# @lfk/document-server

The document generation server responsible for creating pdfs for sponsoring contracts, certificates and more.
This server doesn't interact with any database and can therefor be deployed on it's own.
The basic generation mechanism makes the templates and routes interchangeable (if you want to expand or modify it).

## Quickstart 🐳
> Use this to run the document server in docker.

1. Clone the repo or copy the docker-compose 
2. Run in the folder that contains the docker-compose file: `docker-compose up -d`
3. Visit http://127.0.0.1:4010/docs to check if the server is running

## Dev Setup 🛠
> Local dev setup

1. Rename the .env.example file to .env (you can adjust app port and other settings, if needed)
2. Install Dependencies
   ```bash
   yarn
   ```
3. Start the server
   ```bash
   yarn dev
   ```

## ENV Vars
> You can provide them via .env file or docker env vars.

| DISCLAIMER_TEXT | String | N/A | A disclaimer that will get displayed on the bottom of each sponsoring contract. R/N You can only provide the disclaimer for one language.

## Templates
> The document server uses html templates to generate various pdf documents.
> The templates are stored in src/templates by default.

We provide a set of default templates that we use for the ["Lauf für Kaya!" charity run](https://lauf-fuer-kaya.de).
We use handlebars for templateing utilizing i18next for translation - the i18n string format in the templates is : `{{__ "string"}}`
You can provide your own templates by replacing the ones we provided before compiling the project or by simply mounting your custom templates into the docker container.

The server currently needs the following templates to work:
* sponsoring_contract.html

### Sponsoring Contracts

| Template Data | Type | Optional | Description
| - | - | - | -
| runners | array(Runner) | ❌ | The runner objects. We generate a contract for each runner on a new DIN-A5 page.
