How to perform Insert statement by decoding Base64 in express - node.js

Question

How to decode the param values received which were received as Base64 encoded form and insert into database ?
This is what i have tried.
According to this i am getting one value recieved from the client as
param value and inserting into server ( I have recieved the request
at POST )
No base64 encoding is done here
I am using this code at present :
var express = require('express')
, async = require('async')
, http = require('http')
, mysql = require('mysql');
var app = express();
var connection = mysql.createConnection({
host: 'localhost',
user: '******',
password: "******",
database: 'posting_information_DB'
});
connection.connect();
// all environments
app.set('port', process.env.PORT || 1234);
app.use(express.static(__dirname + '/public/images'));
app.post('/Name/',function(request,response,next){
app.use(express.bodyParser());
var keyName=request.query.Key;
var name_of_restaurants;
async.series( [
function(callback) {
connection.query('INSERT INTO details (name) VALUES (?)', [keyName], function (err, rows, fields)
{
console.log('Connection result error ' + err);
callback();
});
}
// Send the response
] );
} );
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
What i am trying to do !
Now what changes should i need to make so that when i need recieve a
image and string as two param values
These values are Base64 encoded
How to decode these Base64 here and then insert the retrieved param
values to database
How to modify my posted Express code !
Thanks !

You can retrieve the image parameter using request.params and then create a Buffer object, specify the base64 encoding and then convert it using the .toString() method.
app.post('/Name/', function(request, response, next){
var image = new Buffer(request.params.image, 'base64').toString('binary');
// do the database insert...
});
