# Exalidraw Backend
|
||||||
|
|
||||||
|
Frustrated on how difficult it is to setup excalidraw self-hosted but with data
|
||||||
|
storage and collaboration function this represents and attempt to run the
|
||||||
|
necessary function with a single binary implemented in go.
|
||||||
|
|
||||||
|
Apply the patch to the frontend and build excalidraw. Run Excalidraw frontend and
|
||||||
|
on the same host run
|
||||||
|
```bash
|
||||||
|
go run main.go
|
||||||
|
