Object 를 string, yaml, buffer 로 변환하기

Object <-> String

const obj = {
    id: 'stove99',
    rel: {
        friends: ['hd', 'er']
    }
};

// object <-> string
const json_str = JSON.stringify(obj);

console.log(json_str); // {"id":"stove99","rel":{"friends":["hd","er"]}}

console.log(JSON.parse(json_str)); // { id: 'stove99', rel: { friends: [ 'hd', 'er' ] } }

Object <-> Buffer

npm i bson

# 또는
yarn add bson

import * as bson from 'bson';

const obj = {
    id: 'stove99',
    rel: {
        friends: ['hd', 'er']
    }
};

const buf = bson.serialize(obj);

console.log(buf); // <Buffer 41 00 00 00 02 69 64 00 08 ....>

console.log(bson.deserialize(buf)); // { id: 'stove99', rel: { friends: [ 'hd', 'er' ] } }

Object <-> yaml

npm i yaml

# 또는
yarn add yaml

import * as yaml from 'yaml';

const obj = {
    id: 'stove99',
    rel: {
        friends: ['hd', 'er']
    }
};

const yaml_str = yaml.stringify(obj);

/*
id: stove99
rel:
  friends:
    - hd
    - er
*/
console.log(yaml_str);

console.log(yaml.parse(yaml_str)); // { id: 'stove99', rel: { friends: [ 'hd', 'er' ] } }
