child_process
Nodejs 子进程使用案例
## child_process
### 执行 `yarn install`
```js
const { spawnSync } = require('child_process');
spawnSync("yarn install",{
shell: true,
stdio: 'inherit'
});
```
### 获取 `git config` 信息
#### spawnSync
- [How to read child_process.spawnSync stdout with stdio option 'inherit'](https://stackoverflow.com/questions/35689080/how-to-read-child-process-spawnsync-stdout-with-stdio-option-inherit)
```js
const { spawnSync } = require('child_process');
const gitConfig = spawnSync("git config --get user.name", {
stdio: 'pipe',
encoding: 'utf-8',
shell: true,
})
console.log(gitConfig.stdout.trim());
```
#### execSync
- [vue-cli git-user.js](https://unpkg.com/browse/[email protected]/lib/git-user.js)
```js
const { execSync } = require('child_process');
console.log(gitConfig.stdout.trim());
const name = execSync('git config --get user.name')
console.log(name.toString().trim());
```
## execa
### 执行 `yarn install`
> 一个[小问题](https://github.com/sindresorhus/execa/issues/473)坑我很久。
```js
const execa = require("execa");
execa.commandSync('yarn install',{
stdout: "inherit",
stderr: "inherit",
shell: true,
});
```
### 获取 `git config` 信息
```js
const execa = require("execa");
const {stdout: username} = execa.commandSync('git config --get user.name');
console.log(username);
```
## exec-sh
### 执行 `yarn install`
```js
const execSh = require('exec-sh').promise;
(async () => {
await execSh('yarn install',{
shell: true
})
})()
```
## shelljs
### 执行 `yarn install`
> 这是唯一一个不能满足需求的库，但是这个库的核心功能其实是封装了很多 shell 方法，但是也有点脱裤子放屁，我直接用 execa 也可以直接执行任何命令呀。
```js
const shell = require("shelljs");
shell.exec("yarn install");
```
