What is jest-changed-files?

The jest-changed-files npm package is a utility that allows you to determine which files have changed in a git or hg (Mercurial) repository. It is often used in testing environments, particularly with Jest, to identify which tests need to be run based on the changes made to the codebase.

What are jest-changed-files's main functionalities?

Getting changed files from a Git repository

This feature allows you to get a list of files that have changed since the last commit in a Git repository. The 'lastCommit' option specifies that only changes from the last commit should be considered.

const { getChangedFilesForRoots } = require('jest-changed-files');

(async () => {
  const changedFiles = await getChangedFilesForRoots(['./'], { lastCommit: true });
  console.log(changedFiles.changedFiles);
})();

Getting changed files from a Mercurial repository

This feature is similar to the previous one but is used for Mercurial repositories. The 'withAncestor' option can be used to find changes that have occurred since the last common ancestor of the current head and the default branch.

const { getChangedFilesForRoots } = require('jest-changed-files');

(async () => {
  const changedFiles = await getChangedFilesForRoots(['./'], { withAncestor: true });
  console.log(changedFiles.changedFiles);
})();
