At the moment this repository is not integrated into the npm-modules. In order to use it like one add following to your package.json - file:

"dependencies": {

        "koa-stream-to-file": "https://github.com/unicorn-it/koa-stream-to-file/archive/0.0.1.tar.gz",
        ...

var stf = require('koa-stream-to-file');

try {
    yield stf.saveToFile(this.req, "location/to/save/your/file" + "filename.jpg"); //or other file-type f.e. .png
    } catch (err) {
