@node-cli/run

Node CLI run command

@node-cli/run is a dead-simple script runner for nodejs command-line applications.

Installation

> cd your-project
> npm install --save-dev @node-cli/run

Usage

import { run } from "@node-cli/run";
const { stdout, stderr } = await run("npm config ls");

API

run(command, options) ⇒ Promise <string> | Promise <object>

Runs a shell command asynchronously and returns both stdout and stderr. If the command fails to run (invalid command or the commands status is anything but 0), the call will throw an exception. The exception can be ignored if the options.ignoreError flag is true.

Arguments

Argument	Type	Default
command	String	""
options	Object	{ }
options.ignoreError	Boolean	false
options.streamOutput	Boolean	false

Note

If ignoreError is used, the method will not throw but will instead return an object with the keys exitCode and shortMessage.

Examples

Basic usage

import { run } from "@node-cli/run";
const { stdout, stderr } = await run("npm run build");

Multiple commands

import { run } from "@node-cli/run";
const { stdout, stderr } = await run(
  "git add -A && git commit -a -m 'First commit'"
);

Stream output

import { run } from "@node-cli/run";
await run("npm run build", {
  streamOutput: true
});

Ignore error

import { run } from "@node-cli/run";
const { exitCode, shortMessage } = await runCommand("ls /not-a-folder", {
  ignoreError: true
});
// -> exitCode is 1 and shortMessage is "Command failed with exit code 1: ls /not-a-folder"
