APIs with REST Builder
REST Builder is a code generation tool that makes it easy for you to take your local APIs and make them available on the web. It uses the OpenAPI Specification to generate REST and GraphQL APIs.
REST Builder uses the configuration you define in rest-config.yaml and rest-openapi.yaml files to generate most of the code necessary for your API to work all at once. You configure class names and where to put the code, and REST Builder generates all of the necessary files. Then you add your implementation logic.
You run REST Builder using the Gradle task buildREST from your impl module in a Liferay workspace. Once configured, it generates all the scaffolding code, interfaces, and even resource classes ready for implementation.
