Web app for visualizing pathogen evolution

Master: Build Status Release: Build Status npm: NPM version


Auspice is an open-source interactive web app for visualising phylogenomic data. It is the app that powers all the vlisualisation on nextstrain.org, which aims to provide a continually-updated view of publicly available pathogen genome data. Auspice was designed to aid epidemiological understanding and improve outbreak response, but is able to visualise a diverse range of datasets.

Please see nextstrain.org/docs/visualisation/introduction for more information, including input file formats.


npm install -g auspice

Note that this requires node and npm to be installed (see below for instructions).

Running Auspice

auspice starts the server, which makes local datasets available in a browser at localhost:4000/local.

By default, the datasets are sourced from the current working directory (or an auspice subfolder if it exists). Please run auspice -h to see how to change this directory, as well as the directory where narratives are sourced from.


Development requires installation by cloning the github repo:

cd nextstrain # or whichever folder you'd like to contain nextstrain repos in
git clone https://github.com/nextstrain/auspice.git
cd auspice
npm install     # install package dependencies
npm run dev     # start the server (with hot-reloading)

Then access the app via localhost:4000/local. Changes to the (client) code should automatically update the browser.

By default, datasets and narratives are sourced out of the auspice/data and auspice/local_narratives directories. Running npm run dev -- -h shows the available options to change these defaults.

To build the production code (which is what the live site and global npm install use), run npm run build to transpile the client code, and npm run server to start the server.

How to install Node.js and npm

If you are comfortable using conda, installing nodejs is as simple as conda install -c conda-forge nodejs=9.11.1. If you'd prefer not to use conda, nvm is an easy way to manage nodejs & npm versions -- this guide walks you through the installation.

Releasing new versions.

You will need push access to github.com/nextstrain/auspice, and local master must be up-to-date. Releasing should then be as simple as running ./releaseNewVersion and following the prompts.

Deploying to npm

This should be handled automatically when releases happen (assuming that the TravisCI build passes). To do this manually: * ensure your npm account is registered with npmjs.com/package/auspice * build the bundle.js via npm run build * ensure the version number (node server.js --version) is different to npmjs.com/package/auspice * npm publish
