Vite is a fast and lightweight front-end building tool that allows developers to develop front-end more efficiently. Compared with other build tools, Vite is characterized by functions such as fast cold start, module hot replacement, and on-demand compilation. Below we will explore in detail the advantages of Vite and how to use it.
What is Vite
Vite is a Rollup-based build tool mainly used to build web applications and libraries. It uses ES Modules as the module system, Webpack's plug-in mechanism, and Browserify's require syntax, allowing developers to easily use modern front-end technologies, such as Vue, React, and TypeScript.
Advantages of Vite
fast cold start
Vite adopts the server-side rendering method, and does not need to pre-compile and package all JS files like other build tools. This means that whenever you modify the code, Vite will only rebuild the modified part of the code instead of rebuilding the entire application. Therefore, Vite's cold start is very fast, almost without any delay.
Module Hot Replacement
Vite supports Hot Module Replacement (HMR), which makes it very convenient to debug code during development. When you modify the code, Vite will automatically reload the module instead of refreshing the whole page. This greatly improves the development efficiency and reduces the interruption and waiting time caused by refreshing the page.
compile on demand
Vite supports on-demand compilation, which only compiles the file being modified and the currently referenced file, without compiling the entire project. This helps reduce the memory and CPU resources required at runtime, further improving the performance of the application.
How to use Vite
-
Install Node.js (if not already installed).
-
Create a new project folder and open a command line window.
-
Run the following command at the command line to initialize a new project:
npm init vite-app my-project
cd my-project
npm install
- Run the following command to start the development server:
npm run dev
-
http://localhost:3000Access the application through a browser . -
After modifying the code, save the file and Vite will automatically recompile and update the application in the browser.
Summarize
Vite is a fast and lightweight front-end construction tool, which improves the efficiency and performance of front-end development through functions such as server-side rendering, module hot replacement, and on-demand compilation. Building modern web applications and libraries is easy with Vite.
