“`bash
# Utilizing npm
npm set up discord.js typescript @varieties/node
# Utilizing Yarn
yarn add discord.js typescript @varieties/node
“`
The @varieties/node package deal supplies 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 challenge listing. This file will include the configuration to your TypeScript compiler. Add the next choices to the file:
“`json
{
“compilerOptions”: {
“goal”: “es5”,
“module”: “commonjs”,
“outDir”: “./dist”,
“sourceMap”: true,
“noImplicitAny”: true,
“strictNullChecks”: true
},
“embrace”: [
“./src”
],
“exclude”: [
“node_modules”
]
}
“`
These choices be certain 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’ll need to acquire a bot token from the Discord Developer Portal. Upon getting a token, you should use the discord.js library to create a brand new consumer and hook up with the API.
Making a New Consumer
To create a brand new consumer, use the next code:
“`typescript
const { Consumer, Intents } = require(‘discord.js’);
const consumer = new Consumer({
intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES]
});
“`
The intents array specifies which occasions the consumer will hear for. On this instance, the consumer will hear for GUILDS and GUILD_MESSAGES occasions.
Logging In
Upon getting created a consumer, it’s essential to log in utilizing your bot token. Use the next code to log in:
“`typescript
consumer.login(course of.env.BOT_TOKEN);
“`
Substitute course of.env.BOT_TOKEN along with your precise bot token.
Dealing with Occasions
As soon as the consumer 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
consumer.on(‘message’, message => {
console.log(`Message acquired: ${message.content material}`);
});
“`
When a message is acquired, the message occasion listener will probably be referred to as. The message object accommodates details about the message, resembling its content material and the channel it was despatched in.
Dealing with Occasions with Typescript
In case you are a JavaScript developer, you could be aware of occasion listeners, which let you hear for particular occasions and execute code after they happen.
In Discord.js, occasion dealing with is much like JavaScript, however makes use of a special syntax. Here 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 Consumer class. The on() methodology takes two arguments: the occasion identify and a perform that will probably be executed when the occasion happens.
2. Outline the Occasion Handler Perform
The occasion handler perform is an everyday TypeScript perform that receives an occasion object as an argument. The occasion object accommodates details about the occasion that occurred.
3. Use the Occasion Object
The occasion object supplies entry to varied properties and strategies that you should use to get details about the occasion. For instance, the message property of a messageCreate occasion object accommodates 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 Consumer class. The off() methodology takes two arguments: the occasion identify 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 hearken to an occasion as soon as, you should use the as soon as() methodology. The as soon as() methodology works similar to the on() methodology, besides that the occasion listener will probably be routinely eliminated after it’s executed.
7. Use Occasion Namespaces
| Occasion Namespace | Description |
|---|---|
consumer |
Occasions that happen inside the consumer |
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 |
