Catching Jupyter-specific bugs before CI does: announcing jupyter eslint plugin

We’re excited to announce the release of the first version of the Jupyter ESLint plugin @jupyter/eslint-plugin , now available on npm. It’s a custom ESLint plugin designed specifically for the official Jupyter frontends (JupyterLab, Notebook, JupyterLite) and TypeScript extensions built around them. Motivation If you’ve ever written a JupyterLab extension, you’ve probably hit something like this: You wire up a new plugin, push a PR, walk away to make coffee, and 30 minutes later CI fails on a test you didn’t expect to be related.
