Answer 1

If CORS in the problem you could use the node module cors
Here is a example on how to configure cors with express!

Answer 2

replace the above code with below to allow cross-request the
var express = require('express');
var mysql = require('mysql');
var app = express();
app.use(bodyparser.urlencoded({extended: true}));
app.use(bodyparser.json({ limit: '50mb' }));
app.use(function (req, res, next) {
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'POST, GET, PUT, DELETE, OPTIONS');
res.setHeader('Access-Control-Allow-Headers', 'access-control-allow-methods,access-control-allow-origin,x-access-token,content-type,Origin, X-Requested-With, Accept');
res.setHeader('Access-Control-Allow-Credentials', true);
next();
});
var connection = mysql.createConnection({
// connectionLimit : 100, //important
host : 'localhost',
user : 'root',
password : 'root',
database : 'socialwiki'
});
connection.connect(function(error){
if(!!error){
console.log('error');
}else{
console.log('connected');
}
});
exports.getlist = function( req, res ) {
console.log(req.id);
connection.query("SELECT * FROM profile",function(error,result,rows,fields){
if(!!error){
console.log('fail');
}else{
console.log(result);
res.send(result);
}
});
};
