OASA Telematics API

npm npm GitHub Workflow Status

The (unofficial) Telematics API of Athens' public buses, complete with types and helper methods 🚌🚌🚌

This is the package that powers the popular greek messenger bot "Ξ ΟŒΟ„Ξ΅ έρχΡται το λΡωφορΡίο ΞΌΞΏΟ… 🚌".

Getting Started

Install the package: $ npm i oasa-telematics-api

import { APIRequests, APIHelpers } from 'oasa-telematics-api';

const api = new APIRequests();
const b = new APIHelpers();

(async () => {
    // You can fetch all the lines:
    console.log("You can fetch all the lines...");
    console.log(await api.webGetLines());

    // You can fetch a single line:
    console.log("You can fetch a single line...");
    console.log(await b.findLine('140'));

    // You can fetch a stop of a line:
    console.log("You can fetch a stop of a line...");
    const line = await b.findLine('140');
    if (line) {
        const { directions } = await b.getDirectionsOfLine(line.LineCode)
        const [come, go ] = directions;
        console.log(await b.findStop('LAMIAS', come.RouteCodes));

        // Or in greek
        console.log("Or by searching in Greek...");
        console.log(await b.findStop('Ξ›Ξ‘ΞœΞ™Ξ‘Ξ£', come.RouteCodes));

        // Or by searching with a typo
        console.log("Or by searching with a typo...");
        console.log(await b.findStop('Ξ›Ξ‘ΞœΞ™Ξ‘', come.RouteCodes));

        // And then you can check which buses are passing through that stop:
        console.log("And then you can check which buses are passing through that stop...");
        const stops = await b.findStop('Ξ›Ξ‘ΞœΞ™Ξ‘', come.RouteCodes);
        if (stops.length > 0) {
            console.log(await api.getStopArrivals(stops[0].StopCode));
        }
    }
})();

Also, feel free to open an issue if you want to ask or suggest anything :)

Can I use my own request method?

Yes. The constructors APIRequests and APIHelpers can get a request function as an argument.

The request function will need to have the form:

export type RequestFunction = <T>(url: string, query: string, ...params: any[]) => Promise<T>;

You can see a reference request function here.

Why would I want to use my own request method?

Caching.

Also, see below...

Can I use this for frontend development?

Yes. But you'll need to create a custom request function using the browser fetch method instead of the default one installed (node-fetch). You can see the above question for more details.

Next Steps

  • Add tests
  • Add some more helper methods for schedule management
