Grails is an open source web application framework which uses the Groovy programming language. It is intended to be a high-productivity framework by following the “coding by convention” paradigm, providing a stand-alone development environment and hiding much of the configuration detail from the developer.
Grails is a powerful web framework for the Java platform aimed at multiplying developers’ productivity thanks to a Convention-over-Configuration paradigm, sensible defaults and opinionated APIs. It integrates smoothly with the JVM, allowing you to be immediately productive whilst providing powerful features, including integrated ORM, Domain-Specific Languages, runtime and compile-time meta-programming and Asynchronous programming.
key benefits of Grails
FLAT LEARNING CURVE
Convention-over-configuration, sensible defaults, opinionated APIs, and the Groovy language combine to make Grails easy to learn for Java developers.
ON TOP OF SPRING BOOT
Grails is built on top of Spring Boot and leverages Spring Boot’s time-saving features, such as Spring-powered dependency injection.
Apache Groovy is a language for the Java platform designed to enhance developer’s productivity. It is an optionally-typed and dynamic language but with static-typing and static compilation capabilities.
REST APIS, REACT, ANGULAR
Developers can build plugins that extend and enhance Grails, or they can access existing plugins published by a vibrant plugin community.
Grails relies on expressive domain-specific languages (DSLs) for validation, querying, markup rendering, and more.
