# 🛡️ DID Proxy Resolver

This project is a simple **Node.js + Express** proxy API that resolves `did:tgrid` identifiers by internally calling a DID resolver running on `http://localhost:3000`.

It exposes an endpoint:

GET /1.0/identifiers/:identifier

Which internally calls:

GET http://localhost:3000/resolve?did=did:tgrid:trustgrid:dev:

## 🚀 How to Run

### 1. Install dependencies

```bash
npm install

2. Start the server

node index.js

Server runs at http://localhost:8080

---

🔁 Example Request

Call this proxy endpoint:

curl http://localhost:8080/1.0/identifiers/QjA1qdXKmxzgK4u8mFoBpF

It will internally send a request to:

http://localhost:3000/resolve?did=did:tgrid:trustgrid:dev:QjA1qdXKmxzgK4u8mFoBpF

And return the resolved DID Document.

🐳 Docker Support

Build the image

docker build -t did-proxy .

Run the container

docker run -p 8080:8080 did-proxy

---

🧱 Docker Compose (optional)

If you're running the DID resolver (on port 3000) and this proxy together:

docker-compose.yml

version: '3.8'

services:
  resolver:
    image: your-did-resolver-image
    build:
      context: ./resolver
    ports:
      - "3000:3000"

  proxy:
    build: .
    ports:
      - "8080:8080"
    depends_on:
      - resolver

Make sure to update controllers/Default.js to call:

const url = `http://resolver:3000/resolve?did=...`

instead of localhost.
