Threat Actor Exposes Playbook for Exploiting npm to Build Blockchain-Powered Botnets
A threat actor's playbook for exploiting the npm ecosystem was exposed on the dark web, detailing how to build a blockchain-powered botnet.
detect-indent
Advanced tools
The detect-indent npm package is designed to analyze a given piece of text and determine the indentation style used. This can be particularly useful in scenarios where maintaining consistent code formatting is crucial, such as in collaborative coding projects. It can detect both spaces and tabs used for indentation and provide information about the most used indentation type and size.
Detecting indentation from a string
This feature allows you to pass a string of text to the `detectIndent` function, which analyzes the indentation used in the text. It returns an object containing the amount of indentation, the type of indentation (spaces or tabs), and the actual indentation string.
const detectIndent = require('detect-indent');
const code = ' const x = 1;\n const y = 2;';
const indent = detectIndent(code);
console.log(indent); // {amount: 2, type: 'space', indent: ' '}
The indent-string package is used for adding indentation to strings. While detect-indent is focused on detecting and analyzing indentation, indent-string allows you to modify strings by adding a specified amount of indentation. This makes indent-string complementary to detect-indent, as you could detect indentation with one and apply it with the other.
Strip-indent is designed to remove leading indentation from every line in a string. This is somewhat the inverse of what detect-indent does; while detect-indent identifies the indentation style and level, strip-indent removes it entirely. This can be useful in preprocessing text to normalize indentation before further processing or display.
Detect the indentation of code
Pass in a string of any kind of text and get the indentation.
Download manually or with a package-manager.
$ npm install --save detect-indent
$ bower install --save detect-indent
$ component install sindresorhus/detect-indent
Accepts a string and returns the indentation or null
if it can't be detected.
Modify a JSON file while persisting the indentation in Node.js.
var fs = require('fs');
var detectIndent = require('detect-indent');
/*
{
"ilove": "pizza"
}
*/
var file = fs.readFileSync('foo.json', 'utf8');
// tries to detect the indentation and falls back to a default if it can't
var indent = detectIndent(file) || ' ';
var json = JSON.parse(file);
json.ilove = 'unicorns';
fs.writeFileSync('foo.json', JSON.stringify(json, null, indent));
/*
{
"ilove": "unicorns"
}
*/
