Installation

Node.js 16.6.0 or newer is required.

npm

$ npm install @globalart/nestcord discord.js

Yarn

$ yarn add @globalart/nestcord discord.js

pnpm

$ pnpm add @globalart/nestcord discord.js

Usage

Once the installation process is complete, we can import the NestCordModule into the root AppModule:

src/app.module.ts

import { NestCordModule } from '@globalart/nestcord';
import { Module } from '@nestjs/common';
import { IntentsBitField } from 'discord.js';
import { AppUpdate } from './app.update';

@Module({
    imports: [
        NestCordModule.forRoot({
            token: 'DISCORD_BOT_TOKEN',
            intents: [IntentsBitField.Flags.Guilds]
        })
    ],
    providers: [AppUpdate]
})
export class AppModule {}

Then create app.update.ts file and add On/Once decorators for handling Discord API events:

src/app.update.ts

import { Injectable, Logger } from '@nestjs/common';
import { Context, On, Once, ContextOf } from '@globalart/nestcord';
import { Client } from 'discord.js';

@Injectable()
export class AppUpdate {
    private readonly logger = new Logger(AppUpdate.name);

    public constructor(private readonly client: Client) {}

    @Once('ready')
    public onReady(@Context() [client]: ContextOf<'ready'>) {
        this.logger.log(`Bot logged in as ${client.user.username}`);
    }

    @On('warn')
    public onWarn(@Context() [message]: ContextOf<'warn'>) {
        this.logger.warn(message);
    }
}

Whenever you need to handle any event data, use the Context decorator.
