What you get!

  • Express.js - Fast, unopinionated , minimalist web framework for Node.js

  • Babel.js - Use new syntax, right now without waiting for support

  • Pino - Extremely fast node.js logger, inspired by Bunyan. It also includes a shell utility to pretty-print its log files

  • dotenv - Loads environment variables from .env for nodejs projects

  • ESLint - a pluggable linting utility for JavaScript and JSX

    Choose from the following ESLint lint rules:

    • Airbnb - A mostly reasonable approach to JavaScript
    • Prettier - Prettier is an opinionated code formatter
  • Swagger - is a simple yet powerful representation of your RESTful API

  • SwaggerUI - dynamically generate beautiful documentation and sandbox from a Swagger-compliant API

API Validation

Simply describe your APIs with Swagger and automagically get for free:

  • Interactive documentation
  • API validation

Interactive API Doc

API Validation!

Oops! I the API caller forgot to pass a name field, no stress, we've got this!

Structured Logging

Structured logging out of the box!

raw

pretty

Structured logging pretty printed by default - great for dev!
