Overview

Next.js has become a popular framework for building server-rendered applications, but managing build identifiers across multiple deployment servers can often lead to complexities. The next-build-id module is designed to streamline this process by generating consistent, git-based build IDs. It ensures that your application runs smoothly in a load-balanced environment by avoiding common issues that arise when different servers may be using different build IDs.

This small but powerful package utilizes the latest git commit hash or a git tag to create unique identifiers for your builds, helping to maintain consistency in your application deployment. The module fits seamlessly into your Next.js workflow and allows for the flexibility of both asynchronous and synchronous build ID generation.

Features

• Consistent Build IDs: Generates a unique build ID based on the latest git commit hash or a tag, crucial for multi-server setups.

• Asynchronous & Synchronous Options: Supports both asynchronous and synchronous functions, catering to various use cases in your application.

• Customizable Git Options: Allows you to specify options like describe to use git tags or fallbackToSha for strict tag requirements, enhancing control over build ID generation.

• Easy Integration: Simple integration into your next.config.js file, ensuring minimal disruption to your existing setup.

• File System Storage: The generated build ID is stored in a BUILD_ID text file within your build directory, making it easy to reference during subsequent deployments.

• Prevents Common Errors: Specifically addresses issues like “invalid build file hash”, which can occur with multiple server instances, enhancing application stability.

• Flexible Directory Support: Accepts a dir option, allowing you to specify the working directory within your local git repository, ensuring compatibility in diverse project structures.
