Description

Server-side rendering loadable components in your gatsby application.

Installation

npm install --save gatsby-plugin-loadable-components-ssr

This plugin also requires @loadable/component as a peer dependency:

npm install --save @loadable/component

Problem

As described in the documentation a series of steps must be followed to implement server-side rendering in your app. However, it’s not trivial to apply them to a gatsby application.

Solution

This plugin implements the steps described in the link above using gatsby’s APIs, so you can use it only by adding gatsby-plugin-loadable-components-ssr in your list of gatsby plugins.

Usage

Simply add gatsby-plugin-loadable-components-ssr to the plugins array in gatsby-config.js.

// gatsby-config.js

module.exports = {
  plugins: [
    'gatsby-plugin-loadable-components-ssr',
    // OR
    {
        resolve: `gatsby-plugin-loadable-components-ssr`,
        options: {
            // Whether replaceHydrateFunction should call ReactDOM.hydrate or ReactDOM.render
            // Defaults to ReactDOM.render on develop and ReactDOM.hydrate on build
            useHydrate: true,
        },
    }
  ],
}

My gatsby-browser.js already implements replaceHydrateFunction API

This plugin uses replaceHydrateFunction API. If your application also implements this API (gatsby-browser.js) make sure you wrap your implementation with loadableReady(() => ...).

Before (from the example in here):

// gatsby-browser.js

exports.replaceHydrateFunction = () => {
  return (element, container, callback) => {
    ReactDOM.render(element, container, callback);
  };
};

After:

// gatsby-browser.js

const loadableReady = require('@loadable/component').loadableReady;

exports.replaceHydrateFunction = () => {
  return (element, container, callback) => {
    loadableReady(() => {
        ReactDOM.render(element, container, callback);
    });
  };
};
