Configuration settings are sourced from a .env file and a config module. Ensure you have the necessary environment variables set up in your .env file.

1. Clone the repository:

   git clone https://github.com/rizzolib/ordinal-marketplace.git 
   cd ordinal-marketplace

2. Install the dependencies:

   npm install

3. Create an .env file and add your environment variables:

   NETWORKTYPE=TESTNET
   PORT=3000
   MONGODB_URI=mongodb://localhost:27017/ordinalsbot
   

   You can reference .env.example file configuration.

4. Start the server:

   npm start

After starting the server, the application will be running on the specified port. By default, it is set to port 3000. You can access the backend running status at http://localhost:3000 and see the Swagger API documentation at http://localhost:3000/api-docs.

The following routes are available in the application:

• POST /api/create-listing: Create a new listing.
• POST /api/save-listing: Save listing data.
• DELETE /api/delete-listing: Delete an existing listing.
• PUT /api/update-listing: Update an existing listing.
• POST /api/create-offer: Create a new offer for a listing.
• POST /api/submit-offer: Submit an offer for a listing.

The MongoDB schema used in this project is as follows:

import mongoose from "mongoose";

const OrderSchema = new mongoose.Schema({
  ordinalId: { type: String, required: true, unique: true },
  price: { type: Number, required: true },
  sellerPaymentAddress: { type: String, required: true },
  sellerOrdinalPublicKey: { type: String, required: true },
  status: { type: String, required: true },
  ordinalUtxoTxId: { type: String, required: true },
  ordinalUtxoVout: { type: Number, requred: true },
  serviceFee: { type: Number },
  signedListingPSBT: { type: String, required: true },
});

const OrderModel = mongoose.model("order", OrderSchema);

export default OrderModel;

Swagger UI is integrated to provide an interactive API documentation. You can access it at http://localhost:3000/api-docs. This documentation will dynamically reflect the API endpoints of the application.
