npm-run

Run executables in node_modules from the command-line

Use npm-run to ensure you're using the same version of a package on the command-line and in package.json scripts.

Any executable available to an npm lifecycle script is available to npm-run.

Usage

> npm install mocha # mocha installed in ./node_modules
> npm-run mocha test/* # uses locally installed mocha executable

> npm-run --help
Usage: npm-run command [...args]
Options:
  --version  Display version & exit.
  --help     Display this help & exit.

Hint: to print augmented path use:
npm-run node -p process.env.PATH

Installation

> npm install -g npm-run

Programmatic API

The API of npm-run basically wraps core child_process methods (exec, spawn, etc) such that locally install package executables will be on the PATH when the command runs.

npmRun(command[, options], callback)

Alias of npmRun.exec.

npmRun.exec(command[, options], callback)

Takes same arguments as node's exec.

npmRun.exec('mocha --debug-brk --sort', {cwd: __dirname + '/tests'}, function (err, stdout, stderr) {
  // err Error or null if there was no error
  // stdout Buffer|String
  // stderr Buffer|String
})

npmRun.sync(command[, options])

Alias of npmRun.execSync

npmRun.execSync(command[, options])

Takes same arguments as node's execSync.

var stdout = npmRun.execSync(
  'mocha --debug-brk --sort',
  {cwd: __dirname + '/tests'}
)
stdout // command output as Buffer|String

npmRun.spawnSync(command[, args][, options])

Takes same arguments as node's spawnSync.

var child = npmRun.spawnSync(
  'mocha',
  '--debug-brk --sort'.split(' '),
  {cwd: __dirname + '/tests'}
)
child.stdout // stdout Buffer|String
child.stderr // stderr Buffer|String
child.status // exit code

npmRun.spawn(command[, args][, options])

Takes same arguments as node's spawn.

var child = npmRun.spawn(
  'mocha',
  '--debug-brk --sort'.split(' '),
  {cwd: __dirname + '/tests'}
)
child.stdout // stdout Stream
child.stderr // stderr Stream
child.on('exit', function (code) {
  code // exit code
})

Why

Due to npm's install algorithm node_modules/.bin is not guaranteed to contain your executable. npm-run uses the same mechanism npm uses to locate the correct executable.

npm 包管理器run命令使用

npm run命令需和项目根目录下的package.json文件配合使用； npm run执行package.json文件的“scripts”属性中定义的命令，如下例： { "name": "my-project", "version": "1.0.0", "description": "A Vue.js project", "author": "zhouguoqing <

在本文中，苏南大叔描述的就是npm run的潜规则：pre和post。而且在查看本文的内容前，您一定要知晓:npm run命令都是定义在package.json文件的scripts节点里面的。测试环境：mac，npm@6.14.3。 { "name": "nnn", "version": "1.0.0", "description": "", "main": "index.js",
