Question 1

How to set up fastapi-chameleon for server-side rendering in FastAPI?

Accepted Answer

Install the package with pip, initialize it using fastapi_chameleon.global_init() with your template folder path, and decorate view functions with @fastapi_chameleon.template(). Return a dictionary from the view to pass data to the Chameleon template.

Question 2

fastapi-chameleon vs fastapi-jinja: which should I choose?

Accepted Answer

Opt for fastapi-chameleon if you're committed to Chameleon templates for their XML-based syntax; choose fastapi-jinja if you prefer Jinja2's more popular ecosystem and familiar syntax. Both offer similar decorator-based integration with FastAPI.

Question 3

How to handle custom 404 pages with fastapi-chameleon?

Accepted Answer

Call fastapi_chameleon.not_found() in your view method when a resource is missing. By default, it renders a 404.pt template from the errors folder, but you can customize the template path as needed.

Question 4

Does fastapi-chameleon work with asynchronous views in FastAPI?

Accepted Answer

Yes, it fully supports asynchronous view functions (async def) as demonstrated in the README examples, allowing seamless integration with FastAPI's async capabilities for non-blocking operations.

Question 5

Can I use dependency injection with fastapi-chameleon templates?

Accepted Answer

Yes, FastAPI's dependency injection works normally with decorated view functions; you can inject dependencies before the template renders, making it easy to pass services or data to templates.

Question 6

How to enable template auto-reload in development mode?

Accepted Answer

Set auto_reload=True when calling fastapi_chameleon.global_init() during app startup, typically based on a development environment flag, to automatically refresh templates on changes without restarting the server.
