deepest-walk

The Deepest JSON Object Walking Library

Traverse and Modify Arrays, Objects, Numbers, Strings, and Substrings.

why is it the deepest?

There are many great object walking libraries. However, I'm not aware of any other library that will traverse substrings within the strings found in a JSON Object.

install

npm install deepest-walk

types

• array
• object
• array-item-string
• array-item-substring
• object-key-string
• object-key-substring
• object-value-string
• object-value-substring
• undefined
• null
• number

usage

basic usage

const walk = require("deepest-walk");

const data = [
  { name: 'George Washington' },
  { name: 'John Adams' }
];
const callback = ({ data }) => console.log(data);
walk({ data, callback, types: ["object-value-string"] });

This will log:

George Washington
John Adams

breaking on words

Set split_strings_on to " " to break on words

const walk = require("deepest-walk");

const data = [
  { name: 'George Washington' },
  { name: 'John Adams' }
];
const callback = ({ data }) => console.log(data);
walk({ data, callback, types: ["object-value-substring"], split_strings_on: " " });

This will log:

George
Washington
John
Adams

modifying words

The following capitalizes all the strings

const walk = require("deepest-walk");

const data = [
  { name: 'George Washington' },
  { name: 'John Adams' }
];
const callback = ({ data, mod, type }) => {
  if (typeof data === "string") {
    mod(data.toUpperCase());
  }
};

walk({ data, callback });

Data will be:

[
  { NAME: 'GEORGE WASHINGTON' },
  { NAME: 'JOHN ADAMS' }
];
