Working with Themes in React Native

You can style React Native apps using a theme. Common (theme) styles will greatly reduce the styling effort of individual apps. The following topics related to a theme are discussed in this article.

  1. How to create a theme
  2. Theme project structure
  3. Customizing a theme
  4. Compile a theme
  5. Update a theme
  6. Import a theme
  7. Multiple themes

Required Software

  • Node (18.16.1)
  • React Native Codegen: Run the below command in the terminal to install React Native Codegen.
npm install -g @wavemaker/rn-codegen

Creating a Theme

  • Open a terminal
  • Navigate to a directory where you wish to create a theme project
  • Execute the following command
wm-rn-codegen theme generate ${theme-name}
  • A new folder with the given theme name should get created.
  • Open file.
  • Provide value to name (required) and other metadata.
  • Push the theme project to your VCS (optional).

Theme Project Structure

Following is the folder structure of a theme project.

  • $ThemeProject

    • src

      • android - theme customizations specific to Android
      • ios - theme customizations specific to iOS
      • common - theme customizations that are common to both Android and iOS
    • theme.png - a picture that represents this theme

    • wavemaker - This folder contains all the default styles provided by WaveMaker React Native Framework. The WaveMaker platform maintains the contents of this folder. Therefore, avoid any modifications in this folder.

    • - information about the theme

Customize Theme

To understand customization, let's take the button as an example.

  • Go to $ThemeProject/wavemaker
  • For each widget, there is a less file inside the wavemaker folder. Copy button.less from wavemaker/components/basic/button.less to src/common/components/basic/button.less

Path structure should be the same in both wavemaker and src/common folders. If you need customizations for a specific platform, copy the file into src/platform_name

  • Open the copied file and change or add styles

Customizing theme colors

  • Open wavemaker/variables.less
  • Select the color that requires change.
  • Open src/common/variables.less. For a platform-specific change, open corresponding variables.less of that platform folder.
  • If @platformColor has to be changed, add a less variable with the name @_platformColor and assign the desired value. The new variable name must have an underscore between @ and variable name. For example, @_primaryColor will override the value of @primaryColor.

Compile Theme

  • Open a terminal
  • Navigate to the directory where the theme project is.
  • Execute the following command.
wm-rn-codegen theme compile
  • Under the dist folder, the file should get created after successful compilation.

Update Theme Project

  • Open a terminal
  • Navigate to the directory where the theme project is.
  • Execute the following command.
wm-rn-codegen theme update
  • Theme project: contents of the wavemaker folder migrates.

When @wavemaker/rn-codegen is updated, run theme update on the existing theme projects.

Import Theme into a Project

  • You can import the zip generated in the compiled step into a React Native project. For more information, see import and apply a theme.

Multi-theme Support

With Multi-theme support, you can choose multiple themes at the same time for an application using the Theme dialog, setting one theme as the default.

How to Apply Multiple Themes

  1. In WaveMaker Studio after importing themes using the Theme dialog.
  2. Select multiple themes from the themes available in the Themes window to be part of the application. Theme dialog

Get Theme Information

  • To know the names of the themes available in an application, use App.themes.
  • To check the name of the active theme in an application, use App.activeTheme.
  • For example, use the below code to construct a Select UI using the above values


<wm-select name="select1" 
dataset="bind:App.themes" datafield="All Fields"
on-change="select1Change($event, widget, newVal, oldVal)">


Page.select1Change = function($event, widget, newVal, oldVal) {
App.activeTheme = newVal;
