To work off the answer above  https   stackoverflow com a 44860918 2011818   you can also send the objects inline the  To  inside the Link object         lt Route path   foo  fooId  component  foo     gt    lt Link to   pathname  foo newb  sampleParam   Hello   sampleParam2   World      gt  CLICK HERE  lt  Link gt   this props match params fooId   newb this props location sampleParam    Hello  this props location sampleParam2    World

there is a way you can pass more than one parameter  You can pass  to  as object instead of string      your route setup  lt Route path   category  catId  component  Category     gt      your link creation const newTo        pathname    category 595212758daa6810cbba4104      param1   Par1         link to the  location     see  https   reacttraining com react-router web api location   lt Link to  newTo  gt   lt  Link gt      In your Category Component  you can access the data like this this props match params catId    this is 595212758daa6810cbba4104  this props location param1    this is Par1

I had the same problem to show an user detail from my application   You can do this    lt Link to    ideas   this props testvalue   gt Create Idea lt  Link gt    or    lt Link to  ideas hello  gt Create Idea lt  Link gt    and    lt Route name  ideas  value  handler  CreateIdeaView    gt    to get this via this props match params value at your CreateIdeaView class   You can see this video that helped me a lot  https   www youtube com watch v ZBxMljq9GSE

If you are just looking to replace the slugs in your routes  you can use generatePath that was introduced in react-router 4 3  2018   As of today  it isn t included in the react-router-dom  web  documentation  but is in react-router  core   Issue 7679    myRoutes js export const ROUTES       userDetails   quot  user  id quot          MyRouter jsx import ROUTES from    routes    lt Route path  ROUTES userDetails        gt       MyComponent jsx import   generatePath   from  react-router-dom  import ROUTES from    routes    lt Link to  generatePath ROUTES userDetails    id  1     gt ClickyClick lt  Link gt   It s the same concept that django urls reverse has had for a while

The simplest approach would be to make use of the to object within link as mentioned in documentation  https   reactrouter com web api Link to-object  lt Link   to        pathname   quot  courses quot       search   quot  sort name quot       hash   quot  the-hash quot       state    fromDashboard  true  id  1          gt    We can retrieve above params  state  as below  this props location state      fromDashboard  true  id  1

Typescript  For approach mentioned like this in many answers    lt Link     to            pathname    my-path           myProps                hello   Hello World                   gt      Press Me  lt  Link gt    I was getting error      Object literal may only specify known properties  and  myProps  does not exist in type  LocationDescriptorObject     location  Location     LocationDescriptor     Then I checked in the official documentation they have provided state for the same purpose   So it worked like this    lt Link     to            pathname    my-path           state                hello   Hello World                   gt      Press Me  lt  Link gt    And in your next component you can get this value as following   componentDidMount         console log  received   this props location state hello

See this post for reference  The simple is that    lt Link to         pathname   your location        state   send anything from here       Now you want to access it   this props location state

This line is missing path    lt Route name  ideas  handler  CreateIdeaView    gt    Should be    lt Route name  ideas  path    testvalue  handler  CreateIdeaView    gt    Given the following Link
