For reactUI, nightly builds are available [[https://github.com/sibvisions/reactUI/releases|here]]. It's easy to use nightly builds in your VisionX. 

**But be careful**, because it's not guaranteed that everything is compatible and it's also not officially supported. If you take the risk and test your application, it shouldn't be a big problem.

If you want to use a nightly build in your VisionX application, you have two options:

  * Update only one application
  * Update all applications

To update only one application, simply delete the content of ''//<VISIONX_DIR>/rad/apps/<APPNAME>/WebContent/ui//'', extract the nightly build archive and copy the content of build directory into the ''//<VISIONX_DIR>/rad/apps/<APPNAME>/WebContent/ui//'' directory. The advantage of updating only one application is that you can switch back to the old UI. A disadvantage is that automatic UI updates won't work if you have the ''.custom'' file in your UI directory.

To prevent automatic UI updates, create a file with name ''.custom'' in ''//<VISIONX_DIR>/rad/apps/<APPNAME>/WebContent/ui//'' directory.

To update all applications, simply delete the content of ''//<VISIONX_DIR>/rad/apps/visionx/resources/application/WebContent\ui//'', extract the nightly build archive and copy the content of build directory into the ''//<VISIONX_DIR>/rad/apps/visionx/resources/application/WebContent\ui//'' directory. Start or reastart VisionX and all applications should be automatically updated. A disadvantage is that it's not easily possible to switch back to the old UI. It's possible if you have a backup of the old UI directory.

A template for automatic updates of your application:

<file xml>
<target name="start.updateReactUI.nightly" description="Updates reactUI with nightly build">
  
  <tstamp>
    <format property="datepattern" pattern="dd_MM_yyyy"/>
    <!-- yesterday
    <format property="datepattern" pattern="dd_MM_yyyy" offset="-1" unit="day" />
    -->
  </tstamp>

  <get src="https://github.com/sibvisions/reactUI/releases/download/build-${datepattern}/reactBuild_${datepattern}.zip" 
       dest="${build}/nightly.zip" 
       usetimestamp="true"/>

  <!-- prepare nightly build archive extraction -->
  <delete file="${build}/nightly"/>
  <unzip src="${build}/nightly.zip" dest="${build}/nightly">

      <include name="build/*/**"/>
    </patternset>
    <mapper>
      <globmapper from="build/*" to="*"/>
    </mapper>
  </unzip>

  <!--  delete old files  -->
  <delete includeEmptyDirs="true">
