Prints a JSON structure (or any POJO) to the console. Can print to a single line or to a tree structure.
Install the package using NPM or Yarn:
npm install pojo-dump # or yarn add pojo-dump
The library provides the following exports:
toLine: Formats data into a compact, single-line JSON-like representation.toTree: Formats data into a tree-like structure for better readability.logTree: Logs the tree-like structure to the console.Print to a single line:
import { toLine } from 'pojo-dump';
const data = [null, true, false, 123, 0.1, 'as\ndf', [1, 2, 3], { foo: 'bar' }];
console.log(toLine(data));
// [ !n, !t, !f, 123, .1, "as" ⏎ "df", [ 1, 2, 3 ], { foo = "bar" } ]
Print to a multi-line tree layout:
import { toTree } from 'pojo-dump';
const data = { foo: 'bar', nested: [1, 2, { key: 'value' }] };
console.log(toTree(data));
/*
Output:
╿
├─ foo = "bar"
└─ nested
├─ [0]: 1
├─ [1]: 2
└─ [2]
└─ key = "value"
*/
Constant literals:
console.log(toLine([true, false, null, undefined])); // Output: [ !t, !f, !n, !u ]
Number literals:
console.log(toLine([1000, 0.1])); // Output: [ 1,000, .1 ]
Formatting strings with special characters:
console.log(toLine('hello\nworld'));
// Output: "hello" ⏎ "world"Formatting binary data:
console.log(toLine(new Uint8Array([104, 101, 108, 108, 111])));
// Output: Uint8Array { 68 65 6C 6C 6F }Apache 2.0
