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.
A lightweight (only 1kb gzipped) scroll animation javascript library without any dependency.
$ npm install moveto --save
$ yarn add moveto
$ bower install moveTo --save
const moveTo = new MoveTo();
const target = document.getElementById('target');
moveTo.move(target);
// Or register a trigger
const trigger = document.getElementsByClassName('js-trigger')[0];
moveTo.registerTrigger(trigger);
Trigger HTML markup
You can pass all options as data attributes with mt
prefix. Option name should be written in kebab case format, for example:
<a href="#target" class="js-trigger" data-mt-duration="300">Trigger</a>
<!-- Or -->
<button type="button" class="js-trigger" data-target="#target" data-mt-duration="300">Trigger</button>
The default options are as follows:
new MoveTo({
tolerance: 0,
duration: 800,
easing: 'easeOutQuart',
container: window
})
Option | Default | Desctiption |
---|---|---|
tolerance | 0 | The tolerance of the target to be scrolled, can be negative or positive |
duration | 800 | Duration of scrolling, in milliseconds |
easing | easeOutQuart | Ease function name |
container | window | The container been computed and scrolled |
callback | noop | The function to be run after scrolling complete. Target passes as the first argument |
Start scroll animation from current position to the anchor point
Type: HTMLElement|Number
Target element/position to be scrolled. Target position is the scrolling distance. It must be negative if the upward movement is desired.
Type: Object
Pass custom options.
Type: HTMLElement
This is the trigger element for starting to scroll when on click.
This is the callback function to be run after the scroll complete. This will overwrite the callback option.
Adds custom ease function.
Type: String
Ease function name.
Type: Function
Ease function. See Easing Equations for more ease function.
document.addEventListener('DOMContentLoaded', function () {
const easeFunctions = {
easeInQuad: function (t, b, c, d) {
t /= d;
return c * t * t + b;
},
easeOutQuad: function (t, b, c, d) {
t /= d;
return -c * t* (t - 2) + b;
}
}
const moveTo = new MoveTo({
duration: 1000,
easing: 'easeInQuad'
}, easeFunctions);
const trigger = document.getElementsByClassName('js-trigger')[0];
moveTo.registerTrigger(trigger);
});
document.addEventListener('DOMContentLoaded', function () {
const moveTo = new MoveTo({
duration: 1000,
callback: function (target) {
// This will run if there is no overwrite
}
});
const trigger = document.getElementsByClassName('js-trigger')[0];
moveTo.registerTrigger(trigger, function (target) {
// Overwrites global callback
});
// Or
moveTo.move(1200, {
duration: 500,
callback: function () {
// Overwrites global callback
}
});
});
document.addEventListener('DOMContentLoaded', function () {
const moveTo = new MoveTo();
const trigger = document.getElementsByClassName('js-trigger')[0];
// Register a trigger
const unregister = moveTo.registerTrigger(trigger, { duration: 500 });
// Unregister a trigger
unregister();
});
document.addEventListener('DOMContentLoaded', function () {
const moveTo = new MoveTo();
const triggers = document.getElementsByClassName('js-back-to-top');
for (var i = 0; triggers.length < i; i++) {
moveTo.registerTrigger(triggers[i]);
}
});
<a href="#" class="js-back-to-top" data-mt-duration="300">Back to top!</a>
