# UI Development Environment

This guideline describes how to setup-up a development environment for the Polypheny-UI. In the following, we describe two approaches.

## Prerequisites

First, make sure you have node.js installed.

Then, clone Polypheny-UI, open the root folder and run

npm install


If you want to build the project without having to install Angular, you can do so by executing

./gradlew npm_install


You should now be able to open the UI in your browser by entering the url http://localhost:4200/.

## Using angular

If you haven’t installed Angular yet, do so by executing

npm install -g @angular/cli


Now you can run

ng serve --aot -o


You should now be able to open the UI in your browser by entering the url http://localhost:4200/.
