json-omit

Json manipulation node module.

Available functions :

• omit(originialObject, ...paths) : copies the originalObject and deletes attributes specified in ...paths before returning the result
• clone(originalObject) : retruns a deep copy of the originalObject

Examples

const { omit, clone } = require("json-omit");

omit(originalObject, ...paths)

omit attributes or nested attributes :

const orignialObject = {
  depth0: {
    depth1: {
      attr1: "keep this attribute",
      attr2: { value: "remove me" },
      attr3: "remove me as well"
    }
  },
  someOtherAttribute: "I should be removed"
};

const omitted = omit(
  originalObject,
  "depth0.depth1.attr2",
  "depth0.depth1.attr3",
  "someOtherAttribute"
);

console.log(omitted);
/*
{
  depth0: {
    depth1: {
      attr1: "keep this attribute"
    }
  }
}
*/

omit attribute or nested attribute in every row of array

const originalObject = {
  history: [
    { timestamp: "1234567", value: "example1" },
    { timestamp: "1234568", value: "example1", extraValue: true },
    { timestamp: "1234569", value: "example1" },
    { timestamp: "1234570", value: "example1" }
  ]
};

const omitted = omit(originalObject, "history.value");

console.log(omitted);
/*
{
  history: [
    { timestamp: "1234567" },
    { timestamp: "1234568" },
    { timestamp: "1234569" },
    { timestamp: "1234570" }
  ]
}
*/

omit attribute or nested attribute in specific row of array

const originalObject = {
  history: [
    { timestamp: "1234567", value: "example1" },
    { timestamp: "1234568", value: "example1" },
    { timestamp: "1234569", value: "example1" },
    { timestamp: "1234570", value: "example1" }
  ]
};

const omitted = omit(originalObject, "history.2.value");

console.log(omitted);
/*
{
  history: [
    { timestamp: "1234567", value: "example1" },
    { timestamp: "1234568", value: "example1" },
    { timestamp: "1234569" },
    { timestamp: "1234570", value: "example1" }
  ]
};
*/

clone(originalObject)

const originalObject = {
  depth0: { depth1: { depth2: { value: "nested value" } } }
};
const copiedObject = clone(originalObject);

copiedObject.depth0.depth1.depth2.value = "changed nested value";

console.log(originalObject.depth0.depth1.depth2.value); // outputs "nested value"
console.log(copiedObject.depth0.depth1.depth2.value); // outputs "changed nested value"
