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.
@evolv/mutate
Advanced tools
Mutate is a library of helpers to maintain persistent modifications to the rendered DOM of a web page for implementation of temporary, experimental changes and features for rapid experimentation.
It is intended to be framework independent and equally effective for SPAs and traditionally rendered webpages.
$ npm install @evolv/mutate
Clone the repository and run the following commands.
$ npm install
$ npm run build
There is a demo site included.

$ npm run demo
The API for Mutate is similar in a lot of ways to the API of jQuery
with a significant difference, that is selectors (Collectors
) refer
to all current and future matching Element
s, and the functions to modify
the DOM (Mutations
) are persistent.
This means that you don't need to worry about timing, or dynamic areas of the rendered page.
Mutate also provides the ability to "project" Element
s of the DOM into
other Element
s of the DOM, binding all interactions with the "projection"
back to the original Element
s.
As everyone building variants have learned the hard way, most Element
s
are dependent on their location in the DOM for both style and functionality.
Projection allows the implementer to "move" and restyle Element
s without
losing the position dependent functionality of the original Element
s.
import {collect, mutate} from '@evolv/mutate';
The basic flow when using Mutate is to first define a Collector.
collect('<selector>', '<collector name>');
Then to define a Mutator for the Collector.
mutate('<collector name>').hide();
Mutators allow for Mutations to be chained together, similar to jQuery which will be evaluated in order of invocation.
mutate('<collector name>').text('<new text value>').classes({'<new class>': true});
<script src="http://localhost:8080/index.js"></script>
(make sure that your local is running on 8080, otherwise update src)evolv.collect('h1', 'heading')
evolv.mutate('heading').html('Test');
