Wallet-Draining npm Package Impersonates Nodemailer to Hijack Crypto Transactions
Malicious npm package impersonates Nodemailer and drains wallets by hijacking crypto transactions across multiple blockchains.
Time based event loop process queue
Install the module with: npm install compulsive

Repeat count
times, every ms

Queue tasks.
// list

var compulsive = require("compulsive");
compulsive.wait( 10, function() {
// Will execute in 10ms
// ... doesn't use setTimeout.
});
compulsive.loop( 50, function( control ) {
// Will execute every 50ms
// ... doesn't use setTimeout or setInterval.
// The loop can be stopped via:
control.stop();
});
compulsive.repeat( 5, 100, function( control ) {
// Will execute 5 times, every 100ms
// ... doesn't use setTimeout or setInterval.
// The repeater loop can be stopped via:
control.stop();
});
compulsive.queue([
{
wait: 100,
task: function() {
// 100 from call to execution
}
},
{
wait: 200,
task: function() {
// 100 + 200 = 300ms from call to execution
}
}
]);
Add compulsive api to your constructor's prototype:
var compulsive = require("compulsive"),
priv = new require("es6-collections").WeakMap();
function Nodebot() {
//... various nodebot constructor tasks
this.servos = {
right: new Servo(9),
left: new Servo(10)
};
priv.set( this, {
step: null
});
}
// Exposure grants the end dev control
// over stepping positions (0-180˚)
Nodebot.STEPS = {
// Step: [ R, L ]
right: { right: 120, left: 60 },
left: { right: 60, left: 120 }
};
// Augment the Nodebot prototype
// with compulsive APIs
[ "wait", "loop", "queue" ].forEach(function( api ) {
Nodebot.prototype[ api ] = compulsive[ api ];
});
Nodebot.prototype.step = function() {
var p, next, last, degrees;
p = priv.get(this);
last = p.step;
next = last === "right" ? "left" : "right";
degrees = Nodebot.STEPS[ next ];
Object.keys( this.servos ).forEach(function( servo ) {
servo.move( degrees[ servo ] );
});
};
Nodebot.prototype.walk = function() {
this.loop( 1000, this.step.bind(this) );
};
module.exports = Nodebot;
var Nodebot = require("nodebot"), ,
bot = new Nodebot();
bot.walk();
