Ivory API Service

Digital service to support the Ivory Act.

Environment variables

(Be sure to describe any environment variables here by maintaining a list like this)

name description required default valid notes
NODE_ENV Node environment no dev,test,prod
PORT Port number no 3010

Prerequisites

Node v14+

Running the application

First install the dependencies & build the application using:

$ npm install

Now the application is ready to run: $ npm start or $ node index.js

To run the application in Docker

$ npm run docker:build followed by $ npm run docker:run

Project structure

Here's the default structure for the project files.

  • server
    • plugins
    • routes
    • config.js
    • index.js (Exports a function that creates a server)
  • test
  • README.md
  • index.js (startup server)

Config

The configuration file for the server is found at server/config.js. This is where to put any config and all config should be read from the environment. The final config object should be validated using joi and the application should not start otherwise.

A table of environment variables should be maintained in this README.

Plugins

hapi has a powerful plugin system and all server code should be loaded in a plugin.

Plugins live in the server/plugins directory.

Logging

The good and good-console plugins are included and configured in server/plugins/logging

The logging plugin is only registered in when NODE_ENV=dev.

Error logging for production should use errbit.

Routes

Incoming requests are handled by the server via routes. Each route describes an HTTP endpoint with a path, method, and other properties.

Routes are found in the server/routes directory and loaded using the server/plugins/router.js plugin.

Hapi supports registering routes individually or in a batch. Each route file can therefore export a single route object or an array of route objects.

A single route looks like this:

{
  method: 'GET',
  path: '/hello-world',
  options: {
    handler: (request, h) => {
      return 'hello world'
    }
  }
}

There are lots of route options, here's the documentation on hapi routes

Testing

lab and code are used for unit testing.

See the /test folder for more information.

Linting

standard.js is used to lint both the server-side and client-side javascript code.

It's defined as a build task and can be run using npm run lint.
