Developer Instructions

After downloading the source code, add the platform specific versions of youtube-dl and ffmpeg for the current platform as shown:

resources
├ ffmpeg
│ └ ffmpeg.exe
└ youtube-dl
  └ youtube-dl.exe

Install dependencies (electron and electron-builder) and run the app (on port 5500):

npm install
npm run dev

Build Instructions

Before proceeding with the build steps, create a folder named releases in the root directory. The build process performs the following steps:

Clean output directories (removes dist and removes files from releases)
Build distributable(s) for target platform(s)
Compress portable distributions (requires tar and 7z)
Rename distributables in the format downline-{version}-{type}-{platform}.{ext}
Move all distributables to releases folder

Place the dependencies for the target platform (e.g. for windows) in a folder as shown:

resources
│ ...
└ win
  ├ ffmpeg
  │ └ ffmpeg.exe
  └ youtube-dl
    └ youtube-dl.exe

Build for the target platform (win, mac or linux):

npm run build:platform

Build for all three platforms in parallel:

npm run build:all

If you would like to build for a platform without all the extra build steps (or npm run build:platform fails), run:

./node_modules/.bin/electron-builder build --platform
