stream support

[sarkistlt]

Need support for NodeJS streams in tinify-nodejs.

The GitHub issue requests an option to stream data instead of loading the whole file into memory, for example when piping from an API to object storage.

Idea: Contact Jovan to see if he wants to work on this as freelancer

There are no update plans for the clients right now but I'm happy to note your request and share the idea with the development team.

I've just tested it with node.js (6.15.1), and you should be able to use the default streams functionality:

import request from 'request';

const r = request.post('https://api:your_key@api.tinify.com/shrink', (err, resp, body) => {
    const obj = JSON.parse(body);

    request.get(obj.output.url); // <== your compressed file url, also pipeable
});

stream.pipe(r);

@HydraOrc hm, didn't thought about directly using API url, looks good, will try, thanks!
But I think you need pipe request.get stream, instead of r, if you want to stream compressed file to write stream distention.

@sarkistlt I mean that at first you should pipe your stream to the post request (r in the case above) to send your data to the tinify api server.
And after that in a callback you could also pipe the request.get(obj.output.url) to write the compressed result to any destination you want to.
In my case it is writing a file to a GridFS storage and it works perfectly, but it could be something else.

For example:
request.get(obj.output.url).pipe(fs.createWriteStream('filename.txt'));
