JSPM – p-spawn@0.5.3

Package Exports

p-spawn

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (p-spawn) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Yet another spawn promise. (Zero dependency!)

Promisified child_process.spawn, with more options
stdout/stderr to console by default.
Route stdout or stderr to file.
Can run spawn as detached (promise will return with handle)
Typescript definitions

Notes:

Require node.js > 8.0 (if you need more support, log ticket)
Warning: From 0.4.0 needs to be imported as { spawn }

import { spawn } from 'p-spawn'
// or `const {spawn } from 'p-spawn'

await spawn(cmd, args, opts); // return Promise

Examples:

const { spawn } = require("p-spawn");


async function test(){
  // will console log the stdout and stderr
  await spawn("echo", ["hello world"]);


  // will not console log the stdout but rather to forward in onStdout
  var txt = [];
  await spawn("echo", ["hello world"], {
    onStdout: (data) => {
      txt.push(data.toString());
    }
  });
  console.log(txt.join("\n"));

  // we an pass spawn options as well
  await spawn("pwd", {
    cwd: "./test",
    onStdout: (data) => {
      txt.push(data.toString());
    }
  });

  // we an pass spawn options as well
  var result = await spawn("echo",["hello world"], {capture: "stdout"});

  console.log(result.stdout); // "hello world"  
}
