How to Setup for Node.js with Visual Studio Code

Node.js is a platform for building fast and scalable server applications using JavaScript. Node.js is the runtime and npm is the Package Manager for Node.js modules. In this post, we will Setup for Node.js with Visual Studio Code

Introduction

Node.js is a platform for building fast and scalable server applications using JavaScript. Node.js is the runtime and npm is the Package Manager for Node.js modules. Visual Studio Code has support for the JavaScript and TypeScript languages out-of-the-box as well as Node.js debugging. However, to run a Node.js application, you will need to install the Node.js runtime on your machine.

Let's get started by creating the simplest Node.js Express application, "Let's Start with Node.js".

Why Node.js?

  • Node.js is free.
  • Node.js  Platform independent
  • Node.js Uses asynchronous programming.

Download the Node.js source code or a pre-built installer for your platform._https://nodejs.org/en/download/_Create an empty folder called "MyFirstProject" or any name as you wish.

Open Command Prompt-> Go To MyFirstProject by command cd like

D:\Workspace\Clients\dev-parveen\node_projects>cd MyFirstProject

Then follow the npm command as,

D:\Workspace\Clients\dev-parveen\node_projects\MyFirstProject>npm init
D:\Workspace\Clients\dev-parveen\node_projects\MyFirstProject>npm init ->Press Enter

npm init can be used to set up a new or existing npm package or you can simply Google exactly what they do.

After pressing enter key it will ask for package name and other setup details as follows:

package name: (myfirstproject) pkgnode ("pkgnode" is a name of package given by me or you can give it as you wish). => Press enter key to continue

version: (1.0.0) 1.0.0 (Set project version as you wish). => Press enter to continue

description: This is my first node project. => Press enter to continue

entry point: (index.js) app.js ("app.js" is a name of start-up file or you can give it as you wish). => Press enter to continue

test command: it is optional or or can specify test command, the command that is run whenever you call npm test. => Press enter key to continue.

git repository: git repo / it is optional =>press enter key to continue.

keywords: optional => Press enter =>Press enter key to continue.

author: Parveen =>(Optional) Press enter key to continue.

license: (ISC) =>(Optional), default set ISC, Press enter key to continue.

After completion of npm init step, package.json file is added to your project, you can check in your project directory display as:

Here I am using VSCode editor; open your project in it.

In VSCode, add a Java script file namely app.js and write code,

This is image title

We are going to create express application using Node.js. Let’s install the express to your project. So now let’s open VSCode PowerShell command terminal:

Go To Menu bar => Terminal => New Terminal

Now install the express using npm: npm –i express ↵

It will install the express module to your project and you can check package.json file in your project and can see express package detail.

Now write the following code sample to your app.js file,

const express = require('express');  
const app = express();  
const port = 3000;  
app.get('/', (req, res) => res.send('Welcome To Nodejs!'));  
app.listen(3000, () => console.log(`Example app listening on port ${port}!`));   

Now run the Node.js app using NPM start or node app.js in terminal

You have successfully created your first Node app. Don’t stop here, keep exploring the wonderful world of Node.js, as it has much more to offer.

This app starts a server and listens on port 3000 for connections. The app responds with “Let's Start with Node.js” for requests to the root URL (/) or route. For every other path, it will respond with a 404 Not Found.

Why does the world need another package manager / what’s wrong with npm? JavaScript is an exemplar of a larger problem: code reuse via artifacts with dependency metadata delivered by a registry that controls namespaces and versioning

Why does the world need another package manager / what’s wrong with npm? JavaScript is an exemplar of a larger problem: code reuse via artifacts with dependency metadata delivered by a registry that controls namespaces and versioning. Registries are poised to provide functionality for communities: security assurances, static analysis, invariants around version availability, user support. JS is special because it has the largest registry and the most code reuse in the wild, but other communities need this too.

Docker. Rust. Ruby. Python. This is a problem that communities keep solving and re-solving. There hasn’t been a satisfactory answer to the problem of funding. Money is ultimately what supports these gossamer webs of packages. Without money, that web disintegrates. At JavaScript’s scale, the money it takes to support the web is enormous. Further, there’s value in expanding this web, and that means more language communities will contribute to this web over time, making it yet more expensive to support. We could give this web to a company with deep pockets, but we’re placing a lot of trust in an entity that’s not entirely incentivized to keep our best interests at heart.

