I wanted to build my own Telegram app using this great library. However, I quickly noticed that the project was quite outdated, so I decided to upgrade all dependencies to their latest versions, remove unused ones, migrate the project to 100% ESM, and fix several existing issues (for example, a typo in .prettierrc where the i was missing).
So here's what were upgraded:
18.2.0->19.2.318.2.0->19.2.318.2.0→19.2.8^18→19.2.3@xelene/vaul-with-scroll-fixwith official[email protected]. This might require to be checked, but the original package is depricated due to burnout of the developer.7.6.17→10.1.11. Deprecated packages were removed or migrated to the new ones.@storybook/react-vite.8.x→9.39.2.eslintrc.jstoeslint.config.mjs(flat config)8.52.04.0.165.9.33.7.4(reformatted 273 files)2.1.68.0.29.2.1, cross-env10.1.0As I said before, the focus of this upgrade was to move the project to the latest technologies, so I haven't touched components much. Only lint-related issues and configs.
FAQ
Why have you removed Jest and moved to Vitest?
Vitest is faster, supports native ESM, and has native support with Typescript. It uses the same API as Jest, so migration was straightforward. Test execution improved from ~400ms to 166ms. And I want to keep simplicity.
Why have you changed Webpack to Vite for storybook?
Vite provides a significantly better developer experience. Storybook startup is 6-8x faster, HMR is 20-30x faster. Vite is the modern standard for React development and officially supported by Storybook 10. Plus, we removed a lot of plugins that were needed for Webpack.
Why are many dependencies missing?‼️ . Dependencies dropped 46% (492M → 264M) while maintaining identical bundle sizes.
Vite effectively replaced the entire Webpack/Babel ecosystem. We removed 18 packages (webpack, babel-loader, and other various plugins) and gained the same functionality with better performance
So what do we have in the end? I have done some direct comparisons and here are the results:
