Multiple params with React Router

I use React 15.0.2 and React Router 2.4.0. I want to pass multiple params to my route and I'm not sure how to do it in the best way:

<Route name="User" path="/user" component={UserPage}>   
    <Route name="addTaskModal" path="/user/manage:id" component={ManageTaskPage} />
</Route>

And what is want is something like:

 <Route name="User" path="/user" component={UserPage}>  
    <Route name="addTaskModal" path="/user/manage:id:type" component={ManageTaskPage} />
</Route>

As @alexander-t mentioned:

path="/user/manage/:id/:type"

If you want to keep them optional:

path="/user/manage(/:id)(/:type)"

React Router v4

React Router v4 is different than v1-v3, and optional path parameters aren't explicitly defined in the documentation.

Instead, you are instructed to define a path parameter that path-to-regexp understands. This allows for much greater flexibility in defining your paths, such as repeating patterns, wildcards, etc. So to define a parameter as optional you add a trailing question-mark (?).

So, to define optional parameters, you can do:

path="/user/manage/:pathParam1?/:pathParam2?"

i.e.

<Route path="/user/manage/:pathParam1?/:pathParam2?" component={MyPage} />

Whereas, The mandatory Parameters are still same in V4:

path="/user/manage/:id/:type"

To access PathParam's value, you can do :

this.props.match.params.pathParam1

Try this

<Route name="User" path="/user" component={UserPage}>  
  <Route name="addTaskModal" path="/user/manage/:id/:type" component={ManageTaskPage} />
</Route>

<Route path="/:category/:id" exact component={ItemDetails} />

In the component, using useParams from react-router-dom,

import { useParams } from 'react-router-dom'
export default function ItemDetails(props) {

const {id, category} = useParams();
return (
    <div className="">
        {id}
        {category}
    </div>
)

Here is the solution, without props and using routing library.

For the optional param fields, for some reason it works fine without the slash before the colon inside the braces (). React-router 2.6x
