## Installation
**Using `npx`**
If you don't want to install the CLI but just execute it, you can use it through `npx` this way
```sh
npx prisma-uml --help
```
**Install with `npm`**
You can also install the CLI globally
```sh
npm i -g prisma-uml
prisma-uml --help
```
## Commands
### `prisma-uml [options]`
> **Generate a plantUML from a Prisma schema**
```sh
prisma-uml [--output] [--server] [--file]
```
**Argument**
| Name | Description |
|----------|------------------------|
| **path** | Path to Prisma schema. |
**Options**
| Name | Alias | Description | Type / Choices | Default |
|--------------|-------|--------------------------------------|--------------------------------------|-----------------------------------|
| **--output** | -o | Output of the diagram | string / [text \| svg \| png \| jpg] | text |
| **--server** | -s | PlantUML Server URL | string | https://www.plantuml.com/plantuml |
| **--file** | -f | Filename or File full path to output | string | |
Examples
```sh
# Output a plantUML Entity Relation Diagram as text
prisma-uml ./schema.prisma
# Save the diagram into a .plantuml file
prisma-uml ./schema.prisma > my-erd.plantuml
# Output a diagram as SVG
prisma-uml ./schema.prisma --output svg --file my-erd.svg
# Output a diagram as PNG
prisma-uml ./schema.prisma -o png -f my-erd.png
# Use a plantUML custom server to render the image
prisma-uml ./schema.prisma --server http://localhost:8080
```
## Image Rendering
### Using the official PlantUML server online
PlantUML usually requires to have Java installed or a server to render the images. By default the official online server (https://www.plantuml.com/plantuml) is used to render the images. The plantUML diagram is first compressed then encoded ([plantUML encoding](https://plantuml.com/fr/code-javascript-synchronous)) and finally sent to the server to execute the rendering.
### Using a local server with Docker
You might want to avoid sending your diagram over the wire for some reason, `prisma-uml` allows you to specify a custom/local server. You could easily run your own local server using Docker:
```sh
docker run -d -p 8080:8080 plantuml/plantuml-server:jetty
```
You server is now available (depending of you Docker installation) at `http://localhost:8080`. You can then use `prisma-uml` as follow:
```sh
prisma-uml ./schema.prisma --server http://localhost:8080
```
