🧰️ @acme/vite

This package contains presets and utils used to configure Vite for app and library development.

Installation

pnpm install @acme/vite @vitejs/plugin-react vite-plugin-dts

Presets

Library

Can be used to set up development of vanilla JS or React libraries. It uses @vitejs/plugin-react and vite-plugin-dts to generate TypeScript definition files.

Preset does the following things for you:

  • It externalises dependencies and native node imports using rollup-plugin-node-externals. Your libraries should not have React or react-dom in their bundles (unless you have a good reason for it).
  • React, react-dom, and jsx-runtime imports are globalised under React, ReactDOM and react/jsx-runtime objects/imports.
  • vite-plugin-dts is used to generate TypeScript definition files for your library. We are also rolling up types with rollupTypes to produce a single dts file. You can safely add dist or vite config to your includes in tsconfig, preset will ignore them during build.
  • While outputting types, we are ignoring vite config and test files, so you can include them in your tsconfigs safely.
  • If dts diagnostics fail, we will throw an error and stop the build process.

Options All options come from the plugins that are used in the preset. You can pass them as an object to the preset and they will be merged accordingly.

import { type PluginOptions as DtsOptions } from 'vite-plugin-dts';
import { type Options as ReactOptions } from '@vitejs/plugin-react';
import { type ExternalsOptions } from 'rollup-plugin-node-externals';

interface LibraryPresetOptions {
  externals?: ExternalsOptions;
  react?: ReactOptions;
  dts?: DtsOptions;
}

Tldr; Should you use this preset?

  • If you want to build publishable browser/react library, use the library preset.
  • If you want to just transpile your code, use tsc (possibly in watch mode)

Vite bundles your code in library mode as if it was something that will be consumed by a browser. It has a separate --ssr mode for server usages. Bundling is complicated, and if you don't care about inlining dependencies, tree shaking, and other optimisations, because for example you are creating a node library, don't use any heavy tool for that, you don't need it.
