Grails is a very powerful and high productivity framework meant for Java Virtual Machine (JVM). It follows the 'coding by convention' paradigm. This allows Grails-based applications to hide the Grails developer's configuration details and provide a standalone and ready-to-use development environment. Grails do not have an XML configuration. Its functionality can be accessed through mixins. With Grails, developers can use some of the features of Java, such as Spring and Hibernate, under one single interface. Development with Grails is efficient, easy, and quick due to the automatic reload of resources and a web server provided by Grails. Grails was developed to provide an integrated development environment to Java and Groovy developers to build web-based applications.
Learn more about Grails
Grails was initially released in October 2005 and was developed by Graeme Rocher. Grails has been written in Groovy. The latest version of Grails was released on 8th April 2021, version 4.0.10. Grails can be used on cross platforms and have been licensed by Apache. Grails uses the paradigm of MVC. Thus, it has controllers, views, tag libraries and models.
The domain model of Grails is connected using Grails Object Relational Mapping (GORM) to the database. You need to create a domain class to persist it with Grails.
The views in Grails are saved in the Book Controller. Grails is known to support GSP and JSP. For Grails to recognize the file as view, the developers need to save it in the above location.
The role of the Controller in Grails is like the MVC model. It is used to control and implement the behavior of web pages and web applications. A controller is needed to be created in Grails using the 'grails create-controller Book' command. Only after saving will Grails recognize a Controller.
Grails has numerous tag libraries, all of which are dynamic. Grails also let the developers create their customized tag libraries. Once created, the developer can reuse that library as many times as they desire.
Important features of Grails
Grails uses sensible defaults and Groovy language, which makes it very easy to understand. To top that, the convention over the configuration method of Grails is the cherry.
Grails is developed by adding layers to the Spring Boot. This gives Grails all the amazing features Spring Boot has.
Groovy is a dynamic programming language that allows developers to do static compilation. This feature of Groovy makes Grails very easy to use.
Grails can be very smoothly integrated with JVM, Java EE and Java. This makes programming seamless and transparent.
- REST APIs, React, Angular
Grails allows its user to actively build REST APIs. It also allows the inclusion of Angular and React in the application.
Grails enables the developers to create plugins that can extend the framework. Grails also has a list of plugins available for the enhancement of applications.
