OpenAPI to Ballerina code generator

You can use the existing OpenAPI/Swagger files to generate connectors and services in Ballerina code. For details, see the OpenAPI to Ballerina Code Generator.

API documentation generator

As you develop new connectors, remote functions in connectors and other functions that you want to share with others, it’s important to add API documentation that describes each entity and how it’s used. Ballerina provides a framework called Docerina that generates API documentation from the annotations in your Ballerina files. You can check it out here.

You can generate docs for a Ballerina file or module using the following command:

./ballerina doc [<ballerina-file>|<module-name>]

Test framework

Ballerina provides a testing framework called Testerina that you can use to test your programs. You can check it out here.

You can test a Ballerina file or module using the following command:

./ballerina test [<ballerina-file>|<module-name>]


Ballerina Language Specification supports a set of experimental features such as _transactions_ syntax. In order to be compatible with the experimental features and for supporting language intelligence in VSCode Plugin, enable the Allow Experimental option in user settings.
