Here we draw a roadmap for you which will help you to learn the basics of Nodejs along with a comprehensive list of the best resources that will help you get up and running with Nodejs.
As a beginner, everyone tends to face some problems when they step into new technology. At first, you may feel stumbled with some confusion that crosses your mind before getting into it. In this blog, we tried to address all your questions like What is Nodejs? How to start?? Where to start?.
BASICS OF NODEJS: A ROADMAP TO LEARN
We have listed an overview topic that covers the basics of Nodejs roadmap:
- About Nodejs
- History and releases
- Nodejs architecture
- Stalling Nodejs
- NPM (Node Package Manager)
- JSON File
- Nodejs Basics
- File System
- HTTP Modules
Nodejs is so powerful that supports to build a wide range of applications such as live-streaming application, REST API, server-based web application, a real-time communication application, etc.
However, Nodejs comprises numerous concepts that help in building multi-user network applications, web servers, similar to PHP, ASP.NET.
HISTORY AND RELEASES
Nodejs was initially implemented in the year 2009 by Ryan Dahl. Within a short span of time(i.e. 10 years), Nodejs has grabbed an irreplaceable position in the web application development sector.
In 2009 Nodejs released in the market with its first-ever version of package manager called Node Package Manager(NPM) and still releasing their updated versions (From Nodejs 1.0 to Node.12) in a regular time interval. The latest version of Nodejs is node.13.0.1 released in 2019 and still continues.
Nodejs uses Single-threaded Even-Loop Model Architecture, that allows all the client request in Nodejs are executed by a single-thread operation. It is not just as single-threaded but event-driven nature as well helps the Nodejs application to handle multiple client requests concurrently.
Moving to the next step from learning Nodejs, Installing this platform can be done with a simple procedure. To download the latest and stable version of Nodejs, just visit the official Nodejs site. But before you install, make sure that your machine has enough storage space and minimum RAM of 4 GB.
NPM(NODE PACKAGE MANAGER)
Once you are done with the installation procedure, the next step is to learn about NPM- Node Package Manager acts as the core of any Nodejs application that comes 750000+ bundle of packages.
These libraries of great tools that help every developer in Nodejs application development. This NPM is essential in speeding up the application development process.
JSON File is an integral part of the Nodejs application development. Before start working on a Nodejs project, all you need is to create JSON as the first file. It is the manifest file that holds the metadata of the project.
These files are used along with the scripts for managing the dependencies used in the projects. Mostly JSON files of your Nodejs project required for generating builds and running tests.
This is a crucial step in Nodejs installation that allows us to read and write data into a file rather than on a console. Nodejs uses an fs module to access the physical file system from a directory.
Nodejs is most popular for its event-driven applications. Each Nodejs application is based on a single-threaded and perfect event-driven architecture that supports concurrency. You need an event module to create and handle custom events.
HTTP’s modules are a key functionality in Nodejs which is highly used for developing server-based applications. With Nodejs, you can create an effective REST API using the HTTP module.
Creating a Nodejs application from scratch by writing code for each and every function is a time-consuming process. To avoid such scenarios, Nodejs provides, a number of frameworks which will help you in the faster building of web application with rich features. Here, the few of the popular Nodejs frameworks:
As of now, you will know basic ideas to develop a whole functional Nodejs application. Running an application requires large storage of data in a database.
Nodejs avails you to choose any database based on your application requirement. Here we list some best-fit databases that greatly support Nodejs applications.
We hope that this “Basics of Nodejs: A complete roadmap to learn” blog helps you to learn the basics of Nodejs web development.
