Spectral, a tool designed for API governance, has introduced a new core function called "or" to enhance its customizable linting rules, allowing API teams to maintain quality while catering to flexibility and decentralized decision-making. Core functions in Spectral serve as the foundation for creating rules by encapsulating logic like property existence checks or value comparisons and can be combined with JSONPath expressions to enforce standards in OpenAPI, Arazzo, or AsyncAPI documents. The new "or" function is particularly useful for asserting that at least one of several specified properties must exist, which is beneficial for scenarios where multiple validation paths are acceptable, such as ensuring documentation for API schemas without enforcing a standard format. This addition exemplifies the tool's evolution, thanks in part to community contributions like those from Clyde Cutting, which help make Spectral a more powerful and practical solution for API governance. Users are encouraged to update to the latest version of Spectral to utilize the "or" function in their rulesets, enhancing their ability to enforce schema documentation, naming conventions, or structural flexibility.
