Generate

We have light-codegen to support project scaffolding for all the frameworks provided by Light platform. We believe that for enterprise scale and microservices, you have to adopt design first. There are numeric ways to use light-codegen and here we are just using it as command line cli tool.

This project will be updated constantly when a new version of light-4j framework is released or any updates in light-codegen. Both swagger petstore and openapi petstore projects are our test beds for light-rest-4j.

Here is the command line to generate this project from model-config directory. It assumes that you have light-example-4j cloned in the same working directory and petstore directory is removed or renamed. If you have changed the specification and want to regenerate the project, it is better to generate into another folder and then do a full text comparison to merge the new project into the old project.

cd ~/networknt
java -jar light-codegen/codegen-cli/target/codegen-cli.jar -f swagger -o light-example-4j/rest/swagger/petstore -m model-config/rest/swagger/petstore/2.0.0/swagger.json -c model-config/rest/swagger/petstore/2.0.0/config.json

The cli tool needs to specify:

• -f swagger - choose rest framework that support Swagger 2.0 specification for the generator
• -o output - choose the output folder for the generated project
• -m model - choose the model definition file or IDL spec as it is design driven generator
• -c config - choose config file to control how the project is generated

For information on how to use light-codegen, please check out the getting started. The detailed document can be found at tools section.

With the project generated, the next step, we are going to build and start the server.
