inferno-mark

Create mark(up/down) components similar to styled-components.

npm install --save inferno-mark

Usage

Basic

This creates two inferno components, <Title> and <Menu>:

import Inferno from 'inferno';
import mark from 'inferno-mark';

const Title = mark.down`
# Hello World, this is my first markup component!
`;

const Menu = mark.up`
<ul>
  <li><a href="/">Home</a></li>
  <li><a href="https://github.com/dfrankland">Github</a></li>
</ul>
`;

You render them like so:

<Title />
<Menu />

Mapped components

Mark components can substitute components with user-defined ones:

import Inferno from 'inferno';
import mark from 'inferno-mark';

// Create links with both internal and external links
const Menu = mark.up`
<ul>
  <li><a href="/">Home</a></li>
  <li><a href="https://github.com/dfrankland">Github</a></li>
</ul>
`;

You can pass an object with a key of the tag name and a value of an inferno component that it should be substituted with:

// Add `target="_blank"` to external links
<Menu
  infernoMarkOptions={{
    components: {
      a: ({ children, ...props}) => (
        <a
          {...{
            ...props,
            ...(/^https?:\/\//gi.test(props.href) ? { target: '_blank' } : {}),
          }}
        >
          {children}
        </a>
      ),
    }
  }}
/>

Which will render as such:

<ul>
  <li><a href="/">Home</a></li>
  <li><a href="https://github.com/dfrankland" target="_blank">Github</a></li>
</ul>

Adapting based on props

The same powerful way that styled-components can change styles based on props, so can inferno-mark! Say for example you'd like to make a more dynamically created menu:

import Inferno from 'inferno';
import mark from 'inferno-mark';

const Menu = mark.down`
${props => props.items.map(item => `* [${item}](/${item.toLowerCase()})`).join('\n')}
`;

Pass props like so:

<Menu items={['Blog', 'Contact', 'Demo']} />

Finally, see it rendered as such:

<ul>
  <li><a href="/blog">Blog</a></li>
  <li><a href="/contact">Contact</a></li>
  <li><a href="/demo">Demo</a></li>
</ul>
