Transpile TypeScript to Espruino flavor of JavaScript for ESP8266/ESP32 microcontrollers template project. Writing safe, maintainable, and testable code is the projects goal.

npm install

Adjust port used in package.json then:

npm run-script transpile

Permanently save transpile code on device.

npm run-script commit

Monitor serial responses

npm run-script monitor

npm test

Code coverage in coverage/index.html

The simplest example in blinky.ts. Blink a LED.

const BUILTIN_LED = 2;
export function blinkly(intervalMs: number = 2000, pin: number = BUILTIN_LED) {
  let toggleStatus = false;
  setInterval(function () {
    toggleStatus = !toggleStatus;
    digitalWrite(pin, toggleStatus);
  }, intervalMs);
}

More advance example using a class, properties, testing using mocks and type checking: AdvanceBlinky class in advanceBlinky.ts with test at test/blinky.spec.ts.
