Injected not showing up

Hopefully I’m missing something simple, but the injected data isn’t showing up after build…

Here’s my config:

plugins: [
  new PrerenderSPAPlugin({
    staticDir: path.join(__dirname, 'dist'),
    routes,
    renderer: new Renderer({
      injectProperty: '__PRERENDER_INJECTED',
      inject: {
        foo: 'bar'
      },
      headless: false,
      renderAfterDocumentEvent: 'render-event',
      maxConcurrentRoutes: 5
    })
  })
]

And it builds successfully

Yet, window['__PRERENDER_INJECTED'] is undefined

Any help/thoughts would be much appreciated! Thanks!

Which browser window are you using the console in, when the Chromium puppeteer runs or when opening the generated file?

It works fine in the Chromium puppeteer, but the injected attribute will not be available in the prerendered file.

Perhaps something like this would work? (Written on a phone, no promises.)

If (window['__PRERENDER_INJECTED']) {
  const script = document.createElement('script')
  script.appendChild(document.createTextNode(`
    window['__STORED_INJECTED'] =
${JSON.stringify(window['__PRERENDER_INJECTED'])}
  `))
   document.head.appendChild(script)
}
