Phonebook API

This simple application was created for the sole purpose of being a portfolio application. It serves no real world purpose outside of this scope. The application takes the form of a NodeJS application that utilises TypeScript and provides a RESTful Express API. It integrates with MongoDB as the datasource of choice and is hosted on Heroku. Deployments are automated on a push to master through Travis CI and code analysis is provided through SonarCloud. All logging is centralised on Loggly with appropriate correlation ID's, either provided or generated, to trace requests through the system.

Get Started

You can get started with your own locally hosted instance of this application quite quickly and painlessly.

$ git clone https://github.com/ToeFungi/phonebook-api.git
$ cd phonebook-api
$ npm i

You'll need to setup your environment variables in a .env file that should be at the top level of your application. You can find precisely what the required environment variables are documented further down in the README OR you can jump there now.

Endpoints

There are a number of endpoints that are available through this API. In essence, a user should be able to create an account, login with that account, create, get, update and delete their private contacts list as will as query the health status of the API. Below is a more descriptive explanation on each endpoint.

Insomnia and Postman Workspaces

You can find workspaces for both Insomnia and Postman within the repository under collections. You'll be able to import these workspaces and test the below API endpoints for yourself. Alternatively, if you are cloning this repository then you can use the local workspace instead and test everything locally!

Contacts

The contacts endpoints are everything to do with how contacts are handled. The create, read, update and delete endpoints will be documented here and briefly explained. Please use the workspaces to test these endpoints.

Get a Contact

The retrieval of a specific contact by ID is available on a GET endpoint and the contact's ID should be provided in the path. This will then return a JSON object along with a 200. If no contact can be found corresponding to the given ID, then a status of 404 will be returned with a JSON body that includes a message indicating that the contact could not be found.

[GET] /contacts/:contactId

Response 200

{
  "email": "[email protected]",
  "mobile": "0828097121",
  "contactId": "5e4fe9c61c9d440000f3af57",
  "nickname": "Johnny",
  "lastname": "Smith",
  "firstname": "John",
  "mobileIDC": "+27"
}

Response 404

{
  "error": "NOT_FOUND",
  "message": "Contact could not be found with the provided ID"
}

Get All Contacts

You can retrieve all of the contacts available by not specifying an ID and this will return a JSON body that contains an array of contacts available. The response code will be a 200.

[GET] /contacts

Response 200

[
  {
    "email": "[email protected]",
    "mobile": "0828097121",
    "contactId": "5e4fe9c61c9d440000f3af57",
    "nickname": "Johnny",
    "lastname": "Smith",
    "firstname": "John",
    "mobileIDC": "+27"
  }
]

Health

The objective of the health endpoint is to ensure that the external dependencies of the application are healthy and be reached. As such, the application is considered healthy if the database and health endpoint can be reached.

Get Health

You can query the health status of the application conveniently on the following endpoint.

[GET] /health/health

Response 200

{
  "healthController": "healthy",
  "databaseConnection": "healthy"
}

Follow Development

This project has a Trello board! You can follow development, see what's blocked and what's in progress. See what the upcoming features are and the work required to complete each task along with it's relevant acceptance criteria.

Environment Variables

The following table represents the variables that are required to be in the environment for the application to use at run time.

Name	Description
PORT	The port that the application will be exposed on once hosted.
DATABASE_URL	The URL to be used to connect to the given database.
DATABASE_NAME	The name of the database that will be used.
DATABASE_ENGINE	The database engine that the application will be connecting to.
DATABASE_USERNAME	The username credential to access the database.
DATABASE_PASSWORD	The password credential to access the database.
LOGGER_LEVEL	The level of logging required. info/debug/trace are most common.
LOGGER_SERVICE	The name for the basic application level logger which will be used to spawn all child loggers.
LOGGER_LOGGLY_TOKEN	The token used for authentication on Loggly
LOGGER_LOGGLY_SUBDOMAIN	The subdomain used for authentication on Loggly

Testing

This project uses the mocha testing framework to run all tests. It makes use of the chai assertion library as well as chai-as-promised for all asynchronous assertions. For stubbing, the project makes use of sinon. All of these libraries are configured in test/support/setup.spec.ts. This README includes a badge indicating the current total code coverage and more details are available on Sonar itself.

To run these tests locally, the below commands can be used.

$ npm audit
$ npm run test
$ npm run coverage
$ npm run lint

Logging

This application has centralised logging using Loggly and all production logs by default are sent through to it.
