🪐 ⚛️ Jupyter React Example

Example to showcase Jupyter React usage in a Create React application.

This repository is archived and only covers Jupyter React up-to version 0.0.10. Please go to the main Jupyter React repository for updated examples.

Environment

Follow the below steps to create your development environment. You will need Miniconda up-and-running on your machine (MacOS or Linux, Windows is not supported as development platform for the time-being).

# Clone the jupyter-react-example repository.
git clone https://github.com/datalayer/jupyter-react-example.git && \
  cd jupyter-react-example
# Setup your development environment.
conda deactivate && \
  make env-rm # If you want to reset your environment.
make env && \
  conda activate jupyter-react
# Install.
make install
# You can start the example and hack the source code.
# The changes will build automatically and will be available in your browser.
echo open http://localhost:3000
yarn start

Create your own create-react-app (version 5)

You can create your own app and add the Datalayer Jupyter React dependency.

npx create-react-app jupyter-react-example --template typescript && \
  cd jupyter-react-example && \
  yarn add @datalayer/jupyter-react

Once this is done, double-check the following requirements (just checkout this repository for a complete setup).

Startup Scripts

You will need a Jupyter server up-and-running. We ship the configuration and scripts in this repository. You can add in your package.json the needed definitions.

  "scripts": {
    "start": "run-p -c start:*",
    "start:jupyter": "make start-jupyter-server",
    "start:react": "react-scripts start",
  },
  "devDependencies": {
    "npm-run-all": "4.1.5",
  },

Dot Env

It looks like the create-react-app version 5 does not like sourcemaps pointing to non existing source code. To avoid error messages, please create a .env file at the top of your folder/repositoriy and add there GENERATE_SOURCEMAP=false.

// .env
GENERATE_SOURCEMAP=false

Metadata in index.html

You need to add in the public/index.html the needed information to indicate where you Jupyter server is running.

    <script id="datalayer-config-data" type="application/json">
      {
        "jupyterServerHttpUrl": "http://localhost:8686/api/jupyter",
        "jupyterServerWsUrl": "ws://localhost:8686/api/jupyter",
        "jupyterToken": "60c1661cc408f978c309d04157af55c9588ff9557c9380e4fb50785750703da6"
      }
    </script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.4/require.min.js"></script>

React.js version resolutions

A create-react-app requests coherent react.js versions. With JupyterLab, we are pulling various version in the node_modules subfolders. To avoid version conflicts, the resolutions in package.json specifies the needed version.

Fix JupyterLab dependency definitions

Run make install. This will apply the following temporary patch on the JupyterLab dependency type definitions.

echo "The following is a temporary fix tested on MacOS - For other OS, you may need to fix manually"
sed -i.bu "s|k: keyof TableOfContents.IConfig|k: string|g" node_modules/\@jupyterlab/notebook/lib/toc.d.ts
sed -i.bu "s|uri: DocumentUri|uri: string|g" node_modules/vscode-languageserver-protocol/lib/common/protocol.diagnostic.d.ts
sed -i.bu "s|uri: DocumentUri|uri: string|g" node_modules/vscode-languageserver-types/lib/umd/main.d.ts
sed -i.bu "s|id: ChangeAnnotationIdentifier|uri: string|g" node_modules/vscode-languageserver-types/lib/umd/main.d.ts
