This is the repository for the KBase Narrative Interface.

About

The KBase Narrative Interface builds on the Jupyter Notebook and contains elements to interact with various KBase tools and data stores.

This document contains links to various documentation in the docs directory, with a brief description of each.

Local Installation (for developers)

Short version:
Requires the following:

  • Python 2.7+ (working on updating to Python 3...)
  • Node.js v6 LTS (needed for npm)
  • Bower
git clone https://github.com/kbase/narrative
cd narrative
./scripts/install_narrative.sh -v narr-venv
source narr-venv/bin/activate
kbase-narrative

Long version:

Local Narrative setup/deployment

Server installation (for administrators)

If you want to set up your own Narrative server that uses the Docker framework, the below document will walk you through it. Once the server is set up, you only need to pull new code and build a new Docker image from it. You can also pull Narrative images directly from Dockerhub in the KBase namespace.

The document specifically describes how you would build the system on a Vagrant image, but is applicable to any Ubuntu-based system.

Architecture

In progress!

The Narrative sits on top of the Jupyter Notebook, so most of its architecture is a mirror of that. However, the Narrative's interaction with other KBase elements - namely the data stores and job running services - merits its own description. This will be ongoing (and evolving!), but a brief description of how a job gets run and registered is available here:

Narrative App/Method Running

When deployed in production, the Narrative Interface is compiled into a Docker container. When a user logs in, they have their own instance provisioned for them through an Nginx proxy, which provides a temporary server-side Narrative environment only for that user. Any changes made to a Narrative get saved as part of KBase data stores, but any changes to the file system or the Narrative kernel (e.g. local variables) are lost when the user logs out and their Docker instance gets shut down.

Testing

Testing is composed of three components:

  • a make test directive that runs through a batch of unit-testing of the Narrative, both the front-end Javascript-based components, and the back-end IPython modifications
  • a travis.yml file for Travis-CI testing
  • a set of Selenium-based end-to-end tests that simulate browser interactions

Testing locally (i.e. not through Travis-CI) requires a local Narrative installation, with active virtualenv (if installed that way). Then just run make test or make test-frontend-unit or make test-backend

Submitting code

We currently use a modified version of the famous Git flow workflow, described below:

Narrative Git Workflow

The short version is this - all development work is done on the develop branch. After some stability occurs, this gets merged to staging for internal testing, then to master where it is tagged and released to production.

So when you want to submit code, please make a pull request against develop.
