Config
This library wraps the default @nestjs/config
library and adds the ability to define variables that are required for the service to launch and the ability to parse environment variables.
import { Module } from '@nestjs/common';
import { ConfigModule } from '@microservice-stack/nest-config';
@Module({
imports: [
ConfigModule.register({
requiredEnvironmentVariables: [
'STRING_VARIABLE',
'JSON_VARIABLE',
],
parse: (configVariable, value) => {
if (configVariable === 'JSON_VARIABLE') {
return JSON.parse(value);
}
return value;
}),
],
controllers: [],
providers: [],
})
export class AppModule {}
The ConfigModule
is registered globally, so you can inject it as you wish
import { ConfigService } from '@microservice-stack/nest-config';
export class AppService {
constructor(private configService: ConfigService) {}
public hello(): string {
return this.configService.get('STRING_VARIABLE');
}
}
