This repository contains an Elixir application that exposes a small HTTP API for converting DOCX documents into BlockNote JSON. It also provides a companion Node based service that converts BlockNote blocks into Y.js updates.

• Elixir application – defined in mix.exs and built with Plug and Bandit. The main router lives in lib/docspec/api.ex and exposes a /conversion endpoint implemented in lib/docspec/api/controller/conversion.ex.
• Node service – located in blocknote-api and implemented in src/main.ts. This service listens for JSON blocks on port 9871 (configurable with the PORT environment variable) and returns a base64 encoded Y.js update.
• Docker setup – Dockerfile builds the Elixir release and docker-compose.yml wires the services behind Traefik.

The easiest way to run everything locally is with Docker:

docker-compose up --build

Alternatively you can build the Elixir release yourself:

mix deps.get
mix release
_build/prod/rel/docspec/bin/docspec start

Once running you can POST a DOCX file to convert:

curl -X POST http://localhost:4000/conversion -F "file=@path/to/document.docx"

The response body is the converted BlockNote JSON.

Elixir tests can be run with:

mix test
