What to use as front + back?

Question

Python

Good afternoon. Point the right way, there are temperature/humidity sensors in the facility. I wrote a program for collecting data using the modbus protocol; I collect data and write to the mysql database. It is necessary to draw a web face for this, a kind of plant plan with real-time information display + a page with a graph for the elapsed time. There is an assumption that use flask for the front + charts.js for charts + synchronously or asynchronously pull data via modbus, or run a separate daemon process that pulls information and adds it to the database, and the server on flask runs in mysql and from there pulls the latest data for real time + time periods for plotting. Maybe there is some other alternative, advise what to choose for the implementation of this project.

Answer 1

If you need to build graphs, then some process must poll the sensors after a given interval - this is a no-brainer. And there is no need to synchronize this process with the web. You may not visit the web for a week, but when they do, what to do, there is no data. Vobschem cutlets separately, flies separately. If instantaneous values ​​are needed, then request them from the web with a separate request - ajax. There is no need for page loading to slow down. To display a plant map, I would take OpenLayers.
