Download

• With yarn: yarn add -D simple-nodejs-threader

Getting started

• Create a new Process manager

const manager = new ProcessManager("My task name");

• Create one or more processes that can run in parallel

const backendProcess = ProcessManager.promiseSpawn(
  "yarn start:backend",
  [processFlags],
  {
    stdio: "inherit",
    shell: true,
  }
);

const frontendProcess = ProcessManager.promiseSpawn(
  "yarn start:frontend",
  [processFlags],
  {
    stdio: "inherit",
    shell: true,
  }
);

• Add processes to the manager queue

manager.queue(frontendProcess, backendProcess);

• Await for completion

await manager.complete();
