Install dependencies:

npm install -g grunt-cli
npm install

Create a file called .env in the root of the project. Put the following in it:

ROOT_URL=https://blockchain.info/

Grunt watches and compiles the Javascript. Keep it running:

grunt

Run local http server:

npm start

Visit local.blockchain.com:8080. Do not use localhost:8080. You will need to modify your "hosts" file (/etc/hosts on OSX and most UNIX systems) because this is no longer registered at the DNS level for application security reasons. Add this line to /etc/hosts:

127.0.0.1   local.blockchain.com
