@swagger-api/apidom-json-pointer

This package implements JSON Pointer (RFC 6901) for ApiDOM structures rather than plain JSON. The learning curve is steep because you need to understand both ApiDOM's tree structure and JSON Pointer syntax. Documentation is minimal—there's a basic README with one example, but no comprehensive guide on common patterns or edge cases. You'll spend time reading source code to understand what's actually supported.

Error messages are cryptic when pointers don't resolve or when you pass incorrect ApiDOM structures. Debugging requires console.logging the ApiDOM tree to understand its shape, which slows development. The package works reliably once you figure it out, but getting there takes effort. Stack Overflow has virtually no coverage, and GitHub issues are sparse, so you're mostly on your own.

The API itself is straightforward once understood—evaluate() takes a pointer string and ApiDOM element. It integrates well with other @swagger-api packages if you're already in that ecosystem, but feels overengineered if you just need JSON Pointer for regular JSON objects.

This package is part of the ApiDOM ecosystem and provides JSON Pointer (RFC 6901) evaluation specifically for ApiDOM structures rather than plain JSON objects. In practice, this means you need to understand both JSON Pointer syntax AND ApiDOM's element structure, which adds a learning curve. The API itself is straightforward once you grasp that concept - you evaluate pointers against ApiDOM trees and get back ApiDOM elements.

The TypeScript support exists but feels incomplete. Type definitions are present, but you'll often find yourself checking whether results are undefined or specific ApiDOM element types. Error messages when pointers fail to resolve are minimal - you typically just get undefined back rather than actionable feedback about what went wrong in your pointer expression.

Documentation is sparse outside of the main ApiDOM docs. You're better off looking at the broader @swagger-api/apidom-reference examples to understand practical usage. The package works reliably for its intended purpose, but it's really only valuable if you're already deep in the ApiDOM ecosystem for OpenAPI/AsyncAPI manipulation.

This package does exactly what it says: evaluates JSON Pointer expressions against ApiDOM structures. If you're already deep in the Swagger/OpenAPI ecosystem using ApiDOM, this works as expected. The API is straightforward - you evaluate pointers and get back elements. However, the learning curve is steeper than it should be because the documentation assumes you already understand ApiDOM's element structure.

Error messages are decent when pointers are malformed, but when you hit edge cases with complex ApiDOM structures, debugging becomes frustrating. The package lacks practical examples showing real-world OpenAPI traversal scenarios. You'll spend time reading ApiDOM core docs to understand what you're actually working with. Community support is sparse - GitHub issues get responses but Stack Overflow has virtually no coverage.

For day-to-day use, it's reliable once you understand the ApiDOM element model, but getting there takes effort. If you just need standard JSON Pointer evaluation, json-pointer package is much simpler. This is really only worth it if you're committed to the ApiDOM ecosystem for advanced OpenAPI manipulation.
