Asynchronous node.js wrapper for the Poppler PDF rendering library
Poppler is a PDF rendering library that also includes a collection of utility binaries, which allows for the manipulation and extraction of data from PDF documents such as converting PDF files to HTML, TXT, or PostScript.
The node-poppler
module provides an asynchronous node.js wrapper around said utility binaries for easier use.
Install using npm
:
npm i node-poppler
Windows binaries are provided with this repository.
For Linux users, you will need to download the poppler-data
and poppler-utils
binaries separately.
An example of downloading the binaries on a Debian system:
sudo apt-get install poppler-data poppler-utils
For macOS users, you can download the latest versions with Homebrew:
brew install poppler
Please refer to the JSDoc comments in the source code or the generated type definitions for information on the available options.
Example of an async
await
call to poppler.pdfToCairo()
, to convert only the first and second page of a PDF file to PNG:
const { Poppler } = require("node-poppler");
const file = "test_document.pdf";
const poppler = new Poppler();
const options = {
firstPageToConvert: 1,
lastPageToConvert: 2,
pngFile: true,
};
const outputFile = `test_document.png`;
const res = await poppler.pdfToCairo(file, outputFile, options);
console.log(res);
Example of an async
await
call to poppler.pdfToCairo()
, to convert only the first of a PDF file to a new
PDF file using stdout:
const { writeFile } = require("node:fs/promises");
const { Poppler } = require("node-poppler");
const file = "test_document.pdf";
const poppler = new Poppler();
const options = {
lastPageToConvert: 1,
pdfFile: true,
};
const res = await poppler.pdfToCairo(file, undefined, options);
// pdfToCairo writes to stdout using binary encoding if pdfFile or singleFile options are used
await writeFile("new_file.pdf", res, { encoding: "binary" });
Example of calling poppler.pdfToHtml()
with a promise chain:
const { Poppler } = require("node-poppler");
const file = "test_document.pdf";
const poppler = new Poppler();
const options = {
firstPageToConvert: 1,
lastPageToConvert: 2,
};
poppler
.pdfToHtml(file, undefined, options)
.then((res) => {
console.log(res);
})
.catch((err) => {
console.error(err);
throw err;
});
Example of calling poppler.pdfToHtml()
with a promise chain, providing a Buffer as an input:
const { readFileSync } = require("node:fs");
const { Poppler } = require("node-poppler");
const file = readFileSync("test_document.pdf");
const poppler = new Poppler();
const options = {
firstPageToConvert: 1,
lastPageToConvert: 2,
};
poppler
.pdfToHtml(file, "tester.html", options)
.then((res) => {
console.log(res);
})
.catch((err) => {
console.error(err);
throw err;
});
Example of calling poppler.pdfToText()
with a promise chain:
const { Poppler } = require("node-poppler");
const file = "test_document.pdf";
const poppler = new Poppler();
const options = {
firstPageToConvert: 1,
lastPageToConvert: 2,
};
const outputFile = "test_document.txt";
poppler
.pdfToText(file, outputFile, options)
.then((res) => {
console.log(res);
})
.catch((err) => {
console.error(err);
throw err;
});
