Я нашел решение для этого. Спасибо всем, кто пытался мне помочь.
Это мое соединение с БД (дБ. js)
var mysql = require('mysql');
//connect to db
var dbCon = mysql.createPool({
connectionLimit : 50,
host: 'xxxxx',
user: 'xxx',
password: 'xxx',
database: 'xxxxx',
waitForConnections: true,
queueLimit: 0,
});
dbCon.on('connection', function (connection) {
console.log('db pool connection');
connection.query("SET time_zone='+5:30'");
});
dbCon.on('release', function (connection) {
console.log('Connection %d released', connection.threadId);
});
module.exports = {
dbCon
};
Это мое решение.
var express = require('express');
var app = express();
var dbCon = require('./config/db').dbCon;
var fs = require('fs');
var readline = require('readline');
var stream = require('stream');
var data = '';
// Create a readable stream
var readerStream = fs.createReadStream('./data/myJson.jsonl');
// Set the encoding to be utf8.
readerStream.setEncoding('UTF8');
var outstream = new stream();
//createInterface - read through the stream line by line and print out data from it
var r1 = readline.createInterface(readerStream, outstream);
var lineCount = 0;
r1.on('line', function (line) {
// increment line count
lineCount++;
data = JSON.parse(line);
saveRecord(data);
})
function saveRecord(data) {
if (typeof data["city "] !== 'undefined') {
var cityTemp = data["city"];
} else {
cityTemp = "";
}
var property_id = data["property_id"];
var name = data["name"];
var city = cityTemp;
var sql = "INSERT INTO hotels (property_id, name, city) VALUES (?, ?, ?)";
dbCon.query(sql, [property_id, name, city]);
console.log('data inserted');
}
console.log("Program Ended");
