HUB Upload API

This is the Upload API for HUB. It allows users to upload files to the server using the Bundlr service.

Setup

To setup the server, follow these steps:

1. Install the dependencies by running npm install
2. Set the environment variables IRYS_GATEWAY, IRYS_URL, SOLANA_RPC_URL, and SOLANA_KEYPAIR. Note that IRYS_GATEWAY should be an Arweave compatible gateway for retrieving assets over HTTP.
3. Start the server by running npm start

Routes

The available routes are:

• POST /uploads: Upload a file or JSON. This route accepts either a file as multipart/form-data or a JSON object and returns the URI and CID of the uploaded file.

Swagger Documentation

The Swagger documentation for the API is available at /documentation.

Error Handling

If there is a validation error in the request, the server will respond with a 400 status code and the validation error.

File Upload

The server uses the fastify-multipart plugin to handle file uploads. The server is configured to accept a maximum of 1 file field and 0 non-file fields.
