# @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.
|
||||
|
||||
| Name | Type | Default | Description
|
||||
| - | - | - | -
|
||||
| APP_PORT | Number | 4010 | The port the backend server listens on. Is optional.
|
||||
| NODE_ENV | String | dev | The apps env - influences debug info.
|
||||
|
||||
## 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.
|
||||
|
||||
|
||||
## Recommended Editor
|
||||
|
||||
[Visual Studio Code](https://code.visualstudio.com/)
|
||||
|
||||
### Recommended Extensions
|
||||
|
||||
* will be automatically recommended via ./vscode/extensions.json
|
||||
* we also provide a config for i18n-ally in the .vscode folder
|
||||
|
||||
## Staging
|
||||
### Branches & Tags
|
||||
* vX.Y.Z: Release tags created from the main branch
|
||||
* The version numbers follow the semver standard
|
||||
* A new release tag automaticly triggers the release ci pipeline
|
||||
* main: Protected "release" branch
|
||||
* The latest tag of the docker image get's build from this
|
||||
* New releases get created as tags from this
|
||||
* dev: Current dev branch for merging the different feature branches and bugfixes
|
||||
* The dev tag of the docker image get's build from this
|
||||
* Only push minor changes to this branch!
|
||||
* To merge a feature branch into this please create a pull request
|
||||
* feature/xyz: Feature branches - nameing scheme: `feature/issueid-title`
