• 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
