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?

Minimum Viable Async with Node 6

With the release of Node 6.0.0, the surface of code that needs transpilation to use ES6 features has been reduced very dramatically.

This is what my current workflow looks like to set up a minimalistic and fast microservice using micro and async + await.

The promise

APIs REST p煤blicas con data del Transantiago. Respuestas en JSON.

Nuevo: SCLTransit

Ignacio Hermosilla implement贸 un servicio web de acceso p煤blico usando los feeds GTFS de Transantiago y los puntos de acceso oficiales que normalmente requieren acuerdos con el DTPM, para que t煤 no tengas que hacerlo.

Est谩 toda la informaci贸n de Transantiago que puedas necesitar, con formatos de alta calidad y sin tr谩mites. Estas APIs son las que ahora alimentan a Cromi.

APIs internas de Transantiago (no recomendadas)

Transantiago implement贸 estas APIs para uso interno, por lo que no hay ninguna garant铆a sobre su funcionalidad, mantenimiento o futura existencia. 脷salas bajo tu propio riesgo. (Probablemente no es aconsejable que las uses para nada cr铆tico.)

REPL with standalone await + babel transform
const repl = require('repl');
const babel = require('babel-core');
function preprocess(input) {
const awaitMatcher = /^(?:\s*(?:(?:let|var|const)\s)?\s*([^=]+)=\s*|^\s*)(await\s[\s\S]*)/;
const asyncWrapper = (code, binder) => {
let assign = binder ? `global.${binder} = ` : '';
return `(function(){ async function _wrap() { return ${assign}${code} } return _wrap();})()`;
};

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!
