Set up nodejs app on Macbook using Docker

There is a website called freeCodeCamp, in which you can learn web design and programming. The source code is open and we can read the code. The source code is here: [login to view URL] And in the repository, there is a setting up file for Docker. I read the article about setting up the app on laptop: [login to view URL] What I did was: $ cd freeCodeCamp $ npm install $ bower install $ npm run build $ cp [login to view URL] .env $ echo NODE_ENV=production >> .env $ docker-compose up I can almost run the app. I can access to the app on "localhost:3000" and I can load the quiz data. But I cannot load the editor pane and challenge the quiz. I'd like you to help me to set up the environment on my Macbook. You can use Teamviewer and do remote control. The environment is 　・High Siera 10.13.3 　・Docker(Version 17.12.0-ce-mac49 (21995))
