javascript - 从数组动态创建Json文件

Question

我想从数组创建多个 JSON 文件。

数组:

 [{
    "Reference": "Registration",
    "langkey": "REG_LBL",
    "English": "Company Registration",
    "Japanese": "会社登録"
}, {
    "Reference": "Registration",
    "langkey": "INFO_LBL",
    "English": "Company Information",
    "Japanese": "会社情報"
}]

我需要从上面的数组创建两个名为英语和日语的 JSON 文件(它将是动态的)。

所需输出

English.json

{
'INFO_LBL' : 'Company Information',
'REG_LBL':'Company Registration'
}

日语.json

{
'INFO_LBL' : '会社情報',
'REG_LBL':'会社情報'
}

代码

for (var i = 0; i < data.length; i++) {
    var obj = data[i];
    for (var key in obj) {
        if (key !=='Reference' && key !== 'langkey' ) {
            //{'REG_LBL':'Company Registration'}

            objects[obj['langkey']] = obj[key];
            fs.writeFileSync('lang/' + langkey + '.json', JSON.stringify(objects, null, 2), { encoding: 'utf8' }, function (err) {
                if (err)
                { throw err; }
                console.log("completed")

            });

        }
    }
}

我可以创建两个 JSON 文件，但内容被另一个文件覆盖。请帮助解决此问题？

Answer 1

var finalObject = {};//create new object

data.forEach(v => {
    var langkey = v.langkey;
    Object.keys(v).forEach(val => {
        if (val != 'langkey' && val != 'Reference') {
            if (finalObject[val]) {//find if language object is already created.If already created insert in it else create new
                let data = {};
                data[langkey] = v[val]
                finalObject[val] = Object.assign(finalObject[val], data)
            } else {
                finalObject[val] = {};
                finalObject[val][langkey] = v[val];
            }


        }
    })
})
Object.keys(finalObject).forEach(key => {
    fs.writeFileSync(path.join(__dirname, `/lang/${key}.json`), JSON.stringify(finalObject[key], null, 2), (err) => {
        if (err)
        { throw err; }
        console.log('completed');
    });
})
