Hpdf NPM | npm.io

hpdf

NodeJS's library for generating PDF from HTML with pool of browsers (puppeteer) in the background.

There are enough NodeJS libraries to generate PDF from HTML. Why do you need another one?

There is no up-to-date libraries.
There is no libraries with pool (but we have to use pooling when we are talking about browser in the background)

Features:

Configurable pool of pages (as resources) in the background
Fully tested
Written in TypeScript

How it works

npm.io

Install

npm install hpdf

Usage

import fs from 'fs';
import { PdfGenerator } from './src';

const start = async () => {
    const generator = new PdfGenerator({
        min: 3,
        max: 10,
    });

    const helloWorld = await generator.generatePDF('<html lang="html">Hello World!</html>');
    const github = await generator.generatePDF(new URL('https://github.com/frimuchkov/hpdf'));

    await fs.promises.writeFile('./helloWorld.pdf', helloWorld);
    await fs.promises.writeFile('./github.pdf', github);

    await generator.stop();
}

Before using puppeteer you have to install an additional libs:

FROM node:16-alpine AS base

# Installs latest Chromium (89) package.
RUN apk add --no-cache \
      chromium \
      nss \
      freetype \
      harfbuzz \
      ca-certificates \
      ttf-freefont

# Tell Puppeteer to skip installing Chrome. We'll be using the installed package.
ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true \
    PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium-browser

WORKDIR /app
