Repository

Usage

import { Repository } from '@napi-rs/simple-git'

Repository.init('/path/to/repo') // init a git repository

const repo = new Repository('/path/to/repo') // Open an existed repo

const timestamp = new Date(repo.getFileLatestModifiedDate('build.rs')) // get the latest modified timestamp of a `build.rs`
console.log(timestamp) // 2022-03-13T12:47:47.920Z

const timestampFromAsync = new Date(await repo.getFileLatestModifiedDateAsync('build.rs')) // Async version of `getFileLatestModifiedDate`

console.log(timestamp) // 2022-03-13T12:47:47.920Z

API

export class Repository {
  static init(p: string): Repository

Reference

Usage

import { Repository } from '@napi-rs/simple-git'

const repo = new Repository('/path/to/repo') // Open an existed repo

const headReference = repo.head()

headReference.shorthand() // 'main'
headReference.name() // 'refs/heads/main'
headReference.target() // 7a1256e2f847f395219980bc06c6dadf0148f18d

Performance

Compared with the exec function, which gets the file's latest modified date by spawning a child process. Getting the latest modified date from the file 1000 times:

Child process took 1.9s
@napi-rs/simple-git took 65ms
