👍 works for me.

Actually getInitialProps is the better place to do this, so it works on both client and server. Does something like this work for you?

static async getInitialProps ({query}) {
  return {
    sku: query.sku,
    quantity: query.qty,
    title: humanizeUrlParam(query.title)
  }
}

Yes, I'm using getInitialProps now. I ran into the same problem.

I preferred having everything in one file handled by one thing, but oh well. This isn't too bad, adding props to my universal "Layout HOC" that every page shares.

Example of what I settled on:

export default Layout(MyPageCmp, {
  parseQuery: Parser({
    path: s => (s || '').toLowerCase(),
    seo: true,
    title: ['seo', paramToTitle]
  })
})
