🔌 Use External APIs. Plug into your data with remote APIs.
🕶 Powerful Metadata API. Get the best SEO for your static pages.
🔨 Build Hooks. Customize the build process to fit your needs

Quick start

Add Hydrogen CLI to your project

$ npm install hydrogen-cli --save-dev

Create a simple index.js file with below code

const page = ({ title, data, head }) => `
  <!DOCTYPE html>
  <html>
    <head>
      <title>${title}</title>
      ${head}
    </head>
    <body>
      <h2>${data.project}</h2>
      <p>${data.description}</p>
    <body>
  </html>
`;

module.exports = {
  page,
  title: 'Welcome to Hydrogen',
  data: () => ({
    project: 'Hydrogen',
    description: 'Super fast static-site generator'
  }),
  head: ({ data }) => [
    ['meta', { name: 'description', content: data.description }]
  ]
}

Run the below command to generate your template to HTML

$ npx hydrogen generate index.js

The below HTML is outputted to an HTML file with the same name as the source index.html

  <!DOCTYPE html>
  <html>
    <head>
      <title>Welcome to Hydrogen</title>
      <meta name="description" content="Super fast static-site generator" />
    </head>
    <body>
      <h2>Hydrogen</h2>
      <p>Super fast static-site generator</p>
    <body>
  </html>

Development

Pull requests are more than welcome 😃

Install Docker
Clone repo
All commands are in the package.json file

Docker is optional and if you want to debug the build process refer to 🐛 Debugging Build Process

Run the below commands:

$ yarn docker:setup # Builds Docker image and create Docker container

$ yarn docker:start # Starts Docker image

$ yarn docker:cli:dev # Runs CLI in dev mode

This will run your changes to the Hydrogen CLI over the Hydrogen documentation

Note: There are pre-commit and pre-push hooks that run tests
