# mermaid-server

Use mermaid-js to generate diagrams in a HTTP endpoint.

While this currently serves the diagrams via HTTP, it could easily be manipulated to server diagrams via other means.

## Basic usage

Start the HTTP server:
```
go run cmd/app/main.go --mermaid=./mermaidcli/node_modules/.bin/mmdc --in=./in --out=./out
```

Send CURL request to generate a diagram via `POST`:
```
curl --location --request POST 'http://localhost:80/generate' \
--header 'Content-Type: text/plain' \
--data-raw 'graph LR

    A-->B
    B-->C
    C-->D
    C-->F
'
```

Or send CURL request to generate a diagram via `GET`... send in url encoded data under the `data` query param:
```
curl --location --request GET 'http://localhost:80/generate?data=graph%20LR%0A%0A%20%20%20%20A--%3EB%0A%20%20%20%20B--%3EC%0A%20%20%20%20C--%3ED%0A%20%20%20%20C--%3EF%0A'
```
