sources

the source code of the deep-diff js library has been migrated to typescript . it remains unmaintained and contains some serious bugs that made it unreliable for this project .

• tag:v1.0.2 flitbit/diff
• tag:v1.0.2 flitbit/diff/tests
• tag:v1.0.5 @types/deep-diff

same interfaces have been exposed to maintain compatibility with the last version .

many thanks to the library author and all previous contributors !

usage

recommended to invoke via the wrapper method for simple cases :

import { deepDiff } from "datum-merge";
const datumDiff: Partial<MyType> = deepDiff<MyType>(target, source);

or use the existing library interfaces now with types :

import { diff, Diff, applyChange } from "datum-merge";
const simpleDiff: Diff[] = diff(target, source);
for (const dif of simpleDiff) { applyChange(target, null, dif); }

import { Diff, accumulateDiff, PreFilter, Accumulator } from "datum-merge";
const customDiff: Diff[] = accumulateDiff(target, source, prefilter, accum, orderIndep);

or for usage on browser environments:

<script src="https://unpkg.com/[email protected]/dist-diff/umd/deep-diff.min.js"></script>

see the readme in the original library for detailed examples .

datum-diff

module recently published as a standalone package datum-diff

works as a drop-in replacement for the package deep-diff

simply use datum-diff instead of the datum-merge libary in the examples above .

changes

• all functions and responses are typed
• lhs and rhs should be immutable ( had bug when orderIndependent=true )
• diff response should be immutable
• general code upgrades and variable cleanup
• avoid introducing any dependancies within module
• bundled package size is seven times smaller
