About this version
This library regroups some utilities that is used accross nestjs packages
You can find a LoggerModule that export a LoggerService. This module use
the Logger token from @nestjs/common to let you access directly from your DI
at the nestjs logging system. Under the hood the LoggerService extends the Logger
of nestjs and format correctly your messages.
import { LoggerModule } from '@tractr/nestjs-common';
import { MyService } from './my-service.service';
@Module({
imports: [LoggerModule],
providers: [MyService],
})
export class MyApp {}import { Injectable, Logger } from '@nestjs/common';
@Injectable()
export class MyService {
constructor(private readonly logger: Logger) {}
helloWorld() {
this.logger.log('Hello World');
}
}If you need to access to more functionality of the LoggerService like the
setContext or setMetadata you will need to tell to typescript what interface
is used under the hood by the Logger token.
import { Inject, Injectable, Logger } from '@nestjs/common';
@Injectable()
export class MyService {
constructor(@Inject(Logger) private readonly logger: LoggerService) {
this.setContext(MyService.name);
this.setMetadata({ foo: 'bar' })
}
helloWorld() {
this.logger.log('Hello World');
// Updating the context
this.logger.log('Hello World', 'One time override context');
// Updating the context and add more metadata
this.logger.log('Hello World', { bar: 'foo' }, 'One time override context');
// Override the metadata
this.logger.log('Hello World', { foo: 'foo' });
}
}This logger is intended to work with the winston logger to be able to output
correctly into the console in development and in an ecs format in production.
@see @tractr/nestjs-winston library for more information.
