Pass object through Link in react router

Question

Is it possible to pass an object via Link component in react-router?

Something like:
Click <

Answer 1

This isn't possible, you need to pass something that can be stored in the URL such as a string ID. You would then use that ID to perform a lookup of the object.

Answer 2

You could try JSON serializing it and then de-serializing it on the receiving end.

Answer 3

So my final conclusion on this question is that I didn't think it through properly. It seemed natural just to pass my data through the Link so I can access them in my Child component. As Colin Ramsay mentioned there is something called state in the Link but that's not the way to do it. It would work fine when the data is passed through Link only if the user clicks on something and is taken to the Child component.

The problem comes when the user accesses the url which is used in Link then there is no way to get the data.

So the solution in my case was to pass the ID in Link params and then check if my Store has the data (user accesses it via Link) and then getting this data from the Store.

Or if the data is not in the Store call the action to fetch the data from the API.

It is possible to pass an object through a Link. (it's not best practice, but it's possible)

Add your data within a query rather than params and stringify the object:

<Link to={{ 
  pathname: `/blog/${post.id}`, 
  query: {
    title: post.title, 
    content: post.content,
    comments: JSON.stringify(post.comments)
  } 
}}>Read More...</Link>

Then in your child component parse the string back in to an object:

JSON.parse(this.props.comments)

Answer 5

Using react-roter-dom ver 5.1.2 and es6

I solved the problem like this first I store it in the search part of Link to object meaning it is part of the url and supports a bookmark etc.

< Link to={{
          pathname: `${match.url}/${dogName}`,
          search: `choosenDog=${JSON.stringify({ ...dog })}` //dog is the object to pass along
        }
        } >

And then on the link we goto I get hold of it like this

const query = useQuery();
const dogString = query.get('choosenDog');
const dogObject  = JSON.parse(dogString);

Answer 6

No, you can't pass an object in params, so I would agree with you that your best plan is to pass the id to a store, have the store emit a CHANGE event, and have components query the store for info.
