LaTeX Cleaner for Web

A lightweight utility to strip unnecessary LaTeX layout tags and clean up text for web display. Great for parsing math problems or educational content.

I tried to change some PDF files including math problems into JSON file, and when converted by either 'file-system' or 'pdf-parse' npm module, the file keeps throwing either \n or \t, which are bit annoying. So, I make a simple function as a module anyone can use.

Features

• Removes layout commands like \bigskip, \newpage, \vfill, etc.
• Converts \\ (line breaks) to spaces.
• Removes standard LaTeX boilerplate.

Installation

npm install @jamesyhr/latex-cleaner

Usage

Old version

const clean = require('@jamesyhr/latex-cleaner');

const rawLatex = "Problem 1 \\bigskip \\textbf{Solve this:} $x^2 + y^2 = 1$ \\newpage";
const cleanText = clean(rawLatex);

console.log(cleanText);
// Output: "Problem 1 Solve this: $x^2 + y^2 = 1$"

Version 0.1.0+

const LatexCleaner = require('@jamesyhr/latex-cleaner');

const cleaner = new LatexCleaner();

const dirty = "\\noindent Hello \\\\ World \t \\bigskip";
const clean = cleaner.clean(dirty);

console.log(clean); // "Hello World"

You can use either method. If you check my index.js file, you can call the old "function" method and the new "class" method. Enjoy!
