Question 1

How does Lazy JSON handle large JSON files without running out of memory?

Accepted Answer

Lazy JSON uses Laravel's lazy collections to parse JSON incrementally, loading only small chunks into memory at a time. This allows it to process files of any size while consuming minimal RAM, as highlighted in the README with examples of memory-efficient processing.

Question 2

Can I use Lazy JSON with Laravel's HTTP client to process API responses?

Accepted Answer

Yes, Lazy JSON directly supports Laravel HTTP client responses as a source. You can pass an Illuminate\Http\Client\Response object to fromJson(), and it will lazily parse the JSON body without loading it entirely into memory.

Question 3

What's the difference between Lazy JSON and using json_decode with generators?

Accepted Answer

While both approaches can be memory-efficient, Lazy JSON offers a higher-level abstraction with built-in dot-notation extraction and seamless Laravel integration. json_decode with generators requires manual implementation for streaming and lacks the convenient syntax and broad source support.

Question 4

How to extract specific fields from a nested JSON structure with Lazy JSON?

Accepted Answer

Use the dot-notation syntax when calling fromJson(), such as 'results.*.location.city'. This instructs Lazy JSON to parse only the city fields from each result, ignoring the rest of the JSON to save memory and processing time.

Question 5

Is Lazy JSON suitable for processing real-time streaming JSON data?

Accepted Answer

Lazy JSON can handle streaming sources like PSR-7 streams, but its performance depends on the underlying JSON Parser. For high-throughput, real-time streams, you should benchmark it against specialized streaming parsers to ensure it meets latency requirements.

Question 6

Does Lazy JSON support error handling for malformed JSON?

Accepted Answer

Error handling is delegated to the JSON Parser package. While not detailed in the Lazy JSON README, parsing errors typically throw exceptions that need to be caught in your code, so refer to the JSON Parser documentation for specifics.
