With the availability of several tools and in the digital transformation era, every process has evolved. Then why not improve? We used to create projects with manual efforts of creating folders and transferring files using FTP.
Now developers have access to amazing tools and technologies to improve their development experiences, such as Babel and Webpack. But, to get along with changing business demands, we have to explore more new tools to deliver the best.
This brings our notice to a blazing-fast front-end development environment introduced in 2020. Since then it has gained much popularity and become the fastest tool for a seamless web development experience. Its features-rich CLI has made it easier for scaffolding projects.
But among the different options available in the market, why must developers choose Vite? What makes it more powerful and fast?
As we embark on this journey, we’ll delve into the realm of Vite and discover why it deserves our undivided attention. Let’s ensure we stay in sync with the ever-changing times and embrace this exciting new tool. So, without further ado, let’s dive into the world of Vite!
Did you know that the word “Vite” comes from the French language and it means “quickly” or “fast”? Pronounced as “Vit,” this word perfectly captures the essence of what Evan You had in mind while working on Vue3, the popular JavaScript framework.
Vite is a revolutionary development environment for Vue.js, created by none other than Evan You himself. Its purpose is to make web development as fast as possible, pushing the boundaries of what we thought was achievable. Although still in the experimental phase, the community is actively working towards refining Vite, making it suitable for production environments.
What makes Vite so special is that it eliminates the need for a traditional bundler. Instead, it serves your code through native ES Module imports during development. This means that you can effortlessly work on Vue.js single file components without the hassle of bundling them together. However, Vite cleverly utilizes Rollup for efficient bundling when it comes to a production build.
With Vite, the possibilities for web development become endless. It empowers developers to focus on what truly matters—creating amazing experiences—without being hindered by time-consuming bundling processes. Evan You’s innovative creation is reshaping the way we approach Vue.js development, and the web development community is eagerly embracing this groundbreaking tool.
But do you wonder how it does it?
I guess without highlighting what crucial web development problems result in the development of this amazing front-end tool. Right! So what was the actual problem that developers have been facing before Vite?
The Problem
Before developers could leverage the ES modules within the browsers, there were no specific methods to author the JavaScript in a modular way. This is how the term “bundling” was introduced which uses the relevant tools to crawl, process, and connect different source modules within a single file to be run in the browser.
If you are getting me, then you must know about the tools, such as webpack, Rollup, and Parcel. These tools are popularly known for their performance to improve the efficiency of developers in developing the front end.
It is obvious that developers try to create more complex applications or apps get complicated with time, resulting in increased usage of JavaScript. If any JavaScript app scales, it will contain more modules that create performance nuances for JavaScript-based tools.
It results in a long wait time to sign up into the related dev server, Hot Module Replacement, and to create/edit files in the browser. This slow speed was impacting the developer’s productivity.
This is why developers need fast and extremely reliable front-end tooling.
Vite successfully addresses all these speed-related issues. All thanks to the availability of native ES modules in the browser, and the rise of JavaScript tools written in compile-to-native languages.
Whenever you try to cold-start your dev server, your entire app will be crawled and built by a bundler-based build setup before serving it to the browser.
Vite is capable of improving and fastening the dev server start time. But how?
It divides the app modules into two categories- dependencies and source code.

