Flat Learning Curve
Convention-over-configuration, sensible defaults, opinionated APIs, and the Groovy language combine to make the Grails® framework easy to learn for Java developers.
On top of Spring Boot
The Grails framework is built on top of Spring Boot and leverages Spring Boot's time-saving features, such as Spring-powered dependency injection.
Smooth Java Integration
The Grails framework seamlessly and transparently integrates and interoperates with Java, the JVM, and existing Java EE containers.
Apache Groovy is a language for the Java platform designed to enhance developers' productivity. It is an optionally-typed and dynamic language but with static-typing and static compilation capabilities.
Seamless GORM Integration
The Grails framework seamlessly integrates with GORM, a data access toolkit that provides a rich set of APIs for accessing relational and non-relational data. GORM also includes implementations for Hibernate (SQL), MongoDB, Cassandra, and Neo4j.
REST APIs, REACT, ANGULAR
Developers can build plugins that extend and enhance the Grails framework, or they can access existing plugins published by a vibrant plugin community.
Technologies such as GSP, JSON Views, and Markup Views help developers effortlessly generate HTML, JSON, and XML.
The async features of the Grails framework aim to simplify concurrent programming. The framework's features include the concept of Promises, a unified event model, and the use of RxJava to write reactive logic.
The Grails framework is an open source Apache 2 License project.
The Grails framework relies on expressive domain-specific languages (DSLs) for validation, querying, markup rendering, and more.
Developers can access support at any time via IDEs and text editors, such as Intellij IDEA, Eclipse, Sublime, and Textmate.
