name: Create a Discord bot
---
Discord.js works out of the box with Bun. Let's write a simple bot. First create a directory and initialize it with `bun init`.
```bash
mkdir my-bot
cd my-bot
bun init
```
---
Now install Discord.js.
```bash
bun add discord.js
```
---
Before we go further, we need to go to the [Discord developer portal](https://discord.com/developers/applications), login/signup, create a new _Application_, then create a new _Bot_ within that application. Follow the [official guide](https://discordjs.guide/preparations/setting-up-a-bot-application.html#creating-your-bot) for step-by-step instructions.
---
Once complete, you'll be presented with your bot's _private key_. Let's add this to a file called `.env.local`. Bun automatically reads this file and loads it into `process.env`.
{% callout %}
This is an example token that has already been invalidated.
{% /callout %}
```txt#.env.local
DISCORD_TOKEN=NzkyNzE1NDU0MTk2MDg4ODQy.X-hvzA.Ovy4MCQywSkoMRRclStW4xAYK7I
```
---
Be sure to add `.env.local` to your `.gitignore`! It is dangerous to check your bot's private key into version control.
```txt#.gitignore
node_modules
.env.local
```
---
Now let's actually write our bot in a new file called `bot.ts`.
```ts#bot.ts
// import discord.js
import {Client, Events, GatewayIntentBits} from 'discord.js';
// create a new Client instance
const client = new Client({intents: [GatewayIntentBits.Guilds]});
// listen for the client to be ready
client.once(Events.ClientReady, (c) => {
console.log(`Ready! Logged in as ${c.user.tag}`);
});
// login with the token from .env.local
client.login(process.env.DISCORD_TOKEN);
```
---
Now we can run our bot with `bun run`. It may take a several seconds for the client to initialize the first time you run the file.
```bash
$ bun run bot.ts
Ready! Logged in as my-bot#1234
```
---
You're up and running with a bare-bones Discord.js bot! This is a basic guide to setting up your bot with Bun; we recommend the [official discord.js docs](https://discordjs.guide/) for complete information on the `discord.js` API.
