Question 1

How does SJSON compare to Go's standard encoding/json for updating JSON?

Accepted Answer

SJSON is much faster for targeted updates using dot-notation paths without full unmarshaling, but encoding/json offers better type safety and error handling for complex structures. Use SJSON when speed is critical and data is well-formed.

Question 2

How to append an element to a JSON array with SJSON?

Accepted Answer

Use the '-1' key in the path, like 'array.-1', to append a value. For example, sjson.Set(json, "friends.-1", "newFriend") adds to the end of the array, as shown in the README examples.

Question 3

What happens if I try to set a value with an invalid path in SJSON?

Accepted Answer

Invalid paths may return an error, but invalid JSON doesn't panic and can return unexpected results. Always ensure your JSON is well-formed and paths are correct to avoid silent failures.

Question 4

Can SJSON handle JSON objects with numeric keys?

Accepted Answer

Yes, use the colon syntax, like 'users.:2313.name', to force numeric object keys in paths. This is documented in the README for cases where keys are numbers but should be treated as object properties.

Question 5

Is SJSON good for real-time web servers modifying API responses?

Accepted Answer

Yes, its high performance and low memory overhead make it ideal for real-time applications. Benchmarks show fast operations, but ensure error handling is added since invalid JSON can cause issues.

Question 6

Does SJSON support batch updates or multiple changes at once?

Accepted Answer

No, SJSON operates on single paths per call; for multiple updates, you need to chain calls, which might be less efficient than batching with other libraries or custom solutions.
