Geographic

Geographic is a collection of abstractions that ease the pain of working with geographic features in JavaScript.

Installation

Node.js version 6.x.x or higher is required. To install geographic with yarn, run the command:

yarn add geographic

Alternatively, it can be installed through npm:

npm install geographic --save

Usage

Point Class

Takes point with several possible formats:

• Object
  • lat and lng properties
  • lat and long properties
  • latitude and longitude properties
• Array
  • Normally ordered, latitude, longitude
  • Inverted, longitude, latitude
• Browser Geolocation Object (with a Position constructor)
• An instance of the Point class

(Note: If instantiated with an inverted array, it should be accompanied by the inverted: true property in the options object, or the boolean true)

It includes several useful getters:

• coordinates: Outputs an object with coordinates in the { latitude: ..., longitude: ... } format.
• short: Returns an object with the format { lat: ..., long: ... }
• shortest: Returns the shortest coordinates format { lat: ..., lng: ... }
• array: An array of coordinates in the format [ [latitude], [longitude] ].
• arrayInverted: An array of coordinates in the format [ [longitude], [latitude] ].

Path Class

Takes an array of at least two points. Any valid format to instantiate a Point is valid to instantiate a Path object.

Running Tests

To run tests on geographic locally, please clone the repository, run yarn install or npm install, followed by npm run test.

To run tests on the development mode (refreshing after each file save) run the command npm run test:dev.
