EMS-ESP32/mock-api/README.md

(Based on https://github.com/emsesp/EMS-ESP32/issues/41)

When developing and testing the web interface, it's handy not to bother with re-flashing an ESP32 each time. The idea is to mimic the ESP using a mock/stub server that responds to the REST (HTTP POST & GET) and WebSocket calls.

To use first make sure you have nodejs installed (>v18) then install yarn (npm install -g yarn). Now type yarn from this mock-api folder. To run EMS-ESP's WebUI navigate up to the interface folder and type yarn run standalone. This will start the mock API server on port 3080 using static dummy data from mock-api/server.js and also the web server which is at http://localhost:3000.
