• MongoDb
• Studio 3T
• reactjs, Redux
• micro-services
• nginx
• docker, docker-compose

Setting Up

1. Clone/Download the Repository

$ git clone repo_url

2. Install Dependencies

$ npm install (in each folder: app, customer, shopping, products)

3. Configure env variables

• Create .env.dev file in each folder (app, customer, shopping, products).
• Set the value of the variables based on the example file sample_env.

4. Start services

$ docker-compose -f docker-compose.yml up
