co-request promisify wrapper for request
Simple wrapper to the request library for co-like interface (node.js generator based code). You can use it with koa or co
To install simply run:
npm install co-request
Require co first, also it will work on node v0.11.7 and newest only.
You must run node with --harmony flag (--harmony-generators as well)
node --harmony simple.js
Simple example:
"use strict";
let co = require("co");
let request = require("co-request");
co(function* () {
// You can also pass options object, see http://github.com/mikeal/request docs
let result = yield request("http://google.com");
let response = result;
let body = result.body;
console.log("Response: ", response);
console.log("Body: ", body);
}).catch(function (err) {
console.err(err);
});
POST example:
"use strict";
co(function* () {
let result = yield request({
uri: "http://google.com",
method: "POST"
});
})();
To pipe request you should use small helper (thanks to greim):
function pipeRequest(readable, requestThunk){
return function(cb){
readable.pipe(requestThunk(cb));
}
}
//..and then:
var value = yield pipeRequest(this.req, request({...}));
All methods of request listed in Request docs
