Please run front-end server by executing npm start under the folder gpt-writing-frontend, the server will default run on port 3000 in development mode.
Note: You may need to update the backend API URLs used in the current frontend server to the URL of the backend server that you run. A simple way is to search visar.app/api under the folder gpt-writing-frontend and replace all of the occurences to your back-end server URL (default should be localhost:8080).
Go to folder gpt-writing-backend. Please run the back-end server by executing python server.py. Make sure to install the dependency listed in gpt-writing-backend/requirement.txt first. Please create an file gpt-writing-backend/openai_key.json and put your OpenAI key in the following JSON form:
{
key: "Your OpenAI key"
}
Similarly, create a file called gpt-writing-backend/mongoDB_key.json and store your MongoDB key in the same form. You need to create a new mongoDB database called "gptwriting", and create collections called "users" and "interactionData" in the database.
