Getting Started

The easiest way to get started with TerriaJS is to use TerriaMap. TerriaMap is a full-featured application built on TerriaJS, ready to be customized with your own branding and catalog. It is also a great starting point for more in-depth customization.

This guide explains how to build and run TerriaMap locally. See Deployment to learn how to deploy it for use by others.

Quick Start

If you've done this sort of thing before, you'll find it easy to clone and build TerriaMap with these quick instructions:

git clone

cd TerriaMap

npm install && npm run gulp && npm start

# Open at http://localhost:3001

If you run into trouble or want more explanation, read on.


TerriaJS can be built and run on almost any macOS, Linux, or Windows system. The following are required to build TerriaJS:

  • Node.js v5.10 or later. v6.x and v7.x are also known to work, and later major versions are likely to work as well. You can check your node version by running node --version on the command-line.
  • npm v3.0 or later. This is usually installed automatically alongside the above. You can check your npm version by running npm --version.

The following components are optional:

  • GDAL - Used for the conversion service that transforms Esri Shapefiles and other more obscure formats into GeoJSON for display in TerriaJS. This is not required for formats that TerriaJS supports directly, including KML, GeoJSON, etc.

Cloning TerriaMap

The latest version of TerriaMap is on GitHub, and the preferred way to get it is by using git:

git clone

cd TerriaMap

If you're unable to use git, you can also download a ZIP file and extract it somewhere on your system. We recommend using git, though, because it makes it much easier to update to later versions in the future.

Installing Dependencies

All of the dependencies required to build and run TerriaMap, other than the prerequisites listed above, are installed using npm:

npm install

The dependencies are installed in the node_modules subdirectory. No global changes are made to your system.

Building TerriaMap

Do a standard build of TerriaMap with:

npm run gulp

Or, you can create a minified release build with:

npm run gulp release

To watch for changes and automatically do an incremental build when any are detected, use:

npm run gulp watch

npm run gulp simply runs gulp, so you can use that directly if you prefer (run npm install -g gulp to install it globally).

The full set of gulp tasks can be found on the Development Environment page.

Running TerriaMap

TerriaMap includes a simple Node.js-based web server, called terriajs-server. To start it, run:

npm start

Then, open a web browser on http://localhost:3001 to use TerriaMap.

Keeping up with Updates

If you're building an application by using TerriaMap as a starting point, you will want to keep in sync as TerriaMap is improved and updated to use new versions of TerriaJS. Forking the TerriaMap repo and using git to keep it in sync is outside the scope of this document, but GitHub has a nice explanation.

After pulling new changes, you will need to run npm install again to pick up any changed dependencies and then build TerriaMap. If you have problems building or running, it is sometimes helpful to remove and reinstall the dependencies from npm:

rm -rf node_modules
npm install

Next Steps

Now that you have a working local build of TerriaMap, you may want to customize it or deploy it for others to use.
