Fileglancer frontend extension

React-based frontend extension for the Fileglancer app.

Development install

Clone the repo to your local environment and change directory to the new repo folder.

git clone [e-mail]:JaneliaSciComp/fileglancer.git
cd fileglancer

If this is your first time installing the extension in dev mode, install package in development mode.

pixi run dev-install

You can build the frontend extension in watch mode - it will automatically rebuild when there are file changes to the frontend:

pixi run dev-watch

In new terminal, run JupyterLab in autoreload mode - it will automatically rebuild when there are file changes to the backend:

pixi run dev-launch

Saved changes in your directory should now be automatically built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).

If everything has worked so far, you should see the Fileglancer widget on the Launcher pane:

Troubleshooting the extension

If you run into any build issues, the first thing to try is to clear the build directories and start from scratch:

./clean.sh

If you're still having issues, try manually deleting the symlink at .pixi/envs/share/jupyter/labextensions/fileglancer inside the fileglancer repo directory. Then, reinstall the extension using pixi run dev-install, and follow the steps above from there.

Configuration

By default, no Fileglancer Central server will be used. You can configure the URL of a Fileglancer Central server with traitlets, in several ways:

Command line

pixi run dev-launch --Fileglancer.central_url=http://0.0.0.0:7878

Config file

You can create a file at ~/.jupyter/jupyter_server_config.py (or in any of the paths reported by pixi run jupyter --paths) and add your configuration there, e.g.:

c.Fileglancer.central_url='http://0.0.0.0:7878'

Development Uninstall

pixi run pip-uninstall

In development mode, you will also need to remove the symlink created by jupyter labextension develop command. To find its location, you can run jupyter labextension list to figure out where the labextensions folder is located. Then you can remove the symlink named fileglancer within that folder.

Testing

Backend tests

To run backend tests using pytest:

pixi run test-backend

Frontend unit tests

This extension is using Vitest for JavaScript code testing.

To execute the unit tests:

pixi run test-frontend

Integration tests

This extension uses Playwright for the integration tests (aka user level tests). More precisely, the JupyterLab helper Galata is used to handle testing the extension in JupyterLab. More information are provided within the ui-tests README.

To execute the UI integration test, run:

pixi run ui-test

You can also run these in UI debug mode using:

pixi run ui-test -- --ui --debug

If you are unable to use the UI mode, record a trace for inspecting in the Playwright trace viewer:

pixi run ui-test -- --trace on

To run only a specific test:

pixi run ui-test -- --<optional-flag> tests/fgzones.spec.ts

You can also use the name of the test:

pixi run ui-test -- -g "the test description"
