Here's my attempt to do write it in async/await way (which actually works): async function callToolsAsync(req) { let pipshell = 'pipenv'; let args = ['run', 'tools']; req. Those processes can easily communicate with each other using a built-in messaging system. There are four different ways to create a child process in Node: spawn(), fork(), exec(), and execFile(). js. Node js has the native async await using util. stdout) { return data } } The child_process. push(arg) }); let tool = spawn(pipshell, args); for await (const data of tool. child; try { let { . spawn as an async function that returns a promise. promisify in their documentation but it did not work for me for the same reason (not emitting close and exit events). A cross-platform version of Node's child_process. Here's my attempt to do write it in async/await way (which actually works): async function callToolsAsync(req) { let pipshell = 'pipenv'; let args = ['run', 'tools']; req. A simple way to wait the end of a process in nodejs is : const child = require('child_process'). spawn-async. exec); const { stdout, stderr } = await exec('ls');. exec('python celulas. promisify(require('node:child_process').
