Which is better to use: decorator or before_request?

Question

Flask

There are options:
1) Use a decorator for private parts of the site where authorization is required:

@login_required
@app.route('/members/' )

And if there are 100500 routes in the closed part of the site, then you need to add 100500 lines with @login_required.
Yes, and forget you can inadvertently stick it.
2) Use before_request once.

@app.before_request
def before_request():
    user_id = session.get('user_id', None)
    if not user_id and request.path.startswith('/members/'):
        return redirect(url_for('login'))

Which option is correct?

Answer 1

There is no correct option.
See what you need specifically in your case.
You can compare them for response speed, memory consumption and more, more.
