Since Vite’s release, front-end developers may be especially delighted and contented. Well, we’re part of the front-end community. Without Vite, the fastest front-end development possibilities would not have been conceivable. 

Vite has experienced a great deal of development over the last two years, and Vite 4 introduces some new and enhanced capabilities. 

Describe Vite.

Vite itself translates to “quick.” It is a front-end build tool and development server that offers a quick, easy, and lightweight development environment. It facilitates the integration of multiple JavaScript frameworks and libraries, including Vue, React, Preact, and Svelte, and serves your code while it is being developed, bundles your files for production, and supports.

Vite has experienced a great deal of development over the last two years, and Vite 4 introduces several new and enhanced capabilities. Additional command line shortcuts are among them (press h in Vite 4 to see a list of all the shortcuts). For more ES2020 compatibility, the software supports Safari 14. It also supports patch-package when pre-bundling dependencies and has enhanced error messages during SSR.

In Vite 4, the next four enhancements are quite significant.

1. Rollup 3 

Developers can combine various JavaScript modules into a single file using Rollup, a JavaScript module bundler. As a result, the application runs more quickly because fewer requests are necessary for the browser to load the code.

Rollup 3 is currently used by Vite while building. Rollup 2 was utilized by Vite version 3, however, when Rollup 3 was released in October 2022, the new version of Vite included a significant update to Rollup 3.

Even though Rollup 3 is generally compatible with Rollup 2, you should consult the Rollup migration guide before upgrading.

2. Environment variables

Dotenv and dotenv-expand requirements were modified in Vite. Dotenv 16 and Dotenv-expand 9 are the current versions in use. To ensure appropriate operation with this update, you must enclose values that contain the characters “#” or “‘” in quotes.

Vite suggests using the dotenv command line interface to make modifying ENV files easier.

This optional plugin can aid in ensuring that ENV files are consistent among various devices, settings, or team members. It might make the arduous process of changing ENV files easier.

3.  New React Plugin with the use of Speedy Web Compiler (SWC)

SWC has been added to Vite v4 as a substitute or alternative for Babel, which was utilized in Vite v3 and is notably useful for React projects.

Rust-based SWC is a lightning-fast JavaScript compiler. SWC and Babel are JavaScript compilers that change your code so that browsers can read it; SWC asserts that it is quicker than Babel.

Vite 4 adds two plugins (vitejs/plugin-react and vitejs/plugin-react-swc) with various compromises for React projects while still supporting Babel.

The vitejs/plugin-react Plugin

By utilizing rebuild and Babel, this plugin allows quick Hot Module Replacement with a small package size. While Hot Module Replacement allows for a fat refresh, it also provides the added flexibility of being able to leverage the Babel transform pipeline.

Without having to reload the entire page, it enables developers to update modules in an application that is already running. 

The Plugin for vitejs/plugin-react-swc

This is a new plugin that uses Speed Web Compiler for development and esbuild for building.

The plugin attempts to considerably accelerate development, especially for applications that don’t require non-standard React extensions, by switching from Babel to SWC.

4. Importing CSS as a String

Vite is more than simply a build tool; it also includes innovative features that let you work with CSS features like URL re-bashing and CSS splitting.

However, regardless of the setups, you can choose to use such functions. By taking into account aliases and npm dependencies, Vite’s resolver enhances the @import and URL () paths in CSS.

5. Experimental Server-side Rendering Support

Vite SSR assists you by providing a fantastic tooling experience for a higher-level feature shortly with its low-level features. And when it comes to the production build, SSR is independent of the build tool.

This construction tool also provides APIs and constructs for efficiently loading and changing ESM-based source code. The responsibility for automatically externalizing CommonJS-compatible dependencies is its final and most crucial duty. 

Currently, Vite supports server-side rendering (SSR). Typically, SSR for React.js technology and Vue version 3 are supported by Vite 2.0.

Other Vite 4 Advantages

Vite 4’s features do not stop there. There’s more to it.

Other Vite 4 characteristics include:

• patch-package support for multiline values in env files update @types/node to v18.
• Along with several enhancements, bug fixes, and optimizations.

Therefore, the time has come to join Vite, the front-end development tool with the fastest performance. You can find everything on Vite 4’s GitHub site if you want to use its most recent features.  Or, you can hire Vite developers from Atlas SoftWeb for a seamless development experience.
