gatsby-plugin-fela

Provide drop-in support for using the css-in-js library fela.js including server rendering.

Install

npm install --save gatsby-plugin-fela

How to use

Add the plugin to your gatsby-config.js.

plugins: [`gatsby-plugin-fela`];

to configure the fela renderer add a fela.config.js file to the root of your gatsby project:

module.exports = {
  plugins: [ /* add your plugins here */ ],
  enhancers: [ /* add your enhancers here */ ]
  // ...
}

Unfortunately I didn’t find a way to use this file for SSR and browser, because I wasn’t able to load this file from the browser without having access to node and webpack imports are very limited. So at the time this plugin only adds fela for server side rendering. You have to add it in the browser yourself. So create a gatsby-browser.js file in the root of your gatsby project and add this code:

import React from 'react'
import { RendererProvider } from 'react-fela'
import { createRenderer } from 'fela'

exports.wrapRootElement = ({ element }) => {
  let config;
  try {
    config = require(`./fela.config.js`);
  } catch (e) {
    console.log(e);
  }
  const renderer = createRenderer(config);

  return (
    <RendererProvider renderer={renderer}>
      {element}
    </RendererProvider>
  );
};

Importing fela plugins

When you’re importing fela plugins, don’t forget your fela.config.js file is a commonjs file, but plugins are transpiled using babel from ES6 import/export syntax into format that uses interopRequireDefault function. So for correct import of the plugin, you have to import .default from the package as shown at the example below.

const unit = require("fela-plugin-unit").default

module.exports = {
  plugins: [
    unit(),
  ],
}
