Reactronica
React audio components for making music in the browser.
React treats UI as a function of state. This library aims to treat music as a function of state, rendering sound instead of UI. Visual components live side by side with Reactronica, sharing the same state and elegantly kept in sync.
Uses ToneJS under the hood. Inspired by React Music.
Warning: Highly experimental. APIs will change.
Install
$ npm install --save reactronica tone
Note: Use React version >= 16.8 as Hooks are used internally.
Template
To get started quickly with Create React App and Reactronica, just run the command below:
$ npx create-react-app my-app --template reactronica

Known Issues
- Tried to migrate library to Typescript, however having issues with
rollup-plugin-typescript
being too strict while bundling. (branchjest-typescript
- 26/12/19). - Tone installed as dependency due to
Module not found: Can't resolve 'tone' in '/Users/kcheung/Development/unkleho/reactronica/dist'
issue inwebsite/
. Keep as both dependency and peer for now. - Latest Tone (13.4.9) has this issue
Cannot assign to read only property 'listener' of object '#<AudioContext>'
due tohttps://stackoverflow.com/questions/55039122/why-does-tone-js-not-play-nice-in-a-svelte-component
. Tone cannot be bundled with Reactronica and has to be a peer dependency for now. - If you get
Hooks can only be called inside the body of a function component.
, have a look at https://github.com/facebook/react/issues/14721. Try going into the examples folder and runningnpm link ../node_modules/react
.
