Important

As of react-router v6.4 there is an officially supported way of producing breadcrumbs. I recommend using this approach, but if it doesn't cover your specific use case, please let us know in the issues.

use-react-router-breadcrumbs

A small (~1.25kb gzip), flexible, hook for rendering breadcrumbs with react-router 6.

---


example.com/user/123 → Home / User / John Doe


---

Using an older version of react-router? Check out react-router-breadcrumbs-hoc which is compatible with v4 and v5.

Description

Render breadcrumbs for react-router 6 however you want!

#### Features

- Easy to get started with automatically generated breadcrumbs.
- Render, map, and wrap breadcrumbs any way you want.
- Compatible with existing route objects.

Install

yarn add use-react-router-breadcrumbs

or

npm i use-react-router-breadcrumbs --save

Usage

``js
const breadcrumbs = useBreadcrumbs();
`

Examples

Start seeing generated breadcrumbs right away with this simple example

`js
import useBreadcrumbs from "use-react-router-breadcrumbs";

const Breadcrumbs = () => {
const breadcrumbs = useBreadcrumbs();

return (

{breadcrumbs.map(({ breadcrumb }) => breadcrumb)}

);
};
`

The example above will work for some routes, but you may want other routes to be dynamic (such as a user name breadcrumb). Let's modify it to handle custom-set breadcrumbs.

`js
import useBreadcrumbs from "use-react-router-breadcrumbs";

const userNamesById = { 1: "John" };

const DynamicUserBreadcrumb = ({ match }) => (
{userNamesById[match.params.userId]}
);

const CustomPropsBreadcrumb = ({ someProp }) => {someProp};

// define custom breadcrumbs for certain routes.
// breadcrumbs can be components or strings.
const routes = [
{ path: "/users/:userId", breadcrumb: DynamicUserBreadcrumb },
{ path: "/example", breadcrumb: "Custom Example" },
{
path: "/custom-props",
breadcrumb: CustomPropsBreadcrumb,
props: { someProp: "Hi" },
},
];

// map & render your breadcrumb components however you want.
const Breadcrumbs = () => {
const breadcrumbs = useBreadcrumbs(routes);

return (
<>
{breadcrumbs.map(({ match, breadcrumb }) => (

{breadcrumb}

))}

);
};
`

For the above example...

| Pathname | Result |
| ------------- | --------------------- |
| /users | Home / Users |
| /users/1 | Home / Users / John |
| /example | Home / Custom Example |
| /custom-props | Home / Hi |

Same as the example above using Declarative Routing.

`js
import useBreadcrumbs, { createRoutesFromChildren, Route } from 'use-react-router-breadcrumbs';

const userNamesById = { '1': 'John' }

const DynamicUserBreadcrumb = ({ match }) => (
{userNamesById[match.params.userId]}
);

const CustomPropsBreadcrumb = ({ someProp }) => (
{someProp}
);

// define custom breadcrumbs for certain routes.
// breadcrumbs can be components or strings.

// map & render your breadcrumb components however you want.
const BreadcrumbTrail = ({ breadCrumbs }) => {
return (
<>
{breadcrumbs.map(({
match,
breadcrumb
}) => (

{breadcrumb}

))}

);
};

const GenerateAppRoutes = () => {
// Full declarative react router support. example: Element, children, Nested Routes
return (
} />








)
};

const AppRouter = () => {
// You could use context to set app Routes and add the breadcrumbs somewhere deeper in the application layout.
const AppRoutes = GenerateAppRoutes();
const appRouteObjects = createRoutesFromChildren(AppRoutes);
const breadCrumbs = useBreadcrumbs(appRouteObjects)
const GeneratedRoutes = useRoutes(appRouteObjects);
return (






)
}
`

For the above example...

| Pathname | Result |
| ------------- | --------------------- |
| /users | Home / Users |
| /users/1 | Home / Users / John |
| /example | Home / Custom Example |
| /custom-props | Home / Hi |

Route object compatibility

Add breadcrumbs to your existing route object. This is a great way to keep all routing config paths in a single place! If a path ever changes, you'll only have to change it in your main route config rather than maintaining a _separate_ config for use-react-router-breadcrumbs.

For example...

`js
const routes = [
{
path: "/sandwiches",
element: ,
},
];
`

becomes...

`js
const routes = [
{
path: "/sandwiches",
element: ,
breadcrumb: "I love sandwiches",
},
];
`

then you can just pass the whole routes right into the hook:

`js
const breadcrumbs = useBreadcrumbs(routes);
`

Dynamic breadcrumb components

If you pass a component as the breadcrumb prop it will be injected with react-router's match and location objects as props. These objects contain ids, hashes, queries, etc... from the route that will allow you to map back to whatever you want to display in the breadcrumb.

