​
1. Static Metadata Export

Most layouts and pages define metadata by exporting a metadata object. This object typically includes at least a title and description.

​
Example: app/layout.tsx

import type { Metadata } from "next";
// ...other imports

export const metadata: Metadata = {
  title: "ultimate-boilerplate-code",
  description: "ultimate-boilerplate-code",
};

​
Example: app/main/layout.tsx

export const metadata = {
  title: "Main | Boilerplate",
  description: "Main section of the Boilerplate app.",
};

​
Example: app/(content)/blogs/page.tsx

export const metadata = {
  title: "Blog | Boilerplate",
  description: "Read the latest blog posts and updates from Boilerplate.",
};

​
Example: app/(content)/privacy-policy/page.tsx

export const metadata = {
  title: "Privacy Policy | Boilerplate",
  description: "Read our privacy policy to understand how we handle your data.",
};

​
2. Dynamic Metadata with generateMetadata

For dynamic routes, metadata can be generated at runtime using the generateMetadata async function. This is useful for pages where the title, description, or OpenGraph data depend on fetched content.

​
Example: app/(content)/blogs/[id]/page.tsx

import type { Metadata } from "next";
// ...other imports

export async function generateMetadata({ params }: { params: { id: string } }): Promise<Metadata> {
  const blog = await cmsService.blogs.getById(params.id);
  if (!blog) {
    return {
      title: "Blog Not Found",
      description: "The requested blog post could not be found.",
    };
  }
  return {
    title: `${blog.title} | Your Blog Name`,
    description: blog.description,
    openGraph: {
      title: blog.title,
      description: blog.description,
      type: "article",
      publishedTime: blog.publishedDate,
      images:
        typeof blog.featuredImage === "string"
          ? [blog.featuredImage]
          : blog.featuredImage?.url
            ? [blog.featuredImage.url]
            : [],
    },
  };
}

🔄 How to Change or Update Metadata

To update the metadata for any page or layout, simply edit the metadata export or the generateMetadata function in the corresponding file.

​
To update static metadata:

  1. Open the relevant file (e.g., app/layout.tsx).
  2. Edit the metadata object:
export const metadata = {
  title: "New Page Title",
  description: "A new description for this page.",
};

​
To update dynamic metadata:

  1. Open the file with a generateMetadata function (e.g., app/(content)/blogs/[id]/page.tsx).
  2. Edit the logic or returned values as needed:
export async function generateMetadata({ params }) {
  // ...fetch or compute new metadata
  return {
    title: "Updated Title",
    description: "Updated description.",
    // ...other fields
  };
}
Note: Only fields and patterns already present in the codebase are supported. For more options, refer to the Next.js Metadata docs.
