It’s probably worth pausing here a second to observe an opinion that’s lurking in this implementation: it is actually valid to have multiple values for the same search parameter. The setSearchParamsState method definition looks somewhat complicated, but essentially all it does is get the contents of the existing search parameters and apply the new state for the current property. It interrogates the searchParams for the supplied searchParamName, and if it isn’t present, falls back to the defaultValue. The Hook then goes on to wrap the useSearchParams Hook. defaultValue: the fallback value if there’s no value in the query string.searchParamName: the name of the query string parameter where state is persisted.When initialized, the Hook takes two parameters: The above Hook can roughly be thought of as useState, but storing state in the URL. It achieves this with the useSearchParams Hook: import ), If you’re working with React, React Router makes consuming state in the URL, particularly in the form of a query string or search parameters, straightforward. The above URL goes further and stores multiple pieces of state: the greeting and name. The above URL is storing a single piece of state: the greeting.

This is a primitive upon which we can build as long as the URL limit (around 2,000 characters) is not exceeded, we’re free to persist state in a URL. Thanks to the URLSearchParams API, it’s possible to manipulate the query string without round-tripping to the server. The search parameters are particularly powerful as they are entirely generic and customizable. A URL can contain the required state in the form of the route and the query string/search parameters. So if you want others to see what you can see in an application, you’re reliant on them carrying out the same actions that got your application into its current state.ĭoing that can be time-consuming and error-prone, so wouldn’t it be great if there was a simple way to share state? A stateful URLĪn effective way to share state between users, without needing a backend for persistence, is with the URL. However, there is a disadvantage to using useState that state is not persistent and not shareable.

SetTotal('hello John') // will set greeting to 'hello John' Usage of the useState Hook looks like this: const = useState('hello world')

Performance: useSearchParamsState Hook vs.This post demonstrates a simple React Hook that stores state in the URL query string, building on top of the React Router useSearchParams Hook. The React useState Hook is a great way to persist state inside the context of a component in React.

Here is my code fo the Search Input field. However, navigating from /teams/111111 to teams/222222 changes the url but the component is still /teams/111111. It is not updating the view if the url changes parameters.įor example, navigating from /users/454545 to /teams/555555 works as expected. I just implemented a global search in my website and I started having issues with React-Router.
