description: Use Bun instead of Node.js, npm, pnpm, or vite.
globs: "*.ts, *.tsx, *.html, *.css, *.js, *.jsx, package.json"
alwaysApply: false
---

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>`
- 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.

```ts#index.test.ts
import { test, expect } from "bun:test";

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

## Frontend

Use HTML imports with `Bun.serve()`. Don't use `vite`. HTML imports fully support React, CSS, Tailwind.

Server:

```ts#index.ts
import index from "./index.html"

Bun.serve({
routes: {
"/": index,
"/api/users/:id": {
GET: (req) => {
return new Response(JSON.stringify({ id: req.params.id }));
},
},
},
// optional websocket support
websocket: {
open: (ws) => {
ws.send("Hello, world!");
},
message: (ws, message) => {
ws.send(message);
},
close: (ws) => {
// handle close
}
},
development: {
hmr: true,
console: true,
}
})
```

HTML files can import .tsx, .jsx or .js files directly and Bun's bundler will transpile & bundle automatically. `<link>` tags can point to stylesheets and Bun's CSS bundler will bundle.

```html#index.html
<html>
<body>
<h1>Hello, world!</h1>
<script type="module" src="./frontend.tsx"></script>
</body>
</html>
```

With the following `frontend.tsx`:

```tsx#frontend.tsx
import React from "react";

// import .css files directly and it works
import './index.css';

import { createRoot } from "react-dom/client";

const root = createRoot(document.body);

export default function Frontend() {
return <h1>Hello, world!</h1>;
}

root.render(<Frontend />);
```

Then, run index.ts

```sh
bun --hot ./index.ts
```

For more information, read the Bun API docs in `node_modules/bun-types/docs/**.md`.

Workflow does not contain permissions Medium test

Actions job or workflow does not limit the permissions of the GITHUB_TOKEN. Consider setting an explicit permissions block, using the following as a minimal starting point: {contents: read}

Copilot Autofix

AI 10 months ago

To fix the issue, we will add a permissions block to the workflow. Since the workflow only performs read operations (e.g., checking out the repository and installing dependencies), we will set contents: read as the minimal required permission. This ensures that the workflow has only the permissions it needs to function correctly.

The permissions block will be added at the root of the workflow, applying to all jobs in the workflow.

⚠️ Potential issue

Fix boundary check logic in encoding function.

The boundary check has a logical issue - it checks if asciiCodePoint > 0xE0001 but this excludes 0xE0001 itself, which should be a valid encoded character.

-    if (asciiCodePoint && asciiCodePoint > 0xE0001 && asciiCodePoint < 0xE007F) {
+    if (asciiCodePoint && asciiCodePoint >= 0xE0001 && asciiCodePoint <= 0xE007F) {
       encoded += String.fromCodePoint(asciiCodePoint);
     }

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In cli/src/audit/decodeLanguageTags.ts around lines 35 to 37, the boundary check
for asciiCodePoint incorrectly excludes the value 0xE0001 by using a strict
greater than operator. Change the condition to include 0xE0001 by using a
greater than or equal to operator (>=) instead of >, so the check becomes
asciiCodePoint >= 0xE0001 and asciiCodePoint < 0xE007F.

🛠️ Refactor suggestion

Remove test code from production.

The test code and console.log statements should not be included in production code. Consider moving this to a separate test file.
