NPM
$ npm i -s nestjs-airgramYarn
$ yarn add nestjs-airgramOnce the installation process is complete, now we need TDLib 1.7 binaries, how to get them you need to build them by this guide, or you can found here,
then place binaries somewhere in your project workspace. Then we can import the module TdlModule either synchronously or asynchronosly into the root AppModule.
It is important to specify the correct path to the TDLib binaries in the command field.
It is directly passed to dlopen / LoadLibrary. Check your OS documentation to see where it searches for the library.
import { Module } from '@nestjs/common';
import { AirgramModule } from 'nestjs-airgram';
@Module({
imports: [
AirgramModule.forRoot({
apiId: 'YOUR_APP_ID',
apiHash: 'YOUR_API_HASH',
command: path.resolve('tdjson.dll'), // Path to tdlib
auth: {
// ...
},
}),
],
})
export class AppModule {}Then we can inject Airgram into our services. And use decorators for events.
import { Injectable, OnModuleInit } from '@nestjs/common';
import {
Airgram,
Context,
GetMeMiddleware,
UpdateNewMessageMiddleware,
} from 'airgram';
import {
ExtractMiddlewareContext,
InjectAirgram,
OnEvent,
OnRequest,
OnUpdate,
} from 'nestjs-airgram';
@Injectable()
export class AppService implements OnModuleInit {
constructor(@InjectAirgram() private airgram: Airgram) {
setTimeout(() => this.onModuleInit(), 4000);
}
async onModuleInit(): Promise<void> {
const me = await this.airgram.api.getMe();
console.log('[Me]', me);
}
@OnEvent()
onAnyEvent(ctx: Context): void {
// This code will be invoked before every request and after all updates.
}
@OnUpdate()
async onUpdate(update: unknown): Promise<void> {
// This code will be invoked after update.
}
@OnRequest()
async onRequest(): Promise<void> {
// This code will be invoked before request.
}
@OnEvent('getMe')
onGetMe(ctx: ExtractMiddlewareContext<GetMeMiddleware>): void {
console.log('"GetMe" request triggered', ctx);
// This code will be invoked before "Get me" request.
}
@OnEvent('updateNewMessage')
onNewMessage(
ctx: ExtractMiddlewareContext<UpdateNewMessageMiddleware>,
): void {
console.log('"NewMessage" update triggered', ctx);
// This code will be invoked after "New message" update.
}
