How to properly serve a dinamic image with Node and Express?

Question

I'm having many problems to achive what I'm trying:

I want to request an image from this URL http://tapas.clarin.com/tapa/1990/02/22/19900222_thumb.jpg and show it in the view but I'm getting this showned in the view instead:

What's the proper way of achieving what I want ?

This is my code:

const app = require('express')(); var http = require('http').Server(app); var rp = require('request-promise'); const fs = require('fs') var url = 'http://tapas.clarin.com/tapa/1990/02/22/19900222_thumb.jpg' app.get('/', (req, res) => { rp(url) .then(image => res.set('Content-Type', 'image/jpeg').send(image)) .catch(err => res.send(err)); }) http.listen(3000, () => { console.log('listening on localhost:3000'); });

You need to set content type. res.set('Content-Type', 'image/jpeg').send(image) — ponury-kostek

You're getting back a string from request-promise, not a buffer.Setting encoding: null, will get you a buffer which you can send back.

const app = require('express')(); var http = require('http').Server(app); var rp = require('request-promise'); var options = { url: 'http://tapas.clarin.com/tapa/1990/02/22/19900222_thumb.jpg', encoding: null } app.get('/', (req, res) => { rp(options) .then(image => { return res.end(image,'binary'); }) .catch(err => res.send(err)); }) http.listen(3000, () => { console.log('listening on localhost:3000'); });
