kysely-surrealdb

Kysely dialects, plugins and other goodies for SurrealDB.

SurrealQL is based on SQL, so why not? :trollface:

Installation

NPM 7+

npm i kysely-surrealdb

NPM <7

npm i kysely-surrealdb kysely

Yarn

yarn add kysely-surrealdb kysely

PNPM

pnpm add kysely-surrealdb kysely

Deno

This package uses/extends some Kysely types and classes, which are imported using its NPM package name -- not a relative file path or CDN url.

To fix that, add an import_map.json file.

{
  "imports": {
    "kysely": "https://cdn.jsdelivr.net/npm/kysely@0.22.0/dist/esm/index.js"
  }
}

Usage

HTTP Dialect

SurrealDB's HTTP endpoints allow executing SurrealQL queries in the browser and are a great fit for serverless functions and other auto-scaling compute services.

Node.js 16.8+

Older node versions are supported as well, just swap undici with node-fetch.

import {GeneratedAlways, Kysely} from 'kysely'
import {SurrealDatabase, SurrealDbHttpDialect} from 'kysely-surrealdb'
import {fetch} from 'undici'

interface Database {
  person: {
    id: GeneratedAlways<string>
    first_name: string | null
    last_name: string | null
    age: number
  }
  pet: {
    id: GeneratedAlways<string>
    name: string
    owner_id: string | null
  }
}

const db = new Kysely<SurrealDatabase<Database>>({
  dialect: new SurrealDbHttpDialect({
    database: '<database>',
    fetch,
    hostname: '<hostname>',
    namespace: '<namespace>',
    password: '<password>',
    username: '<username>',
  }),
})

Web Socket Dialect - Soon^TM

SurrealKysely Query Builder

The awesomeness of Kysely, with some SurrealQL query builders patched in.

import {GeneratedAlways, Kysely} from 'kysely'
import {SurrealDbHttpDialect, SurrealKysely} from 'kysely-surrealdb'
import {fetch} from 'undici'

interface Database {
  person: {
    id: GeneratedAlways<string>
    first_name: string | null
    last_name: string | null
    age: number
  }
  pet: {
    id: GeneratedAlways<string>
    name: string
    owner_id: string | null
  }
}

const db = new SurrealKysely<Database>({
  dialect: new SurrealDbHttpDialect({
    database: '<database>',
    fetch,
    hostname: '<hostname>',
    namespace: '<namespace>',
    password: '<password>',
    username: '<username>',
  }),
})

await db
  .create('person:100')
  .set({
    first_name: 'Jennifer',
    age: 15,
  })
  .return('none')
  .execute()

Why not write a query builder from scratch

Kysely is growing to be THE sql query builder solution in the typescript ecosystem. Koskimas' dedication, attention to detail, experience from creating objection.js, project structure, simplicity, design patterns and philosophy, made adding code to that project a really good experience as a contributor. Taking what's great about that codebase, and patching in SurrealQL stuff seems like an easy win in the short-medium term.
