Class DummyDriver

A driver that does absolutely nothing.

You can use this to create Kysely instances solely for building queries

Examples

This example creates a Kysely instance for building postgres queries:

import {
  DummyDriver,
  Kysely,
  PostgresAdapter,
  PostgresIntrospector,
  PostgresQueryCompiler
} from 'kysely'
import type { Database } from 'type-editor' // imaginary module

const db = new Kysely<Database>({
  dialect: {
    createAdapter: () => new PostgresAdapter(),
    createDriver: () => new DummyDriver(),
    createIntrospector: (db: Kysely<any>) => new PostgresIntrospector(db),
    createQueryCompiler: () => new PostgresQueryCompiler(),
  },
})
Copy

You can use it to build a query and compile it to SQL but trying to execute the query will throw an error.

const { sql } = db.selectFrom('person').selectAll().compile()
console.log(sql) // select * from "person"
Copy
