It is a hook that returns breadcrumbs to create breadcrumbs for the current page. The breadcrumbs is an array of objects with the following properties:

label: the label of the resource.
href: the route of the resource's list action.
icon: the icon of the resource.

Usage

import React from "react";
import { useBreadcrumb } from "@refinedev/core";

export const Breadcrumb: React.FC = () => {
  const { breadcrumbs } = useBreadcrumb();

  return (
    <ul>
      {breadcrumbs.map(({ label, href, icon }) => (
        <li key={label}>
          {icon}
          {href ? <a href={href}>{label}</a> : label}
        </li>
      ))}
    </ul>
  );
};

Examples

Resource

The breadcrumbs are created with your resource definitions. For example, if you have a resource with the following definition:

[
  {
    name: "posts",
    icon: <PostsIcon />,
    list: "/posts",
    create: "/posts/create",
  },
];

On the list page of the posts resource, the breadcrumbs look like this:

[
  {
    label: "Posts",
    href: "/posts",
    icon: <PostsIcon />,
  },
];

On the create page of the posts resource, the breadcrumbs look like this:

[
  {
    label: "Posts",
    href: "/posts",
    icon: <PostsIcon />,
  },
  { label: "Create" },
];

If the resource has no icon property, the icon property of the breadcrumbs is undefined. Likewise, if the resource's list page is not found, the href property of the breadcrumbs is undefined.

Nested resource

If you have a nested resource definition as below:

[
  {
    name: "cms",
  },
  {
    name: "users",
    list: "/users",
    create: "/users/create",
    meta: { parent: "cms" },
  },
];

On the list page of the users resource, the breadcrumbs look like this:

[
  { label: "Cms" },
  {
    label: "Users",
    href: "/users",
  },
];

On the create page of the users resource, the breadcrumbs look like this:

[
  { label: "Cms" },
  {
    label: "Users",
    href: "/users",
  },
  { label: "Create" },
];

Adding a Home/Root Page

In earlier versions of Refine, <Refine> component accepted DashboardPage which could be used to add an index page to your app. With the changes in routerProvider API of Refine, DashboardPage is deprecated. You can now define an index route manually in your router package.

In earlier versions, the home icon in the Breadcrumb was created by the DashboardPage, but now it is rendered if you define an action route as / in any one of your resources. It will be rendered with the home icon regardless of the current route. You can also hide the home icon by setting showHome to false.

[
  {
    name: "dashboard", // name of the resource is not important for the `useBreadcrumb` hook
    list: "/", // If any one of your resources has a list action with `/` route, the home icon will be rendered
  },
];

i18n support

If the resource definition has a label property, useBreadcrumbs uses the label property. Otherwise, the name property of the resource is used. Likewise, if the resource definition has route property, useBreadcrumbs uses the route property. Otherwise, the name property of the resource is used.

If a label is not provided in your posts resource, useBreadcrumb uses the useTranslate hook to translate the names.

For CRUD operations (list,create,edit,show) the useBreadcrumb uses the actions key to translate the key translate(`actions.${action}`).

For example, create action should look like: translate(`actions.create`)
