Also the modular packages they have built are amazing. They have a node package called @jupyterlab/services which lets you write typescript code for your own libraries that can then call the Jupyter Server. An example of using JupyterLab services is provided on their GitHub: https://github.com/jupyterlab/jupyterlab/tree/master/packages/services/examples/typescript-browser-with-output https://github.com/jupyterlab/jupyterlab/tree/master/package... Because of the way they built their packages I have been able to stand on the shoulder of giants and build the following tool: https://github.com/SimonBiggs/scriptedforms https://github.com/SimonBiggs/scriptedforms I am very grateful to the JupyterLab team. They have built something brilliant.
