Archetype: Electrode React Component

Electrode flavored react component archetype.

Creating A New Component

First, install yeoman to help quickly create an empty component:

$ npm install -g yo

Now, yo can scaffold the project for you.

$ yo electrode-component

You should see something similar to the below session:

$ yo electrode-component

Welcome to the Electrode Component generator

Were going to set up a new Electrode Component, ready for development with
gulp, webpack, demo, electrode component archetype, live-reload

? What is your Package/GitHub project name? (e.g., 'wysiwyg-component') product-card
? What is the ClassName for your component? ProductCard
? What will be the npm package name? product-card
? What will be the GitHub organization username (e.g., 'walmartlabs')? electrodeio
? What is your name? (for copyright notice, etc.) arpan nanavati
? What is your GitHub Username? ananavati
? What is the name of the GitHub repo this will be published at? product-card
? Would you like to create a new directory for your project? Yes


   create .babelrc
   create .gitignore
   create .npmignore
   create .editorconfig
   create gulpfile.js
   create package.json
   create README.md
   create src/components/product-card.jsx
   create src/styles/product-card.styl
   create src/index.js
   create demo/demo.jsx
   create demo/demo.css
   create demo/examples/product-card.example
   create test/client/.eslintrc
   create test/client/components/product-card.spec.jsx

Your new Electrode Component is ready!

Your component is in '/src' and your demo files are in '/demo/*'

Type 'cd product-card' then 'gulp demo' to run the development build and demo tasks.

Configuring an existing project / manual setup

If you prefer to create your component manually or if you have an existing component that you want to migrate to using this archetype, follow the instructions below:

run the following in your project

$ npm install --save-dev electrode-gulp-helper electrode-archetype-react-component electrode-archetype-react-component-dev

Add a .babelrc to your project

The .babelrc needs to extend the archetype's babel configuration in order to apply the presents (ES2015, React) and the plugins like i18n. If your project needs additional Babel settings (like using stage 0 features) you can add them to this file. See the Babel docs for more information.

{
  "extends": "./node_modules/electrode-archetype-react-component/config/babel/.babelrc"
}

Add a gulpfile.js to your project

The gulpfile.js needs to extend the archetype's gulp tasks in order to apply the shared tasks on your new/existing electrode component. Add this following lines of code to the newly created gulpfile.js

"use strict";

const exec = require("electrode-gulp-helper").exec;

const tasks = {
  "demo": ["generate", "server-dev"],
  "demo-iso": ["dev-iso"],
  "generate": ["generate-metadata", "generate-documentation"],
  "generate-documentation": () => exec(`electrode-docgen --package ./package.json --src ./src --markdown components.md`),
  "generate-metadata": () => exec(`electrode-docgen --package ./package.json --src ./src --metadata components.json`),
  "prepublish": ["npm:prepublish"],
  "preversion": ["check-cov"]
}

require("electrode-archetype-react-component")(tasks);

Managing Dependencies

The archetypes are split into two parts: <archetype> and <archetype>-dev. Both archetypes need to be in each component and should be included in the package.json's devDependencies.

---

Project Structure

This archetype assumes an architecture as follows:

demo/
  demo.jsx
  demo.css
src
  components/
    *.jsx
  styles/
    *.css
  index.js
test
  client/
    spec/
      components/
        *.jsx?
      *.jsx?
    main.js
    test.html
.babelrc
package.json

CSS Modules + CSS next

By default, this archetype assumes you are using CSS-Modules + CSS-Next, you need to opt-in to stylus support by adding a *.styl to your project's demo/demo.styl & src/styles/*.styl

Import css files in your components and reference class names via the exported object src/components/your-component.js:

import React from "react";

import styles from "../styles/your-component.css";

class YourComponent extends React.Component {
  render() {
    return (
      <div className={styles.someStyle}>Hello Modules!</div>
    );
  }
}

Add following styling to src/styles/your-component.css

:root {
  --black: #000;
  --white: #fff;
}

.baseStyle {
  background-color: var(--black);
  color: var(--white);
}

.someStyle {
  composes: baseStyle;
  font-size: 18px;
}

Gotchas

For the demo-iso task to work, demo/demo.jsx has some limitations:

• demo/demo.jsx can't use react-router
• demo/demo.jsx can't import files that rely on webpack loaders e.g. .styl files.

This is because the server rendering uses node for both routing and import statements. Specifically for routing, react-router instances create a history that relies on DOM availability. This will break server render with an error like this: Unhandled rejection Invariant Violation: Browser history needs a DOM

Demo server config

If you would like to augment or override the demo server config you can add archetype-demo-server.config.js file to the root of the project. This file will be merged with the default config and passed into the electrode-server instance. Add any hapi plugins or settings here.

// Sample archetype-demo-server.config.js
module.exports = {
  "plugins": {
    "my-electrode-plugin": {}
  }
};

If you are enhancing / refactoring this archetype and have locally checked it out, please see CONTRIBUTING.md for our guidelines.

The main check we provide for the archetype itself is:

$ gulp archetype:check
