Style attribute binding gets overridden by pre-rendering

[ricricucit]

I build a simple "parallax" using vuejs style binding :style and I found out that the prerender-spa-plugin executed phantomjs, which added static inline styles (eg. style="-webkit-transform: translateY(0px);") which, once generated, overrides the actual style-binding of the app.

For this reason I would maybe propose the possibility of skipping inline-style attributes when pre-rendering the application...would that be easy to implement, or: does someone could point me towards a (good) solution to work around this issue?

Great idea!

I'm currently working on an adaptor of this that employs Chrome Headless via puppeteer instead of phantomJS, so we'll soon have more robust API's as that matures.

In terms of what you can do right now to solve this issue, consider using options.postProcessHtml by providing regex to strip out applicable:

<div class="foo" style="transform: translate3d(0, 0, 1);"> ... </div>
<!-- ➡️  -->
<div class="foo">... </div>

webpack.config.js

// Manually transform the HTML for each page after prerendering,
// for example to set the page title and metadata in edge cases
// where you cannot handle this via your routing solution.
//
// The function's context argument contains two properties:
//
// - html :: the resulting HTML after prerendering)
// - route :: the route currently being processed
//            e.g. "/", "/about", or "/contact")
//
// Whatever is returned will be printed to the prerendered file.
postProcessHtml: function (context) {
  var titles = {
    '/': 'Home',
    '/about': 'Our Story',
    '/contact': 'Contact Us'
  }
  return context.html.replace(
    /<title>[^<]*<\/title>/i,
    '<title>' + titles[context.route] + '</title>'
  )
}

Hope that helps. Cheers.

sounds good, thanks for the tip!

@drewlustro I'm not 100% sure yet, but this seems to be a problem for router link as well. Seems to be rendered as regular URL and not getting picked up by the vue-router...

[drewlustro]

What is problematic? This plugin is supposed to render static, vanilla HTML.

router link is a custom element defined by vue-router. Thus, it would not (and should not) prerender as anything but an ordinary <a> link.

no, sorry, I'm not sure I should be the one closing issues 😛
