If sinceCommit is present, gitToJs will return logs for commits after the commit specified.

const { gitToJs } = require('git-parse');

const commitsPromise = gitToJs('path/to/repo/');

commitsPromise.then(commits => console.log(JSON.stringify(commits, null, 2)));

.checkOutCommit(pathToRepo, commitHash, [options])

Checks a repository out to a given commit. hash is the commit hash. Options is an optional object with one property, force. force adds --force to the underlying git checkout. Returns a promise.

Runs 'git pull' on the repository at the given path. Returns a promise.

.gitDiff(pathToRepo, commitHash1, [commitHash2], [file])

Returns a git diff given a path to the repo, a commit, an optional second commit, and an optional file path.
