“`bash
# Utilizing npm
npm set up discord.js typescript @sorts/node
# Utilizing Yarn
yarn add discord.js typescript @sorts/node
“`
The @sorts/node bundle gives sort definitions for Node.js, that are important for utilizing TypeScript with Discord.js.
Creating the TypeScript Configuration File
Create a brand new file named tsconfig.json in your venture listing. This file will comprise the configuration on your TypeScript compiler. Add the next choices to the file:
“`json
{
“compilerOptions”: {
“goal”: “es5”,
“module”: “commonjs”,
“outDir”: “./dist”,
“sourceMap”: true,
“noImplicitAny”: true,
“strictNullChecks”: true
},
“embody”: [
“./src”
],
“exclude”: [
“node_modules”
]
}
“`
These choices be sure that your TypeScript code is compiled to ES5-compliant JavaScript, bundled right into a dist listing, and type-checked to stop errors.
Connecting to the Discord API
To hook up with the Discord API, you have to to acquire a bot token from the Discord Developer Portal. After getting a token, you need to use the discord.js library to create a brand new shopper and hook up with the API.
Making a New Shopper
To create a brand new shopper, use the next code:
“`typescript
const { Shopper, Intents } = require(‘discord.js’);
const shopper = new Shopper({
intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES]
});
“`
The intents array specifies which occasions the shopper will pay attention for. On this instance, the shopper will pay attention for GUILDS and GUILD_MESSAGES occasions.
Logging In
After getting created a shopper, you want to log in utilizing your bot token. Use the next code to log in:
“`typescript
shopper.login(course of.env.BOT_TOKEN);
“`
Exchange course of.env.BOT_TOKEN together with your precise bot token.
Dealing with Occasions
As soon as the shopper is logged in, you possibly can deal with occasions. To deal with an occasion, create a listener perform and cross it to the on() methodology. For instance, the next code listens for the message occasion:
“`typescript
shopper.on(‘message’, message => {
console.log(`Message acquired: ${message.content material}`);
});
“`
When a message is acquired, the message occasion listener will likely be known as. The message object incorporates details about the message, similar to its content material and the channel it was despatched in.
Dealing with Occasions with Typescript
If you’re a JavaScript developer, chances are you’ll be acquainted with occasion listeners, which let you pay attention for particular occasions and execute code after they happen.
In Discord.js, occasion dealing with is just like JavaScript, however makes use of a special syntax. This is how one can deal with occasions in Discord.js with TypeScript:
1. Create an Occasion Listener
To create an occasion listener, you will want to make use of the on() methodology of the Shopper class. The on() methodology takes two arguments: the occasion title and a perform that will likely be executed when the occasion happens.
2. Outline the Occasion Handler Operate
The occasion handler perform is a daily TypeScript perform that receives an occasion object as an argument. The occasion object incorporates details about the occasion that occurred.
3. Use the Occasion Object
The occasion object gives entry to varied properties and strategies that you need to use to get details about the occasion. For instance, the message property of a messageCreate occasion object incorporates the message that was despatched.
4. Deal with A number of Occasions with a Single Listener
You’ll be able to deal with a number of occasions with a single listener by passing an array of occasion names to the on() methodology.
5. Take away Occasion Listeners
To take away an occasion listener, use the off() methodology of the Shopper class. The off() methodology takes two arguments: the occasion title and the perform that was beforehand registered as an occasion handler.
6. Hearken to As soon as for an Occasion
If you happen to solely have to take heed to an occasion as soon as, you need to use the as soon as() methodology. The as soon as() methodology works similar to the on() methodology, besides that the occasion listener will likely be robotically eliminated after it’s executed.
7. Use Occasion Namespaces
| Occasion Namespace | Description |
|---|---|
shopper |
Occasions that happen inside the shopper |
guild |
Occasions that happen inside a guild |
channel |
Occasions that happen inside a channel |
message |
Occasions that happen associated to messages |
response |
Occasions that happen associated to reactions |
person |
Occasions that happen associated to customers |
voice |
Occasions that happen associated to voice channels |
