Final project for IEMS 201.
Runs persistently in the background to collect information from the CTA Train Tracker API for a certain station. At specified intervals, compares the API output to the previous API output to infer if trains have departed from the station between API calls. If so, records of departures are pushed to a database.
Database implementation is currently MySQL but the interface allows for this to be expanded to other providers. See src/DB.ts for interface details.
| Variable Name | Value |
|---|---|
| CTA_API_KEY | API key for the CTA Train Tracker API. Obtainable here. |
| CTA_STATION | Station ID for the station to be monitored. From this list. |
| API_ROOT | Should be http://lapi.transitchicago.com/api/1.0 unless mocking. |
MYSQL_USERNAME, MYSQL_PASSWORD, MYSQL_HOST, MYSQL_PORT, and MYSQL_DATABASE should all be self-explanatory. All are optional except MYSQL_DATABASE and MYSQL_USERNAME.
Clone the repository and run npm install. Set up your environment as per above. If you're using MySQL, you can use the included db/setup.sql file to set up your server
with a database and test database (iems, iems_test) and a user for each (iems, iems-test).
Run npm-test.
