Overview
@conventional-changelog/git-client is a Simple git client for conventional changelog packages.

PoC
- Install
@conventional-changelog/git-client@1.0.1or earlier - Prepare a Git directory to be used as source
- Create the following script for the proof-of-concept:
import { GitClient, } from "@conventional-changelog/git-client";async function main() { const gitDirectory = "/tmp/some-git-directory"; const client = new GitClient(gitDirectory);
const params = ["--output=/tmp/r2d2"]; for await (const tag of client.getTags(params)) { console.log(tag); } }
main();
- Observe new file created on disk at
/tmp/r2d2
