Question 1

How do I query nested JSON arrays with gojq?

Accepted Answer

Use dot notation and array indexing for nested structures, as shown in the README with `parser.Query('[2].skills.[1]')` for accessing specific elements. For deeper nesting, chain queries using the nested query example provided.

Question 2

gojq vs Go's encoding/json package: which should I use?

Accepted Answer

gojq is better for quick extraction without defining structs, while encoding/json is ideal for type-safe unmarshaling into Go structs. gojq reduces boilerplate but lacks the type safety of standard parsing.

Question 3

Can gojq handle JSON keys with special characters like dots?

Accepted Answer

Yes, use single quotes around keys with special characters, as demonstrated in the README with `parser.Query("'hello.world'")` to access the `hello.world` key without confusion.

Question 4

How to install gojq in a Go project?

Accepted Answer

Install via `go get -u github.com/elgs/gojq`, then import it in your code. The library has no external dependencies, so setup is straightforward and minimal.

Question 5

Does gojq support JSONPath or full jq syntax?

Accepted Answer

No, gojq uses its own simple syntax similar to basic jq queries, focusing on dot notation and array indexing. It does not implement JSONPath or advanced jq features like filters or functions.

Question 6

What's the performance impact of using gojq?

Accepted Answer

gojq adds a lightweight layer over JSON parsing; for most use cases, performance is negligible, but in high-throughput applications, direct use of encoding/json might be more efficient due to lower overhead.
