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.
The cli-ux npm package provides a set of utilities for building command-line interfaces (CLIs). It offers features such as progress bars, spinners, prompts, and table formatting to enhance the user experience of CLI applications.
Progress Bar
This feature allows you to display a progress bar in the terminal. The code sample demonstrates how to create and update a progress bar that increments by 5% every 100 milliseconds until it reaches 100%.
const cli = require('cli-ux');
const progress = cli.progress({ format: 'progress [{bar}] {percentage}% | ETA: {eta}s' });
progress.start(100, 0);
let value = 0;
const interval = setInterval(() => {
value += 5;
progress.update(value);
if (value >= 100) {
clearInterval(interval);
progress.stop();
}
}, 100);
Spinner
This feature provides a spinner to indicate ongoing processes. The code sample shows how to start a spinner with a message and stop it after 3 seconds with a 'done' message.
const cli = require('cli-ux');
cli.action.start('Processing');
setTimeout(() => {
cli.action.stop('done');
}, 3000);
Prompt
This feature allows you to prompt the user for input. The code sample demonstrates how to ask the user for their name and then greet them with the provided input.
const cli = require('cli-ux');
(async () => {
const name = await cli.prompt('What is your name?');
console.log(`Hello, ${name}!`);
})();
Table
This feature allows you to display data in a table format. The code sample shows how to create a table with two columns: 'name' and 'age', and display two rows of data.
const cli = require('cli-ux');
const data = [
{ name: 'John', age: 30 },
{ name: 'Jane', age: 25 }
];
cli.table(data, {
name: {
minWidth: 7
},
age: {
header: 'Age'
}
});
Ora is a lightweight and elegant terminal spinner. It provides similar functionality to the spinner feature in cli-ux but focuses solely on spinners, offering more customization options and better performance.
Inquirer is a powerful library for creating interactive command-line prompts. It offers more advanced and flexible prompt types compared to cli-ux, making it a better choice for complex user interactions.
Blessed is a comprehensive library for building terminal interfaces. It provides a wide range of widgets, including tables, forms, and more, offering greater flexibility and customization than cli-ux.
Progress is a simple and flexible progress bar library for Node.js. It offers similar functionality to the progress bar feature in cli-ux but with a more minimalistic approach and fewer dependencies.
