Adapter for express route handlers

Simplify express route handlers.
Aggregate request params into single object (params, body, query).
Takes care of response sending.
Works with promises.
You only need to return value from route handler.

Installation

npm install express-json-res

Usage

var app = require('express')();
var adapt = require('express-json-res');
var bodyParser = require('body-parser');
var Q = require('q'); // or bluebird
 
app.use(bodyParser());
 
// Response body will be json array -> [1, 2, 3]
app.get('/numbers', adapt(function(params, req) {
    return [1,2,3];
}));
 
// Same with promise -> [1, 2, 3]
app.get('/numbers', adapt(function(params, req) {
    return Q([1,2,3]);
}));
 
// Use params
// GET /numbers?pivot=2 -> [3]
app.get('/numbers', adapt(function(params, req) {
    return [1, 2, 3].filter(function(n) {
        return n > params.pivot;
    });
}));
 
// POST /login
// Request body:
// username: johny
// password: qwerty
app.post('/login', adapt(function(params, req) {
    return someAsyncAuthChecker(params.username, params.password).then(function() {
        return { success: true };
    });
}));
 
// And so on..
