BlindChat

a facebook messenger bot that allows users to chat with other people on facebook anonymously. It's more like omegle for messenger, with some differences rather improvements.

You can find it live here

a bit of a background

I started out building BlindChat just to try out the messenger platform of facebook and try to build something usable out of it and learning in the process. It is more of an app rather than an AI chatbot. The outcome got a bit of traction and hence I improved certain parts of it. But most of the code may be in an unorganized condition since those are built for quick prototyping.

local development / setup your version of the app

BlindChat is currently hosted on heroku and also uses their offered database. So the code and setup are written for it. If you don't want to use heroku, you'll have to modify a few places. If you are okay with heroku, then you are just fine. It's better to have a bit of a knowledge setting up a messenger bot.

  1. Clone the repository. Open terminal/cmd and run git clone https://github.com/mayukh18/BlindChat.git/ and set up your local repository.

  2. Create a messenger app on facebook. Add and configure the webhook and note down the Access Token and Verify Token. Put them in config.py in their respective places.

  3. Create an app on heroku. Open up terminal/cmd and run heroku create yourappname. You'll find the app url as https://yourappname.herokuapp.com/. Put it on config.py. Do note that you'll first have to install the heroku CLI toolbelt if you don't have it.

  4. Next run pip install -r requirements.txt. This will install the libraries onto your local environment.

  5. Next run heroku addons:add heroku-postgresql:hobby-dev. This is the official guide from heroku on setting up a postgres db there. You'll find it pretty helpful.

  6. Next run these:

    heroku run python
>> import os
>> os.environ.get('DATABASE_URL')

  7. The url that you get from the above commands, that's your SQLALCHEMY_DATABASE_URI in config.py. Put it there.

  8. Next, to set up and migrate the models into your database, run

    python manage.py db init
python manage.py db migrate
python manage.py db upgrade

  9. You may find this memo helpful if you run into problems while set up. You may need to install PostgreSQL on your system if you run into some issues in the above step. Check this on the official guide.

  10. Next, deploy to heroku with git push heroku master. And voila!

directory structure

  1. DB_Wrappers: Contains the wrapper classes for the models in the database.
  2. modules: Contains all the functionalities from starting a chat session to sending a message.
  3. templates: Contains different message templates and webviews.
