# Dotkernel API 1.0.0 Released

> Note: Dotkernel API has come a long way since this post was created; a newer version is documented separately.

Dotkernel API 1.0.0 was just released.

## What is Dotkernel API?

It is a Zend Expressive 3 application aiming to help developers quickly and efficiently develop an API.

## How Does It Work?

Under the hood, it uses the following libraries:

- `ezimuel/zend-expressive-api` - skeleton application on which this API is based
- `dotkernel/dot-annotated-services` (^1.1) - for handling dependency injection in your services
- `dotkernel/dot-console` (^0.1.1) - for developing console applications
- `dotkernel/dot-errorhandler` (^1.0) - which provides customizable error logging
- `dotkernel/dot-mail` (^1.0) - for sending emails via SMTP
- `zendframework/zend-expressive-authentication-oauth2` (^1.0) - for OAuth2 authentication
- `zendframework/zend-expressive-authorization-rbac` (^1.0) - for role-based permissions
- `zendframework/zend-expressive-twigrenderer` (^2.4) - for composing email bodies
- `dasprid/container-interop-doctrine` (^1.1) - database abstraction layer
- `tuupola/cors-middleware` (^0.9.4) - for automatically sending CORS headers with each request
- `swagger-api/swagger-ui` (^3.22) - for creating OpenAPI 3 documentation

## What Does It Offer?

Out-of-the-box, Dotkernel API provides the following features:

- Secure authentication via OAuth2
- Two user roles: admin and member
- Admin users are allowed to manage any user account
- Members are allowed to manage only their own accounts
- OpenAPI 3 documentation - also an interactive interface that developers can use to integrate your API
