Image proxy and base64 string generator.
Requests are proxied to http://dummyimage.com by default.
Used by dyson-generators (for base64 image strings) and dyson (as middleware).
Install dyson-image locally by including it in package.json as a devDependency:
"devDependencies": {
"dyson-image": "~0.1"
}
The image.request() method returns a promise which gets resolved with an object containing mimeType and buffer.
The examples below both create a base64 string representation of a 300x200 image:
var image = require('dyson-image');
image.request({
host: 'http://dummyimage.com',
path: '/300x200'
}).then(function(imageObj) {
var imgBase64 = imageObj.buffer.toString('base64');
console.log('data:' + imageObj.mimeType + ';base64,' + imgBase64);
});
image.request({
width: 300,
height: 200
}).then(function(imageObj) {
//
});
var image = require('dyson-image');
app.get('/image/*', image.asMiddleware);
A request to /image/300x200 will be proxied to http://dummyimage.com/300x200, and served as image.
