API

Simple usage

Without any options get-changed-files assumes that master is the main branch to compare it against current branch and also uses default strategy for determining diff point (point in history from which to start getting changes).

const getChangedFiles = require("get-changed-files");
getChangedFiles().then(results => console.log(results));
/**
 * Outputs:
 * {
 *   "changed": [
 *     "some-old-changed-file.js",
 *     "package.json",
 *     "new-file.js"
 *   ],
 *   "uncommitted": [
 *     "package.json"
 *   ],
 *   "untracked": [
 *     "new-file.js"
 *   ]
 * }
 */

Changing main branch

const getChangedFiles = require("get-changed-files");
getChangedFiles({ mainBranch: "develop" }).then(results =>
  console.log(results)
);

Custom get diff point strategy

const getChangedFiles = require("get-changed-files");
const customGetDiffPoint = ({ currentBranch, mainBranch }) => {
  // do some magic...
  return { commit: commit_hash_from_which_to_start_getting_changes };
};
getChangedFiles({ customGetDiffPoint }).then(results => console.log(results));

CLI

Also get-changed-files adds a CLI tool get-changed.
