Package Exports
- json-escaping
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-escaping) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
JSON-escape
Fast JSON string escaping in JS.
It is faster to escape small JSON strings manually than using native
JSON.stringify().
The main focus is a very fast check for strings that do not need any escaping while also improving escaping itself or at least not to go below JSON.stringify.
Benchmarks
Running the benchmarks (npm run benchmark) show the benefits:

The benchmarks ran on Node.js 10.2.1 using a Lenovo T450s with an i7-5600u. The "longer" benchmarks are worst case benchmarks.
