Automatically generating a client-side application based on available components is provided. A source code and related build information of a component is stored in a component repository. The component is developed in a developer mode of a developer tool. An existing single-page application is changed using a non-expert editing tool by selecting a component from the component repository, retrieving the selected component from the repository, extracting build information from the retrieved component, adding dependencies regarding the retrieved component to a single-page packaging of the existing single-page application, and compiling the single-page application together with the retrieved component.
