EarthWorks

Geospatial discovery application for Stanford University Libraries, built using GeoBlacklight.

Developing

For the currently supported Ruby version, see the .github/workflows/ruby.yml file.

Installing

Pull down the code:

git clone git@github.com:sul-dlss/earthworks.git

Run the supporting services

You can do this by either running them directly on your dev machine, or by running them in containers using Docker (you should choose one or the other)

Running supporting services directly

Start an Apache Solr instance using solr_wrapper:

solr_wrapper

Running supporting services using Docker

A more production-like setup using Redis and Postgresql is available via Docker. To start the stack:

docker compose up

To have the app use the Postresql container instead of SQLite, uncomment the DATABASE_URL line in the .env[.test] file(s) (in the project root).

To have the app use the Redis container, uncomment the REDIS_URL, REDIS_HOST, and REDIS_PORT lines in the .env[.test] file(s).

The Solr connection info is the same regardless of whether it's run using solr_wrapper or Docker.

Alternatively, you could specify those env vars by prefixing the rails command with them, to (for example) run the app once using Postgres while generally defaulting to SQLite (e.g. DATABASE_URL='postgresql://earthworks:earthworks@localhost/earthworks?pool=5' bin/rails server).

Install the Ruby and Javascript dependencies, and prepare the database

Next, run the setup script:

bin/setup

Run the application

Finally, start the development web server:

bin/dev

This will compile the SCSS stylesheets with live reloading in addition to running a rails server.

Adding data

To add a small amount of test records to the Solr index, you can use the seed task:

bin/rake earthworks:fixtures

To index arbitary data from SDR, see the searchworks_traject_indexer README.

You can also fetch non-Stanford records from OpenGeoMetadata using GeoCombine:

export OGM_PATH=tmp/opengeometadata     # location to store data
bin/rake geocombine:clone[edu.nyu]      # pull data from NYU
bin/rake geocombine:index               # index data in Solr

Testing

You can run the full suite of tests with the ci command. Do not run this while ssh tunneled as it may delete the production index!

bin/rake ci
