DevExtreme Angular - DevExtreme CLI

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

• Node.js v12.6.0 or later
• npm v6.2.0 or later

npm i -g devextreme-cli

Alternatively, you can use npx to execute DevExtreme CLI commands without installing the CLI globally. Examples in this article illustrate both approaches.

Add the DevExtreme layout template to an existing Angular application:

devextreme add angular-template [--layout][--empty][--resolve-conflicts]
// ===== or =====
npx devextreme-cli add angular-template [--layout][--empty][--resolve-conflicts]

Arguments:

• --layout
  Specifies the DevExtreme layout to add. Available values:

  • side-nav-outer-toolbar (default)
  • side-nav-inner-toolbar

  Both layouts are illustrated in the Layouts article.

• --empty
  Specifies whether to skip sample views generation (default: false).

• --resolve-conflicts
  Specifies whether to override the existing app.component or create a component with another name. Available values:

  • createNew (default)
  • override (NOTE: all changes in the overridden files will be lost)

  If you created a new component, register it in app.module.ts:

  app.module.ts

  // ...
  import { AppComponent } from './app1.component';
  // ...

The following command adds a view to an application that uses the DevExtreme layout template:

devextreme add view view-name [--icon]
// ===== or =====
npx devextreme-cli add view view-name [--icon]

Arguments:

• --icon
  Specifies the view's icon (default: folder). You can choose an icon from the DevExtreme icon library.

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.

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

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]

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": "23.2.10",
    "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]

• --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).

Generate a new custom color swatch that uses Generic Dark as a base theme:

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:

npx devextreme-cli build-theme --base-theme="material.blue.light" --input-file="pink.json" --output-color-scheme="pink"

Export base variables for the Generic Carmine theme in LESS format:

npx devextreme-cli export-theme-vars --base-theme="generic.carmine" --output-format="less" --base
