I have a logo that is residing at the public/images/logo.gif
. Here is my nodejs code.
http.createServer(function(req, res){
res.writeHead(200,
It is too late but helps someone, I'm using node version v7.9.0
and express version 4.15.0
if your directory structure is something like this:
your-project
uploads
package.json
server.js
server.js code:
var express = require('express');
var app = express();
app.use(express.static(__dirname + '/uploads'));// you can access image
//using this url: http://localhost:7000/abc.jpg
//make sure `abc.jpg` is present in `uploads` dir.
//Or you can change the directory for hiding real directory name:
`app.use('/images', express.static(__dirname+'/uploads/'));// you can access image using this url: http://localhost:7000/images/abc.jpg
app.listen(7000);
//This method involves directly integrating HTML Code in the res.write
//first time posting to stack ...pls be kind
const express = require('express');
const app = express();
const https = require('https');
app.get("/",function(res,res){
res.write("<img src="+image url / src +">");
res.send();
});
app.listen(3000, function(req, res) {
console.log("the server is onnnn");
});
var http = require('http');
var fs = require('fs');
http.createServer(function(req, res) {
res.writeHead(200,{'content-type':'image/jpg'});
fs.createReadStream('./image/demo.jpg').pipe(res);
}).listen(3000);
console.log('server running at 3000');
I like using Restify for REST services. In my case, I had created a REST service to serve up images and then if an image source returned 404/403, I wanted to return an alternative image. Here's what I came up with combining some of the stuff here:
function processRequest(req, res, next, url) {
var httpOptions = {
hostname: host,
path: url,
port: port,
method: 'GET'
};
var reqGet = http.request(httpOptions, function (response) {
var statusCode = response.statusCode;
// Many images come back as 404/403 so check explicitly
if (statusCode === 404 || statusCode === 403) {
// Send default image if error
var file = 'img/user.png';
fs.stat(file, function (err, stat) {
var img = fs.readFileSync(file);
res.contentType = 'image/png';
res.contentLength = stat.size;
res.end(img, 'binary');
});
} else {
var idx = 0;
var len = parseInt(response.header("Content-Length"));
var body = new Buffer(len);
response.setEncoding('binary');
response.on('data', function (chunk) {
body.write(chunk, idx, "binary");
idx += chunk.length;
});
response.on('end', function () {
res.contentType = 'image/jpg';
res.send(body);
});
}
});
reqGet.on('error', function (e) {
// Send default image if error
var file = 'img/user.png';
fs.stat(file, function (err, stat) {
var img = fs.readFileSync(file);
res.contentType = 'image/png';
res.contentLength = stat.size;
res.end(img, 'binary');
});
});
reqGet.end();
return next();
}
This method works for me, it's not dynamic but straight to the point:
const fs = require('fs');
const express = require('express');
const app = express();
app.get( '/logo.gif', function( req, res ) {
fs.readFile( 'logo.gif', function( err, data ) {
if ( err ) {
console.log( err );
return;
}
res.write( data );
return res.end();
});
});
app.listen( 80 );
