getUpdatedFormFields

getUpdatedFormFields computes the difference between the initial form values and the current values, returning only the changed fields for a minimal PATCH payload.

Import


import { getUpdatedFormFields } from "@phpcreation/frontend-crud-react-nextjs-bundle/utils/getUpdatedFormFields";

Usage


import { getUpdatedFormFields } from "...";
 
const onSubmit = async (currentValues) => {
  const diff = getUpdatedFormFields(initialValues, currentValues);
 
  if (Object.keys(diff).length === 0) {
    toast("No changes to save.");
    return;
  }
 
  await apiPatch(`/entities/${id}`, diff);
};

Parameters

Param	Type	Description
`initial`	`Record<string, unknown>`	Values at form load time
`current`	`Record<string, unknown>`	Current form values

Returns

An object containing only the fields that have changed values.

Edge Cases

Array fields (many-to-many): compared by value equality, not reference
Empty string vs null: treated as equivalent (no change reported)
undefined fields: excluded from the diff
