Office convert server

Simple server for converting office file formats into PDF files built on top of LibreOffice

Requirements

Requires LibreOffice and LibreOfficeKit

Debian:

sudo apt-get install libreoffice libreofficekit-dev clang

[!NOTE] On Debian bullseye you may not have the latest version of the libreofficekit-dev package which will likely cause the build to fail due to missing functions. I recommend building using Fedora or using Debian Bookworm with the "Bookworm Backports" package repo, which you can add using the following command:

echo "deb http://deb.debian.org/debian bookworm-backports main" | sudo tee /etc/apt/sources.list.d/bookworm-backports.list > /dev/null 

The install libreofficekit-dev through that package repo:

sudo apt-get -t bookworm-backports install -y libreofficekit-dev

Fedora:

sudo dnf install libreoffice libreoffice-sdk libreofficekit-devel clang

Ensure you set the following environment variable:

export LO_INCLUDE_PATH=/usr/include/LibreOfficeKit

Env variables

The server requires the following environment variables.

.env files will be loaded from the same and parent directories of the server

SERVER_ADDRESS=0.0.0.0:3000
LIBREOFFICE_SDK_PATH=/usr/lib64/libreoffice/program

Update LIBREOFFICE_SDK_PATH your specific LibreofficeSDK path. This is NOT your Libreoffice path

Building with docker

You can build the binary within docker using the following steps:

Build docker image

Build the docker image from the Dockerfile

docker build -t office_convert .

Create temp container

Create a temporary container for the converter

docker create --name temp_container office_convert

Copy binary from temp container

Then copy the binary from the container to your host:

docker cp temp_container:/app/office-convert-server ./office-convert-server

Cleanup the temp container

Once you have the binary on your host, you can remove the temporary container:

docker rm temp_container
