const cookieParser = require("cookie-parser");
app.use(cookieParser()); // cookies now on req.cookies
Full Example
const http = require("http");
const rm = require("router-middleware");
const app = rm();
const server = http.createServer(app);
app.post("/user/:userId/email", router.bodyParser, function (req, res, next) {
console.log("Query:", req.query);
// { authToken: '1234' }
console.log("Params:", req.params);
// { userId: 'abc123' }
console.log("Body:", req.body);
return res.end(`user id was: ${req.params.userId}\n`);
});
server.listen(5150);
> curl -X POST -d '{"message" : "Hello World!"}' "http://localhost:5150/user/abc123/email?authToken=1234"
Features
- Chainable middleware
- familiar req.params and req.query are there
- identical routing to what you are used to
Any Fileserver
- Ecstatic
- express.static
- fs
How to handle POST (this autodetects json or form querystring)
var http = require("http");
var router = require("router-middleware");
var app = router();
var server = http.createServer(app);
app.post("/user/email", function (req, res, next) {
// Now req.body will be populated with the body posted.
// req.body.username == 'Manny';
// req.body.species == 'cat';
});
server.listen(5150);
How to do a simple GET Fall-Through
var http = require("http");
var router = require("router-middleware");
var ecstatic = require("ecstatic")({ root: __dirname });
var app = router();
app.fileserver(ecstatic);
var server = http.createServer(app);
app.get("/admin", function (req, res, next) {
if (some_condition) {
next(); // will now pass through to the fileserver
// i.e. /admin/index.html or /admin.html
} else {
res.writeHead(403);
res.write("Denied, sorry");
res.end();
}
});
server.listen(5150);
Example
var http = require("http");
var router = require("router-middleware");
var app = router();
var server = http.createServer(app);
app.get("/user/:username", function (req, res, next) {
res.writeHead(200);
res.end("Hello " + req.params.username + "!");
});
server.listen(5150);
// GET /user/joe
// Hello joe!
With Fileserver Ecstatic
var http = require("http");
var router = require("router-middleware");
var app = router();
var ecstatic = require("ecstatic")({ root: __dirname });
var server = http.createServer(app);
app.fileserver(ecstatic);
// any custom routes you set will have precedence
// all other GET requests falls-through to the fileserver
With Fileserver Express
var http = require("http");
var router = require("router-middleware");
var app = router();
var express = require("express");
var server = http.createServer(app);
app.fileserver(express.static("mydirectory"));
// any custom routes you set will have precedence
// all other GET requests falls-through to the fileserver
Main Methods
.[method] (get, post, ... etc)
Attach a handler to any HTTP Method from the full method verb list Handler has the signature function(req, res, next).
.get
app.get("/user/email", function (req, res, next) {
res.write("[email protected]");
res.end();
});
.post
This module comes with a POST body consumer that places the POST body on the req.body
for you.
// suppose we send JSON payload via POST
// { username: 'Manny', species: 'cat' }
app.post("/user/email", function (req, res, next) {
// req.body will be the JSON parsed object that is sent on the post
// req.body.username == 'Manny';
// req.body.species == 'cat';
});
.use
Add a use handler that is placed in front of every call.
app.use(logger);
app.use(parser);
.fileserver(yourFileServer)
Attach any fileserver. Any custom routes you set will have precedence. All other unmatched GET requests falls-through to the fileserver.
Example
app.fileserver(require("ecstatic")({ root: __dirname + "/web" }));
Accessory methods
.set
app.set("<key>", "<value>"); // specify the views directory
