`@idebug/nest` (NestJS)

Nest integration on the same core store and UI as Express.

Install

pnpm add @idebug/nest @nestjs/common @nestjs/core @nestjs/platform-express
pnpm --filter @idebug/ui build

Module setup

import { Module } from '@nestjs/common';
import { IDebugModule } from '@idebug/nest';
import { AppController } from './app.controller';
import { AppService } from './app.service';
 
@Module({
  imports: [
    IDebugModule.forRoot({
      enabled: true,
      appName: 'my-nest-api',
      performance: true,
      db: true,
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

IDebugModule.register is an alias of forRoot.

`@Loggable()`

import { Injectable } from '@nestjs/common';
import { Loggable } from '@idebug/nest';
 
@Injectable()
export class CalcService {
  @Loggable()
  add(a: number, b: number) {
    return a + b;
  }
 
  @Loggable()
  divide(a: number, b: number) {
    if (b === 0) throw new Error('Division by zero is not allowed');
    return a / b;
  }
}

Emits functionCall enter and exit into the shared store (uses module config from forRoot, not a fresh config instance).

What gets registered

Global middleware	ALS + req/res + UI at `basePath`
`PerformanceInterceptor`	Handler-level enter/exit timings when `performance: true`
`IDebugService`	Programmatic `logFunctionIO`
`ModuleLogger`	Wrap plain modules
