Docusaurus provides a powerful feature that displays the last updated time and last updated author for every blog post and documentation page. However, when deploying a Docusaurus website on Vercel, many developers encounter the same confusing issue:

Every page shows the exact same "last updated" date - or no date at all.

This guide explains precisely why this happens and the exact configuration you must enable on Vercel to make Docusaurus timestamps work correctly.

The primary cause for import errors on Vercel is often a mismatch between your local development environment's flexibility and Vercel's strict, serverless build process. Beyond the crucial __init__.py file, you need to pay attention to your project's overall structure, the way you write imports, and Vercel's build configuration.

Vercel doesn't have a single, built-in migration system but instead relies on standard, database-specific tools. For relational databases like Vercel Postgres, you use traditional ORMs or migration libraries. For key-value stores like Vercel KV, migration is typically a manual process of data transformation.

Deploying application servers in a serverless environment like Vercel requires a shift in how we handle database connections. Traditional relational databases expect long-lived, persistent TCP connections. In a serverless or edge runtime, functions spin up on demand and shut down immediately after returning a response.

To prevent database connection exhaustion, Vercel leverages a specialized suite of serverless and edge-compatible storage services. This guide explains how database integration works on Vercel, details first-party storage options, and provides a decision matrix to help you choose the right tool for your project.

Is SQLite Supported on Vercel?​

No, SQLite is not officially supported by Vercel for production applications because of its reliance on the local filesystem. Vercel's serverless functions are stateless and run in a read-only environment, meaning any changes to the local filesystem are discarded after the function's execution. This makes it impossible to persist the SQLite database file between function invocations. Vercel source

While you might be able to get a read-only SQLite database to work by including the database file in your deployment bundle, any attempt to write to it will fail. This limitation makes SQLite unsuitable for most dynamic web applications on the Vercel platform.

What is better Vercel or GitHub pages in terms of customization and settings​

If you're at a point where you want to build a site that goes beyond just a portfolio or a blog-something you might monetize, track analytics on, add dynamic features to, or even scale up into something bigger-it's important to choose your hosting platform wisely. GitHub Pages and Vercel are both wildly popular options, but they offer fundamentally different experiences once you want to do more than just put HTML online.

Adding a metric counter that displays the total number of blog articles and documentation pages is a great way to make a Docusaurus site feel active.

However, since Docusaurus compiles your pages statically, you cannot call internal hooks like useBlogPosts() inside static landing pages (such as src/pages/index.js). Doing so causes server-side rendering (SSR) failures during build execution on platforms like Vercel.

This guide provides a robust, build-time solution that counts flat files, subdirectories, and nested folders, saving the results to a static JSON file that can be safely imported anywhere in your project.

Many developers using Docusaurus want to display the number of blog posts they have-especially on their homepage. While this may sound trivial, doing it the right way (that works on both your local dev and production builds like Vercel) requires some thought.

Here's a simple and reliable way to implement this-no hacks, no unstable APIs, just clean engineering.
