Persistent Storage

This guide demonstrates using persistent storage instead of in-memory storage. Documents are persisted across server restarts using the unstorage abstraction layer.

What it demonstrates

• Using createUnstorage for persistent document storage
• Configuring unstorage with different drivers (memory, SQLite, Redis, etc.)
• Replacing in-memory storage with a persistent storage backend

Server Setup

import { createStorage } from "unstorage";
import { createUnstorage } from "teleportal/storage";
import redisDriver from "unstorage/drivers/redis";
import { Server } from "teleportal/server";

// Create unstorage instance with Redis driver
const storage = createStorage({
  driver: redisDriver({
    base: "teleportal:",
    url: "redis://localhost:6379",
  }),
});

const server = new Server({
  getStorage: async (ctx) => {
    const { documentStorage } = createUnstorage(storage, {
      documentKeyPrefix: "doc",
      fileKeyPrefix: "file",
      encrypted: ctx.encrypted,
    });
    return documentStorage;
  },
});

Alternative Storage Backends

PostgreSQL

import postgresDriver from "unstorage/drivers/postgres";

const storage = createStorage({
  driver: postgresDriver({
    connectionString: "postgresql://user:password@localhost/db",
  }),
});

SQLite

import sqliteDriver from "unstorage/drivers/sqlite";

const storage = createStorage({
  driver: sqliteDriver({
    db: "./teleportal.db",
  }),
});

S3

import s3Driver from "unstorage/drivers/s3";

const storage = createStorage({
  driver: s3Driver({
    bucket: "my-bucket",
    region: "us-east-1",
  }),
});
