How to get logging on terminalthe raw query in prisma, nestjs?
I am setting up for logging using prisma and nestjs.
in my code:
PrismaModule.forRoot({
isGlobal: true,
prismaServiceOptions: {
prismaOptions: { log: ['info', 'query']},
explicitConnect: true,
},
}),
this is logging middleware
import { Prisma } from '#prisma/client';
export function loggingMiddleware(): Prisma.Middleware {
return async (params, next) => {
const before = Date.now();
const result = await next(params);
const after = Date.now();
console.log(
`Query ${params.model}.${params.action} took ${after - before}ms`,
);
return result;
};
}
this is my prismaService
#Injectable()
export class PrismaService
extends PrismaClient<
Prisma.PrismaClientOptions,
'query | error | debug | info'
>
implements OnModuleInit, OnModuleDestroy {
private readonly logger = new Logger(PrismaService.name);
constructor() {
super({ log: [{ emit: 'event', level: 'query' }] });
this.logger.log(`Prisma v${Prisma.prismaVersion.client}`);
this.$on('query', (e) => this.logger.debug(`${e.query} ${e.params}`));
}
// constructor() {
// super({
// log: [
// { emit: 'event', level: 'query' },
// { emit: 'stdout', level: 'info' },
// { emit: 'stdout', level: 'warn' },
// { emit: 'stdout', level: 'error' },
// ],
// errorFormat: 'colorless',
// });
// }
async onModuleInit() {
await this.$connect();
}
async onModuleDestroy() {
await this.$disconnect();
}
async enableShutdownHooks(app: INestApplication) {
this.$on('beforeExit', async (event) => {
console.log(event.name);
await app.close();
});
}
}
I want to show raw query on terminal like TypeORM. But I can get anything on terminal.
How do I configure prisma logging correctly?

The simplest way to print all log levels to stdout is to pass in an array LogLevel objects:
const prisma = new PrismaClient({
log: ['query', 'info', 'warn', 'error'],
})
This is the short form of passing in an array of LogDefinition objects where the value of emit is always stdout:
const prisma = new PrismaClient({
log: [
{
emit: 'stdout',
level: 'query',
},
{
emit: 'stdout',
level: 'error',
},
{
emit: 'stdout',
level: 'info',
},
{
emit: 'stdout',
level: 'warn',
},
],
})
