Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
express-controllers
Advanced tools
express-controllers adds controller style routing from the model-view-controller paradigm to express using express-resource.
npm:
$ npm install express-controllers
var express = require('express')
var controllers = require('express-controllers')
var app = module.exports = express().controllers();
if (!require.parent) {
var server = app.listen(3000, function() {
var host = server.address().address;
var port = server.address().port;
console.log('Express 4 server listening at http://%s:%s', host, port);
});
}
By default, the app.controllers()
method will load any controllers in the directory named controllers
of your application (wherever server.js/app.js is). If you prefer to store your controllers in a different location, simply specify your desired path in the app setting via app.set('controllers path', '/path/to/controllers/')
.
To get started simply require('express-controllers')
, and this module will monkey-patch Express, enabling the controller style routing by providing the app.controllers()
method.
A "controller" is simply a module which defines one of more of the supported "actions", listed below:
exports.index = function(req, res) {
res.send('forum index');
};
exports.new = function(req, res) {
res.send('new forum');
};
exports.create = function(req, res) {
res.send('create forum');
};
exports.show = function(req, res) {
res.send('show forum ' + req.params.forum);
};
exports.edit = function(req, res) {
res.send('edit forum ' + req.params.forum);
};
exports.update = function(req, res) {
res.send('update forum ' + req.params.forum);
};
exports.destroy = function(req, res) {
res.send('destroy forum ' + req.params.forum);
};
Actions are then mapped as follows (by default), providing req.params.forum
which contains the substring where ":forum" is shown below:
GET /forums -> index
GET /forums/new -> new
POST /forums -> create
GET /forums/:forum -> show
GET /forums/:forum/edit -> edit
PUT /forums/:forum -> update
DELETE /forums/:forum -> destroy
Currently express-controllers (by way of express-resource) supports basic content-negotiation support utilizing extnames or "formats". This can currently be done two ways, first we may define actions as we normally would, and utilize the req.format
property, and respond accordingly. The following would respond to GET /pets.xml
, and GET /pets.json
.
var pets = ['tobi', 'jane', 'loki'];
exports.index = function(req, res) {
switch (req.format) {
case 'json':
res.send(pets);
break;
case 'xml':
res.send('<pets>' + pets.map(function(pet) {
return '<pet>' + pet + '</pet>';
}).join('') + '</pets>');
break;
default:
res.send(406);
}
};
The following is equivalent, however we separate the logic into several callbacks, each representing a format.
exports.index = {
json: function(req, res) {
res.send(pets);
},
xml: function(req, res){
res.send('<pets>' + pets.map(function(pet) {
return '<pet>' + pet + '</pet>';
}).join('') + '</pets>');
}
};
We may also provide a default
format, invoked when either no extension is given, or one that does not match another method is given:
exports.default = function(req, res) {
res.send('Unsupported format "' + req.format + '"', 406);
};
