nextjs tailwind

Nextjs as a static site generator

The starting sample project was cloned from

tw-sb-rtl-starter

The final project can be found here:

source code

live site

Install nextjs

yarn add next emotion@10.0.27 emotion-server@10.0.27 @emotion/core@10.1.1 @component-controls/nextjs-plugin -D

component-controls has two configuration files - one is used during build-time in a nodejs environment, the other is used during run-time in a browser environment.

The rough equivalents of Storybook for those two configuration files are main.js and preview.(js|ts)

Update configuration

You can keep the main.js Storybook configuration file and rename preview.ts to runtime.tsx:

.storybook/main.js

module.exports = {
  stories: ['../src/**/*.stories.@(js|jsx|ts|tsx|mdx)'],
  // remove all storybook addons
};

.storybook/runtime.tsx

// empty file

Configuration file path

By default, the Storybook configuration file is kept in a folder name .storybook, while component-controls uses a .config folder. We will configure the nextjs plugin in next.config.js.

next.config.js

const withStories = require('@component-controls/nextjs-plugin/build');
module.exports = withStories({
  future: {
    webpack5: true, //use webpack 5 for nextjs
  },
  configPath: '.storybook',
});

Create page templates

The component-controls nextjs plugin needs to be set up with page templates in a pages folder of your project

mkdir pages

You can either copy the pages from this github repo or follow the getting started with nextjs tutorial.

Inject tailwind css

pages/_app.js

import React from 'react';
import NextApp from 'next/app';
import '../src/tailwind.output.css';
export default class App extends NextApp {
  render() {
    const { Component, pageProps } = this.props;
    return <Component {...pageProps} />;
  }
}

Launch scripts

Next, you should add the gatsby develop and gatsby build scripts to the project's package.json

package.json

"scripts": {
    ...
    "tailwind:watch": "postcss ./src/styles/tailwind.css -o ./src/tailwind.output.css --watch",
    "docs:build": "next build && next export",
    "docs:start": "next -p 6006",
    "lint": "eslint \"./src/**/*.{ts,tsx,js,jsx}\"",
    ...
  },

At his point, you can start your documentation site

yarn docs:start

And a new documentation site should be up and running

gatsby site

Configure documentation site

You can configure the name, site and various other site parameters for the new documentation site

.storybook/main.js

module.exports = {
  stories: ['../src/**/*.stories.@(js|jsx|ts|tsx|mdx)'],
  siteUrl: 'https://tailwind-gatsby-controls-starter.netlify.app',
};

.storybook/runtime.tsx

import { RunOnlyConfiguration } from '@component-controls/core';
const config: RunOnlyConfiguration = {
  analytics: 'UA-XXXXXXXXX-X',
  title: `Tailwind component-controls`,
  description: `Tailwind project with typescript, react testing library and component-controls`,
  author: `@component-controls`,
};
export default config;

Add testing page

component-controls allows adding fully customizable documentation pages to your site and comes with package of pre-configured pages.

.storybook/main.js

const { defaultBuildConfig } = require('@component-controls/core');
module.exports = {
  stories: ['../src/**/*.stories.@(js|jsx|ts|tsx|mdx)'],
  siteUrl: 'https://tailwind-gatsby-controls-starter.netlify.app',
  pages: {
    story: {
      tabs: {
        ...defaultBuildConfig.pages.story.tabs,
        test: '@component-controls/pages/TestingPage',
      },
    },
  },
};

The new Testing Page should now be visible

testing page

Add jest snapshot tests

The @component-controls/cc-cli package is automatically creating jest snapshot tests from your existing stories. It has an easy to use command-line interface that we will use in this example but also offers a fully customizable API.

Install the cc-cli package

yarn add @component-controls/cc-cli -D

Configure test:create script

We will launch the cc-cli command-line tool to create automatically tests for all our existing stories.

package.json

{
  "name": "tailwind-storybook-controls",
  ...
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test:create": "cc-cli -c ./.config -o tests -t stories.test.ts -n components -f ts",
    "test": "yarn jest"
    "eject": "react-scripts eject",
    ...
  },
  ...
}

Run the tests

yarn test

Running the test:create script test will a tests file stories.test.ts (typecript format) in the tests folder.

After running the tests, you should have a file tests/__snapshots__/stories.test.js.snap, with snapshots like this one:

tests/snapshots/stories.test.js.snap

exports[`Components/Button Primary 1`] = `
<DocumentFragment>
  <button
    class="rounded-md focus:outline-none focus:shadow-outline bg-primary-500 text-white hover:bg-primary-600 py-4 px-8"
    type="button"
  >
    Button Label
  </button>
</DocumentFragment>
`;
