How to auto "update" templates?

Question

Flask

There is a code that outputs index.html:

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def main():
    return render_template("index.html")

if __name__ == '__main__':
    app.run()

When the server is running, any changes to index.html will not output the modified file.
I couldn't find it on Google, but I've been looking for a long time.
How to make auto "update"?

Answer 1

This can only be done in debug mode, for this you need to pass the debug=True parameter to the run method . In production, this greatly reduces performance. It's better to configure the WSGI server to restart under certain conditions, and create those conditions on changes.

Answer 2

Through a parameter in the config:
app.config["TEMPLATES_AUTO_RELOAD"] = True
