react-semantic-breadcrumbs makes it easy to render semantic breadcrumbs in RDFa, microdata, JSON-LD or plain HTML5.

Installation

npm i react-semantic-breadcrumbs-v2 --save

import { BreadcrumbList, ListItem } from 'react-semantic-breadcrumbs'

import React from 'react'
import { BreadcrumbList, ListItem } from 'react-semantic-breadcrumbs'

const breadcrumbs = (
  <BreadcrumbList format="RDFa" separator=" > ">
    <ListItem url="/">Home</ListItem>
    <ListItem url="/products">Products</ListItem>
    <ListItem url="/products/iphone-7-plus">iPhone 7 Plus</ListItem>
  </BreadcrumbList>
)

Install

npm

 npm i react-semantic-breadcrumbs-v2 --save

yarn

yarn add react-semantic-breadcrumbs-v2

Basic Usage

Just import the BreadcrumbList and ListItem components and pass your desired format.

class MyComponent extends Component {
  componentDidMount() {
    // Focus the input and select "world"
    this.input.focus()
    this.input.setSelectionRange(6, 11)
  }
  render() {
    return (
      <Autocomplete
        ref={el => this.input = el}
        value="hello world"
        ...
      />
    )
  }
}

Will produce the following HTML:

 <ol vocab="http://schema.org/" typeof="BreadcrumbList">
    <li property="itemListElement" typeof="ListItem">
      <a property="item" typeof="Thing" href="/">
        <span property="name">Home</span>
      </a> >
      <meta property="position" content="1" />
    </li>
    <li property="itemListElement" typeof="ListItem">
      <a property="item" typeof="Thing" href="/products">
        <span property="name">Products</span>
      </a> >
      <meta property="position" content="2" />
    </li>
    <li property="itemListElement" typeof="ListItem">
      <a property="item" typeof="Thing" href="/products/iphone-7-plus">
        <span property="name">iPhone 7 Plus</span>
      </a>
      <meta property="position" content="3" />
    </li>
  </ol>

BreadcrumbList Props

• format string (Default: HTML5) Choose from “RDFa”, “Microdata”, “HTML5”, or “JSON-LD”. Case-insensitive.

• separator string (Default: null) The string to place between each ListItem. Ignored by JSON-LD.

• clickHandler function (Default: null) Listen for when a ListItem’s tag is clicked.

ListItem Props

• url string (Required) The page to link to.

• type string (Default: Thing) Uses schema.org types.

• clickHandler function (Default: null) Listen for when the tag is clicked. Takes precedence over BreadcrumbList’s clickHandler prop.

Import Only a Specific Format

You may only want to ever use one specific format. To cherry-pick a format for smaller browserify/rollup/webpack bundles, you can do this:

import BreadcrumbList from 'react-semantic-breadcrumbs/MicrodataBreadcrumbList'
import ListItem from 'react-semantic-breadcrumbs/MicrodataListItem'

• HTML5: HTML5BreadcrumbList & HTML5ListItem
• RDFa: RDFaBreadcrumbList & RDFaListItem
• Microdata: MicrodataBreadcrumbList & MicrodataListItem
• JSON-LD: JSONLDBreadcrumbList & JSONLDListItem
