Typography Karaoke

A simple prototype showing Karaoke-style cues using HTML5 Audio/Video and WebVTT.

Based on react-vtt and Essential React

Getting Started

$ npm install

Start the local dev server:

$ npm run server

Navigate to http://localhost:8080/ to view the app.

Commands

A core philosophy of this skeleton app is to keep the tooling to a minimum. For this reason, you can find all the commands in the scripts section of package.json.

server

$ npm run server

Input: src/main.jsx

This leverages React Hot Loader to automatically start a local dev server and refresh file changes on the fly without reloading the page.

It also automatically includes source maps, allowing you to browse code and set breakpoints on the original ES6 code:

build

$ npm run build

Input: src/main.jsx

Output: build/app.js

Build minified app for production using the production shortcut.

test

$ npm test

Input: test/main.js

Output: coverage/

Leverages ava to execute the test suite and generate code coverage reports using nyc

coveralls

$ npm run coveralls

Input: coverage/lcov.info

Sends the code coverage report generated by nyc to Coveralls.

clean

$ npm run clean

Input: build/app.js

Removes the compiled app file from build.

Converting Video Files

I suggest using ffmpeg with the following command:

$ ffmpeg -i in.mov -vcodec copy -acodec copy out.mp4
