Why is Vite fast? The default choice for modern front-end build tools

vitejs/vite is a very common build tool in modern front-end projects. Its description is very short: Next generation frontend tooling. It’s fast! This sentence basically summarizes the core selling points of Vite: fast development startup, fast hot update, and relatively light configuration.

If you have created a new Vue, React, Svelte, Solid or ordinary TypeScript front-end project in the past few years, you have probably used Vite.

Why Vite is fast

Vite’s speed mainly comes from two stages of trade-offs:

Development stage: Use the browser’s native ESM to avoid packaging the entire project at the beginning;
Production stage: Use Rollup for optimized construction;
Dependency pre-building: use faster tools to process dependencies;
HMR: Module-level hot update, where the changes are made, they will be refreshed.

Traditional bundlers tend to be slow to start and hot update when the project becomes larger. Vite takes the development experience one step closer to “on-demand loading”.

Which projects are suitable for

Vite is suitable for:

Vue / React / Svelte / Solid projects;
TypeScript front-end application;
Component library development;
Static site and tool pages;
Small and medium-sized Web App;
Teams that need fast startup and fast HMR.

It can also be used for large projects, but be aware of monorepo, SSR, plugin compatibility, build cache and legacy browser support.

What should you pay attention to when using it?

The default experience of Vite is very good, but it does not require any configuration:

Environment variable prefixes and injection rules need to be understood;
The dev server agent must be configured clearly;
alias, path, and tsconfig must be aligned;
Please read separate documents for SSR and library mode;
The plug-in version and the framework version must match;
Production builds still depend on package size and subcontracting.

Don’t misunderstand “development is fast” as “production builds don’t bother”. Performance, caching and compatibility still need to be looked at before going online.

Summary

Vite has become one of the default options for modern frontends. It’s popular not because the concepts are complex, but because the day-to-day development experience is truly breezy.

If you are still using very old scaffolding, you can try Vite first for new projects; when migrating old projects, you must first evaluate plug-ins, build processes, and team habits.
