Hapi Starter Kit | Hapi based REST application boilerplate, uses async/await

Overview

A lean boilerplate application for building RESTful APIs (Microservice) in Node.js using hapi.js. Follows industry standard best practices, and uses latest async/await ES8 feature. Bring your own front-end. Plug-in your own Database.

Features

Feature	Summary
Uses latest ES8/ES2017 features (async/await)	Uses latest ES7 and ES8 features including async/await
Application Configuration via config	Node-config organizes hierarchical configurations for your app deployments. It lets you define a set of default parameters, and extend them for different deployment environments (development, qa, staging, production, etc.).
Auto Documentation via hapi-swagger	This will self document the API interface. You can also tests your APIs using the Swagger interface.
Unit and Integration Tests via Mocha with async/await	Demo unit and integration tests using latest ES7/ES8 features.
Code Coverage via istanbul	Supports code coverage of ES8 code using istanbul and mocha. Code coverage reports are saved in coverage/ directory post yarn test execution. Open coverage/lcov-report/index.html to view coverage report. yarn test also displays code coverage summary on console. Code coverage can also be enforced overall and per file as well, configured via .istanbul.yml
Logging via bunyan	Bunyan is simple and fast JSON logging library. Logs timestamp, machine name and process ID and most importantly makes it really easy to parse logs as it logs in JSON format. You can selectively turn on/off logs by setting log level via LOG_LEVEL env variable.
Code Linting via Standard	JavaScript code linting is done using ESLint - a pluggable linter tool for identifying and reporting on patterns in JavaScript.
API parameter validation via joi	Validate body, params, query, headers and cookies of a request (via middleware) and return a response with errors; if any of the configured validation rules fail. You won't anymore need to make your route handler dirty with such validations.
Application monitoring via New Relic	Set NEW_RELIC_APP_NAME and NEW_RELIC_LICENSE_KEY environment variables in production environment to get metrics in New Relic Dashboard
Pre-commit hooks via husky	Runs lint and tests before any commit is made locally, making sure that only tested and quality code goes through
Uses Sinon for spies, stubs and mocks	Standalone and test framework agnostic JavaScript test spies, stubs and mocks
Uses nock for mocking http requests in integration tests	Nock is an HTTP mocking and expectations library. It can be used to test modules that perform HTTP requests in isolation.
Uses yarn over npm	Uses new released yarn package manager by facebook. You can read more about it here
Docker compatible	Docker and Docker Compose files to develop and deploy via Docker
Uses EditorConfig	EditorConfig helps developers define and maintain consistent coding styles between different editors and IDEs

Requirements

• node.js >= 8.4.0
• yarn >= 0.27.5
• docker
  • Docker is optional and is required only if you want to develop and deploy using Docker

Getting Started

# Install dependencies
$ yarn

# Start Server
# Set environment variables defined in `config/custom-environment-variables.json` like `OPEN_WEATHER_API_KEY=xxx`
$ yarn start

# Try GET /ping to make sure server is up
$ curl http://localhost:3030/ping

# Run Tests
$ yarn test

Docker

Development

# copy sample.dev.env to dev.env
$ cp bin/sample.dev.env bin/dev.env

# Start Server
$ bash bin/development.sh

Tests

# copy sample.test.env to test.env
$ cp bin/sample.test.env bin/test.env

# Run Tests
$ bash bin/test.sh

Environment Configuration

config is used to configure application.

• Default values of environment variables, which are common across all environments can be configured via config/default.json
• Values specific to a particular environment can be set by creating a file with same name in config directory. Like config/test/json for test environment.
• config/custom-environment-variables is used to read values from environment variables. For ex. if APP_PORT env var is set it can be accessed as config.get('app.port'). You can read more on custom environment variables here.

More Tasks

# Run lint
yarn lint

Deployment

• Simply set environment variables defined in bin/sample.dev.env in your own environment (AWS, Heroku etc) and yarn start

Docker

• Build the docker image
  • docker build -t hapi-starter-kit-oss .
• Start Docker Container
  • docker run -d -p 3030:3030 --name hapi-starter-kit-oss hapi-starter-kit-oss

Documentation

• hapi-swagger self documents all the APIs.
• Visit http://localhost:3030/documentation to access the documentation after starting the server.

Miscellaneous

• To turn off logs getting logged via good-console in development environment, remove it from plugins.js
