Connection failure

Hello,

After installing requirements.txt, I see following errors:
Traceback (most recent call last):
File "run.py", line 1, in

Do I need to install mongodb first?

Yes, you need to install mongodb first.

Your steps are:

1. install mongodb using your method of choice.
2. start the mongo server. Either use 'mongod' or 'service mongodb start' in the console.
3. then follow the instruction in the README to run flask.

if you don't want to install mongodb on your machine, you can use mlab.com to host your database. Then i think you'll have to update flask-react-todo/api/init.py with the server config. Something like this

app.config['MONGOALCHEMY_SERVER']='mlab:server:config'
