Answer 1

If someone still wants to convert JSON to YAML, you may use this JavaScript library: https://www.npmjs.com/package/json2yaml

Answer 2

I tried to package the answer to a bash script.

#!/bin/bash
#convert-json-to-yaml.sh

if [[ "$1" == "" ]]; then
    echo "You must provide a json file in argument i.e. ./convert-json-to-yaml.sh your_file.json"
    exit 1
fi

jsonFile=$1
yamlFile="$1.yaml"

if [[ "$2" != "" ]]; then
    yamlFile=$2
fi

python -c 'import sys, yaml, json; yaml.safe_dump(json.load(sys.stdin), sys.stdout, default_flow_style=False)' < ${jsonFile} > ${yamlFile}

Answer 3

Use the 'js-yaml' npm package! That's the one that is officially recognized by yaml.org. (If you want to be extra sure && this post is outdated, go check yaml.org yourself to see which package it recommends.) I initially used 'json2yaml' instead and got strange parsing behavior when converting json (as string) to yaml.

You can use yaml NPM package.

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());

Output

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