## 开发
|
||||
|
||||
首次运行需要先安装依赖
|
||||
|
||||
```bash
|
||||
$ npm install
|
||||
```
|
||||
|
||||
一键打包生成生产代码
|
||||
|
||||
```bash
|
||||
$ npm run build
|
||||
```
|
||||
|
||||
运行单元测试，浏览器环境需要手动测试，位于`test/browser`
|
||||
|
||||
```bash
|
||||
$ npm test
|
||||
```
|
||||
|
||||
修改 package.json 中的版本号，修改 README.md 中的版本号，修改 CHANGELOG.md，然后发布新版
|
||||
|
||||
```bash
|
||||
$ npm run release
|
||||
```
|
||||
|
||||
将新版本发布到 npm
|
||||
|
||||
```bash
|
||||
$ npm publish
|
||||
```
