 使用示例

const GitTools = require('./lib/gitTools.js');

// 下述修改为你的本地git仓库目录
var git = new GitTools(`D:\\template\\template\\template\\template\\template`);

// 自动化上传
// await git.autoUpload('自动化上传','dev');

// 切换分支
// await git.checkout('dev');

// 拉取代码 
// await git.pull('dev');

// 暂存
// await git.add();

// 提交
// await git.commit('测试');

// 推送
// await git.push('dev');

// 是否存在修改
// var result = await git.status();
