Add more types in response.send

[jesusvilla]

Hi all. response.send should support the following variable types:

• [x] String
• [x] Object
• [x] Error
• [x] Buffer (with default header)
• [x] Stream
• [x] Promise

[jkyberneees]

Hi @jesusvilla, I agree with your suggestion. We should extend the current implementation and support those suggested types.

Would you like to contribute on this with a PR?

Regards

Hi @jkyberneees Yeah, give me a few hours please.

@jkyberneees for the Buffer types I have an observation:

• The header must be set by default: Content-Type 'application/octet-stream'
• If you want it to return as text, you must indicate the header: Content-Type 'text/plain; charset=utf-8 '

Before:

service.get('/hello', (req, res) => {
  res.send(Buffer.from('Hello World!'))
})

Now:

service.get('/hello', (req, res) => {
  res.setHeader('content-type', 'text/plain')
  res.send(Buffer.from('Hello World!'))
})

Hi @jesusvilla, I have reviewed and applied some minor changes to your PR on the extend-send-method branch. The major reason was performance improvements. New PR: https://github.com/jkyberneees/ana/pull/90

I kindly ask you to have a look, I would assume you also want to implement Promise support? Just let me know.

NOTE: Please consider to avoid performance degradation if you want to support promises.

Regards

Hi @jkyberneees, I forgot to add Promise, sorry. btw, put some remarks on your commits, there are a lot of changes on my original code, I prefer you continue on Promise.

[jkyberneees]

Hi @jesusvilla I understand. Thank you very much for contributing, I will take it from here then.

Regards.

Hi @jesusvilla, as described in https://github.com/jkyberneees/ana/pull/90, I have released the res.send method extensions with several fixes and support for Streams.

Promises are still not supported, I will followup on this in the future.

Regards.

I took a shot at implementing the promises functionality. I don't think it performs too well at the moment, I want to see if I can optimize it in anyway before I make a PR to your master branch.

Current results I am seeing.

This @edreesjalili for supporting us here. With the merge of https://github.com/jkyberneees/ana/pull/93 I proceed to close this issue. Promise support will be available in v4.6.0.

Thank you!
