The Child Processes Module We can easily spin a child process using Node’s child_process module and those child processes can easily communicate with each other with a messaging system. The child_process module enables us to access Operating System functionalities by running any system command inside a, well, child process. We can control that child process input stream, and listen to its output..

Setting Up An Express Server To get started working with a Node.js project you will need to run npm init -y. This will create a basic package.json file with all of the default values filled in for you. From there the next thing to do is install Express by running npm i express. Lastly, we need to create a server.js file with the following code. const express = require('express') const app = expr..

Jest worker encountered 4 child process exceptions, exceeding retry limit If you see this kind of message in your Console, it means that it has to be done with Async and await. In my case.. describe('InputSchema when validated', () => { it('should be a valid schema', async () => { expect(Joi.isSchema(InputSchema)).toBe(true) InputSchema.validateAsync(mockValidInput) InputSchema.validateAsync(moc..

ValidationError: "action" is required If you see this kind of error when you typed it('should be a valid schema', async () => { await InputSchema.validateAsync({}) }) like this, it's because you typed your object in the { } this bracket.
