-# Jupyter AI Module Cookiecutter
-
-A [cookiecutter](https://github.com/audreyr/cookiecutter) template for creating
-a AI module. The AI module constructed from the template serves as a very simple
-example that can be extended however you wish.
-
-## Usage
-
-Install cookiecutter.
-
-```
-pip install cookiecutter
-```
-
-Then from the project root, run these commands:
-
-```
-cd packages/
-cookiecutter jupyter-ai-module-cookiecutter
-```
-
-Follow the prompts to create a new AI module under `packages/`. Your
-labextension name should use hyphens, whereas your Python name should use
-underscores.
-
-# Usage (monorepo integration)
-
-To integrate the new AI module into this monorepo, execute this command
-manually from the AI module root:
-
-```
-rm -r .github/ binder/ CHANGELOG.md RELEASE.md
-```
-
-Rename the JS package to be scoped under `@jupyter-ai/`.
-
-Finally, add the Python package to the `options.python_packages` field in
-`.jupyter-releaser.toml`.

-# {{ cookiecutter.python_name }}
-
-This extension is composed of a Python package named `{{ cookiecutter.python_name }}`
-that exposes the model engines to the Jupyter AI server extension,
-and an NPM package named `{{ cookiecutter.labextension_name }}`
-that provides a frontend labextension registering inserters.
-
-## Requirements
-
-- Python 3.8 - 3.11
-- JupyterLab 4
-
-## Install
-
-To install the extension, execute:
-
-```bash
-pip install {{ cookiecutter.python_name }}
-```
-
-## Uninstall
-
-To remove the extension, execute:
-
-```bash
-pip uninstall {{ cookiecutter.python_name }}
-```
-## Contributing
-
-### Development install
-
-Note: You will need NodeJS to build the extension package.
-
-The `jlpm` command is JupyterLab's pinned version of
-[yarn](https://yarnpkg.com/) that is installed with JupyterLab. You may use
-`yarn` or `npm` in lieu of `jlpm` below.
-
-```bash
-# Clone the repo to your local environment
-# Change directory to the {{ cookiecutter.python_name }} directory
-# Install package in development mode
-pip install -e ".{% if cookiecutter.test.lower().startswith('y') %}[test]{% endif %}"
-# Link your development version of the extension with JupyterLab
-jupyter labextension develop . --overwrite
-# Rebuild extension Typescript source after making changes
-jlpm build
-```
-
-You can watch the source directory and run JupyterLab at the same time in
-different terminals to watch for changes in the extension's source and
-automatically rebuild the extension.
-
-```bash
-# Watch the source directory in one terminal, automatically rebuilding when needed
-jlpm watch
-# Run JupyterLab in another terminal
-jupyter lab
-```
-
-With the watch command running, every saved change will immediately be 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).
-
-By default, the `jlpm build` command generates the source maps for this
-extension to make it easier to debug using the browser dev tools. To also
-generate source maps for the JupyterLab core extensions, you can run the
-following command:
-
-```bash
-jupyter lab build --minimize=False
-```
-
-### Development uninstall
-
-```bash
-pip uninstall {{ cookiecutter.python_name }}
-```
-
-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 `{{ cookiecutter.labextension_name }}` within that folder.
-{% if cookiecutter.test.lower().startswith('y') %}
-### Testing the extension
-
-#### Backend tests
-
-This AI module is using [Pytest](https://docs.pytest.org/) for Python code testing.
-
-Install test dependencies (needed only once):
-
-```sh
-pip install -e ".[test]"
-# Each time you install the Python package, you need to restore the front-end extension link
-jupyter labextension develop . --overwrite
-```
-
-To execute them, run:
-
-```sh
-pytest -vv -r ap --cov {{ cookiecutter.python_name }}
-```
-
-#### Frontend tests
-
-This extension is using [Jest](https://jestjs.io/) for JavaScript code testing.
-
-To execute them, execute:
-
-```sh
-jlpm
-jlpm test
-```
-
-#### Integration tests
-
-This extension uses [Playwright](https://playwright.dev/docs/intro/) for the integration tests (aka user level tests).
-More precisely, the JupyterLab helper [Galata](https://github.com/jupyterlab/jupyterlab/tree/master/galata) is used to handle testing the extension in JupyterLab.
-
-More information are provided within the [ui-tests](./ui-tests/README.md) README.

