Eexpects window to be defined, but now always the case about react-scrollama

[jslyonnais]

Finally found a workaround.
You got right about Gatsby, but I was thinking if I can find a way to make things work.

Comment for futur people, finally I've use scrollama directly from npm, and call it on the componentDidMount of react.

componentDidMount() {
    // Loading module that require "window" to be defined
    require('intersection-observer')
    const scrollama = require('scrollama')

    const scrollThreshold = 0.33
    const scroller = scrollama()
    scroller.setup({
      // debug: true,
      step: '.scroll__step',
      threshold: scrollThreshold,
      container: '.scroll__container',
      graphic: '.scroll__graphic'
    }).onStepEnter(this.handleScrollStepEnter)
  }

Just clarifying, this is code executed by the browser, correct? Because Gatsby is a server side renderer, so if you're rendering on node, window won't be defined. Just want to make sure we're on the same page.

Great! Thanks for posting your solution.
