What should you pay attention to when making a Discord bot?

Error handling when developing Discord bots is just as crucial as it is when building an API service. You should use **try-except blocks** and **logging mechanisms** to manage errors effectively. For instance, you can catch API error responses (like 429 Too Many Requests or 401 Unauthorized) and either send a message to the user or temporarily pause the bot. Additionally, it's important to respect Discord API's rate limits—exceeding them could lead to temporary bans, similar to encountering CAPTCHA blocks in web scraping projects. To keep the bot running continuously, you should implement **continuous monitoring** and **auto-restart mechanisms**. For example, you can run the bot in a **Docker container** with **Restart Policies** set to always restart. Alternatively, you can use a process manager like **PM2** to automatically restart the bot if it crashes, just like in Node.js projects. When it comes to libraries, **discord.py** or **nextcord** (a fork of discord.py) are stable and widely used options—**disnake** is also a great alternative in terms of performance and features.

When developing a Discord bot with Python, the most important thing to keep in mind is understanding Discord API limitations and scenarios where your bot needs to run continuously. First and foremost, pay serious attention to "rate limiting" when using the Discord API. Especially when using async versions of libraries like `discord.py`, you should space out API calls using methods like `asyncio.sleep()`. Otherwise, you risk your bot being permanently banned by Discord. For error handling, you should frequently use try-except blocks. It's critical to catch specific exceptions like `discord.Forbidden` and `discord.HTTPException` that may arise while parsing API responses to prevent your bot from crashing. Additionally, to keep your bot running continuously, the most stable solution is to monitor it with tools like supervisor (PM2, systemd) and automatically restart it when necessary. For example, with systemd, you can configure `Restart=always` in a configuration like `/etc/systemd/system/discord_bot.service`. For library selection, `discord.py` (especially the async version) and `nextcord` (a fork of discord.py, recommended due to its more active development process) are the most stable options. Since older versions of `discord.py` may cause issues in the future, you might also consider `nextcord`, which is continuously updated. If you're familiar with JavaScript, `discord.js` is also a very mature alternative. Lastly, never share your bot token in public spaces like GitHub and minimize security risks by managing it with `.env` files!
