Data Adapter

Defines how session data is stored.

const rp = await OidcClient.factory({
  //...
  dataAdapter: OIDCClientDataAdapter,
  //...
})

The package includes data adapters using SQLite/LokiJS/Lowdb/Redis.
You can make your own adapters.
SQLite with in-memory option is used by default.
When using multiple OP, share a single data adapter.
Ref: OIDCClientDataAdapter

SQLite

Use Bun built-in SQLite driver.

import { SQLiteAdapter } from 'elysia-openid-client/dataAdapters/SQLiteAdapter';

// In-memory
const memoryAdapter = new SQLiteAdapter();
// Same as `new SQLiteAdapter({ filename: ":memory:" })`

// Persistence to file
const fileAdapter = new SQLiteAdapter({
  filename: "path/to/sessions.sqlite"
});

LokiJS

Use LokiJS.

bun add lokijs
bun add -D @types/lokijs

// In-memory
import { LokiInMemoryAdapter } from 'elysia-openid-client/dataAdapters/LokiInMemoryAdapter';
const memoryAdapter = new LokiInMemoryAdapter();

// Persistence to file
import { LokiFileAdapter } from 'elysia-openid-client/dataAdapters/LokiFileAdapter';
const fileAdapter = await LokiFileAdapter.factory({
  filename: "path/to/sessions.db"
});

Lowdb

Use Lowdb.

bun add lowdb

import { LowdbAdapter } from 'elysia-openid-client/dataAdapters/LowdbAdapter';

// In-memory
const memoryAdapter = await LowdbAdapter.factory();

// Persistence to file
const fileAdapter = await LowdbAdapter.factory({
  filename: "sessions.json",
})

Redis

Use Redis with ioredis.

bun add ioredis

import { RedisAdapter } from 'elysia-openid-client/dataAdapters/RedisAdapter';
const redisAdapter = new RedisAdapter({
  port: 6379,
  host: "localhost",
});

Creating your own adapters

import type { OIDCClientDataAdapter } from 'elysia-openid-client';
export class MyDataAdapter implements OIDCClientDataAdapter {
  // ...
}

// app.ts
import { MyDataAdapter } from 'path/to/MyDataAdapter';
const rp = await OidcClient.factory({
  //...
  dataAdapter: new MyDataAdapter(),
  //...
})
