Allows you to better understand what's going on with your application and how to optimize performance and other things in production. Nuxt 2 users can use this version.

Features

• Default NodeJS metrics exported through the prometheus middleware
• Custom metrics about pages render time and external request consumption time
• Health check middleware

Default routes that you can customise via the module options

• /metrics - prometheus metrics
• /health - health check

Installation

Install package via a package manager:

# using nuxi, it automatically appends the module in your nuxt.config
npx nuxi@latest module add prometheus

# using npm
npm install @artmizu/nuxt-prometheus

# using yarn
yarn add @artmizu/nuxt-prometheus

# using pnpm

Add it to a modules section of your nuxt config:

export default {
  modules: ['@artmizu/nuxt-prometheus']
}
