What’s New

ExtReact 6.6 Support

Themer 1.3.3 supports theming ExtReact 6.6 applications using the latest React 16.x framework and Web Pack 4 plugin. ExtReact components are themable without having to write any code, which is great for React developers. Material theme is popular amongst React developers and all ExtReact components have full support for Material theme. With Themer 1.3.3 you can style new modern components – Time Panel, Time Field, Gauges with needles and visually create uniquely themed components for your React application.

ExtReact Application Generator Support

Themer 1.3.3 supports theming applications created using the ExtReact Application Generator that you can install using the below command:

npm install -g  @sencha/ext-react-gen

You can specify Material, Triton, iOS or Neptune as the base theme while creating applications using the ExtReact Application Generator. For example, the below command creates a React application using the Triton theme:

ext-react-gen app --theme triton --name ThemerTritonApp

The ext-react-gen generator will ask if you’d like to include some example code in your app. If this is your first time using ExtReact, we suggest you include the example code so you can see how some of the more common components work.

You can use Themer to create a new theme by selecting the path to your ExtReact generated app in Themer. To add additional themes to your application, you will need to install corresponding theme packages in your application. For example, to add the Material theme package to an app that is currently using the Triton theme, use the following command:

npm i @sencha/ext-modern-theme-material  --save

  • You will need to restart “npm start” or “npx sencha app watch -fashion” after creating the new theme within the application workspace.
  • ExtReact currently does not support Fashion for React applications, so you will need to reload your application in the browser to see changes as you customize your theme.

Style ExtReact Components uniquely

Themer 1.3.3 supports creating multiple visual renditions of the same ExtReact component using a prop called “ui”. The example below shows that you can create “text-field-ui” in Themer and use in your React application, as follows:
this.query = field}
