Pull Requests for JupyterLab

Project description


Build Status NPM Version Pypi Version Conda Version

A JupyterLab extension for reviewing pull requests.


For now, it supports GitHub and GitLab providers.


For GitLab, you will need also diff-match-patch


  • Open the pull request extension from the tab on the left panel


1. Install the extension with the following steps

With pip:

pip install jupyterlab-pullrequests

Or with conda:

conda install -c conda-forge jupyterlab-pullrequests

For GitLab, in addition, you will need to

pip install diff-match-patch

Or with conda:

conda install -c conda-forge diff-match-patch

2. Getting your access token

For GitHub, the documentation is there. The token scope must be repo.

For GitLab, the documentation is there. The token scope must be api.

Remember that this token is effectively a password for your account. Do not share it online or check the token into version control, as people can use it to access all of your data.

3. Setting your access token in JupyterLab Pull Requests

You now need to add the credentials you got from the provider to your server configuration file. Instructions for generating a configuration file can be found here. Once you have identified this file, add the following lines to it:

c.PRConfig.access_token = '<YOUR_ACCESS_TOKEN>'

where "<YOUR_ACCESS_TOKEN>" is the string value you obtained above.

If you are using GitLab instead of GitHub, you also need to set the provider:

c.PRConfig.provider = 'gitlab'

Congrats, you did it! Launch JupyterLab and look for the Pull Request tab on the left! 🎉

If you are not using or, you can set the API base URL of your provider with the configurable parameter PRConfig.api_base_url.


This extension as server settings.

  • PRConfig.access_token: Access token to be authenticated by the provider
  • PRConfig.provider: github (default) or gitlab
  • PRConfig.api_base_url: Provider API base url (default to except if provider is gitlab then it defaults to


  • If you are seeing the following error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain and the certificates are installed on your machine, you will need to set the SSL_CERT_FILE environment variable to point to your system certificates bundle. For example:
export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
