How to add Custom prefix to your Discord Bot. Discordjs Tutorial

## <center> Hello Everyone</center>

In the previous posts, we have learned some basics of discord.js.  We created a simple discord bot that responded whenever a user messages it. It was a basic bot that helps us learn how to interact with Discord using JavaScript. If you have noticed some of the discord bots response only when a user message with a specific command like ? /! Etc. This is called the prefix. This helps us avoid messages from other users. Like if anyone needs the bot they should send a message to bot or in the specific discord channel with the particular prefix in order to get bot attention. The bot will watch all the messages and if the message start with the provided prefix it will respond. So let's start our tutorial.

* I have the code from our previous post. If you haven't read the previous post I recommend reading that post first. This script will only keep our bot online.

The second file is config.json. This only contain the bot token and prefix.

Whenever someone message to the bot/channel this function will be called.

let me just run the bot and resend the message to the user just for checking purpose.

As you can see the bot is responding.



Now we need to check bot is check whether the message is sent by the user or a bot. For that, we will check the message with if statement.

if the author is a bot then ignore it.

and only reply when the user message the word help otherwise ignore all the messages. lets re-run the code.

 As you can see the bot is ignoring all other messages even when the first letter of the word help is small.

* Now if the user message with ? (which is our prefix) then reply otherwise ignore.

![image.png](https://images.hive.blog/DQmRpJBhY21UBnyoJbs3UwixfWobFKi8bqD5GYjmBq14T6h/image.png)

Now to get the right message we need to remove the prefix from the message.
