StaticloadLibraries

• loadLibraries(options: LibraryLoadOptions): Promise<LibraryLoadResult>

  Load libraries with specific options (backward compatibility)

  Parameters

  • options: LibraryLoadOptions

  Returns Promise<LibraryLoadResult>

  Deprecated

StaticloadLibrariesWithDependencies

• loadLibrariesWithDependencies(
      libraryNames: string[],
      allLibraries: MJComponentLibraryEntity[],
      requestedBy?: string,
      options?: DependencyResolutionOptions,
  ): Promise<Map<string, any>>

  Load multiple libraries with dependency resolution

  Parameters

  • libraryNames: string[]

    Names of libraries to load

  • allLibraries: MJComponentLibraryEntity[]

    All available libraries for dependency resolution

  • requestedBy: string = 'user'

    Name of the component requesting these libraries

  • Optionaloptions: DependencyResolutionOptions

    Dependency resolution options

  Returns Promise<Map<string, any>>

  Map of library names to their loaded global objects

StaticloadLibraryWithDependencies

• loadLibraryWithDependencies(
      libraryName: string,
      allLibraries: MJComponentLibraryEntity[],
      requestedBy?: string,
      options?: DependencyResolutionOptions,
  ): Promise<any>

  Load a library with its dependencies

  Parameters

  • libraryName: string

    Name of the library to load

  • allLibraries: MJComponentLibraryEntity[]

    All available libraries for dependency resolution

  • requestedBy: string = 'user'

    Name of the component/library requesting this load

  • Optionaloptions: DependencyResolutionOptions

    Dependency resolution options

  Returns Promise<any>

  Promise resolving to the loaded library global object

StaticpreloadCoreScripts

• preloadCoreScripts(debug?: boolean): void

  Inject <link rel="preload" as="script"> tags for core runtime libraries (React, ReactDOM, Babel) so the browser starts downloading them immediately. Call this as early as possible (e.g., in index.html or APP_INITIALIZER).

  This is purely a hint — if the scripts are already cached or loaded, the browser ignores the hint. The actual loadAllLibraries() call still creates <script> tags and waits for execution; preload just ensures the bytes are in the HTTP cache by the time that happens.

  Parameters

  • debug: boolean = false

    Whether to preload development builds (default: false = production)

  Returns void
