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:

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

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"
