This app is a front end client for Apache LENS server.

• It lets you fire queries.
• Discover cubes, its measures and dimensions.

• add your LENS Server address in package.json under scripts start and dev to lensserver argument, this is the value of lens.server.base.url property of your LENS installation
• default port is 8082, if you'd like to change it please change the port argument in package.json under scripts start or dev
• doing npm run dev starts the UI in dev mode, with the JavaScript assets in a non-minified way which help in debugging, also it'll be watching to the changes in the source and would generate the new assets automatically.
• doing npm run start will minify and uglifiy the assets.

cd lens-ui
npm run start

• this will cause your browser to make cross domain requests and if you don't have CORS enabled on your server, the app won't be able to get any data from LENS server.
  • to get around till you enable CORS on server side, open chrome in disabled web security mode.
  • first, quit chrome completely, then see the following steps to run browsers in disabled security mode
  • start chrome in disabled security mode

• All JavaScript is in app directory.
