If just need a query builder, it is recommended to just use

const options = {
  dropMigrator: true,
  dropSchema: true,
  minifyMethodName: true,
}

Example

Build with tsup and setup plugin.esbuild()

See in example/

import { Kysely, sql } from 'kysely'
import { EmptyDialect } from 'kysely-wasm'

const db = new Kysely<{ test: { test: number } }>({
  dialect: new EmptyDialect(),
})

export function test(): Promise<unknown> {
  return sql`select 1`.execute(db)
}

console.log(db.insertInto('test').values({ test: 1 }).compile().sql)

Build Result

Trim 57.73% at most
