Jupyter Notebook Viewer
Run this locally to get most of the features of nbviewer on your own network.
If you have
docker installed, you can pull and run the currently built version of the Docker container by
$ docker pull jupyter/nbviewer $ docker run -p 8080:8080 jupyter/nbviewer
It automatically gets built with each push to
master, so you'll always be able to get the freshest copy.
For speed and friendliness to GitHub, be sure to set
$ docker run -p 8080:8080 -e 'GITHUB_OAUTH_KEY=YOURKEY' \ -e 'GITHUB_OAUTH_SECRET=YOURSECRET' \ jupyter/nbviewer
Or to use your GitHub personal access token, you can set just
To use nbviewer on against your own GitHub Enterprise instance you need to set
The relevant API endpoints for GitHub Enterprise are prefixed with
You must also specify your
API_TOKEN as explained above. For example:
$ docker run -p 8080:8080 -e 'GITHUB_OAUTH_KEY=YOURKEY' \ -e 'GITHUB_OAUTH_SECRET=YOURSECRET' \ -e 'GITHUB_API_URL=https://ghe.example.com/api/v3/' \ jupyter/nbviewer
With this configured all GitHub API requests will go to your Enterprise instance so you can view all of your internal notebooks.
You can build a docker image that uses your local branch.
$ cd <path to repo> $ docker build -t nbviewer .
$ cd <path to repo> $ docker run -p 8080:8080 nbviewer
With Docker Compose
The Notebook Viewer uses
memcached in production. To locally try out this
setup, a docker-compose configuration is
provided to easily start/stop the
together from a your current branch. You will need to install
$ cd <path to repo> $ pip install docker-compose $ docker-compose up
The Notebook Viewer requires several binary packages to be installed on your system. The primary ones are
libmemcached-dev libcurl4-openssl-dev pandoc libevent-dev. Package names may differ on your system, see salt-states for more details.
If they are installed, you can install the required Python packages via pip.
$ cd <path to repo> $ pip install -r requirements.txt
Static assets are maintained with
less (which require having
npm installed), and the
invoke python module.
$ cd <path to repo> $ pip install -r requirements-dev.txt $ npm install $ invoke bower $ invoke less [-d]
This will download the relevant assets into
nbviewer/static/components and create the built assets in
invoke less to create a CSS sourcemap, useful for debugging.
$ cd <path to repo> $ python -m nbviewer --debug --no-cache
This will automatically relaunch the server if a change is detected on a python file, and not cache any results. You can then just do the modifications you like to the source code and/or the templates then refresh the pages.
Running the Tests
nose is used to run the test suite. The tests currently make calls to
external APIs such as GitHub, so it is best to use your Github API Token when
$ cd <path to repo> $ pip install -r requirements-dev.txt $ GITHUB_API_TOKEN=<your token> python setup.py test
Extending the Notebook Viewer
Providers are sources of notebooks and directories of notebooks and directories.
nbviewer ships with several providers
Writing a new Provider
There are several already additional providers proposed/requested. Some providers are more involved than others, and some, such as those which would require user authentication, will take some work to support properly.
A provider is implemented as a python module, which can expose a few functions:
If you just need to rewrite URLs (or URIs) of another site/namespace, implement
uri_rewrites, which will allow the front page to transform an arbitrary string
(usually an URI fragment), escape it correctly, and turn it into a "canonical"
nbviewer URL. See the dropbox provider
for a simple example of rewriting URLs without using a custom API client.
If you need custom logic, such as connecting to an API, implement
default_handlers. See the github provider
for a complex example of providing multiple handlers.
While you could re-implement upstream HTTP error handling, a small
convenience method is provided for intercepting HTTP errors.
On a given URL handler that inherits from
BaseHandler, overload the
client_error_message and re-call it with your message (or
None). See the
gist provider for an example of customizing the
Formats are ways to present notebooks to the user.
nbviewer ships with two providers:
