concurrent-run ·

Simple, zero dependency, multiple commands runner in concurrent mode.

Installation

npm

npm install --save-dev concurrent-run

Yarn

yarn add --dev concurrent-run

Usage

CLI

concurrent-run "command1 arg" "command2 arg"

API

import { ConcurrentRun, Command } from "concurrent-run";
 
const concurrent = new ConcurrentRun();
 
concurrent
    .run(["command1 arg", "command2 arg"])
    .on("data", (data: Buffer, command: Command) => {
        // data from spawned process stderr and stdout
    })
    .on("close", (exitCode: number, command: Command) => {
        // after command is finished
    })
    .on("error", (err: Error, command: Command) => {
        // after an error occurs
    });

Events

• data gets called once stderr or stdout of spawned process sends data.

import { ConcurrentRun, Command } from "concurrent-run";
 
const concurrent = new ConcurrentRun();
 
concurrent
    .run(["command1 arg"])
    .on("data", (data: Buffer, command: Command) => {
        // do something...
    });

• close gets called once command is finished.

import { ConcurrentRun, Command } from "concurrent-run";
 
const concurrent = new ConcurrentRun();
 
concurrent
    .run(["command1 arg"])
    .on("close", (exitCode: number, command: Command) => {
        // do something...
    });

• error gets called once an error occurs.

import { ConcurrentRun, Command } from "concurrent-run";
 
const concurrent = new ConcurrentRun();
 
concurrent
    .run(["command1 arg"])
    .on("error", (err: Error, command: Command) => {
