@vscode/jupyter-ipywidgets

1.0.9 • Public • Published

This folder is based off the the sample web3 from https://github.com/jupyter-widgets/ipywidgets/blob/master/examples/web3

  • We have built a custom solution based on web3 sample to host ipywidgets outside of Jupyter Notebook.

Warning

  • Most of the code has been copied as is from https://github.com/jupyter-widgets/ipywidgets/blob/master/examples/web3 & https://github.com/jupyter-widgets/ipywidgets/blob/master/packages/html-manager/webpack.config.js.
    • Please try to minimize changes to original code to facilitate easier updatess.

Solution for IPywidgets

  • IPywidgets traditionally use requirejs.
    • traditionally as there seems to be some ongoing work to use commonjs2, though unsure how this will work with 3rd party widgets.
  • Using 3rd party widgets require:
    • requirejs to be available in the current browser context (i.e. window)
    • Base IPywidgets to be defined using define in requirejs.
  • Rather than bundling using amd or umd its easier to just import everything using commonjs2, then export for requirejs using define by hand.
    • define('xyz', () => 'a') is a simple way of declaring a named xyz module with the value a (using requirejs).
    • This is generally done using tools, however we'll hand craft this as it works better and easier.
    • amd is not what we want, as out react ui doesn't use amd.
    • umd is does not work as we have multiple entry points in webpack.
    • Heres' the solution define('@jupyter-widgets/controls', () => widgets);
  • We bundling the widget controls into our JS and exposing them for AMD using define
    • We could instead include https://unpkg.com/browse/@jupyter-widgets/html-manager@0.18.3/dist/embed-amd.js
    • However this is a 3.2MB file.
    • Then our Widget manager also needs the widget controls. That would mean widget controls get included twice, once in our bundle and the other in the above mentioned embed-amd.js file.
    • Solution is to include everything thats in embed-amd.js into our bundle.
  • We need types for requirejs, but installing this into node_modules, for extension causes conflicts as we use require in standard node (extension and UI).
    • Solution is to just copy the @types/requirejs/index.d.ts into the types folder.

Directions for building

You might want to setup an npm link for the python repository

Then to build vscode-jupyter-ipywidgets

  • npm run download-api (updates vscode.d.ts)
  • npm run webpack (which will setup stuff for using with vscode-python)

Directions for debugging with jupyter extension

  • Run the steps above for getting the npm link setup
  • From with VS code, open both jupyter and lsp-middleware as two folders
  • Build the 'webpack link' task for lsp-middleware
  • Build the compile task for jupyter
  • Set breakpoints in the dist/node/index.js file while debugging (it's a development webpack)
  • Edit lsp code
  • Rerun the 'webpack link' build every time (it doesn't watch as it runs a post build step)
