🏃 How to run

This project was developed using a Google Cloud Platform virtual machine, so every step must be performed in a VM CLI under a sudo -s command.

Start your VM and save the highlighted External IP:

You must have Fabric samples to run this project. You will clone this project inside fabric-samples folder so as to this can use the files from bin and config folders.

Here you can see the folder structure and the main files mentioned in this section:

📦fabric-samples
 ┣ 📂bin
 ┣ 📂config
 ┗ 📂eKYC
   ┣ 📂api
   ┣ 📂chaincode
   ┣ 📂frontend
      ┗ 📂src
         ┗ 📂service
            ┗ 📜baseURL.json
   ┣ 📂test-network
   ┣ 📜.env
   ┣ 📜networkDown.sh
   ┗ 📜setUp.sh

Open your terminal in the fabric-samples folder and clone the project.

# Clone this repo
git clone https://github.com/LorranSutter/eKYC.git

# Go to the project folder
cd eKYC

To run the application you will need to set your own configurations of port, database, private key and encryption key. Create the following .env file in the indicated path and format with your customized configurations:

// ./.env

PORT_API=5000
PRIVATE_KEY="54AD766F231CCB0EA64156F1E5488"
ENCRYPTION_KEY="CoCKidLqlVuB8y1EYmKaye1UGoxtHmko1LmyqOHvVht="
MONGODB_URI_DEV="YOUR_DEV_MONGO_URI"

Now you will need two opened terminals to run the project. One for the API and another one for the frontend.

API will run on http://35.193.245.108:5000/

Frontend will run on http://35.193.245.108:3000/

## In the first terminal ##

# Go to the chaincode folder
cd chaincode

# Install dependencies
npm install

# Go to the API application
cd ../api

# Install dependencies
npm install

## In the second terminal ##

# Go to the frontend application
cd frontend

# Install dependencies
npm install

In order to connect frontend to the API, you will have to provide the base URL of the API in the following file:

## In the second terminal ##

# Go to the baseURL.json file
cd src/service/baseURL.json

{
    "baseURL": "http://35.193.245.108:5000"
}

Now you can start the network and perform all necessary set up running the following magic script:

## In the first terminal ##

# Go to the root
cd ..

# Run the set up script
./setUp.sh

Run the API application:

## In the first terminal ##

# Go to the API application
cd api

# Run API application
npm run start

# Or to use nodemon
npm run dev

Finally run the frontend application:

## In the second terminal ##

# Run the project
npm start

If you want to stop the network and delete all artifacts created, just run the next magic script below:

## In the first terminal ##

# Go to the root
cd ..

# Run the script
./networkDown.sh
