Before you bury yourself in packages, learn the Node.js runtime itself. This article will challenge the very limits of your Node.js knowledge.
I started learning Node.js shortly after Ryan Dahl first presented it, and I wasn’t able to answer a lot of the questions I ask in this article even a year ago. If you can truly answer all of these questions, then your knowledge of Node.js is beyond great. We should be friends. The reason I think this challenge will take you by surprise is that many of us have been mostly learning Node the wrong way. Most tutorials, books, and courses about Node focus on the Node ecosystem — not the Node runtime itself. What is Node.js? - Quora. What is a good Node js workflow, editor tools & framework? - Quora.

What is a Node JS Server?
Node JS gives the front-end developer (and back-end developers) the ability to use JavaScript (JS) as the back-end server-side scripting language instead of other back-end server-side languages. This is exceptionally useful for front-end JS developers looking to do server-side scripting as well. When you develop an application using Node, the application you write is the server. Node.js Basics - bl.ocks.org. HTTP module Basic HTTP Server: Issues: Difficulty in handling routesDifficulty in serving static filesno template engine support Similar thing in PHP (But only for development): php -S localhost:8000 ExpressJS Features.
Untitled. Node.js Express Framework. Express Overview Express is a minimal and flexible Node.js web application framework that provides a robust set of features to develop web and mobile applications.
It facilitates the rapid development of Node based Web applications. Following are some of the core features of Express framework − Allows to set up middlewares to respond to HTTP Requests.Defines a routing table which is used to perform different actions based on HTTP Method and URL.Allows to dynamically render HTML Pages based on passing arguments to templates. Installing Express Firstly, install the Express framework globally using NPM so that it can be used to create a web application using node terminal. $ npm install express --save The above command saves the installation locally in the node_modules directory and creates a directory express inside node_modules. . $ npm install body-parser --save $ npm install cookie-parser --save $ npm install multer --save Hello world Example.

Naturally v0.12 was followed by v4.0. What happened here?! Io.js happened, and with it, Node got semantic versioning (semver). io.js First some history: in 2015, a group of Node.js developers & core platform engineers were eager to start using the latest and greatest Node and V8 features, and unwilling to wait for them to be land in the joyent/node “master” release channel. Along with the project merger came the organization of the official Node.js Foundation to serve the community. Semver. Creating a basic site with Node.js and Express.

Some of these objects aren't actually in the global scope but in the module scope - this will be noted. The objects listed here are specific to Node.js. There are a number of built-in objects that are part of the JavaScript language itself, which are also globally accessible. Class: Buffer# RunKit is Node prototyping.

Node.js debugging with Chrome DevTools (in parallel with browser JavaScript)
Recently Paul Irish described how you can debug Node.js applications with Chrome DevTools.
Since that time Chrome DevTools have evolved and the step, where you had to open the separate page with a specific URL to debug the Node.js code, was removed. It means, today you can debug your browser JavaScript files and Node.js ones in the same DevTools window in parallel, which makes the perfect sense. Let’s take a look how it works. Javascript (and Node.js) Continues To Eat The World – Presence Press – Medium. After spending two days at NodeSummit 2016 a few weeks ago, there’s no doubt in my mind that Javascript, and Node in particular, is eating the world.
Case Studies From The Conference NodeSummit offered several case studies that were demonstrative of the power that Node provides to some of the world’s largest enterprises and organizations. In three months from today, 98% of all Walmart.com traffic will be serviced via Node APIs and displayed with React.js according to Alex Grigoryan, Director of Software Engineering at WalMart Labs. Three months after that, SamsClub.com, Walmart’s second biggest property, will be 100% javascript based. Even their iOS and Android experiences will eventually be done in React Native, a javascript technology that’s made to replace native Java/Objective C coding. With this switch, Walmart has managed to significantly reduce their time to market while enabling their entire development team to understand, and develop for, their entire stack. Substack/browserify-handbook. Browserify. Require('modules') in the browser Use a node-style require() to organize your browser code and load modules installed by npm. browserify will recursively analyze all the require() calls in your app in order to build a bundle you can serve up to the browser in a single <script> tag.
If you're new to browserify, check out the browserify handbook and the resources on browserify.org. Tape. Tap-producing test harness for node and browsers $ node example/timing.js TAP version 13 # timing test ok 1 should be equal not ok 2 should be equal operator: equal expected: 100. Npm. Modules Node.js v6.3.1 Manual & Documentation. Understanding module.exports and exports in Node.js. As developers, we often face situations where we need to use unfamiliar code. A question will arise during these moments. How much time should I invest in understanding the code that I’m about to use? A typical answer is learn enough to start coding; then explore that topic further when time permits.
Node-inspector/node-inspector. Debugger Node.js v6.3.0 Manual & Documentation. Stability: 2 - Stable Node.js includes an out-of-process debugging utility accessible via a TCP-based protocol and built-in debugging client. To use it, start Node.js with the debug argument followed by the path to the script to debug; a prompt will be displayed indicating successful launch of the debugger: $ node debug myscript.js < debugger listening on port 5858 connecting... ok break in /home/indutny/Code/git/indutny/myscript.js:1 1 x = 5; 2 setTimeout(() => { 3 debugger; debug> Node.js's debugger client is not a full-featured debugger, but simple step and inspection are possible. Inserting the statement debugger; into the source code of a script will enable a breakpoint at that position in the code: x = 5;setTimeout(() => { debugger; console.log('world');}, 1000); console.log('hello'); Once the debugger is run, a breakpoint will occur at line 4: The repl command allows code to be evaluated remotely.
Pressing enter without typing a command will repeat the previous debugger command. Nodemon.
