DevExtreme jQuery - DevExtreme CLI

DevExtreme CLI is a set of command-line tools to be used with the DevExtreme controls library.

ThemeBuilder

The ThemeBuilder UI is a tool that allows you to create custom themes in the browser; its CLI counterpart allows you to do the same with commands.

IMPORTANT

If your application uses npm v7 or later, open package.json and ensure the following:

  • The devextreme package is listed in dependencies.
  • The devextreme-themebuilder package is listed in devDependencies.
  • Both packages have the same version.

If these conditions are not met, run the following commands to install the packages:

npm i devextreme@23.2 --save --save-exact
npm i devextreme-themebuilder@23.2 --save-dev --save-exact

Build a Custom Color Scheme

devextreme build-theme [--base-theme][--input-file][--make-swatch][--output-file][--version][--widgets][--assetsBasePath][--output-color-scheme][--help]
// ===== or without installing the DevExtreme CLI =====
npx devextreme-cli build-theme [--base-theme][--input-file][--make-swatch][--output-file][--version][--widgets][--assetsBasePath][--output-color-scheme]

Export Theme Variables

The following command exports theme variables as a .less or .scss file:

devextreme export-theme-vars [--base-theme][--input-file][--output-format][--output-file][--version][--base][--help]
// ===== or =====
npx devextreme-cli export-theme-vars [--base-theme][--input-file][--output-format][--output-file][--version][--base]

Export Theme Metadata

Theme metadata is a JSON object that describes the theme. It is used to export or import a theme in the ThemeBuilder UI. Below is an example of theme metadata.

{
    "items": [
        {
            "key": "$base-text-color",
            "value": "rgba(94, 33, 33, 0.87)"
        },
        {
            "key": "$base-accent",
            "value": "rgba(64, 156, 199, 1)"
        }
    ],
    "baseTheme": "material.blue.light.compact",
    "outputColorScheme": "custom-scheme",
    "makeSwatch": true,
    "version": "23.2.5",
    "widgets": ["datagrid","treelist","selectbox"],
    "assetsBasePath": "../../../node_modules/devextreme/dist/css/"
}

The metadata object contains the following properties:

  • items
    An array that describes customized theme variables.

    • key
      A theme variable's name.
    • value
      The theme variable's value.
  • baseTheme
    A predefined DevExtreme theme which the custom theme is based on.

  • outputColorScheme
    The custom theme's color scheme.

  • makeSwatch
    A flag that indicates whether the theme is a color swatch.

  • version
    The target DevExtreme version.

  • widgets
    A list of UI components whose styles are included in the resulting CSS file.

  • assetsBasePath
    A path to the folder that contains the DevExtreme icons and fonts folders. This property is used only if the icons and fonts are not in the same folder as your custom theme.

Run the following command to export the metadata as a .json file:

devextreme export-theme-meta [--base-theme][--input-file][--output-file][--base][--help]
// ===== or =====
npx devextreme-cli export-theme-meta [--base-theme][--input-file][--output-file][--base]

Command-Line Arguments

  • --base-theme
    Specifies a base theme's name (default: generic.light).

  • --input-file
    Specifies the name of the file that contains input data (a .json file with metadata or a .less or .scss file with Bootstrap variables).

  • --output-file
    Specifies the output file name.

  • --output-format
    Specifies the format of the output variables: less or scss (default: less or the extension extracted from the --output-file value (if it contains any)).

  • --output-color-scheme
    Specifies the custom color scheme name (default: custom-scheme).

  • --make-swatch
    When present, creates a color swatch, i.e., adds a CSS scope to each CSS rule (.dx-swatch-xxx, where xxx is the value from the --output-color-scheme parameter).

  • --base
    Exports only base variables used to produce derived variables.

  • --version
    Specifies the target DevExtreme version or a tag that points to it (the default value is latest).

  • --widgets
    Specifies a comma-separated list of UI components whose styles should be included in the resulting CSS file. If this argument is not specified, styles of all UI components are included. Syntax example:

    --widgets=datagrid,treelist,selectbox
  • --assetsBasePath
    Specifies a path to the folder that contains the DevExtreme icons and fonts folders. Use this argument if the icons and fonts are not in the same folder as your custom theme.

  • --remove-external-resources
    When present, removes links to external resources, such as fonts. The theme will use local fallbacks instead.

  • --bootstrap-version
    Specifies Bootstrap version 4 or 5 if --input-file is a .scss file (default: 4).

npx devextreme-cli build-theme --base-theme="generic.dark" --make-swatch --output-color-scheme="custom"

Generate a new pink color scheme based on the Material Blue Light theme, use constants from the pink.json file:
