@shelf/aws-lambda-libreoffice

aws-lambda-libreoffice

85 MB LibreOffice to fit inside AWS Lambda compressed with Brotli

Inspired by chrome-aws-lambda

:information_source: Compiled LibreOffice version: 6.4.0.1

Install

$ yarn add @shelf/aws-lambda-libreoffice

NOTE: Since version 2.0.0 npm package no longer ships the 85 MB LibreOffice but relies upon libreoffice-lambda-layer instead. Follow the instructions on how to add a lambda layer in that repo.

Usage

const {convertTo, canBeConvertedToPDF} = require('@shelf/aws-lambda-libreoffice');

module.exports.handler = async () => {
  // assuming there is a document.docx file inside /tmp dir
  // original file will be deleted afterwards

  if (!canBeConvertedToPDF('document.docx')) {
    return false;
  }

  return convertTo('document.docx', 'pdf'); // returns /tmp/document.pdf
};

Or if you want more control:

const {unpack, defaultArgs} = require('@shelf/aws-lambda-libreoffice');

await unpack(); // default path /tmp/instdir/program/soffice.bin

execSync(
  `/tmp/instdir/program/soffice.bin ${defaultArgs.join(
    ' '
  )} --convert-to pdf file.docx --outdir /tmp`
);
