Deploy your application on the server
Once you have finished integrating Dynamic Web TWAIN in your application, you can deploy it on your server to test it. As far as Dynamic Web TWAIN is concerned, all related files are to be served as static files which makes the deployment very easy.
How-to
The Resources folder is typically found in the following location after the installation:
- Windows: C:\Program Files (x86)\Dynamsoft\Dynamic Web TWAIN SDK {Version Number}\
- macOS: Applications > Dynamsoft > Dynamic Web TWAIN SDK {Version Number}
The deployment of Dynamic Web TWAIN is easy. Simply copy the Resources folder to your web server. Learn more on Set ResourcesPath
Technical details
Make sure the static files can be served correctly
Dynamic Web TWAIN comes with lots of static resources files, for the full list, check out What are the Resources files. The following table shows each file type and its MIME type which must be configured in your webserver in order for that type of file(s) to be correctly served to the client browsers.
| File Type | MIME Type | Required by |
|---|---|---|

Enable HTTPS
If you need to use any of the following features, you must enable HTTPS on the server.
- Upload or Download via SSL
- Any other features that require a secure connection
For how to enable HTTPS, please check out the manual of your webserver.
Set ResourcesPath
The global API Dynamsoft.DWT.ResourcesPath sets a relative or absolute path that tells Dynamic Web TWAIN where to look for the resources files at runtime. Its default value is Resources which means all these files are put in a directory called Resources that is in the same location as the web page on which Dynamic Web TWAIN is running. This is the simplest situation possible. However, in most cases, it’s a lot more complicated and you must make sure the correct value is set.
How to know ResourcesPath is wrong
When you set ResourcesPath wrong, static files such as dynamsoft.webtwain.install.js , dynamsoft.viewer.css will fail to load and you see 404 errors in the browser console.
Change ResourcePath using an absolute path
If you wish to use an absolute path to include the library, this is supported.
<script src="https://www.dynamsoft.com/dwt/demo/Resources/dynamsoft.webtwain.initiate.js"></script>
<script src="https://www.dynamsoft.com/dwt/demo/Resources/dynamsoft.webtwain.config.js"></script>
Note: If you want to use the Camera module, please make sure the absolute path stays in the same domain to avoid cross-origin issues.

If you do not wish to use an absolute path, learn more on how to change the reference path.
