If you want to run the application, do:

1. Run the npm install or npm i for installing all dependencies. It will create node_modules directory.
2. Run the npm run start. The default port is 3000. But you can change in config/webpack.config.dev.js in port variable.

If you want to build the application, do:

1. Run the npm install or npm i for installing all dependencies.
2. Run the npm run build. Before running build, it automatically run npm run test for testing purpose. If the test has failure, it will cancel building the application. This code has coverage, and will be create coverage directory. After the test, the build is running and will be created dist directory.
3. Copy the dist folder, and put it to your web server / service.

Before you deploy, you must install Docker in https://www.docker.com/get-started if you Windows or Mac user. And for Linux user in https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-16-04

Steps for deploy with Docker:

1. Build the image with docker build . -t forex-app You can change the forex-app with another if you use this name already.
2. After that check your image with docker images. Please check your repository is in there.
3. Run the image with docker run forex-app. It will use http-server for serving the web server. If your port 8080 is already used. Please change the EXPOSE and -p with your available port.
