header.subject); // => 'foobar'
  console.log(result.patch[0].header.toString()); // => 'fix(cli): foobar'
}

main().catch(console.error);

import { parse } from 'parse-commit-message';
import detector from 'detect-next-version';

async function main() {
  const commitOne = parse('fix: foo bar');
  const commitTwo = parse('feat: some feature subject');

  // always an array, but we can destruct it here,
  // because we know that it has only one item
  const [result] = await detector([commitOne, commitTwo], {
    name: '@my-org/my-awesomepkg',
  });
  console.log(result.increment); // => 'minor'
}

main().catch(console.error);
