Coldbox Relax LogoColdBox Relax Moldule v3.0 has been officially released, which includes native support for the OpenAPI/Swagger specification, in addition to a variety of feature upgrades and enhancements.

Version 3.0 makes the OpenAPI/Swagger specification the default documentation format for describing your APIs, while deprecating the Relax programmatic DSL ( scheduled EOL is v4.0 ). In addition, the release includes a complete overhaul of the user interface and Relax API Test Tool, to provide users with a seamless experience for documenting, viewing, testing and exporting in a variety of formats.

The OpenAPI specification offers a convenient and portable way to describe your API, its requirements, parameters, and data conventions. You may also choose to use this to describe your API in the form of HTTP OPTIONS responses to fulfill CORS requirements or to allow rich hypermedia documentation for your consumers.

What can you do with Relax?

  • Define your ReSTful services via the OpenAPI/Swagger JSON syntax
  • Use the "Relaxer" API Test tool to test your RESTful web service enpoints
  • Use the "Relaxer" API Test too to test against ANY RESTful service
  • Keep a history of your latest Relaxed test requests so you can rebuild your request and test again
  • Programmatic DSL for configuration of your RESTful services (Deprecated as of v2.3)

Relax also allows you to import an OpenAPI/Swagger JSON specification in to your defined apiResources directory, export normalized schema (JSON) for other services and also four export formats:

  • HTML
  • PDF
  • WikiText
  • TRAC Format

Markdown export is also planned for an upcoming minor release.

By convention, Relax looks for supported formats in the following order (note that the top-level file shares the name of the parent directory):

  1. myResourceDirectory/myapi/myapi.json - JSON OpenAPI schema
  2. myResourceDirectory/myapi/myapi.yaml - YAML OpenAPI schema
  3. myResourceDirectory/myapi/Relax.cfc - Relax programmatic DSL (deprecated)

To install Relax, use CommandBox:

box install relax

Relax comes with three example API's which are configured by default:

  • Swagger Petstore - The swagger Petstore API example, which is described using the OpenAPI/Swagger specification
  • Forgebox API - Version 2 of the Forgebox API, which is described through the, now-deprecated, RelaxDSL specification.
  • MyAPI - Another example, using the RelaxDSL specification.

Both Forgebox and MyAPI may be exported from within the interface in to a normalized Swagger JSON schema, while the Petstore example provides and complete example of using a nested file structure to contain different parts of your API documentation.

If you'd like to play with Relax, here are a few lines of script, which will create an app skeleton, install the module, and start a server. Simply navigate to the /relax path, once your browser opens, to view the new changes.


mkdir relaxtest && cd relaxtest
box coldbox create app name=relaxTest
box install relax
box server start --rewritesEnable

or from within the CommandBox shell:


mkdir relaxtest --cd
coldbox create app name=relaxTest
install relax
server start --rewritesEnable

Inherited a CFML Application With Few Tests? Here’s Where to Start!

Inherited a CFML Application With Few Tests? Here’s Where to Start!

You need to change an application that has been running for years.

It might be a ColdFusion customer portal, a Lucee application supporting internal operations, or a CFML system your team is preparing to modernize. People depend on it, but some of its behavior lives in old tickets, scattered documentation, and the memory of whoever has supported it longest.

Now a release is approaching. You know more testing would help. The difficult part is deciding where to begin without putting every other priority on hold.

Start with one important workflow and build evidence around what it needs to do.

Your ColdFusion Upgrade Passed. Did Your Business Workflows?

The server restarted. The administrator shows the expected version. Your homepage loads, and a few familiar screens look fine.

Would you tell the business the upgrade is complete?

Consider an illustrative scenario: a customer submits an order after an upgrade. The application saves it and displays a confirmation page. But the confirmation email never arrives, and the scheduled process that sends the order to fulfillment has not completed.

From the browser, the transaction...
