5. Set up Different Really useful Modules
Contemplate putting in further modules for frequent duties, equivalent to atmosphere variables and logging:
| Module | Function |
|---|---|
| dotenv | Manages atmosphere variables |
| winston | Logging |
| pretty-ms | Codecs time intervals |
You may set up these modules with:
npm set up dotenv winston pretty-ms
Initializing a Typescript Mission
To provoke a TypeScript venture for Discord.js, you may have to create a brand new listing and initialize a brand new npm package deal inside it. Set up the mandatory dependencies utilizing npm or Yarn, then create a brand new TypeScript configuration file and add the suitable compiler choices.
Making a New Mission
Begin by creating a brand new listing on your venture:
“`bash
mkdir my-discordjs-project
cd my-discordjs-project
“`
Subsequent, initialize a brand new npm package deal inside the listing:
“`bash
npm init -y
“`

“`json
{
“compilerOptions”: {
“goal”: “es5”,
“module”: “commonjs”,
“outDir”: “./dist”,
“sourceMap”: true,
“noImplicitAny”: true,
“strictNullChecks”: true
},
“embody”: [
“./src”
],
“exclude”: [
“node_modules”
]
}
“`
These choices make sure that your TypeScript code is compiled to ES5-compliant JavaScript, bundled right into a dist listing, and type-checked to forestall 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, you might want to log in utilizing your bot token. Use the next code to log in:
“`typescript
consumer.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 consumer is logged in, you may deal with occasions. To deal with an occasion, create a listener perform and go it to the on() technique. 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 shall be known as. The message object incorporates details about the message, equivalent 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 hear 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. Here is how one can deal with occasions in Discord.js with TypeScript:
1. Create an Occasion Listener
To create an occasion listener, you may want to make use of the on() technique of the Consumer class. The on() technique takes two arguments: the occasion title and a perform that shall be executed when the occasion happens.
2. Outline the Occasion Handler Perform
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 offers 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 incorporates the message that was despatched.
4. Deal with A number of Occasions with a Single Listener
You may deal with a number of occasions with a single listener by passing an array of occasion names to the on() technique.
5. Take away Occasion Listeners
To take away an occasion listener, use the off() technique of the Consumer class. The off() technique takes two arguments: the occasion title and the perform that was beforehand registered as an occasion handler.
6. Take heed to As soon as for an Occasion
In the event you solely have to hearken to an occasion as soon as, you should use the as soon as() technique. The as soon as() technique works identical to the on() technique, besides that the occasion listener shall be mechanically 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 |
