It will lists all the files that will be included in the package IF we were to update it. The “--dry-run” flag doesn’t actually publish anything. It lists all the files that would be published. npm publish --dry-run

There are a few areas that may provide benefits: It is easier to build and use interfaces at a suitable level for a use case, rather than being forced into low-level details for pretty much everything with CloudFormation. Better default tooling. AWS CDK has a command-line tool that makes it rather easy to deploy, update, check for changes and delete Cloud infrastructure stacks. The default tooli..

What exactly are streams? Streams are collections of data — just like arrays or strings. The difference is that streams might not be available all at once, and they don’t have to fit in memory. This makes streams really powerful when working with large amounts of data, or data that’s coming from an external source one chunk at a time. However, streams are not only about working with big data. Th..

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..

Why not just specify the port as 3000 instead of typing sixteen characters? What it is The process.env global variable is injected by the Node at runtime for your application to use and it represents the state of the system environment your applica..
