yijson（易 JSON，json 压缩和解压工具）
参考方案
注意：jsonCrush 的压缩效果更好，压缩速度更慢
jsonCrush 压缩
import { jsonCrush } from '@yicode/yijson';
let json = {
type: 'world',
name: 'earth',
children: [
{
type: 'continent',
name: 'America',
children: [
{
type: 'country',
name: 'Chile',
children: [
{
type: 'commune',
name: 'Antofagasta'
}
]
}
]
},
{
type: 'continent',
name: 'Europe'
}
]
};
let packed = jsonCrush(json);
console.log(packed);
// 打印:

import { jsonUncrush } from '@yicode/yijson';
let text = '.world-earth*0America*untry-Chile*mmune-Antofagasta'11),.co0Europe'1)*'~children![.co-'~name!'.('type!'0ntinent-1)]10.-*_';
let unpacked = jsonUncrush(text);
console.log(unpacked);
