Jinja2 VS starlette

But, on the other hand, I can read in the jinja repository that there is not the same Switching From Other Template Engines and also exists documentation about Support for templates engines

jinja: Default templating engine for and dependency of flask

or as complex as bringing Jinja into the picture. Some other options include mustache templates, the built in Template class, and some libraries noted here.

Jinja

Hey u/GuzTech , this issue is mostly related to an old version of jinja that you might be using, here is the report: https://github.com/pallets/jinja/issues/1585

Turns out it wasn't how I was getting the variable -- registered from the api call VS lookup('file') -- it was mainly that for some reason, using 'map()' sometimes needs ' | list | to_json ' tacked on to the end to correctly output the results without the "generator object do_map at xxxx" instead (as mentioned here).

Cookiecutter is a command-line utility that creates projects from templates. There's a list of templates maintained by the cookiecutter team and plenty of community awesome lists. It's built with python and uses the jinja templating framework (found in python web frameworks like flask). You can use it to make a template for pretty much anything! All you need to get started is pip install cookiecutter.

This major release of Flask is accompanied by major releases of Werkzeug, Jinja2, click, and itsdangerous which we'd also welcome and appreciate testing (their pre releases are installed with the Flask pre release).

Fast Execution: FastAPI is built on top of Starlette and Pydantic, making it one of the fastest Python frameworks for building APIs.

The framework's efficiency comes from its use of Starlette for building asynchronous web services and Pydantic for robust data validation and serialization, powered by Python's type hints. Pydantic has recently announced the official release of Pydantic V2 (June 2023), which is a ground-up rewrite that offers many new features and performance improvements, so make sure to be using that instead of V1.

Starlette documentation

Same here, but without these weird utils it doesn't get any better.

I have 7 YoE with Django. Its great at so many things. You see some code, like middlewares, and immediately understand what's going on.

Now, we also have Starlette. The base of all new, fancy asgi libraries. Here's the base middleware class.

In the last couple of years I heard 'we're running fastapi on production. Wanna join us?' so many times... but the reality is that it's still not suitable for prod. Who wants to work with a code like that if you have a readable, stable Django? I'm clueless.

Set up Starlette, a tool we'll use to make async requests

I never used websockets in FastAPI so I wouldn't know how to guide you more, but Middleware in Websockets are 100% supported by Starlette : https://github.com/encode/starlette/issues/641

Websockets are the way but I would not recommend django as it's still not fully async. I would go for other tools.
