About

• Provides AsyncJinja2Templates class which enables use of the is_async Jinja environment flag with Startlette and Starlette based applications like FastAPI

• Only asynchronous template loaders (not yet tested but should work) are currently supported

• The Jinja bytecodecache requires an asynchronous Redis backend

    return await templates.TemplateResponse(request, 'index.html')

or:
