Compose multiple contexts; makes it easier to work with multiple Idyll runtime plugins.

Say you want to use a runtime plugin like url-state but also add your own custom context processing code:

context.js

const URLState = require('idyll-plugin-url-state');
const compose = require('idyll-context-compose');

const customContext = (ctx) => {
  // To listen for changes:
  ctx.onUpdate((newData) => {
    console.log('[custom context]', newData);
  })
}

module.exports = compose(URLState, customContext);

$ npm install --save -context-compose

To use this library, you'll need to tell Idyll to use a custom context. To do that, create a context.js file, and point Idyll to in in package.json:

"idyll": {
  "context": "./context.js"
}
