如何在 JavaScript 中将 JSON 转换为 YAML

2022-01-14 00:00:00 json yaml javascript

我想在 javascript 中将 json 字符串转换为 yaml 格式.我从过去两天开始尝试使用 google，但没有找到任何解决方案或库.有适用于 java 的答案，但不适用于 javascript.

I want to convert a json string to yaml format in javascript.I am trying my hand on google from last two days didnt found any solution or libraries. There are answers available for java but not for javascript.

假设我有这样的 json 字符串:

Suppose i have json string like this:

{
  "json": [
    "fat and rigid"
  ],
  "yaml": [
    "skinny and flexible"
  ],
  "object": {
    "array": [
      {
        "null_value": null
      },
      {
        "boolean": true
      },
      {
        "integer": 1
      }
    ]
  }
}

转换为 yaml:

json:
  - fat and rigid
yaml:
  - skinny and flexible
object:
  array:
    - null_value:
    - boolean: true
    - integer: 1

有一个在线转换器 http://www.json2yaml.com/ ，但是如何转换为它在 javascript 中.

There is a online converter http://www.json2yaml.com/ , but how to convert to it in javascript.

推荐答案

可以使用yaml NPM包.

const YAML = require('yaml');

const jsonObject = {
    version: "1.0.0",
    dependencies: {
        yaml: "^1.10.0"
    },
    package: {
        exclude: [ ".idea/**", ".gitignore" ]
    }
}

const doc = new YAML.Document();
doc.contents = jsonObject;

console.log(doc.toString());

输出

version: 1.0.0
dependencies:
  yaml: ^1.10.0
package:
  exclude:
    - .idea/**
    - .gitignore
