node.JS is considered by many web developers to be the ideal environment to run in. node.JS is designed to run in jAscript, one of the world's most popular programming languages, which allows a wide community of developers to build server-side applications. node.JS provides the ability to reuse through the JASCRIPT library, but choosing the right one can be difficult. Useful libraries can reduce development time and provide several advantages for your web application, such as faster load times and smaller application package sizes. When choosing a library, you need to consider factors such as the complexity of the application, the community that supports the library, the frequency of updates, and the quality of the documentation. node.The JS library is available via NodeThe JS package manager npm, which helps to install various open source libraries. Immediately following from the previous part, we will continue to share 5 important nodesJS libraries, they make web development simpler.
Lodash is a j**ascript utility that helps developers write simple and easy-to-maintain files. It includes more than 200 useful functions for common programming tasks, such as type checking, simple math operations, and more.
Features and benefits of the Lodash library
Use polyfills for cross-browser compatibility.
Built-in solutions are provided for working with arrays of objects, such as filter, search, and flatmap.
Help developers avoid redundancies and maintain clarity.
Axios is a promise-based nodeJS and browser HTTP client. It also manages the browser or nodeTransformation of JS request and response data. axios is isomorphic, which means it can use the same library on both the server and the client. AXIOS uses the native HTTP module on the server side and XMLhttpRequest for HTTP communication on the client side.
Features and benefits of the axios library
API methods for common HTTP data types such as Get, Put, Post, and Delete are provided.
Improve security by preventing cross-site request forgery (CSRF) when performing HTTP queries over the Internet.
Automate JSON data translation and easily convert response data into JSON format.
puppeteer is a nodeThe JS framework, which provides a high-level API via the DevTools protocol, allows you to automate the browser by controlling Chrome Chromium. It can be used to automate front-end testing, such as testing to process requests, identifying and comparing UI components, and performance testing. It is possible to build a Chromium instance by importing the puppeteer package into their**, which can then communicate with the browser engine for automated testing.
Advantages and features of the puppeteer library:
No setup required, simple configuration, and no additional drivers are required.
* Crawled to generate pre-rendered content.
Compatible with well-known testing frameworks such as JEST and Mocha.
Multer is a Node. built on top of the HTML form parser BusboyJS middleware library that supports multi-part and multi-form data. After initializing the multer instance, one of the parameters is a test object that specifies where the uploaded file will be saved on the server. Multer passes the upload request to a file object, which is parsed by the Multer API and transmitted to the target site.
Features & Benefits of the Multer Library:
With built-in parsing, raw HTTP request data is more easily available for storage.
Allows you to define the encoding type of the file, providing an additional degree of protection for the uploaded file.
You can filter and limit the upload choices for file types and sizes.
Dotenv is a nodeJS utility module for managing environment variables and protecting critical configuration data for applications. Dotenv also helps applications save environment variables according to the twelve-factor application method. When the dotenv library is configured early in the application, from:.envThe environment variables of the file are immediately injected into the processenv.
Features and benefits of the Dotenv library
Allows secret information (such as API keys and login credentials) to be decoupled from the source** and allows each developer to establish their own.envFile.
Since it is a zero-dependency module, it does not increase the size of the program.
on nodeThere are many useful libraries in JS, but choosing the ideal one for your project can be a little difficult. Some nodeThe JS library may become a "must-have tool" in your future application.
