let app  =  new Agent()
    .get("/test/test2", (req,res)=>res.send("working"));

Parametric route

let router = new Agent()
    .get("/test/:userId/:userName", (req,res)=>res.send("working"));

Wildcard route

let router = new Agent()
    .get("/*", (req,res)=>res.send("working"));

Regex route

same syntax as path-to-regexp

let app = new Agent()
    .get("/test/:file(^\\d+).png", (req,res)=>res.send("working"));

get(path: string, ...handler: any[]): Agent

register new Route handler using Http.Get Method

Middlewares

the agent supports any express middleware or cusotom middalwares

import favicon = require('static-favicon');
import bodyParser = require("body-parser");
import {IRequest,IResponse,NextFn}  from 'appolo-agent';

let agent = new Agent()
    .use(bodyParser.json());
    .use(function (req:IRequest, res: IResponse, next: NextFn) {
        res.setHeader("Access-Control-Allow-Origin", "*");
        next();
    })
    .use(favicon());}
    .get("/test/:param", someMiddleware(),(req,res)=>res.send("working"));

IRequest

req.app

instance of the agent

req.get(name:string)

req.header(name:string)

Returns the specified HTTP request header

req.get('content-type'); // => "text/plain"

req.is(type:string)

Returns the matching content type if the incoming request’s “Content-Type” HTTP header field matches the MIME type specified by the type parameter. If the request has no body, returns null. Returns false otherwise.

req.is('html');       // => 'html'
req.is('text/html');  // => 'text/html'

IResponse

the response object inherits from http.ServerResponse

res.status(code: number): IResponse

set response status code

res.status(200).json({name:"value"});

res.contentType(type: string): IResponse

set response content type

res.header(key: string, value: string): IResponse

res.set(key: string, value: string): IResponse

set response header

`res.cache(seconds: number): IResponse

set Cache-Control header in seconds

res.gzip(): IResponse

compress the response with gzip and set Content-Encoding header to gzip

res.redirect(path: string): void

redirect the request to new path

res.cookie(key: string, value: any, options?: cookie.CookieSerializeOptions): IResponse

sets cookie name to value. The value parameter may be a string or object converted to JSON.

res.cookie('name', 'test', { domain: '.example.com', path: '/admin', secure: true });
res.cookie('someName', '{someVal:1}', { expires: new Date(Date.now() + 900000), httpOnly: true });

res.clearCookie(key: string, options?: cookie.CookieSerializeOptions): IResponse

clears the cookie specified by name.

res.cookie('name', 'tobi', { path: '/admin' });
