Google says that MarkupSafe makes jina2 run faster here

I’ve added it to my Yaml file like this.

libraries:
- name: webapp2
  version: "2.5.1"
- name: jinja2
  version: latest
- name: markupsafe
  version: latest

Jina2 says it checks to see if markupsafe is installed here

My question is, how do I really know it is working? I inserted a bunch of html via my jinja form and it didn’t get escaped. In short, I’ve read the docs and can’t find a clear answer to what markupsafe does, and why I need it. The only snippet of information I have that jinja2 looks for it and makes jinja faster. I have no idea if its really working.

    AFAIK markupsafe doesn’t affect the jinja2 semantics, only its performance. So the only way to find out if it worked is to time it. Or you could stop worrying. 🙂 That app.yaml syntax looks fine.

    If you want jinja2 to escape your variables, you must turn on autoescape when creating the Environment, like this:

    env = jinja2.Environment(
  loader=jinja2.FileSystemLoader(os.path.dirname(__file__)),
  autoescape=True)
