happo-plugin-scrape

A happo.io plugin that allow you to grab Happo examples from a website.

Usage

Add the following to your .happo.js configuration file:

// .happo.js
const happoPluginScrape = require('happo-plugin-scrape');

module.exports = {
  // ...
  type: 'plain',
  plugins: [
    happoPluginScrape({
      pages: [
        {
          url: 'http://google.com',
          examples: [
            {
              name: 'Search box',
              selector: 'form[role="search"]',
            },
            {
              name: 'Logo box',
              selector: '#lga',
            },
          ],
        },
      ],
    }),
  ],
}

Configuration

pages (required)

The pages option specifies what URLs to scrape. In each page you specify a url and a list of examples. Each example has the following form:

• name A name you give the example, e.g. 'Navbar'
• selector A query selector locating the element on the page
• waitForSelector (optional) a query selector locating an element which needs to be rendered before the example is ready. This is useful if your examples have asynchronous content inside them.

In addition to url and examples, each page can also have a wrapper function. Happo will cut out the example markup from the page and render in isolation, and the wrapper function allows you to bring along any dependencies on outside wrapper elements to the screenshooting process. Here's an example injecting a #page wrapper:

{
  url: 'http://google.com',
  wrapper: (html) => `<div id="page">${html}</div>`,
  examples: [
    {
      name: 'Search box',
      selector: 'form[role="search"]',
    },
  ],
},
