A tutorial series demonstrating how to get a sentiment analysis on chat messages

One-to-one private chat with sentiment analysis using Pusher Channels, Flask and Vue.js

This tutorial series demonstrates how to build a chat app with sentiment analysis using Pusher Channels, Flask and Vue.js. You can read the tutorial on how it was built here:

• Part one
• Part two
• Part three
• Part four

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

This application uses the following:

• Python 3.6+
• Node.js version 8.9 or above
• Vue cli

Setting up the project

First, clone this repository to your local machine:

 $ git clone https://github.com/dongido001/pusher-chat-sentiment-analysis.git

Next, update the following keys in the api/.env file with your correct Pusher keys:

PUSHER_APP_ID=app_id
PUSHER_KEY=key
PUSHER_SECRET=secret
PUSHER_CLUSTER=cluster

Then, update the .env file in the project’s root folder with your correct Pusher App key:

    VUE_APP_PUSHER_KEY=<PUSHER_APP_KEY>
    VUE_APP_PUSHER_CLUSTER=<PUSHER_APP_CLUSTER>

Running the Apps

Run the Flask app

• Using your terminal, navigate into the Flask folder - api:

    $ cd api

• Create a virtual environment:

python3 -m venv env

• Activate the virtual environment:

  source env/bin/activate

On windows? Activate it with the below:

  source env/Scripts/activate

• Install the dependencies:

pip install -r requirements.txt

• Download NLTK corpora:

$ python -m textblob.download_corpora lite

• Finally run the app:

 flask run

Check the URL where Flask is running - http://localhost:5000. You will get a text "Pong!".

Run the Vue app

Open a new terminal window, then navigate into the projects root folder - one-to-one chat:

Install dependencies:

npm install

Then run the app:

    $ npm run serve

Built With

• Flask - A microframework for Python
• Pusher - APIs to enable devs building realtime features
• Vue.js - A JavaScript Framework for building User Interfaces

pusher-chat-sentiment-analysis's Issues

I'm interested in testing and modifying this project a bit..but it seems severely outdated

It's a very cool concept and I'm interested in playing around with it a bit, but so far I've been running into many issues some of which i'm not sure if it was just a me thing or something with the project itself. Some are with outdated modules.

For example the later versions of python don't have the clock attribute under time.

I seem to have fixed that particular issue, but now even after creating the registration and getting a message from postman that the user was successfully created I still get login failed error.

Please update, or help me navigate these errors. I'm mainly interested in adding a user registration option to the main interface rather than requiring to do it via postman.

What service would I use if I want to deploy both on one server? And need to resolve database issues

I have taken this application, and altered it into something significantly different and now I'm seeking to deploy this app. Currently I have the frontend (which would be localhost:8080) running on firebase, and I have the backend (which would've been localhost:5000) on pythonanywhere? Anywhere where I could use one service and have them both deployed?

Also when I try to get or post data to the database I receive this error on my backend:

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: users [SQL: 'SELECT users.id AS users_id, users.username AS users_username, users.password AS users_password \nFROM users \nWHERE users.username = ?\n LIMIT ? OFFSET ?'] [parameters: ('jama juice', 1, 0)] (Background on this error at: http://sqlalche.me/e/e3q8)

Anyway I can resolve this database issue? I have everything set up correctly.

Proxy error

I'm getting this error:

Proxy error: Could not proxy request /api/login from localhost:8080 to http://127.0.0.1:5000.
See https://nodejs.org/api/errors.html#errors_common_system_errors for more information (ECONNREFUSED).

Even after I replaced localhost with 127.0.0.1. Do you have other suggestions?

Content not visible for App.vue component

The 2nd part of the tutorial:

• https://pusher.com/tutorials/chat-flask-vue-part-2

is missing content at the end in an LI tag. Possibly because it has a Vue template? and isn't surrounded by {% verbatim %}?
