function

YAML.stringify

input: unknown,

replacer?: null,

space?: string | number

): string;

Convert a JavaScript value into a YAML string. Strings are double quoted if they contain keywords, non-printable or escaped characters, or if a YAML parser would parse them as numbers. Anchors and aliases are inferred from objects, allowing cycles.

@param input

The JavaScript value to stringify.

@param replacer

Currently not supported.

@param space

A number for how many spaces each level of indentation gets, or a string used as indentation. Without this parameter, outputs flow-style (single-line) YAML. With this parameter, outputs block-style (multi-line) YAML. The number is clamped between 0 and 10, and the first 10 characters of the string are used.

@returns

A string containing the YAML document.

import { YAML } from "bun";

const input = {
  abc: "def",
  num: 123
};

// Without space - flow style (single-line)
console.log(YAML.stringify(input));
// {abc: def,num: 123}

// With space - block style (multi-line)
console.log(YAML.stringify(input, null, 2));
// abc: def
// num: 123

const cycle = {};
cycle.obj = cycle;
console.log(YAML.stringify(cycle, null, 2));
// &1
// obj: *1
