Dynamic Document Titles in Nextjs 15

Next.js 15 simplifies document title management and allows

tags directly in JSX. <title>

Working principle

In next.js 15, you can directly include

tags in JSX. Next.js will automatically update the document title when rendering or updating this label.

<title> The reason

This function uses the server -side rendering function of Next.js and its ability to hydrate components on the client. When the component is re -rendered due to changes in the state, Next.js will effectively update the title of the document, without additional API calls or manual DOM operations.

Dynamic title counter example

The following is an example of a counter component of the update UI and document title:

In this example:

<code class="language-javascript">'use client'

import { useState } from 'react'

export default function CounterWithDynamicTitle() {
  const [count, setCount] = useState(0)

  const incrementCount = () => {
    setCount(prevCount => prevCount + 1)
  }

  return (
    <>
      <title>Count: {count}</title>
      <div>
        <h1>Counter: {count}</h1>
        <button onClick={incrementCount}>Increment</button>
      </div>
    </>
  )
}</code>

We use HOOK to manage the state of the counter.

The label is directly included in JSX, using the current counter value.

1. When clicking the "Increment" button, it will update the counter status. useState
When the component is re -rendered, the displayed count and document titles are updated.
2. <title>
This method simplifies the management process of dynamic document title, makes it more intuitive, and reduces the needs of side effects or additional hooks.
The main advantage

Simple:

No need to separate

HOOK or external library to manage the title of the document. Response:

When the state of the component is changed, the title will be updated automatically.
