mana-media - Unified Media Platform

Central media handling service for all Mana applications with content-addressable storage (CAS) and automatic deduplication.

Stack: Hono + Bun (migrated from NestJS 2026-03-28)

Overview

mana-media provides:

• Content-Addressable Storage - SHA-256 based deduplication across all apps
• Upload API - File uploads with automatic deduplication
• Processing - Thumbnails, WebP conversion, resizing (via BullMQ)
• Delivery - Optimized file serving, on-the-fly transforms

Port: 3015 (production)

Quick Start

# Start dependencies (Redis + MinIO + PostgreSQL)
pnpm docker:up

# Create database
PGPASSWORD=devpassword psql -h localhost -U mana -d postgres -c "CREATE DATABASE mana_media;"

# Install dependencies
cd services/mana-media/apps/api
pnpm install

# Push schema
pnpm db:push

# Start development server
pnpm dev

Service runs on http://localhost:3015

API Endpoints

Upload

# Upload file
curl -X POST http://localhost:3015/api/v1/media/upload \
  -F "file=@image.jpg" \
  -F "app=chat" \
  -F "userId=user123"

# Response
{
  "id": "abc123",
  "status": "processing",
  "hash": "sha256...",
  "urls": {
    "original": "http://localhost:3015/api/v1/media/abc123/file",
    "thumbnail": "http://localhost:3015/api/v1/media/abc123/file/thumb"
  }
}

Get Media

# Get metadata
GET /api/v1/media/:id

# Get by content hash (check if file exists)
GET /api/v1/media/hash/:sha256hash

# Get original file
GET /api/v1/media/:id/file

# Get thumbnail
GET /api/v1/media/:id/file/thumb

# Get medium variant
GET /api/v1/media/:id/file/medium

# On-the-fly transform
GET /api/v1/media/:id/transform?w=400&h=300&fit=cover&format=webp

List & Delete

# List media (filter by app/user)
GET /api/v1/media?app=chat&userId=user123&limit=50

# Delete
DELETE /api/v1/media/:id

Client Library

import { MediaClient } from '@mana/media-client';

const media = new MediaClient('http://localhost:3050');

// Upload
const result = await media.upload(file, { app: 'chat' });

// Wait for processing
const ready = await media.waitForReady(result.id);

// Get URLs
const thumbUrl = media.getThumbnailUrl(result.id);
const customUrl = media.getTransformUrl(result.id, {
  width: 400,
  format: 'webp'
});
