A Node.js API for Chicago's Divvy bikesharing service

To run

1. npm install
2. npm start

Note: The server takes 30 seconds to initialize as it retrieves the trip data, parses it and fills the dictionary data structure we will access. Wait until you see Server listening on port 3000 in the console before sending requests.

To test

1. npm test

Authentication

You need to get your API token before accessing any endpoints.

1. Call http://localhost:3000/auth/token in Postman and copy the value of the token field.

2. Go to the Headers tab in Postman and add Authorization as a header key and Bearer <your token here> as the value.

3. Without your token, you will get a 403 Forbidden response from the server.

Endpoints

1. Get a bike station's info by its ID

• Each station has an ID from 2 - 673, though not all values are valid IDs.
• Send a GET request to http://localhost:3000/station/:id where :id is a number within the stated range. For example: http://localhost:3000/station/2

2. Given one or more bike stations, return the number of riders in the age groups [0-20, 21-30, 31-40, 41-50, 51+, unknown] who ended their trip at that station for a given day

• In Postman, go to the Body tab and select x-www-form-urlencoded and enter the following keys:
  1. A key called day with a value in the format YYYY-MM-DD. Dates are valid from 2019-04-02 to 2019-06-30.
  2. A key called stations with one or more station IDs separated by commas without spaces, for example 113,264,81. IDs for particular stations can be found in the data file.
• Send a POST request to http://localhost:3000/trip/ageGroups

3. Given one or more stations, return the last 20 trips that ended at each station for a single day
