Default to using Bun instead of Node.js.

• Use bun <file> instead of node <file> or ts-node <file>
• Use bun test instead of jest or vitest
• Use bun build <file.html|file.ts|file.css> instead of webpack or esbuild
• Use bun install instead of npm install or yarn install or pnpm install
• Use bun run <script> instead of npm run <script> or yarn run <script> or pnpm run <script>
• Use bunx <package> <command> instead of npx <package> <command>
• Bun automatically loads .env, so don't use dotenv.

APIs

• Bun.serve() supports WebSockets, HTTPS, and routes. Don't use express.
• bun:sqlite for SQLite. Don't use better-sqlite3.
• Bun.redis for Redis. Don't use ioredis.
• Bun.sql for Postgres. Don't use pg or postgres.js.
• WebSocket is built-in. Don't use ws.
• Prefer Bun.file over node:fs's readFile/writeFile
• Bun.$ls instead of execa.

Testing

Use bun test to run tests.

import { test, expect } from "bun:test";

test("hello world", () => {
  expect(1).toBe(1);
});

Coding Style & Naming Conventions

TypeScript (strict). Runtimes: Bun 1.3+, Node 23. Prettier: 2 spaces, no semicolons, double quotes, width 100. Import order: @ianvs/prettier-plugin-sort-imports + Tailwind plugin. ESLint (flat): any disallowed; unused vars warned (prefix _ to ignore). Naming: React components PascalCase; files kebab-case (e.g., user-profile.ts); packages @repo/. Comments: avoid writing inline comments everywhere, unless absolutely necessary for a todo or an important thing to take note of. Instead write tsdoc style block level comments at the method/class/function/route level. Focus on comments that provide value in regards to better type inference and clarity of usage. Using things like params/returns/etc..

Always default to useing named paramaters in functions eg myFunction({ ctx, other }) vs myFunction(ctx, other) Never use any types and always default to leveraging generics and smart types to sensure the best possible tpye inference across the project.
