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.
parcel-codegen-loader
Advanced tools
A plugin for Webpack (v4 and higher) to generate useful modules at bundle-time.
The parcel-codegen-loader
resolves import
/ require()
on a file into a Node.js module that is evaluated during the compilation. It expects the Node.js module to generate a webpack module on the fly establishing meta programming.
It follows pretty much the parcel-plugin-codegen implementation.
To begin, you'll need to install parcel-codegen-loader
:
npm install parcel-codegen-loader --save-dev
Import (or require
) the target file(s) in one of the bundle's files:
file.js
import { entries } from './file.codegen';
where file.codegen
could be written as follows:
module.exports = function() {
const entries = [1, 2, 3];
return `export const entries = ${JSON.stringify(entries)};`;
};
Then add the loader to your webpack
config. For example:
webpack.config.js
module.exports = {
module: {
rules: [
{
test: /\.codegen$/i,
use: [
{
loader: 'parcel-codegen-loader',
},
],
},
],
},
};
And run webpack
via your preferred method. This will emit file.png
as a file
in the output directory (with the specified naming convention, if options are
specified to do so) and returns the public URI of the file.
ℹ️ By default the filename of the resulting file is the hash of the file's contents with the original extension of the required resource.
(No options yet.)
The following examples show how one might use parcel-codegen-loader
and what the result would be.
Let's say you want to get a static set of users for your module from an API.
remote.codegen
const axios = require('axios');
module.exports = async function() {
const res = await axios.get('https://jsonplaceholder.typicode.com/users');
const users = res.data.map(m => ({ id: m.id, name: m.name, mail: m.email }));
return `export const users = ${JSON.stringify(users)};`;
};
You can now use the following code to retrieve this static info:
import { users } from './remote.codegen';
