How would one do a bulk insert into mySQL if using something like https://github.com/felixge/node-mysql

Answer 1

In case that needed here is how we solved insert of array

request is from postman (You will look at "guests" )

 {
  "author_id" : 3,
  "name" : "World War II",
  "date" : "01 09 1939", 
  "time" : "16 : 22",
  "location" : "39.9333635/32.8597419",
  "guests" : [2, 3, 1337, 1942, 1453]
}

And how we scripted

var express = require('express');
var utils = require('./custom_utils.js');

module.exports = function(database){
    var router = express.Router();

    router.post('/', function(req, res, next) {
        database.query('INSERT INTO activity (author_id, name, date, time, location) VALUES (?, ?, ?, ?, ?) ON DUPLICATE KEY UPDATE name = VALUES(name), date = VALUES(date), time = VALUES(time), location = VALUES(location)', 
                [req.body.author_id, req.body.name, req.body.date, req.body.time, req.body.location], function(err, results, fields){
            if(err){
                console.log(err);
                res.json({ status: utils.respondMSG.DB_ERROR });
            }
            else {
                var act_id = results.insertId;
                database.query('INSERT INTO act_guest (user_id, activity_id, status) VALUES ? ON DUPLICATE KEY UPDATE status = VALUES(status)', 
                        [Array.from(req.body.guests).map(function(g){ return [g, act_id, 0]; })], function(err, results, fields){
                    if(err){
                        console.log(err);
                        res.json({ status: utils.respondMSG.DB_ERROR });
                    }
                    else {
                        res.json({ 
                            status: utils.respondMSG.SUCCEED,
                            data: {
                                activity_id : act_id
                            }
                        });
                    }
                });
            }
        });
    });
    return router;
};
