Is evergreen-ui compatible with Frontity?

Hi! I’m trying to use evergreen-ui on a project with Frontity, but the styles are not loaded in SSR.

What I’m not sure is if Frontity is compatible with any CSS-in-JS solution or just with UI frameworks based on emotion.

Also, this library package only has the bundled version of the library, so I guess because of that it’s impossible to load those styles in SSR. Right?

Hi @orballo

We haven’t done a deep comparison of UI libraries that can be used with Frontity but I guess that any UI library what works with CSS in JS and has SSR support should work just fine

Here you have a list of some options (the ones w/ SSR support) that should work with Frontity

Hope this helps

I don’t think this is actually true. I just checked the support for SSR ( in evergreen-ui and it does offer support but it doesn’t work with Frontity. At least out of the box.

I think (I’m not sure though) that this Frontity needs an entry point for this kind of libraries. In this case evergreen-ui is exposing a function called extractStyles that I guess it should be called by Frontity somwhere.

EDIT: Ok, I made it work and the solution was quite easy (not sure if ideal though):
EDIT 2: This solution doesn’t work properly. It looks like there is some race condition that makes the styles flicker sometimes.

import React from "react";
import { connect, Global } from "frontity";
import { extractStyles } from "evergreen-ui";
import Main from "./main";

const Root: React.FC = () => {
  const { css } = extractStyles();

  return (
      <Global styles={css} />
      <Main />

export default connect(Root);

Did you try including the hydration script like in the NextJS example?

Other than that, this library seems really big, and it includes glamour (alternative CSS-in-JS to emotion) and babel-runtime (which is not needed in Frontity). It seems to have tree shaking so it would be interesting to know what actual size it has in your final bundle.

You are right. And I have run into different errors regarding references and so on. I decided to use Sancho ( instead (which seems to have started as a fork of Evergreen). And it is recommended to use with emotion. I’ll let you know how it works.
