feat: use EventTarget #205

Open Symbitic opened 4 weeks ago

Symbitic commented 4 weeks ago

I extracted the first part of my bigger PR: this just replaces all usage of EventDispatcher with EventTarget.

I tried a few experiments with how to document events. I recommend running npm run docs and seeing the documentation for the Bluetooth class.

thegecko commented 3 weeks ago

Thanks, can you fix up the linting? I'm also keen to keep the noble adapter around for now.

Symbitic commented 3 weeks ago

I ran eslint with --fix and re-added the noble-adapter file.

For documentation, I experimented with two styles: an "Events" category in the description of every class, and a Markdown table in the override of addEventListener.

Do you have a preference?

Thanks for the update!

I think tying the events to the class directly makes it more readable and discoverable. It's not a strong preference though!

I added an "Events" category to every class. Should be ready for merging.

@Symbitic I tried this locally and see many of the tests are failing. The expected output looks like:

> yarn test          
yarn run v1.22.22
$ mocha --timeout 10000 test/*.test.js

  bluetooth module
    ✔ should describe basic constants

  device
    ✔ should return a device with requestDevice
    ✔ should have device properties
    ✔ should have gatt properties
    ✔ should connect and disconnect (2355ms)
    ✔ should have disconnect event (2270ms)

  devices
    ✔ should return no devices with getDevices (2058ms)
    ✔ should return one device with getDevices after a request (2215ms)
    ✔ should forget devices (4225ms)

  all devices
    ✔ should return all devices with getDevices (2045ms)

    ✔ should get characteristics
    ✔ should get characteristic
    ✔ should read characteristic value (64ms)
    ✔ should write characteristic value (63ms)

    ✔ should emit characteristic value changed event (1974ms)

  descriptors
    ✔ should get descriptors
    ✔ should get descriptor

  bluetoothuuid
    ✔ should get service
    ✔ should get characteristic
    ✔ should get descriptor
    ✔ should get canonical uuid

  23 passing (41s)

But this is the output from this PR:
