@dudousxd/nestjs-telescope-typeorm

TypeORM query watcher for @dudousxd/nestjs-telescope. Tees every executed SQL statement into the telescope recorder, correlated to the active request batch.

How it works

TypeORM lets you supply a custom Logger at DataSource construction. This package ships TelescopeTypeOrmLogger (a Logger implementation) whose logQuery records each statement. Because the logger runs in the query's async context, queries correlate to the active request batch via ALS — exactly like the MikroORM adapter.

Usage

The host wires the logger into the DataSource:

import { DataSource } from 'typeorm';
import { telescopeTypeOrmLogger } from '@dudousxd/nestjs-telescope-typeorm';

const dataSource = new DataSource({
  // ...your connection options...
  logging: true, // or ['query'] — required so TypeORM calls logQuery
  logger: telescopeTypeOrmLogger((input) => telescopeService.record(input)),
});

logging: true (or ['query']) must be enabled, otherwise TypeORM never calls logQuery and nothing is recorded.

Durations

TypeORM's logQuery does not provide an execution time, so normal queries are recorded with durationMs: null. Slow queries are surfaced separately by TypeORM via logQuerySlow(time, ...) (gated by maxQueryExecutionTime); those are recorded with a real durationMs and a slow tag.

telescopeTypeOrmLogger((input) => telescopeService.record(input), { slowMs: 1000 });