Editing files in a bundler-based build setup can be inefficient because rebuilding the entire bundle takes time, and the update speed slows down as the app size increases. Some bundlers use in-memory bundling during development, which means they only need to update a portion of the module graph when a file changes. However, they still have to reconstruct the entire bundle and reload the web page, which can be expensive and resets the application’s current state.
To address these limitations, bundlers offer Hot Module Replacement (HMR), allowing modules to be replaced without affecting the rest of the page. While HMR improves the developer experience (DX), it also suffers from decreasing update speeds as the application size grows.
Vite takes a different approach by using native ESM for HMR. When a file is edited, Vite only needs to invalidate the chain between the modified module and its closest HMR boundary, usually just the module itself. This ensures consistently fast HMR updates, regardless of your application’s size.
Additionally, Vite leverages HTTP headers to accelerate full-page reloads. It offloads work to the browser by making source code module requests conditional using “304 Not Modified” responses, and dependency module requests are efficiently cached with “Cache-Control: max-age=31536000, immutable” to avoid unnecessary server hits.
After experiencing the speed of Vite, it’s unlikely that you’ll be willing to tolerate bundled development again. So, let’s take a look at what features are being offered by mighty “Vite”.
Below are the features that are the core behind the fast working of Vite.
Vite leverages cutting-edge browser technology and native ES modules to compile your code instantly, resulting in speedy builds and immediate updates within the browser.

Additionally, Vite’s built-in development server is optimized for quick reloading and hot module replacement, enabling developers to witness real-time changes to their code without refreshing the entire page. Get ready for a seamless and efficient development experience with Vite!
Vite uses lazy loading for modules, loading code only when needed. This reduces bundle sizes and boosts performance, especially for bigger apps. It also speeds up initial load times by loading non-critical code on demand.
Vite optimizes code size and performance by tree-shaking and code splitting. Tree-shaking removes unused code, while code splitting divides code into smaller, on-demand chunks. Users download only necessary code, leading to faster load times and improved performance.
Vite has a built-in development server designed for fast reloading and hot module replacement. It simplifies application development and testing by enabling real-time code changes without refreshing the entire page. The server also supports automatic code reloading for rapid iteration.
The latest version of Vite 4.0 was introduced last year with a huge ecosystem.

While Vite offers numerous advantages, it’s crucial to contemplate its drawbacks before opting for it. Here are the key disadvantages of Vite.
Due to its recent development, Vite has a smaller user community compared to established tools like Create React App or Webpack, making support and problem-solving challenging to find.
Vite, where we harness the full potential of modern JavaScript features. These innovative functionalities, however, are still on the rise and not universally supported by all browsers just yet. Thus, it’s important to note that while most users will enjoy a seamless experience with your application, a small portion might need to update their browser or utilize a clever polyfill to unlock its full glory.
When considering Vite and Create React App (CRA), it’s valuable to draw comparisons between the two, as they do share certain similarities. Interestingly, one of the primary motivations that drive developers towards Vite is their desire to break free from the confines of CRA.
Create React App, a widely embraced frontend tool, is renowned for its ability to construct web applications utilizing the powerful React JavaScript library. It presents an exceptionally smooth and efficient pathway for commencing React development, furnishing developers with a user-friendly command-line interface for effortlessly creating and managing projects. Moreover, it boasts a development server that facilitates live reloading, making the development process all the more seamless and dynamic.
Today, many companies are thinking of migrating their apps from Create React App to Vite due to the above benefits.
Moving an existing React project to Vote can be a complex process. To avoid confusion, I’ll break down the steps. Start by deleting the node_modules folder to configure the package.json file for Vite.
In case you are working with typescript, add a typescript entry point.
For small projects, the above step works fine, but in the case of big projects, you need to follow the following steps also.
Below is the .env file.
npm i vite-plugin-env-compatible or yarn add vite-plugin-env-compatible.
Then add the following code to vite.config.js or vite.config.ts file.
To enable TypeScript path aliases in Vite, install “vite-tsconfig-paths” and add it to your Vite config.
It allows Global to work anywhere within the project.
To begin, navigate to your src folder and modify the vite-env.d.ts file by adding the following line: /// <reference types=”vite-plugin-svgr/client” /> (Remember to include the ///). Following this, the import {ReactComponent as logo} from ‘your-svg-path’ will function correctly.
This is the procedure for transitioning your existing project to Vite. Although it may require some time and exploration, once you have made the switch, you will significantly reduce the duration of your development server runs and file builds for the production server.
You will be amazed to see the performance difference.
