 - Similarly, `req.body` can either be a string or a readable stream.
 
+- Also, you can handle rejected fetch requests through checking `err.type` and `err.code`.

 - Only support `res.text()` and `res.json()` at the moment, until there are good use-cases for blob.
 
 - There is currently no built-in caching, as server-side caching varies by use-cases.

 Instead of implementing `XMLHttpRequest` in node to run browser-specific [fetch polyfill](https://github.com/github/fetch), why not go from node's `http` to `fetch` API directly? Node has native stream support, browserify build targets (browsers) don't, so underneath they are going to be vastly different anyway.

 - Use native promise, but allow substituting it with [insert your favorite promise library].
 - Use native stream for body, on both request and response.
 - Decode content encoding (gzip/deflate) properly, and convert string output (such as `res.text()` and `res.json()`) to utf-8 automatically.
-- Useful extensions such as timeout, redirect limit, response size limit.
