@n1ru4l/json-patch-plus

This is a slimmed version of jsondiffpatch. All the code is taken from the jsondiffpatch repository, slimmed down, slightly altered and converted to TypeScript.

Huge thanks to @benjamine, who did all the heavy work!

jsondiffpatch is a replacement for json-patch that produces more efficient patches!

@n1ru4l/json-patch-plus has the following changes:

• Full ESM support
• Remove Node.js runtime dependencies introduced through loggers
• Remove class wrapper structures (make code less abstract and smaller)
• Remove text diffing
• Only generate and apply patch deltas (no reversing and visualization)
• Exclude unnecessary data from patch deltas (previous value is replaced with null)

For a full description of the delta format please refer to the jsondiffpatch docs

Install Instructions
