Running the BLXM Smartbridge

1. Create .env file at /src

---

An .env file is needed otherwise the application won’t start. The .env file is placed in /src (in the backend). The logic and structure of the .env file is described in the following:

PRIVATE_KEY_BSC=<PrivateKeyForBSCAdress>
PRIVATE_KEY_ETH=<PrivateKeyForETHAdress>
MONGODB_URL=<DatabaseURL>
TOKEN_SECRET=<JWTTokenSecret>
JSON_RPC_API_KEY=<JSONRPCKeyMainnet>
JSON_RPC_API_KEY_TESTNET=<JSONRPCKeyTestnet>
NODE_ENV=production

When NODE_ENV=production is set the Smartbridge operates in BSC/ETH mainnet.

2. Installing and Importing

---

Install npm dependencies:

cd src
npm install

cd frontend
npm install

3. Start the api and frontend locally

---

Two different processes

Backend:

cd src
npm run dev

App is running ...
Press CTRL + C to stop the process.

Frontend:

cd frontend
npm run dev

Compiled successfully!

You can now view frontend in the browser.        

  Local:            http://localhost:3000        
  On Your Network:  http://172.24.192.1:3000 

4. Create .env file for production mode at /frontend

---

An .env file is needed in the frontend to set the production api url, otherwise it will be set to http://localhost:8080/ by default for development mode:

REACT_APP_API_URL=http://<API_URL>/

5. Frontend Production Build

---

Run the following commands at /frontend:

npm run build

To serve the production build run at /frontend:

serve -s build

... 

Serving!           

   │                                                   │
   │   - Local:            http://localhost:3000       │
   │   - On Your Network:  http://192.168.2.100:3000   │
   │                                                   │
   │   Copied local address to clipboard!              │
                                                  

6. Backend Production Build

---

Run the following commands at /src to create a docker image:

docker build -t production .

To run the docker image as a container:

docker run -p 8080:8080 production
... 

App is running ...

Press CTRL + C to stop the process.                                               

To map the containers port to a host port use the -p command, so the container is accessible from outside the container. (https://docs.docker.com/engine/reference/commandline/run/)
