*TeX Microservice

This container offers a little http service that allows to compile various *TeX sources without installing *TeX into your application container.

Usage

To start the container you can use the following command:

docker run -p 7000:7000 digilist/latex-microservice

The http service is now available under http://localhost:7000 and accepts your POST requests. You can specify your favorite tex compiler in the request path, e.g. http://localhost:7000/xelatex

Examples are given as curl commands.

Simple TeX compiling

This example posts the tex source to the service and receives the compiled PDF.

curl -X POST -d "`cat test.tex`" -H "Content-Type: text/plain" -H "Accept: application/pdf" http://localhost:7000/

JSON response with compiler output

By requesting JSON, the service will return the output of the compiler and the PDF as base64 encoded string.

curl -X POST -d "`cat test.tex`" -H "Content-Type: text/plain" -H "Accept: application/json" http://localhost:7000/

{
    "status": "success",
    "compiler_output": "b\"This is pdfTeX, Version 3.14159265-2.6-1.40.16...",
    "pdf: "b'JVBER....'"
}

Passing source as JSON

You can also POST a JSON object to the service. This allows you to pass further files (which need to be base64 encoded):

curl -X POST -d '{"tex_source": "\\documentclass{article}\n\n\\begin{document}\n\\include{test/test}\n\\end{document}", "files": {"test/test.tex": "aGFsbG8gd2VsdA=="}}' -H "Content-Type: application/json" -H "Accept: application/json" http://localhost:7000/
