WHAT IS GRAIL FRAMEWORK?
Grails is a web framework based on Groovy and Java which can be deployed into existing Java web servers, e.g., Tomcat or Jetty.
Grails allows you to quickly create web applications; its scaffolding capabilities let you create a new project within a few minutes. Grails is based on the convention over configuration idea which permits the application to auto-wire itself based on naming schemes (rather than utilizing the configuration files, e.g, XML files).
- Grails utilizes JavaEE as the architectural basis and Spring for organizing the application via dependency injection.
- The Grails framework allows for instance development without requiring any configuration. Just download Grails and you are ready to start. Grails accomplishes this by automatically giving the Tomcat web container and the HSQLDB database during development. If you deploy your Grails application later, you can use another web container or database.
- Grails is plug-in based and currently uses its own build system (Gant) but plans to migrate to Gradle. The Grails homepage provides several pre-defined plugins that extend the Grails framework.
- During the start of new development with Grails, you mainly use the command line to generate new user interfaces.
FEATURES OF GRAILS
Below are some benefits of Grails:
- Groovy Lineage: The Grails framework is based on Apache Groovy, a language for the Java platform designed to enhance developer productivity.
- Spring Boot Foundation: The Grails system is based on top of Spring Boot and uses Spring Boot’s time-saving features, such as Spring-powered dependency injection.
- Seamless Java Integration: The Grails framework flawlessly and straightforwardly incorporates and interoperates with Java, the JVM, and existing Java EE containers.
- Optimized Reloading Agent: The Grails system incorporates a development-time reloading agent that supports the dynamic reloading of code changes, in this manner diminishing the number of container restarts in the development environment.
- Built-In Testing Framework: The Grails framework’s built-in testing framework keeps up maintaining code quality all through the development process and reduces defects in the final product.
- Plugin Library: Developers can build plugins that extend and enhance the Grails framework, or they can access existing plugins published by a vibrant plugin community.
- Pragmatic Strategy: The Grails framework applies the “Don’t Repeat Yourself” (DRY) principle, thereby eliminating repetition and hidden bugs, and enabling faster and easier enhancements.
BENEFITS OF GRAILS
Below are some benefits of Grails:
- Increased Developer Productivity: Incorporating convention over configuration, the Grails framework eliminates much of the configuration effort typically required in building robust web applications.
- Faster Time to Market: The efficiency and precision of the Grails code mean faster development with fewer bugs and less code.
- Agility: Iterative development is a hallmark of the Grails framework because teams can carve out functionality in short sprints, with checkpoints and testing along the way.
- Reusability: The Grails plugin system enables code reuse across projects, allowing development teams to spend less time solving common web problems and more time implementing real business requirements.
- Low Maintenance: Foundational design assumptions eliminate the need for boilerplate code and account for an easier-to-navigate framework, thereby reducing maintenance complexity and project costs.
- Cost Savings: As an Open-Source framework, Grails can be broadly adopted and used with no vendor lock-in, contracts, license management, or run-time licensing fees.
- 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.
In the Software Frameworks category, Grails has a market share of about 0.1%. According to Indeed’s latest reports, Grails Developers are paid around $90k.
