$ grails create-restapi [OPTIONS] NAMEcreate-restapi
Purpose
The create-restapi command is a fundamental step in Grails application development, specifically tailored for creating Grails applications designed to serve as RESTful APIs. When invoked, this command generates a Grails application with a user-specified name and configures it to be a REST API. Subsequently, it creates a subdirectory based on the provided application name within the directory where the command is executed.
Usage
To create a Grails RESTful API, use the following command:
-
NAME: The desired name for the Grails plugin with a web layer.
Options
The create-restapi command accepts the following options:
-
NAME: The desired name for the REST API application. -
-f, --features=FEATURE[,FEATURE…]: Specifies the features to include. Available options include h2, scaffolding, gorm-hibernate5, spring-boot-starter-jetty, springloaded, spring-boot-starter-tomcat, micronaut-http-client, cache-ehcache, hibernate-validator, postgres, mysql, cache, database-migration, grails-gsp, hamcrest, gorm-mongodb, assertj, mockito, spring-boot-starter-undertow, micronaut-inject-groovy, github-workflow-java-ci, jrebel, testcontainers, sqlserver, grails-console, views-markup, asset-pipeline-grails, views-json, gorm-neo4j, asciidoctor, embedded-mongodb, grails-web-console, logbackGroovy, mongo-sync, shade, geb, properties. -
-g, --gorm=GORM Implementation: Specifies the GORM Implementation to configure, with options like hibernate, mongodb, neo4j. -
-h, --help: Displays the help message and exits. -
-i, --inplace: Creates a service within the current directory. -
--jdk=<javaVersion>: Specifies the JDK version for the project. -
-s, --servlet=Servlet Implementation: Specifies the Servlet Implementation, with choices including none, tomcat, jetty, undertow. -
-t, --test=TEST: Specifies the test framework, with options such as junit, spock.
These options allow you to customize your Grails REST API application according to your specific requirements and preferences.
Examples
To illustrate its usage, here are some examples:
-
Create a REST API application named "bookstore":
$ grails create-rest-api bookstore $ cd bookstore -
Create a REST API application directly in the current directory:
$ mkdir bookstore $ cd bookstore $ grails create-rest-api --inplace -
Customize the REST API application by adding specific features (available since Grails 3.1):
$ grails create-rest-api bookstore --features github-workflow-java-ci,asciidoctor -
Create a minimal Grails REST API application:
grails create-rest-api minimal-apiThis command will create a minimal Grails REST API application named "minimal-api" with default settings, ideal for starting a new REST API project.
-
Create a REST API application with support for PostgreSQL and specific features:
grails create-rest-api postgres-api --features postgresThis command will generate a Grails REST API application named "postgres-api" configured to use PostgreSQL as the database. It’s suitable for developing REST APIs with PostgreSQL as the data store.
-
Create a REST API application with in-place development:
grails create-rest-api inplace-api --inplaceThis command will create a Grails REST API application named "inplace-api" within the current directory, allowing for in-place development and integration with an existing project.
These examples demonstrate various scenarios for using the create-rest-api command to create Grails REST API applications. You can customize the REST API application by specifying features, database configurations, and development options to meet your project’s specific requirements.
