What is wait-port?

The wait-port npm package is a utility that allows you to wait for a port on a host to become open. This is particularly useful in scenarios where you need to ensure that a service is up and running before proceeding with the next steps in your application or script. It can be used programmatically within your Node.js applications or as a command-line tool.

What are wait-port's main functionalities?

Waiting for a port programmatically

This feature allows you to wait for a specific port on a host to become open by using the wait-port package programmatically within your Node.js application. The `waitPort` function returns a promise that resolves to a boolean indicating whether the port opened before the timeout.

const waitPort = require('wait-port');

const params = {
  host: 'localhost',
  port: 3000
};

waitPort(params).then((open) => {
  if(open) console.log('The port is now open!');
  else console.log('The port did not open before the timeout.');
});

Using wait-port as a CLI tool

wait-port can also be used as a command-line tool. This example demonstrates how to wait for port 3000 on localhost to become open by using wait-port in the terminal. It's useful for scripting and automation tasks outside of Node.js applications.

wait-port --host localhost --port 3000
