Customizing Kotlin/JS's Webpack configuration

This is mostly notes to myself in case I ever do this again.

So, I've been doing a lot of frontend development in Typescript/React, but I'm also interested in Kotlin. I'm a full-stack engineer, so the idea of making a whole application in the same language appeals to me. (I'm aware that backend development in NodeJS exists, but I'm a fan of strict typing.)

So I've been exploring Kotlin's JS backend support.

So anyways, here's how my project is set up right now:

return bos.toByteArray()

ffmpeg time-lapse

Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

  • -r 24 - output frame rate
  • -pattern_type glob -i '*.JPG' - all JPG files in the current directory
  • -i DSC_%04d.JPG - e.g. DSC_0397.JPG
  • -s hd1080 - 1920x1080 resolution

Slower, better quality

Cordova Plugin Development Guide (iOS and Android)

Version: 0.0.1 updated 7/1/2016

Cordova Plugins are the magic that enable our mobile web app content to access the full power of Native SDKs underneath, but through clean JavaScript APIs that work the same across all platforms we target.

Building Cordova plugins is scary for many Cordova and Ionic developers, but it doesn't have to be. This simple guide walks through the what, when, why, and how of Cordova plugin development for iOS and Android.
