# Excalidraw Complete: A Self-Hosted Solution
|
||||
|
||||
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. This includes:
|
||||
Excalidraw Complete simplifies the deployment of Excalidraw, bringing an
|
||||
all-in-one solution to self-hosting this versatile virtual whiteboard. Designed
|
||||
for ease of setup and use, Excalidraw Complete integrates essential features
|
||||
into a single Go binary. This solution encompasses:
|
||||
|
||||
- the frontend UI
|
||||
- a in-memory data layer
|
||||
- socket.io implementation for collaboration
|
||||
- The intuitive Excalidraw frontend UI for seamless user experience.
|
||||
- An integrated data layer ensuring fast and efficient data handling based on different data providers.
|
||||
- A socket.io implementation to enable real-time collaboration among users.
|
||||
|
||||
The project goal is to alleviate the setup complexities traditionally associated with self-hosting Excalidraw, especially in scenarios requiring data persistence and collaborative functionalities.
|
||||
|
||||
## Installation
|
||||
|
||||
To get started, download the latest release binary:
|
||||
|
||||
Apply the patch to the frontend and build excalidraw into `frontend`. Run
|
||||
```bash
|
||||
go run main.go
|
||||
# Visit https://github.com/PatWie/excalidraw-complete/releases/ for the download URL
|
||||
wget <binary-download-url>
|
||||
chmod +x excalidraw-complete
|
||||
./excalidraw-complete
|
||||
```
|
||||
|
||||
Everything will be served under `localhost:3002`
|
||||
Once launched, Excalidraw Complete is accessible at `localhost:3002`, ready for
|
||||
drawing and collaboration.
|
||||
|
||||
### Configuration
|
||||
|
||||
Excalidraw Complete adapts to your preferences with customizable storage solutions, adjustable via the `STORAGE_TYPE` environment variable:
|
||||
|
||||
- **Filesystem:** Opt for `STORAGE_TYPE=filesystem` and define `LOCAL_STORAGE_PATH` to use a local directory.
|
||||
- **SQLite:** Select `STORAGE_TYPE=sqlite` with `DATA_SOURCE_NAME` for local SQLite storage, including the option for `:memory:` for ephemeral data.
|
||||
- **AWS S3:** Choose `STORAGE_TYPE=s3` and specify `S3_BUCKET_NAME` to leverage S3 bucket storage, ideal for cloud-based solutions.
|
||||
|
||||
These flexible configurations ensure Excalidraw Complete fits seamlessly into your existing setup, whether on-premise or in the cloud.
|
||||
|
||||
## Building from Source
|
||||
|
||||
Interested in contributing or customizing? Build Excalidraw Complete from source with these steps:
|
||||
|
||||
```bash
|
||||
# Clone and prepare the Excalidraw frontend
|
||||
git clone https://github.com/excalidraw/excalidraw.git
|
||||
cd excalidraw
|
||||
git checkout tags/v0.17.3
|
||||
git apply ../frontend.patch
|
||||
# Follow build instructions to compile assets into the frontend directory
|
||||
```
|
||||
|
||||
Compile the Go application:
|
||||
|
||||
```bash
|
||||
go build -o excalidraw-complete main.go
|
||||
```
|
||||
|
||||
Start the server:
|
||||
|
||||
```bash
|
||||
./excalidraw-complete
|
||||
```
|
||||
|
||||
Excalidraw Complete is now running on your machine, ready to bring your collaborative whiteboard ideas to life.
|
||||

|
||||
|
||||
Excalidraw is a fantastic tool, but self-hosting it can be tricky. I welcome
|
||||
your contributions to improve Excalidraw Complete — be it through adding new
|
||||
features, improving existing ones, or bug reports.