-# Making a new release of {{ cookiecutter.python_name }}
-
-The extension can be published to `PyPI` and `npm` manually or using the [Jupyter Releaser](https://github.com/jupyter-server/jupyter_releaser).
-
-## Manual release
-
-### Python package
-
-This extension can be distributed as Python
-packages. All of the Python
-packaging instructions in the `pyproject.toml` file to wrap your extension in a
-Python package. Before generating a package, we first need to install `build`.
-
-```bash
-pip install build twine hatch
-```
-
-Bump the version using `hatch`. By default this will create a tag.
-See the docs on [hatch-nodejs-version](https://github.com/agoose77/hatch-nodejs-version#semver) for details.
-
-```bash
-hatch version <new-version>
-```
-
-To create a Python source package (`.tar.gz`) and the binary package (`.whl`) in the `dist/` directory, do:
-
-```bash
-python -m build
-```
-
-> `python setup.py sdist bdist_wheel` is deprecated and will not work for this package.
-
-Then to upload the package to PyPI, do:
-
-```bash
-twine upload dist/*
-```
-
-### NPM package
-
-To publish the frontend part of the extension as a NPM package, do:
-
-```bash
-npm login
-npm publish --access public
-```
-
-## Automated releases with the Jupyter Releaser
-
-The extension repository should already be compatible with the Jupyter Releaser.
-
-Check out the [workflow documentation](https://github.com/jupyter-server/jupyter_releaser#typical-workflow) for more information.
-
-Here is a summary of the steps to cut a new release:
-
-- Fork the [`jupyter-releaser` repo](https://github.com/jupyter-server/jupyter_releaser)
-- Add `ADMIN_GITHUB_TOKEN`, `PYPI_TOKEN` and `NPM_TOKEN` to the Github Secrets in the fork
-- Go to the Actions panel
-- Run the "Draft Changelog" workflow
-- Merge the Changelog PR
-- Run the "Draft Release" workflow
-- Run the "Publish Release" workflow
-
-## Publishing to `conda-forge`
-
-If the package is not on conda forge yet, check the documentation to learn how to add it: https://conda-forge.org/docs/maintainer/adding_pkgs.html
-
-Otherwise a bot should pick up the new version publish to PyPI, and open a new PR on the feedstock repository automatically.

-# Integration Testing
-
-This folder contains the integration tests of the extension.
-
-They are defined using [Playwright](https://playwright.dev/docs/intro) test runner
-and [Galata](https://github.com/jupyterlab/jupyterlab/tree/master/galata) helper.
-
-The Playwright configuration is defined in [playwright.config.js](./playwright.config.js).
-
-The JupyterLab server configuration to use for the integration test is defined
-in [jupyter_server_test_config.py](./jupyter_server_test_config.py).
-
-The default configuration will produce video for failing tests and an HTML report.
-
-## Run the tests
-
-> All commands are assumed to be executed from the root directory
-
-To run the tests, you need to:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the [Playwright](https://playwright.dev/docs/intro) tests:
-
-```sh
-cd ./ui-tests
-jlpm playwright test
-```
-
-Test results will be shown in the terminal. In case of any test failures, the test report
-will be opened in your browser at the end of the tests execution; see
-[Playwright documentation](https://playwright.dev/docs/test-reporters#html-reporter)
-for configuring that behavior.
-
-## Update the tests snapshots
-
-> All commands are assumed to be executed from the root directory
-
-If you are comparing snapshots to validate your tests, you may need to update
-the reference snapshots stored in the repository. To do that, you need to:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the [Playwright](https://playwright.dev/docs/intro) command:
-
-```sh
-cd ./ui-tests
-jlpm playwright test -u
-```
-
-> Some discrepancy may occurs between the snapshots generated on your computer and
-> the one generated on the CI. To ease updating the snapshots on a PR, you can
-> type `please update playwright snapshots` to trigger the update by a bot on the CI.
-> Once the bot has computed new snapshots, it will commit them to the PR branch.
-
-## Create tests
-
-> All commands are assumed to be executed from the root directory
-
-To create tests, the easiest way is to use the code generator tool of playwright:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the [Playwright code generator](https://playwright.dev/docs/codegen):
-
-```sh
-cd ./ui-tests
-jlpm playwright codegen localhost:8888
-```
-
-## Debug tests
-
-> All commands are assumed to be executed from the root directory
-
-To debug tests, a good way is to use the inspector tool of playwright:
-
-1. Compile the extension:
-
-```sh
-jlpm install
-jlpm build:prod
-```
-
-> Check the extension is installed in JupyterLab.
-
-2. Install test dependencies (needed only once):
-
-```sh
-cd ./ui-tests
-jlpm install
-jlpm playwright install
-cd ..
-```
-
-3. Execute the Playwright tests in [debug mode](https://playwright.dev/docs/debug):
-
-```sh
-cd ./ui-tests
-PWDEBUG=1 jlpm playwright test
-```
