Flask: How to serve static html?

Question

I am trying to serve a static html file, but returns a 500 error (a copy of editor.html is on .py and templates directory) This is all I have tried:

from fla         


        

Answer 1

send_from_directory and send_file need to be imported from flask.

Your code sample would work if you do the following:

from flask import Flask, send_from_directory
app = Flask(__name__, static_url_path='/templates')

@app.route('/')
def hello_world():
    return send_from_directory('templates', 'editor.html')

However, remember if this file loads other files e.g. javascript, css, etc. you would have to define routes for them too.

Also, as far as I understand, this is not the recommended method on production because it's slow.
