node-latex

Simple LaTeX wrapper for node.js

Installation

First, you need to install latex. On any Debian based system, you can do this with the following command:

sudo apt-get install texlive

On OS X, you will need to install MacPorts first. Once that is set up, you can then do:

sudo port install texlive

For Windows, you can try using cygwin though I have not tested this.

Once you have a working version of latex, you can install node-latex using the following command:

npm install latex

Usage

Here is an example of how to use the library in one line:

require("latex")([
  "\\documentclass{article}",
  "\\begin{document}",
  "hello world",
  "\\end{document}"
]).pipe(process.stdout)

This will spit out a formatted PDF article to stdout that says "hello world". The result of calling the function is returned as a stream and can be processed using other tools. If you want to convert the result into an image or pdf, you can use graphics magic.

require("latex")(doc[, options])

The only exported function from node-latex is a function that takes as input a raw LaTeX document and returns a stream representing the document state. The type of doc must be one of the following:

  • A string
  • A Buffer
  • An array of strings and/or Buffers
  • A readable Stream

In addition, you can also specify the following additional parameters via the options struct:

  • command: An optional override for the latex command. By default calls latex.
  • format: Either "pdf" or "dvi". By default returns a pdf.

The function returns a readable Stream object representing a LaTeX encoded document in either PDF or DVI format. If there were errors in the syntax of the document, they will be raised as errors on this Stream object.
