Parsing JSON in JavaScript: A Step-by-Step Guide
In more complex applications, developers may use external libraries to simplify the handling of JSON. These might include utilities for safe parsing, data validation, or transformation. While JavaScript’s built-in features are sufficient for most cases, third-party tools can help handle edge cases more gracefully. On the server side, JavaScript developers using Node.js frequently interact with JSON.

October 2, 2024Blazing fast XML parser to JSON for Node.js written in Rust
This appears to be almost an order of magnitude slower than xml-conv-json Package Time taken ---------------------------------- ---------- parser-xml2json (rust) 0.0661 s parser-xml2json (rust, no obj) 0.0649 s xml2js (js) 0.2056 s xml2json (js and c++) 0.1868 s xml-conv-json (c++) 0.0078 s xml-conv-json (c++ and JSON.parse) 0.0113 s EDIT: These benchmarks run on a 2013 MacBook Air 1.3 GHz i5 on macOS 10.12.3 on battery power, so YMMV. EDIT2: Thermal limiting seems to matter. By reordering the tests, the performance difference on my machine is noticeable: Package Time taken ---------------------------------- ---------- xml-conv-json (c++) 0.0066 s xml-conv-json (c++ and JSON.parse) 0.0077 s parser-xml2json (rust) 0.0708 s parser-xml2json (rust, no obj) 0.0710 s xml2js (js) 0.2128 s xml2json (js and c++) 0.2034 s More on reddit.com

August 2, 2023Async JSON parser/serialiser
Yielding (in the cooperative threading rather than generator sense) in node is a bit tricky, and got more tricky around Node 14, where I had to fix some unit tests because we discovered replacing an async method with a sync mock results in a noop for await, and so our expects and calls were in the wrong order. A SAX style parser like fast-json will get you incremental parsing but unless you throw some async code in on purpose the attempts to yield may get optimized away. You’ll need to wrap setImmediate or setTimeout(…,0) in a Promise to really force multitasking. Whether you write it or find a module that does is a separate question. More on reddit.com
