Achievement​

  • React
  • Python
    • FastAPI
      • smaller and simpler then flexible than nonolithic Django
      • we have to composite other tools such as for migrations and for ORM
      • instead, we can customize it for our favor
    • Pydantic
      • better than Django REST framework
      • but doesn't reach at all how we can handle objects far easily in JS/TS
      • so far, replacement Django with FastAPI doesn't solve my demand to backend TS
    • SQLAlchemy
      • API is similar to raw SQL so better to learn and use than Django models and queries
      • i don't want ORM to wrap a logic part of SQL such as join and where or so by like filter() or query() because they don't abstract them or make them easy to use at all, they just alias them.
        • i first assemble logic in raw SQL then i have to think of like how do i write this in ORM query API...what a waste of time!
        • most cumbersome when writing raw SQL is to convert result records to objects
        • that's all i want ORM to do
      • query API of SQLAlchemy v2.0 match my demand
