## Local development setup

Clone this repository to a directory on your machine

    git clone https://gitea.dgov.io/DGF/dgf-prototype

### Nginx

1. Install nginx

        brew install nginx


1. Install mkcert

        brew install mkcert

1. Install root CA

        mkcert -install

1. Create a certificate

        mkcert dgfprototype.dev
         
1. Create certificates directory

        sudo mkdir /etc/nginx/certs

1. Move the certificate to the certificates directory

        sudo mv dgfprototype.*.pem /etc/nginx/certs/

1. Add the following to the `http` section of `/etc/nginx/nginx.conf`

        map $http_upgrade $connection_upgrade {
            default upgrade;
            '' close;
        }

1. Add the following to a new file `/etc/nginx/sites-available/dgfprototype_dev`

        server {
                listen 443 ssl;

                server_name dgfprototype.dev;
                ssl_certificate     /etc/nginx/certs/dgfprototype.dev.pem;
                ssl_certificate_key /etc/nginx/certs/dgfprototype.dev-key.pem;

                location /api/ {
                        proxy_pass http://127.0.0.1:3003/;
                }

                location / {
                        proxy_pass http://127.0.0.1:3002/;
                        proxy_http_version 1.1;
                        proxy_set_header Upgrade $http_upgrade;
                        proxy_set_header Connection $connection_upgrade;
                        proxy_set_header Host $host;
                }
        }

1. Create a symbolic link in `sites-enabled/`

        sudo ln -s /etc/nginx/sites-available/dgfprototype_dev /etc/nginx/sites-enabled

1. Restart nginx

        sudo systemctl restart nginx

    or

        sudo brew services restart nginx

1. Edit `/etc/hosts` to add the domain alias

        127.0.0.1  dgfprototype.dev

### API

1. In a new terminal window, navigate to `dgf-prototype/backend`

1. Install the project

        npm install

1. Copy the example configuration file

        cp .env.example .env

1. Edit `.env` and set the following values

        PORT=3003

1. Create the data directory

        mkdir data

1. Run the daemon

        node src/index.js

### Hardhat

1. In a new terminal window, navigate to `dgf-prototype/ethereum`

1. Install the project

        npm install

1. Copy the example configuration file

        cp .env.example .env

1. In `.env`, set a value for `SEED_PHRASE` or `LOCAL_PRIVATE_KEY`

1. Run a hardhat node

        npx hardhat node

1. In a separate terminal window, navigate again to `dgf-prototype/ethereum`

1. Build and deploy the contracts

        npm run deploy-local

### Metamask
