REST Example

This repository illustrates how to use the the packages of h5p-nodejs-library in a Single Page Application with a REST backend in TypeScript.

Naturally the application is separated into a client, which uses React as a framework. The server implements the @lumieducation/h5p-server using Express. You are not bound to using React or Express in your own application, as @lumieducation/h5p-server is framework agnostic.

Check out the architecture overview that describes which parts of the application are provided by which package:

Architecture overview

• This repository contains all the components in purple boxes.

• The green parts come from one of the server-side packages of h5p-nodejs-library. While @lumieducation/h5p-server is also a dev dependency of the client, this is only the case to use the TypeScript interface definitions exported by it. The dependency (which can be rather large) is only required at build time and not at runtime.

• The red parts are React components that can be found in the package @lumieducation/h5p-react. The React components wrap around the web components from @lumieducation/h5p-webcomponents, which in turn wrap the actual core h5p player and editor JavaScript and simplify instantiation, loading, saving and event handling.

• The blue parts is comprised of JavaScript and CSS files that make up the core H5P player and editor. They are part of the original PHP repositories and are downloaded from GitHub in the server with the script download-core.sh. They must be served as static files by the server and are added to the page by the web components as needed.

Trying it out

1. Clone the repository

2. Run npm install in the root. This will install all dependencies of the example packages and internally link the packages inside the monorepo with symlinks (lerna).

3. Run npm start for the server. (Must be up and running before you start the client!)

4. Run npm start for the client (the server must still be running).

5. A browser should open on http://localhost:3000. If there is an error, you have to reload the the page, as the server might not be fully initialized yet.

Client

The client was bootstrapped with Create React App. For more information see its documentation page.
