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
	});

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";
