How to use it

The component is written with customization and ease-of-use in mind. It therefore comes with some useful default which you can override if needed.

The most basic setup

Using just the default provided by the component.
<Breadcrumbs routes={routes} />

The default behaviour

The component takes five props in addition to routes.
| PropName | PropType | Default | Description | | --------------------- | ----------------------------------------------------- | ------------- | ----------------------------------------------------- | | className | PropTypes.string | breadcrumbs | The className for the div wrapping your breadcrumbs | | params | PropTypes.object | {} | Typically the params from react-router | | resolver | PropTypes.func | See below | A text resolver for customized texts | | createLink | PropTypes.func | See below | Hook for overriding how links are created | | createSeparator | PT.oneOfType([PT.func, PT.string]) | See below | Hook for override how separators are created | | wrappingComponent | PT.string | div | Determines the tagName for the wrapping component | | prefixElements | PT.oneOfType([PT.arrayOf(PT.element), PT.element]) | none | Elements to be added infront of the breadcrumb | | suffixElements | PT.oneOfType([PT.arrayOf(PT.element), PT.element]) | none | Elements to be added at the end of the breadcrumb |
// Default for `resolver` prop
const defaultResolver = (key, text, routePath, route) => key;

// Inputs and how they are determined:
// key:         route.breadcrumbName || ||
// text:        paramsReplaced(key) (based on the `params` props)
// routePath:   All current routes, except the last one
// route:       Your current <Route /> (last in <Route>-chain

// Default for `createLink` prop
const defaultLink = (link, key, text, index, routes) => <Link to={link} key={key}>{text}</Link>;

// Inputs and how they are determined:
// link:        The suggested href for this crumbs
// key:         The suggested react-key <Component key={key} />
// text:        The resulting text, either from the defaultResolver or your custom resolver
// routes:      All current routes, including the last one

NB! Its also possible to just send a string as this props-value.
// Default for `createSeparator` prop
const defaultSeparator = (crumbElement, index, array) => <span key={`separator-${index}`}> > </span>;

// Inputs and how they are determined:
// crumb:       The react-element (crumb) you are creating a separator after.
// index:       The index of the current crumb
// array:       All crumbs that a being generated


A lot-of customization can be done through the props of the component, but in many cases it will be enough to add props to your Routes. The component looks for three specific props on the Route object.
  1. breadcrumbIgnore, will remove the Route for any breadcrumb-path
  2. breadcrumbName, will override the and sent to the resolver
  3. breadcrumbLink, will override the Route.path and be subject to params replacement.

Which can be used to name your breadcrumbs exactly as you want.

BreadcrumbIgnore Example

NB. Theres is currently a bug where paths become wrong if this is used on a 'Route' with a path other then '/'
// The example allways show 'Example' as its first breadcrumb.
// To remove this, add 'breadcrumbIgnore' as a prop
<Route path="/" name="Examples" component={App} breadcrumbIgnore > 

BreadcrumbName Example

// To over the name-prop, we've added the breadcrumbName-prop. 
<Route name="UserDetails" path="details" component={UserDetails} breadcrumbName="Details" />

// The resulting name will be sent to the resolver as the 'key' and i param-replaced form as 'text' (see resolver)
<Route name="UserLocator" path=":userId" component={User} breadcrumbName=":userId">

BreadcrumbLink Example

// Overriding the path-prop
// NB. Can break functionality if abused
<Route path="/" name="Examples" component={App} breadcrumbLink="/my-application" >

Peer dependencies

This component has the newest react and react-router as peerdependenies, but will most likely work with lower version. If you test the component with lower versions of react and/or react-router please let me know so that the dependencies can be adjusted.
"react": "^0.14.9 || ^15.3.0",
"react-dom": "^0.14.9 || ^15.3.0",
"react-router": "^2.0.1 || ^3.0.0"

In addition a polyfill for Array.includes is needed if you are targeting a browser which does not support this.

Undocumented / TODO

  1. If a breadcrumbLink and the route.path is both falsy the component uses a empty string. Suggest adding a default message/invariant/console.error to warn the user
