API Endpoint: API
- Rvm, ruby, bundler
- Sqlite on development and Postgresql on production
- ElasticSearch to store search metadata
You need to clone repo, run
bundle install
rake db:migrate
rake parsers:milkyway:all
rake search:rebuild
The rake parser:milkyway:all
rake task fetches the DU data set from http://research.amnh.org/users/abbott/dudata/ and stores it into Postgres.
The rake search:rebuild
builds search index for all these data sets.
- Available resources as REST get api: stars, exo_planets, local_groups, open clusters, constellations
- Paginated queries
- Search endpoint at
/api/v1/search?q=<search query>
to search for all available names and labels - Filter queries like
/api/v1/stars?min[distl]=10&max[distl]=20
finds all stars whose distl values are between 10 and 20. Its applicable to any comparable field available in response data of a particular resource
- Run this query to filter only blue stars:
http://star-api.herokuapp.com/api/v1/stars?min[colorb_v]=-1&max[colorb_v]=0 - To see only red stars: http://star-api.herokuapp.com/api/v1/stars?min[colorb_v]=0&max[colorb_v]=1
- To filter stars you can see with the naked yield: http://star-api.herokuapp.com/api/v1/stars?min[appmag]=-2.5&max[appmag]=6.5
- To see stars brighter than 7.5 mag: http://star-api.herokuapp.com/api/v1/stars?max[appmag]=7.5
- To see only the trig parallax stars: http://star-api.herokuapp.com/api/v1/stars?dcalc=1
- To see only the weighted mean stars: http://star-api.herokuapp.com/api/v1/stars?dcalc=2
- To see all the intrinsically bright stars: http://star-api.herokuapp.com/api/v1/stars?min[absmag]=10&max[absmag]=-3
- To see all the intrinsically faint stars: http://star-api.herokuapp.com/api/v1/stars?min[absmag]=0&max[absmag]=-3
- To see all stars within 100 light-years: http://star-api.herokuapp.com/api/v1/stars?max[distly]=100
- To see all stars within 500 light-years: http://star-api.herokuapp.com/api/v1/stars?max[distly]=500
