Is there something of http gateway?

[zhaoyao91]

Cote is great, but the communications are enclosed in its own system. Other apps of different framework or language are difficult to chat with them.

Is there or planning to build an out-of-box http gateway component to proxy the in-out communications?

Hi! In fact there was a pull request earlier to streamline this — #27. However we weren't satisfied with the API and stopped working on it. I'd love to help more contributors on this.

I think that out of the box API gateway is not needed. It's based on application.

For example, my app doesn't not use API Gateway, I am using cote for my many-platforms chat bot.

I'm with @mikield on this.

I don't know how much value an out-of-the-box http gateway would add. You'd likely want some sort of auth/middleware in the mix or ability to customize the end points, perform validation, etc.

Users are better off taking their favorite REST framework and building a wrapper around a Requester.

That’s right. That’s also partially why we didn’t merge this. However, cote could still provide an easier interface for —for example— Express apps to hook into. Currently it requires a lot of boilerplate that gets repetitive and error prone.

How much simpler could you get than this?

app.get('/product', function(req, res) {
    productRequester.send({type: 'list'}, function(err, products) {
        res.send(products);
    });
});

Perhaps I could see cote returning a handler that accepts req/res to narrow it down to a single line:

app.get('/product', productRequester.httpHandler({type: 'list'}));

But... there are many different frameworks out there. Most of them have express-compatibility so perhaps this may be enough, but could be limiting if you use a library that breaks away from that norm.

This is route/event based match up. There are multiple other ways possible, including having a single URL and then forwarding to different events based on POST parameters, or configuration when you instantiate a responder:

const responder = new cote.Responder({
  name: 'Products responder', 
  http: {
    server: existingExpressApp, 
    path: '/products/:type'
  }
})

As I already mentioned - I think that should be created as a separated wrapper. Cote is not a Http framework, am I right? @dashersw

Thats why I love to use it. It's not forcing me to follow Http Microframework style, but just to use simple tcp messaging.

Of course I can be wrong.

[dashersw]

You don't have to use any http microframework style — this would just be an addition to how cote operates on its own. A separate wrapper or a plugin can still provide this functionality.
