@streamby/core

Middleware framework for building storage-agnostic media APIs.
Part of the StreamBy ecosystem by TerminalCore Labs.

---

🚀 What is it?

@streamby/core is a plug-and-play middleware for Express (or compatible frameworks) that enables file uploads, listings and multi-project access over services like:

• ✅ AWS S3
• ✅ Google Cloud Storage (soon)
• ✅ Cloudflare R2 (soon)
• ✅ Local/Personal servers (soon)

It's designed to be installed inside your existing API as a library — no need to run a separate backend.

📦 Installation

npm install @streamby/core

🧱 Basic usage

🗄️ Database Schema Setup

@streamby/core requires a pre-configured database schema for its internal operations. It does not manage database connections directly; instead, it expects the host application to provide initialized connection instances. This ensures full control and flexibility for the host environment.

The library will only interact with the specified schema and will not touch other schemas in your database. The reset option is opt-in and will only drop and recreate the specified streamby schema if explicitly set to true.

PostgreSQL Example

import { Pool } from "pg";
import { setupStreambyPg } from "@streamby/core/pg/setup"; // Adjust path as per your package structure

const pool = new Pool({ connectionString: process.env.DATABASE_URL });

// Call setupStreambyPg to ensure the schema and tables are created
// reset: false (default) ensures idempotency and no data loss
await setupStreambyPg({ pool, schema: "streamby", reset: false });

MongoDB Example

import { MongoClient } from "mongodb";
import { setupStreambyMongo } from "@streamby/core/mongo/setup"; // Adjust path as per your package structure

const client = new MongoClient(process.env.MONGO_URL!);

// Connect the MongoDB client
await client.connect();

// Call setupStreambyMongo to ensure collections and indexes are created
await setupStreambyMongo({ client, dbName: "streamby" });

import express from 'express';
import { createStreamByRouter } from '@streamby/core';

const app = express();

app.use('/streamby', createStreamByRouter({
  storageProvider: {
    type: 's3',
    config: {
      bucket: 'your-bucket-name',
      region: 'your-region',
      accessKeyId: 'YOUR_AWS_KEY',
      secretAccessKey: 'YOUR_AWS_SECRET'
    }
  },
  authProvider: async (req) => {
    // extract token/cookie and validate
    return {
      userId: 'demo',
      projects: ['demo-project'],
      role: 'admin',
    };
  },
  projectProvider: async (projectId) => {
    // fetch project from your DB
    return {
      id: projectId,
      name: 'Demo Project',
      description: 'Demo for StreamBy integration',
      rootFolders: [],
      settings: { allowUpload: true }
    };
  }
}));

app.listen(3000);

🗺️ API Endpoints

Here's a summary of the key API endpoints provided by @streamby/core:

GET /streamby/projects

Lists all projects accessible by the authenticated user.

Query Parameters:

• archived: (Optional) Filter projects by their archived status.
  • true: Returns only archived projects.
  • false: Returns only unarchived projects.
  • (Omitted): Returns all projects (both archived and unarchived).

Example Response:

{
  "projects": [
    {
      "id": "project1_id",
      "dbType": "nosql",
      "name": "My NoSQL Project",
      "image": "url_to_image",
      "archived": false
    },
    {
      "id": "project2_id",
      "dbType": "sql",
      "name": "My SQL Project",
      "image": "url_to_image",
      "archived": true
    }
  ]
}

PATCH /streamby/projects/:id/archive

Archives a specific project. After archiving, it returns the complete list of projects for the user, including the updated project.

Example Response:

{
  "success": true,
  "projects": [
    {
      "id": "project1_id",
      "dbType": "nosql",
      "name": "My NoSQL Project",
      "image": "url_to_image",
      "archived": true
    },
    {
      "id": "project2_id",
      "dbType": "sql",
      "name": "My SQL Project",
      "image": "url_to_image",
      "archived": false
    }
  ]
}

PATCH /streamby/projects/:id/unarchive

Unarchives a specific project. After unarchiving, it returns the complete list of projects for the user, including the updated project.

Example Response:

{
  "success": true,
  "projects": [
    {
      "id": "project1_id",
      "dbType": "nosql",
      "name": "My NoSQL Project",
      "image": "url_to_image",
      "archived": false
    },
    {
      "id": "project2_id",
      "dbType": "sql",
      "name": "My SQL Project",
      "image": "url_to_image",
      "archived": false
    }
  ]
}
