Changelog Template is a minimal template built with Next.js for showcasing product/project updates.

It allows you to present releases, new features, and bug fixes to users in a clean, chronological timeline.

You can use this template to create a dedicated page that communicates changes for a software product, an open-source project, or an internal tool.

How to Use It

1. Clone or download the project repository from GitHub.

2. Install the necessary dependencies by running the following command in your project’s root directory.

pnpm install

3. Start the local development server. You can now view the application by opening http://localhost:3000 in your web browser.

pnpm dev

4. To add a new changelog entry, create a new MDX file inside the changelog/content/ directory. The filename must follow the YYYY-MM-DD.mdx format. Each file requires frontmatter at the top to define its metadata.

FAQs

Q: Can I customize the timeline design and colors?
A: Yes, you can modify the visual design by updating the Tailwind CSS configuration and CSS custom properties.

Q: Can I integrate this with automated release processes?
A: Yes, you can create changelog entries programmatically by generating MDX files as part of your CI/CD pipeline.

Q: Does the template support multiple languages or localization?
