Node Unirest Promise Wrapper

unirest_promise.js

function unirest_prom(unirest_req, always_resolve) {
  // Returns a Promise by wrapping a unirest.Request object in
  // a Promise that immediately calls `.end(...)`
  //
  // Params:
  //
  // *   unirest_req - unirest.Request - any unirest Request object that has
  //                   not yet had `.end(...)` called on it
  // *   always_resolve - bool (optional) - defaults to `false`, iff `true` then
  //                      the Promise always resolves--even when the request fails
  //                      (since HTTP errors are encapsulated in the `response`
  //                      object). A unirest.Response object is passed to either
  //                      `resolve` or `reject`.
  //
  return new Promise((resolve, reject) => {
    unirest_req.end(r => {
      return ((always_resolve === true ||
               (r.status >= 200 && r.status < 300)) ?
              resolve(r) :
              reject(r));
    });
  });
}

As of September 2017 the unirest Node package doesn’t support promises. Here’s a simple way to wrap a unirest.Request object and turn it into a Promise instead of calling .end(…). I went ahead and had non-200 responses get rejected, unless you set always_resolve === true.

Hi @mrcoles, where is always_resolved coming from thanks

is this still working? as I tried to call it and then subsequently
const data = function unirest_prom()
console.log(await data)

i.e data is not available outside the context of the function? so if something happens like making a server call and getting back 200 statusCode, does that still make this visible outside of the call?
