nextjs 14 enviar parametros en la url How to Share State with Ease

Sharing state between routes in Next.js 14 is easier than ever, thanks to the introduction of the `useRouter` hook. This hook allows you to access the router instance and manipulate the URL.

With `useRouter`, you can easily share state between routes by passing parameters in the URL. For example, you can use the `push` method to navigate to a new page with a parameter.

To share state with ease, you can use the `query` parameter in the URL. This parameter is used to pass data between routes, making it a powerful tool for sharing state.

In Next.js 14, you can manage URL state with the useSearchParams hook, which retrieves the current search parameters from the URL. This hook returns the current search parameters as key-value pairs.

You can use the usePathname hook to retrieve the current pathname from the URL. This is useful when you need to access the part of the URL before the search parameters.

To update the URL state, you can use the replace function with the scroll: false option to prevent the page from scrolling to the top.

With the useQueryState hook from the nuqs library, you can update the URL state in a more elegant way. This hook returns a tuple with the current value of the search parameter and a function to update the search parameter.

The useQueryState hook has a similar API to the useState hook from React, making it easy to use. You can pass the key of the search parameter in the URL state and a parser for the search parameter as arguments.

To display the current search parameter in the input field, you can pass the current search parameter as a defaultValue to the input field. This ensures that the input field and the URL state are in sync.

You can define more complex data structures, such as sort keys and values, by using a dedicated parser and passing it to the createSearchParamsCache function. This allows you to reuse the same definition file for different features, like search and sort.

The useQueryStates hook is useful when you need to manage multiple URL state parameters, like search, sort, and pagination. This hook returns an object with the current values of the URL state parameters and functions to update them.

URL state is a powerful concept that allows you to store application state in the URL, making it easy to share and reuse. This is especially useful for search, sort, and pagination parameters in a web application.

In Next.js 14, you can use the nuqs library to parse search parameters from the URL state and provide a typed representation of them. This improves the developer experience by making search parameters more robust and easier to work with.

You can install the nuqs library and use its createSearchParamsCache function to parse the untyped search parameters from the URL state into a typed representation. This function takes an object with keys and parsers as input and returns an object with a parse function that can be used to transform the search parameters.

The nuqs library provides various parsers, such as parseAsNumber, parseAsBoolean, parseAsArray, and parseAsObject, which can be used to handle different types of data. You can also use the chained withDefault function to set a default value for a search parameter if it's not present in the URL state.

By using the nuqs library, you can remove the burdens of uncertain typings in your code and rely on the search parameter being a specific type. This is made possible by the library's ability to parse the search parameters from the URL state and provide a typed representation.

Next.js 14 provides client-side navigation hooks, including useSearchParams, usePathname, and useRouter, which can be used to retrieve the current URL parameters and update them based on user input. The handleSearch function, for example, uses the URLSearchParams object to manage the parameters and update the URL.

In a server component, you can accept a prop named searchParams, which is an object containing key-value pairs representing the parameters from the URL query string. This allows you to extract specific parameters, such as the selected color and size, and use them to construct a new URLSearchParams object.

By using the URL as a state manager, you can create URLs that adhere to standards and ensure compatibility across different browsers. This is particularly useful in server components, where you can use default values to handle diverse scenarios and ensure robustness in the face of potential irregularities in the data.

To apply the concept of using URLs as a state manager in Next.js 14, we can use the client-side navigation hooks like useSearchParams, usePathname, and useRouter. These hooks allow us to retrieve the current URL parameters, pathname, and routing functionalities.

The handleSearch function is a great example of how to update the URL parameters based on a search term. It utilizes a URLSearchParams object to manage the parameters, setting or deleting the 'query' parameter based on whether a term is provided.

Using replace to update the URL is a key part of this process, ensuring that the new URL is reflected in the browser's address bar. This helps keep the application state in sync with the URL.

The searchParams.get('query')?.toString() method retrieves the value of the 'query' parameter from the URL, returning the value if it exists or null otherwise. This allows us to easily access and use the search term in our application.

Sharing experiences with ease is a breeze in Next.js 14, thanks to the URL as a state manager. This approach allows users to effortlessly share curated experiences with others.

With the URL serving as the state manager, you can create links that encapsulate a specific state within the application, like the URL https://www.examplestore.com/product-page?color=pink&size=XL, which showcases products tailored to the user's preference for pink color and XL size.

Imagine a user exploring an online store's vibrant collection of XL-sized, pink-hued products, and then sharing the experience with a friend by simply copying and pasting the link.

The URL can serve as an ideal state manager, particularly in the context of server components, where default values act as a safety net, ensuring the component remains robust in the face of potential irregularities in the data it receives.

By incorporating new URLSearchParams, developers can create URLs that adhere to standards, ensuring compatibility across different browsers.

The search inputs, like /search?query=shoes&type=sneaker, demonstrate how the URL can be used to share specific search queries with others.

In a Next.js server component, you can get route parameters from params.

To access sub-pages, you can nest more folders based on the [uid] parameter. For example, you can create a folder structure like /app/[locale]/profile/[userId]/page.tsx. This will allow you to access sub-pages like localhost:3000/us/profile/0101021324.

You can get the params in your page, server-side, using const {locale, userId} = params.