So, the question is: how do we make this web of packages less expensive as it gets bigger? How do we preserve community control of that web? How do we earn the trust of other language communities, so we can solve the problem of artifact dependencies once and reap the benefits across all languages? We think Entropic is the answer: federated registries and distributed trust recast this ephemeral web of packages in diamond, adamant and self-supporting.

Top 7 Most Popular Node.js Frameworks You Should Know

Top 7 Most Popular Node.js Frameworks You Should Know

Node.js is an open-source, cross-platform, runtime environment that allows developers to run JavaScript outside of a browser. In this post, you'll see top 7 of the most popular Node frameworks at this point in time (ranked from high to low by GitHub stars).

Node.js is an open-source, cross-platform, runtime environment that allows developers to run JavaScript outside of a browser.

One of the main advantages of Node is that it enables developers to use JavaScript on both the front-end and the back-end of an application. This not only makes the source code of any app cleaner and more consistent, but it significantly speeds up app development too, as developers only need to use one language.

Node is fast, scalable, and easy to get started with. Its default package manager is npm, which means it also sports the largest ecosystem of open-source libraries. Node is used by companies such as NASA, Uber, Netflix, and Walmart.

But Node doesn't come alone. It comes with a plethora of frameworks. A Node framework can be pictured as the external scaffolding that you can build your app in. These frameworks are built on top of Node and extend the technology's functionality, mostly by making apps easier to prototype and develop, while also making them faster and more scalable.

Below are 7of the most popular Node frameworks at this point in time (ranked from high to low by GitHub stars).

Express

With over 43,000 GitHub stars, Express is the most popular Node framework. It brands itself as a fast, unopinionated, and minimalist framework. Express acts as middleware: it helps set up and configure routes to send and receive requests between the front-end and the database of an app.

Express provides lightweight, powerful tools for HTTP servers. It's a great framework for single-page apps, websites, hybrids, or public HTTP APIs. It supports over fourteen different template engines, so developers aren't forced into any specific ORM.

Meteor

Meteor is a full-stack JavaScript platform. It allows developers to build real-time web apps, i.e. apps where code changes are pushed to all browsers and devices in real-time. Additionally, servers send data over the wire, instead of HTML. The client renders the data.

The project has over 41,000 GitHub stars and is built to power large projects. Meteor is used by companies such as Mazda, Honeywell, Qualcomm, and IKEA. It has excellent documentation and a strong community behind it.

Koa

Koa is built by the same team that built Express. It uses ES6 methods that allow developers to work without callbacks. Developers also have more control over error-handling. Koa has no middleware within its core, which means that developers have more control over configuration, but which means that traditional Node middleware (e.g. req, res, next) won't work with Koa.

Koa already has over 26,000 GitHub stars. The Express developers built Koa because they wanted a lighter framework that was more expressive and more robust than Express. You can find out more about the differences between Koa and Express here.

Sails

Sails is a real-time, MVC framework for Node that's built on Express. It supports auto-generated REST APIs and comes with an easy WebSocket integration.

The project has over 20,000 stars on GitHub and is compatible with almost all databases (MySQL, MongoDB, PostgreSQL, Redis). It's also compatible with most front-end technologies (Angular, iOS, Android, React, and even Windows Phone).

Nest

Nest has over 15,000 GitHub stars. It uses progressive JavaScript and is built with TypeScript, which means it comes with strong typing. It combines elements of object-oriented programming, functional programming, and functional reactive programming.

Nest is packaged in such a way it serves as a complete development kit for writing enterprise-level apps. The framework uses Express, but is compatible with a wide range of other libraries.

LoopBack

LoopBack is a framework that allows developers to quickly create REST APIs. It has an easy-to-use CLI wizard and allows developers to create models either on their schema or dynamically. It also has a built-in API explorer.

LoopBack has over 12,000 GitHub stars and is used by companies such as GoDaddy, Symantec, and the Bank of America. It's compatible with many REST services and a wide variety of databases (MongoDB, Oracle, MySQL, PostgreSQL).

Hapi

Similar to Express, hapi serves data by intermediating between server-side and client-side. As such, it's can serve as a substitute for Express. Hapi allows developers to focus on writing reusable app logic in a modular and prescriptive fashion.

The project has over 11,000 GitHub stars. It has built-in support for input validation, caching, authentication, and more. Hapi was originally developed to handle all of Walmart's mobile traffic during Black Friday.
