ocsa-breadcrumb v1.0.15

OCSA Breadcrumb

A lightweight and customizable React component for rendering accessible breadcrumb navigation in your web applications.

Features

• Supports navigation hierarchy with optional links.
• Accessible with proper ARIA attributes.
• Customizable styling using external CSS.

Installation

Install the package via npm:

npm install ocsa-breadcrumb

Or with Yarn:

yarn add ocsa-breadcrumb

Usage

1. Import the Component and Styles

import React from "react";
import OcsaBreadcrumb from "ocsa-breadcrumb";

2. Provide Breadcrumb Items

The OcsaBreadcrumb component accepts an array of items representing your navigation hierarchy. Each item can include:

• label: The text to display for the breadcrumb item.
• href (optional): The URL the item links to. If omitted, the item is treated as plain text.
• isCurrent (optional): Set true for the current page (last breadcrumb item).

3. Example Markup

Here’s how you can use the component in your React project:

import React from "react";
import OcsaBreadcrumb from "ocsa-breadcrumb";

const App = () => {
  const items = [
    { label: "Home", href: "/" },
    { label: "Library", href: "/library" },
    { label: "Data", href: "/data" },
    { label: "Bootstrap", href: "/bootstrap" },
    { label: "Product", isCurrent: true },
  ];

  return (
    <div>
      <OcsaBreadcrumb items={items} />
    </div>
  );
};

export default App;

Output

The component renders a breadcrumb navigation like this:

<nav aria-label="breadcrumb" class="breadcrumb">
  <ul>
    <li><a href="/">Home</a></li>
    <li><a href="/library">Library</a></li>
    <li><a href="/data">Data</a></li>
    <li><a href="/bootstrap">Bootstrap</a></li>
    <li><span aria-current="page">Product</span></li>
  </ul>
</nav>

Customization

Optional onClick Handler

The component allows for the inclusion of an 'onClick' handler. The return value is an item in the items array.

Here’s how you can use the component in your React project:

import React from "react";
import OcsaBreadcrumb from "ocsa-breadcrumb";

const App = () => {
  const handleOnClick = (item: BreadcrumbItem) => {
    console.log(item.label)
  }

  const items = [
    { label: "Home", href: "/" },
    { label: "Library", href: "/library" },
    { label: "Data", href: "/data" },
    { label: "Bootstrap", href: "/bootstrap" },
    { label: "Product", isCurrent: true },
  ];

  return (
    <div>
      <OcsaBreadcrumb items={items}  onClickHandler={onClickHandler} />
    </div>
  );
};

export default App;

NOTE: Including the onClicker handler will render the li elements with span elements rather than anchor elements.

Default Styles

Here’s a summary of the default CSS:

:root {
  --breadcrumb-color: red;
  --breadcrumb-content: "→";
}

.breadcrumb {
  padding: 0 0.5rem;
}

.breadcrumb a {
  color: var(--breadcrumb-link-color);
  text-decoration: none;
}

.breadcrumb ul {
  display: flex;
  flex-flow: row wrap;
  list-style: none;
  margin: 0;
  padding: 0;
  align-items: end;
}

.breadcrumb li:not(:last-child)::after {
  display: inline-block;
  margin: 0 0.25rem;
  content: var(--breadcrumb-content);
  color: var(--breadcrumb-color);
}

Overriding Styles

To customize, add your own CSS rules targeting the breadcrumb class or its children:

.breadcrumb li:not(:last-child)::after {
  content: ">";
  color: blue;
}

Accessibility

• The aria-label="breadcrumb" attribute ensures the navigation is accessible.
• The aria-current="page" attribute identifies the current page for screen readers.
