Feature Flag Demo

What it is?

A prototype for showing how we can handle feature change based on feature flag.

Tech stack

• Nuxt for frontend, served by Nginx
• FastAPI for backend
• Postgres for database
• Flagr for feature flag
• Docker compose for orchestration

Architecture

Nuxt --(auth)--> FastAPI
                    |
                    # success, check with user id
                    |
                    |------------> Flagr
                    |<------------ 
                    |
                    # receive feature list with enable flag
                    |
Nuxt <---------- FastAPI
# FE save and render
