One of the patterns we've seen repeat itself in this publication is that static error- and style-checking tools emerge quickly after a new language gains popularity. These tools are generically known as linters — after the classic and beloved Unix utility lint, which statically analyzes C code. We like these tools because they catch errors early, before code even gets compiled. The latest instance of this pattern is Spectral, a linter for YAML and JSON. Although Spectral is a generic tool for these formats, its main target is OpenAPI (the evolution of Swagger) and AsyncAPI. Spectral ships with a comprehensive set of out-of-the-box rules for these specs that can save developers headaches when designing and implementing APIs or event-driven collaboration. These rules check for proper API parameter specifications or the existence of a license statement in the spec, among other things. While this tool is a welcome addition to the API development workflow, it does raise the question of whether a non-executable specification should be so complex as to require an error-checking technique designed for programming languages. Perhaps developers should be writing code instead of specs?
