APIs REST públicas con data del Transantiago. Respuestas en JSON.

Nuevo: SCLTransit

Ignacio Hermosilla implementó un servicio web de acceso público usando los feeds GTFS de Transantiago y los puntos de acceso oficiales que normalmente requieren acuerdos con el DTPM, para que tú no tengas que hacerlo.

Está toda la información de Transantiago que puedas necesitar, con formatos de alta calidad y sin trámites. Estas APIs son las que ahora alimentan a Cromi.

APIs internas de Transantiago (no recomendadas)

Transantiago implementó estas APIs para uso interno, por lo que no hay ninguna garantía sobre su funcionalidad, mantenimiento o futura existencia. Úsalas bajo tu propio riesgo. (Probablemente no es aconsejable que las uses para nada crítico.)

A Node + TypeScript + ts-node + ESM experience that works.

The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

System Design Cheatsheet

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?
