How to Setup

Clone the repository.

git clone https://github.com/scorelab/Labellab.git

Run npm install in labellab-client folder.

 cd labellab-client/
 npm install

Set up MongoDB backend

Run npm install in labellab-server folder.

How to Use

First you need to create a .env file in both labellab-server folder and labellab-client folder following the template provided in the file .env.example which is present in both the folders.

For client-side .env file:

REACT_APP_HOST=http://localhost
REACT_APP_SERVER_ENVIORNMENT=dev
REACT_APP_SERVER_PORT=4000

For server-side .env file:

HOST=localhost
PORT=4000

JWT_SECRET can be any word your choice.

To create a free MongoDB Atlas cloud database, follow the guide at https://docs.atlas.mongodb.com/getting-started/. After setting up, find the conection string to your database. It should look like this:

{{DB_HOST}}://{{DB_USERNAME}}:{{DB_PASSWORD}}@{{DB_CLUSTER}}/{{DB_NAME}}

You should fill in these values in their relevent fields in the .env file.

NOTE: Your IP address may change if you've been disconnected from the internet and reconnected. If that happens, it means that your internet connection doesn't have a static IP. You may no longer be able to access the database if you've whitelisted only your previous IP address. You can allow access from any IP address from the Atlas control panel to overcome this issue.

Both the front-end and the back-end can be run from the labellab-server folder using the terminal:

To run both the client and server with a single command, run the following:
$ npm run dev
To run the server separately:
$ npm run server

The server can also be run using $ npm start

To run the client separately:
$ npm run client

NOTE: Before starting the server create a file named .env same as .env.example and add your OAUTH and DATABASE credentials in the file.

Visit localhost:3000 to browse.

NOTE: This version only supports Google Chrome and Mozilla Firefox browsers. Make sure to instal the extension Redux Dev Tools if you're using Google Chrome.
