## flask-router Routing system for node.js/connect based on Flask(http://flask.pocoo.org/). #### Installation ```sh npm install flask-router ``` #### Usage ```js var http = require('http') , router = require('flask-router')() , server = http.createServer(router.route); ``` It can also be used as a connect/express middleware: ```js var connect = require('connect') , app = connect() , router = require('flask-router')() , app.use(router.route); ``` Then routes can be added like this: ```js router.get('/users/', function (req, res) { console.log(req.params.id); res.end(); }); router.post('/users/', function (req, res) { console.log(req.params.id); res.end(); }); router.put('/customers/', function (req, res) { console.log(req.params.id); res.end(); }); ``` Can assign multiple handler functions to the same rule: ```js router.get('/get/' , function(req, res, next) { res.write('part1'); next(); }, function(req, res, next) { res.write('part2'); next(); }); router.get('/get/', function(req, res) { res.write('part3'); res.end(); }); // All three handlers will be executed when the url match, so the final // response will be 'part1part2part3' ``` Custom parameter parsers can be registered(these are known as 'converters' in Flask/Werkzeug): ```js router.registerParser('query', function(str) { var rv = {}; , queryParams = str.split('/') , i, len, kv, key, value; for (i = 0, len = queryParams.length; i < len; i++) { param = queryParams[i]; kv = param.split('='); key = kv[0], value = kv[1]; rv[key] = value; } return rv; }); router.get('/queryable/', function(req, res) { console.log(JSON.stringify(req.params.q)); res.end(); }); // If '/queryable/gt=5/lt=10/limit=20' was requested, // the output would be {"limit":"20","gt":"5","lt":"10"} ``` Can be used to write middlewares, just like express routes: ```js // anyone can access public files router.get('/public/', function(req, res) { res.write(req.params.file); res.end(); }); // will match any path that starts with /private router.all('/private/', function(req, res, next) { if (req.headers['x-user']) { req.loggedIn = true; next('route'); } else { next(); } }); router.all('/private/', function(req, res) { res.writeHead(401); // not authorized res.end(); }); // the next two handlers will only be executed if the user is // authorized(in this case, the request must have x-user header) router.post('/private/addpost/', function(req, res) { // req.loggedIn === true res.write('post added')); res.end(); }); router.get('/private/posts', function(req, res) { // req.loggedIn === true res.write(db.query('posts')'); res.end(); }); ``` RegExps can also be used as rules: ```js router.get(/^\/posts\/(\d+)/i, function(req, res) { // Will match /posts/5 or /POSTs/32422 // captured text can be accessed by index on req.params console.log('Id:', req.params[0]) res.end() }) ``` See tests for more examples. </article></body></html>
