> Reference template: [antfu/starter-ts](https://github.com/antfu/starter-ts). When scaffolding a new TypeScript project, mirror its `package.json` scripts, `eslint.config.js`, `knip.json`, `tsdown.config.ts` and workflows rather than inventing a new layout.

## Coding Practices

### Code Organization

- **Single responsibility**: Each source file should have a clear, focused scope/purpose
- **Split large files**: Break files when they become large or handle too many concerns
- **Type separation**: Always separate types and interfaces into `types.ts` or `types/*.ts`
- **Constants extraction**: Move constants to a dedicated `constants.ts` file

### Runtime Environment

- **Prefer isomorphic code**: Write runtime-agnostic code that works in Node, browser, and workers whenever possible
