Use keyboard shortcuts to become more productive while using Whiteboard.
They are especially useful if you work with interactive displays such as XP-Pen Artist, Huion Kamvas and Wacom Cintiq. These devices have quick buttons (6-8 buttons and scrolling). By default, the buttons on these displays are mapped to standard Photoshop keyboard shortcuts. Keys can be configured to function effectively in other software.
The following are predefined shortcuts that you can override in the file ./src/js/keybinds.js

Call your site with GET parameters to change the WhiteboardID or the Username
http://YOURIP:8080?whiteboardid=MYID&username=MYNAME
- whiteboardid => All people with the same ID are drawing on the same board
- username => The name which will be shown to others while drawing
- title => Change the name of the Browser Tab
- randomid => if set to true, a random whiteboardId will be generated if not given aswell
- copyfromwid => set this to a whiteboardId you want a copy from. Only copies the content if the current whiteboard is empty.
Many settings of this project can be set using a simple yaml file, to change some behaviors or tweak performances.
To run the project with custom settings:
- Create a
config.run.ymlfile based on the content ofconfig.default.yml, - Change the settings,
- Run the project with your custom configuration (it will be merged into the default one):
- locally:
node scripts/server.js --config=./config.run.yml - docker:
docker run -d -p 8080:8080 -v $(pwd)/config.run.yml:/config.run.yml:ro rofl256/whiteboard --config=/config.run.yml
To prevent clients who might know or guess the base URL from abusing the server to upload files and stuff, you can set an accesstoken at server start (see here).
Then set the same token on the client side as well:
Client (With and without docker): http://YOURIP:8080?accesstoken=mySecToken&whiteboardid=MYID&username=MYNAME
Done!
You can fully control the whiteboard through a REST API. Explore and test the API for your server version by surfing to: [yourRootWhiteboardUrl]/apidoc/index.html
You can see the API for the Demowhiteboard here: DemoAPI
Note: This API is pretty new, so be sure to use the latest Whiteboard version.
This function allows your users to save the whiteboard directly to a webdav server (Nextcloud) as image without downloading it.
To enable set enableWebdav to true in the configuration.
Then set the same parameter on the client side as well:
Client (With and without docker): http://YOURIP:8080?webdav=true&whiteboardid=MYID&username=MYNAME
Refresh the site and You will notice an extra save button in the top panel. Set your WebDav Parameters, and you are good to go!
Note: For the most owncloud/nextcloud setups you have to set the WebDav-Server URL to: https://YourDomain.tl/remote.php/webdav/
Done!
Many more settings can be tweaked. All of them are described in the default config file.
- Whiteboards are gone if you restart the Server enable "enableFileDatabase" in the config file or export the board to prevent that.
- You should be able to customize the layout without ever touching the whiteboard.js (take a look at index.html & main.js)
Add this to your server part:
location /whiteboard/ {
proxy_set_header HOST $host;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection upgrade;
proxy_pass http://YOURIP:8080/;
}
To run it at /whiteboard. Don't forget to change -> YOURIP!
<VirtualHost example.org:443>
...
# Proxy /whiteboard/ to whiteboard container
ProxyPass "/whiteboard/" "http://YOURIP:8080/"
ProxyPassReverse "/whiteboard/" "http://YOURIP:8080/"
...
</VirtualHost>
To run it at /whiteboard. Don't forget to change -> YOURIP!
- Install this app on your server
- Enable and go to "external sites" (app) on your Nextcloud
- Add a link to your server:
https://YOURIP/whiteboard/?whiteboardid=WHITEBOARDNAME&username={uid}You can give each group its own whiteboard by changeing the WHITEBOARDNAME in the URL if you want.
Note: You might have to serve the app with https (If your nextcloud server runs https). To do so, its recommend to run this app behind a reverse proxy. (as shown above)
Upload both icons present at /doc/nextcloud_icons/ to your nextcloud at the "external sites" admin section. Then set it as symbol on your link.
