1. React JS
React JS is an open-source technology that was initially introduced as a JS library by Facebook engineers. It presents innovative ways to depict web pages with their many advantages including high performance and a dynamic UI. In React, we can reuse the components of the code, which helps us in saving time and effort and this feature comes especially handy when we have system updates. React components are distinct, thus they do not interfere with each other.
We have several features to React. Data binding is done in the downwards direction to empower a steady code. We have a virtual DOM which enables us to increase the speed. Continuous developments and enhancements by React JS community help in bringing it to the top.
Express JS is a web framework that helps designers in building web pages and websites, by using the technology Node JS. Express JS provides us with strong tools that can be used for HTTP servers, making it stable.
Express JS can be used for routing. It includes great test coverage and has features like caching and redirection, which can help with the HTTP servers. It generally executes applications and websites pretty quickly and supports numerous engines.
We use Express JS because it is very simple to build APIs in Express, making it easy to create websites and single-page applications.
3. Angular JS
Angular is a cross-platform solution, which has become popular for creating web applications, especially single-page applications. It is included in the standard and popular MEAN stack. It provides us with command-line tools and allows splitting the code, automatically. It also offers us two-way data binding, which makes our data more secure. Angular JS is continuously being upgraded and this helps it to be up-to-date on technology changes.
Nowadays, Electron has been gaining great attention as a proficient tool to create desktop applications that are cross-platform. Electron is established on Node JS and Chromium engine, extending support to the complete package consisting of HTML, CSS, and JS. Applications like Docker and desktop GitHub are created on Electron.
Electron is an open-source tool and is freely obtainable. It is compatible with Windows, Linux, and Mac systems. Electron contains demo APIs that are pre-built for applications and has Chromium tools that help in debugging. Electron also has the capability to perform unit tests within its environment. The demerit of this tool is that as it is bundled with Chromium, the sizes of updates are very huge.
NPM can work with default tasks i.e. tasks like simple tests and other such regular issues, and with arbitrary tasks i.e. tasks that we create. This tool is more preferable over Gulp or other such task-specific tools, because it provides many more packages and plugins, and also because it has lesser compatibility and debugging problems. NPM creates strong scripts, which are suitable for cross-platform projects.
Webpack has great features which include the ability to split the code into numerous pieces so that we can lessen the loading time. It also optimizes the size, by monitoring the pieces being loaded at all times. It provides us with bundling these pieces to load them either alone or along with a few parts. We can also resolve dependencies while we compile.
ESLint is also a task-specific tool that is used specifically for the task of detecting errors. It supervises the code to spot our slips, like missing a closing parenthesis or adding extra parenthesis at the end of our code. The act of examining the code for possible errors is known as ‘linting’.