Let's use redux as an example with the match object:

`js
// UserBreadcrumb.jsx
const PureUserBreadcrumb = ({ firstName }) => {firstName};

// find the user in the store with the id from the route
const mapStateToProps = (state, props) => ({
firstName: state.userReducer.usersById[props.match.params.id].firstName,
});

export default connect(mapStateToProps)(PureUserBreadcrumb);

// routes = [{ path: '/users/:id', breadcrumb: UserBreadcrumb }]
// example.com/users/123 --> Home / Users / John
`

Now we can pass this custom redux breadcrumb into the hook:

`js
const breadcrumbs = useBreadcrumbs([
{
path: "/users/:id",
breadcrumb: UserBreadcrumb,
},
]);
`

You cannot use hooks that rely on RouteContext like useParams, because the breadcrumbs are not in the context, you should use match.params instead:

`tsx
import type { BreadcrumbComponentType } from "use-react-router-breadcrumbs";

const UserBreadcrumb: BreadcrumbComponentType<"id"> = ({ match }) => {
return

;
};
`

---

Similarly, the location object could be useful for displaying dynamic breadcrumbs based on the route's state:

`jsx
// dynamically update EditorBreadcrumb based on state info
const EditorBreadcrumb = ({ location: { state: { isNew } } }) => (
{isNew ? 'Add New' : 'Update'}
);

// routes = [{ path: '/editor', breadcrumb: EditorBreadcrumb }]

// upon navigation, breadcrumb will display: Update
Edit

// upon navigation, breadcrumb will display: Add New
Add
`

Options

An options object can be passed as the 2nd argument to the hook.

`js
useBreadcrumbs(routes, options);
`

| Option | Type | Description |
| ----------------- | --------------- | ---------------------------------------------------------- |
| disableDefaults | Boolean | Disables all default generated breadcrumbs. |
| excludePaths | Array | Disables default generated breadcrumbs for specific paths. |

$3

This package will attempt to create breadcrumbs for you based on the route section. For example /users will automatically create the breadcrumb "Users". There are two ways to disable default breadcrumbs for a path:

Option 1: Disable _all_ default breadcrumb generation by passing disableDefaults: true in the options object

`js
const breadcrumbs = useBreadcrumbs(routes, { disableDefaults: true });
`

Option 2: Disable _individual_ default breadcrumbs by passing breadcrumb: null in route config:

`js
const routes = [{ path: "/a/b", breadcrumb: null }];
`

Option 3: Disable _individual_ default breadcrumbs by passing an excludePaths array in the options object

`js
useBreadcrumbs(routes, {
excludePaths: ["/", "/no-breadcrumb/for-this-route"],
});
`

Order matters!

use-react-router-breadcrumbs uses the same strategy as react-router 6 to calculate the routing order.

`js
[
{
path: "users",
children: [
{ path: ":id", breadcrumb: "id-breadcrumb" },
{ path: "create", breadcrumb: "create-breadcrumb" },
],
},
];
`

If the user visits example.com/users/create they will see create-breadcrumb.

In addition, if the index route and the parent route provide breadcrumb at the same time, the index route provided will be used first:

`js
[
{
path: "users",
breadcrumb: "parent-breadcrumb",
children: [{ index: true, breadcrumb: "child-breadcrumb" }],
},
];
`

If the user visits example.com/users they will see child-breadcrumb.

API

`ts
interface BreadcrumbComponentProps {
key: string;
match: BreadcrumbMatch;
location: Location;
}

type BreadcrumbComponentType =
React.ComponentType>;

interface BreadcrumbsRoute
extends RouteObject {
children?: BreadcrumbsRoute[];
breadcrumb?: BreadcrumbComponentType | string | null;
props?: { [x: string]: unknown };
}

interface Options {
// disable all default generation of breadcrumbs
disableDefaults?: boolean;
// exclude certain paths fom generating breadcrumbs
excludePaths?: string[];
// optionally define a default formatter for generating breadcrumbs from URL segments
defaultFormatter?: (string) => string;
}

interface BreadcrumbData {
match: BreadcrumbMatch;
location: Location;
key: string;
breadcrumb: React.ReactNode;
}

// if routes are not passed, default breadcrumbs will be returned
function useBreadcrumbs(
routes?: BreadcrumbsRoute[],
options?: Options
): BreadcrumbData[];
