## Default keyboard shortcuts
|
|
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 [/public/js/keybinds.js](https://github.com/cracker0dks/whiteboard/blob/master/public/js/keybinds.js)

|
|
You can run this app with and without docker
|
|
### Without Docker
|
|
1. install the latest NodeJs
|
|
2. Clone the app
|
|
3. Run `npm i` inside the folder
|
|
4. Run `node server.js`
|
|
5. Surf to http://YOURIP:8080
|
|
|
|
### With Docker
|
|
1. `docker run -d -p 8080:8080 rofl256/whiteboard`
|
|
2. Surf to http://YOURIP:8080
|
|
|
|
## URL Parameters
|
|
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 witch is showing to others while drawing
|
|
* title => Change the name of the Browser Tab
|
|
|
|
## Security - AccessToken (Optional)
|
|
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.
|
|
|
|
<b>Server (Without docker):</b> `node server.js --accesstoken="mySecToken"`
|
|
|
|
<b>Server (With docker):</b> `docker run -d -e accesstoken="mySecToken" -p 8080:8080 rofl256/whiteboard`
|
|
|
|
Then set the same token on the client side as well:
|
|
|
|
<b>Client (With and without docker):</b> `http://YOURIP:8080?accesstoken=mySecToken&whiteboardid=MYID&username=MYNAME`
|
|
|
|
Done!
|
|
|
|
## WebDAV (Optional)
|
|
This function allows your users to save the whiteboard directly to a webdav server (Nextcloud) as image without downloading it.
|
|
|
|
To enable it:
|
|
|
|
<b>Server (Without docker):</b> `node server.js --webdav=true`
|
|
|
|
<b>Server (With docker):</b> `docker run -d -e webdav=true -p 8080:8080 rofl256/whiteboard`
|
|
|
|
Then set the same parameter on the client side as well:
|
|
|
|
<b>Client (With and without docker):</b> `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!
|
|
|
|
|
|
## Things you may want to know
|
|
* Whiteboards are gone if you restart the Server, so keep that in mind (or save your whiteboard)
|
|
* You shoud be able to customize the layout without ever toutching the whiteboard.js (take a look at index.html & main.js)
|
|
|
|
## All server start parameters (also docker)
|
|
* accesstoken => take a look at "Security - AccessToken" for a full explanation
|
|
* disablesmallestscreen => set this to "true" if you don't want show the "smallest screen" indicator (A dotted gray line) to the users
|
|
* webdav => Enable the function to save to a webdav-server (Must also be enabled on the client; Take a look at the webdav section)
|
|
|
|
## ToDo
|
|
* Make undo function more reliable on texts
|
|
|
|
## Nginx Reverse Proxy configuration
|
|
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!
|
|
|
|
## Nextcloud integration
|
|
1. Install this app on your server
|
|
2. Enable and go to "external sites" (app) on your Nextcloud
|
|
2. 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)
|
|
|
|
#### (Optional) Set whiteboard icon in nextcloud
|
|
|
|
|
|
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.
