Reflections on Personal Project Architecture
Thoughts on Personal Project Architecture: In the current popularity of microservices and front-end and back-end separation, why should we do this? For personal development, there is no problem of division of labor in itself, doing so instead brings me a lot of unnecessary trouble. For simple personal projects, if the front end is just a CRUD display of the back-end data foundation, there is no need to separate. After "compressing" the entire system, I can package the entire project into a docker image with a single command, or directly go live on AppEngine, no longer need to worry about subsequent maintenance.
