Usage

1// Original document / object. 2const doc = { 3 a: 'b', 4 c: { d: 'e', f: 'g' }, 5 h: { i: 0 } 6}; 7 8// JSON merge patch to apply. 9const patch = { 10 a: 'z', 11 c: { f: null } // null marks deletions. 12}; 13 14// Apply the patch. 15const patchedDoc = mergePatch(doc, patch); 16 17// tiny-merge-patch complies with the RFC specification. 18assert.deepEqual(patchedDoc, { 19 a: 'z', 20 c: { d: 'e' }, 21 h: { i: 0 }, 22}); 23 24// Additionally, it does not mutate the original document... 25assert(patchedDoc !== doc); 26 27// ...nor its content... 28assert(patchedDoc.c !== doc.c); 29 30// ...but recycles what it can. 31assert(patchedDoc.h === doc.h);

Alternatives

All are in-place. To avoid mutations of the original object, one can deep-clone beforehand, but it can be expensive. At the contrary, tiny-merge-patch does not alter any of its arguments—but recycles what it can. Recycling also allows efficient strict identity-based memoization (used by React's PureComponent for example).

All of the above libraries also embed additional functionalities, such as patch generation from two objects or merge of patches. tiny-merge-patch only focuses on the IETF standard and on patch applications.

(None of the above libraries are particularly big. Still, tiny-merge-patch is smaller if you only need to apply patches. It is also worth mentioning that unlike JSON patches, there is no way to implement merge of merge patches that reliably preserves deletion.)
