COVID-19 Dashboard

As communities around the world have changed their behavior in response to the spread of COVID-19, NASA satellites have observed changes in the environment. This experimental dashboard reflects a rapid response to COVID-19 that is currently underway and will continue to evolve as more data becomes available.

This dashboard is powered by an open source API that is developed in parallel. This API focuses on serving the Cloud Optimized GeoTIFF and time-series indicator data that people can interact with in the dashboard.

Installation and Usage

The steps below will walk you through setting up your own instance of the project.

Install Project Dependencies

To set up the development environment for this website, you'll need to install the following on your system:

• Node v12 (To manage multiple node versions we recommend nvm)
• Yarn Package manager

Install Application Dependencies

If you use nvm, activate the desired Node version:

nvm install

Install Node modules:

Usage

Config files

All the config files can be found in app/assets/scripts/config. After installing the projects there will be 3 main files:

• local.js - Used only for local development. On production this file should not exist or be empty.
• staging.js
• production.js

The production.js file serves as base and the other 2 will override it as needed:

• staging.js will be loaded whenever the env variable DS_ENV is set to staging.
• local.js will be loaded if it exists.

The following options must be set: (The used file will depend on the context):

• value - Description

Example:

module.exports = {
  value: 'some-value'
};

To be able to use the app you will need a mapbox token.
Once obtained add it to the app/assets/scripts/config/local.js file, under the mbToken key.

Starting the app

yarn serve

Compiles the sass files, javascript, and launches the server making the site available at http://localhost:9000/ The system will watch files and execute tasks whenever one of them changes. The site will automatically refresh since it is bundled with livereload.

Deployment

To prepare the app for deployment run:

yarn build

or

yarn stage

This will package the app and place all the contents in the dist directory. The app can then be run by any web server.

When building the site for deployment provide the base url trough the BASEURL environment variable. Omit the leading slash. (E.g. https://example.com)
