PDF Made Easy (PME) is a CLI application for building and developing PDF documents.

• A CLI you use to design and generate PDFs on your local machine using Liquid templates and YAML data files. Under the hood, it uses Puppeteer to create the PDFs.
• Something I created because I wanted to generate PDFs using the familiar HTML and CSS that I know.

• A library you use to incorporate into your scripts.
• Something you use on your server to generate PDFs on the fly. It's not very efficient to use a whole browser instance just to do that, using something like PDFKit, @pdfme/pdf-lib, or MuhammaraJS would probably be better.

• Node.js, preferably the latest Maintenance release or later.

npm install --global pdf-made-easy

npm install pdf-made-easy

pme
pme [options]
pme <command> [options]

Commands:
  pme        Same as 'dev' command                                     [default]
  pme dev    Watch data and template files and output PDF on change
  pme build  Output PDF using data and template files

Options:
  -h, --help      Show help                                            [boolean]
  -v, --version   Show version number                                  [boolean]
  -c, --config    Path to JavaScript config file                        [string]
  -d, --data      Path to YAML data file          [string] [default: "data.yml"]
  -o, --output    Path to PDF output file       [string] [default: "output.pdf"]
  -t, --template  Path to Liquid template file
                                           [string] [default: "template.liquid"]

Examples:
  pme
  pme -d info.yml
  pme dev -t ./templates/default.liquid
  pme build -o /home/user/document.pdf
  pme -d info.yml -t ./templates/default.liquid -o /home/user/document.pdf

You may want to specify options to change the default behavior of the libraries that this CLI uses. For that, you can create a JavaScript config file that exports a config object at the current working directory where you will invoke pme or point to one using the --config or -c flag. By default, pme will try to find pme.config.js, pme.config.mjs, and pme.config.cjs in the current working directory, in that order.

Let's say you don't want the Chrome instance Puppeteer will use to be sandboxed, you want to be notified when you don't set variables in your YAML config file that your Liquid template expects, and you want your PDF to be in landscape. You can create a pme.config.mjs with the following contents:

import { defineConfig } from "pdf-made-easy";

export default defineConfig({
	launchOptions: { args: ["--no-sandbox"] },
	liquidOptions: { strictVariables: true },
	pdfOptions: { landscape: true },
});

defineConfig is a helper to give you autocompletion and to check that you've provided the correct config keys. All of these settings are optional, you can provide some, a few, or none of them. Below are links to further documentation for what other options you can set:

• launchOptions
• liquidOptions
• pdfOptions

Note: For launchOptions, handleSIGHUP, handleSIGINT, and handleSIGTERM are always set to false since pme handles those signals itself. As for pdfOptions, path is always set to what is passed to the --output or -o flag.
