oasdiff VS openapi-diff

We will use an open-source GitHub action, oasdiff-action, based on the tool ‘oasdiff.’

Nice, Have you come across this tool oasdiff from the article? It may help with detect API breaking changes in swagger

While you might wish that pull request reviewers would spot any breaking changes, relying solely on this method is not certain and might lead to failure eventually. If you have OpenAPI/Swagger documentation for your APIs, these can be version-controlled and included in a CI pipeline. APISIX doesn't natively support direct integration with version control systems like Git for API specification changes. However, you can set up a process outside APISIX. Tools like Oasdiff or Bump can identify changes in API specs, and trigger a CI pipeline (add GitHub Action) that runs tests against the route endpoints in APISIX to ensure no breaking changes are introduced.

Now that we have a way to lookup our API’s behavior with Git, we can start testing for breaking changes between versions of our API. We’ll be using Optic (an open source tool I created) to do just that. If you are looking for other options I recommend https://github.com/OpenAPITools/openapi-diff or https://github.com/Tufin/oasdiff.

2. Delete the API at the sunset date or later

People seem to want such a process in order to prevent breaking-changes.

I wrote a diff tool for OpenAPI spec which supports detection of breaking-changes and I recently extended it to support this process and a bit more.

Now I'm looking for feedback.

Introducing our star player for detecting breaking changes: OpenAPI Diff. The good news? You can fire it up locally with Docker. Here’s how:

One option is to use OpenAPI to define the contracts. And then when you update the definitions, run something like https://github.com/OpenAPITools/openapi-diff to make sure there are no incompatibilities.
