Querying MySQL with Node.JS and display results in webpage
Easiest way would be to use a node framework. Like express.
You will be doing something like
/*** omitting generic code for clarity ***/
app.get('/yourpage',function(req,res){
//On request of this page initiating sql query. Assumes that the object initialization is done above.
mySqlClient.query(
selectQuery,
function select(error, results, fields) {
if(error) {
console.log(error);
mySqlClient.end();
//render the template with error to be alerted
res.render('tempaltefile',{data:null,error:error});
}
if(results.length > 0) {
//console.log(results);
//render the template with fetched data
res.render('tempaltefile',{data:results,error:null});
} else {
//console.log('No data');
//render the template with empty data alert
res.render('tempaltefile',{data:null,error:"no data"});
}
mySqlClient.end();
});
});

please mention you are using this along side ph code. I think you have to biuld the node code an api and consume it in the php end.

My goal is to query MySQL with Node.JS for better interactivity. My query is a simple
SELECT
withJOIN
s. I managed to construct a script that displays results in the console but I'm kind of stuck when it comes to display it in the webpage. Here is my code:var mysql = require('mysql'); var mySqlClient = mysql.createConnection({ host : 'server', user : 'login', password: 'pwd', database: 'db' }); var selectQuery = 'SELECT fields FROM table t1\ INNER JOIN table t2\ ON t1.field = t2.field'; mySqlClient.query( selectQuery, function select(error, results, fields) { if(error) { console.log(error); mySqlClient.end(); return; } if(results.length > 0) { console.log(results); } else { console.log('No data'); } mySqlClient.end(); });
What is the best approach to include this into the webpage? Do I need to create a httpServer with Node.JS?
Many thanks for any help!
EDIT I would like to use Node.JS inside a PHP application designed with Zend Framework. The Node.JS app wouldn't be the sole app of my project.

D4V1D about 10 yearsThanks for reply, is this compatible with an already existing front end app such as a Zend Framework app? How can I include express.js in ZF?
