SOA-based distributed online payment system. Intended for generic educational institutions transactions.

Although Paidify should ideally be mounted in distributed servers accross a network, here is a guide to run it locally.

This process is guided by the run-local app. It will start 11 terminals, one for each service instance.

• Node.js.
• Docker along with Docker Compose.

1. Clone run-local repository.

   git clone https://github.com/Paidify/run-local.git
   

2. Install dependencies and start the application.

   npm install && npm start
   

3. Follow the steps shown in the application.

You will press enter to confirm launching each terminal. It is recommended to leave a reasonable amount of time between each service, so that your PC can run them properly.
