[英]How I can change structure of multiple arrays to array objects Node.js?
(Variable file contains array of URL .json files). (变量文件包含URL .json文件数组)。 One file in subdirectories contains: 子目录中的一个文件包含:
[ {"name": "John"} ]
Then I get common file get.json who contains all files from subdirectories in structure (yeap, I know it's not a valid JSON): 然后,我得到通用文件get.json,该文件包含结构子目录中的所有文件(是的,我知道这不是有效的JSON):
[ {"name": "John"} ]
[ {"name": "Sergei"} ]
I want get this file in this structure: 我想要此文件的结构如下:
[ {name: "John"}, {name: "Sergei"} ]
My code 我的密码
recursive(`${dirPath}`, ['delete.json', 'put.json'], function (err, file) {
const write = fs.createWriteStream(`${dirPath}/get.json`);
file.forEach(item => {
fs.createReadStream(item).pipe(write);
})
write.on('finish', () => {
fs.createReadStream(`${dirPath}/get.json`).pipe(res);
})
});
One day from my life left with this task, done! 离我生命中的这一天完成了!
recursive(`${dirPath}`, ['delete.json', 'put.json'], function (err, file) {
const write = fs.createWriteStream(`${dirPath}/get.json`);
const usersArr = [];
let readStream;
file.forEach(item => {
readStream = fs.createReadStream(item);
readStream.on("data", (data) => {
JSON.parse(data).map(item => usersArr.push(item));
});
})
readStream.on("end", (data) => {
write.write(JSON.stringify(usersArr, null, " "), () => {
console.log('Completed');
});
fs.createReadStream(`${dirPath}/get.json`).pipe(res)
});
});
const names = data.split('\n')
.map(nameArrayString => (JSON.parse(nameArrayString)[0]))
