Node.js base64 encode a downloaded image for use in data URI

Question

Using Node v0.2.0 I am trying to fetch an image from a server, convert it into a base64 string and then embed it on the page in an image tag. I have the following code:

Answer 1

This works for me using request:

const url = 'http://host/image.png';
request.get({url : url, encoding: null}, (err, res, body) => {
    if (!err) {
        const type = res.headers["content-type"];
        const prefix = "data:" + type + ";base64,";
        const base64 = body.toString('base64');
        const dataUri = prefix + base64;
    }
});

No need for any intermediate buffers. The key is to set encoding to null.
