@ynode/versionify

Copyright (c) 2025 Michael Welter me@mikinho.com

A simple and lightweight Fastify plugin to expose your application's name and version from package.json.

It automatically handles content negotiation to respond with JSON, HTML, or plain text based on the client's Accept header.

Installation

Install the package and its required peer dependency, fastify.

npm install @ynode/versionify fastify

Options

You can pass an options object as the second argument to register.

Option	Type	Default	Description
prefix	string	undefined	Optional Fastify route prefix.
path	string	"/version"	The URL path to expose the version endpoint.
pkg	object	undefined	A package.json object. If not provided, the plugin will automatically load package.json from your project root.

Basic Usage

import versionify from "@ynode/versionify";

// Register the plugin with default options
await fastify.register(versionify, { prefix: "/~" });

Example with Options

import versionify from "@ynode/versionify";

// Register with a custom path
await fastify.register(versionify, {
    path: "/info"
});

Now the endpoint will be available at http://localhost:3000/info.

Release

To release a new version, use the included Makefile.

make release VERSION=1.2.3

This command will:

1. Check that npm and package.json exist.
2. Run npm version to update package.json and create a git tag.
3. Publish the package to npm.
4. Push the commit and tags to the git remote.
