(NII-Proposal) add plugin architecture for file actions #841

yacchin1205 · 2026-01-05T13:09:47Z

This Draft Pull Request is for reference purposes. The details will be discussed in the COS-NII meeting.

Ticket: []
Feature flag: n/a

Purpose

Add a plugin architecture for file browser actions (context menu and toolbar). Extensions are included in the codebase but can be enabled/disabled at build time via extensions.config.ts.

Summary of Changes

Add FileActionExtension interface for menu/toolbar/both targets
Add ExtensionRegistry service for dynamic extension loading
Add extensions.config.ts for build-time configuration
Add "Copy Link" as example extension (in Share submenu)
Add "OnlyOffice" as example extension (dummy implementation)

See docs/file-extensions.md for usage.

Screenshot(s)

Example: Copy Link

extensions.config.ts:

export const extensionConfig: ExtensionConfig[] = [
  {
    load: () => import('./extensions/copy-links'),
    factory: 'copyLinksExtensionFactory',
    enabled: true,
  },
];

Copy Link (Menu Item):

Example: OnlyOffice Integration (dummy)

extensions.config.ts:

export const extensionConfig: ExtensionConfig[] = [
  // ... other extensions ...

  // Edit by OnlyOffice
  {
    load: () => import('./extensions/onlyoffice'),
    factory: 'editByOnlyOfficeExtensionFactory',
    enabled: true,
    config: { editorUrl: 'https://...' },
  },
  // Create File
  {
    load: () => import('./extensions/onlyoffice'),
    factory: 'createFileExtensionFactory',
    enabled: true,
    config: { editorUrl: 'https://...' },
  },
];

Edit by OnlyOffice(Menu Item/Toolbar Item in the file detail):

screenshot-edit-with-onlyoffice-in-detail

Create File (Toolbar Item in the file list):

Side Effects

New prebuild, prestart, pretest npm scripts that generate extensions.config.ts
src/app/extensions.config.ts is now git-ignored (generated from extensions.config.default.ts)

QA Notes

Test file context menu on file list and file detail pages
Verify "Copy Link" appears in Share submenu for files
Verify extensions can be enabled/disabled via extensions.config.ts

- Add FileActionExtension for menu/toolbar/both targets - Add ExtensionRegistry service for dynamic extension loading - Add extensions.config.ts for configuration - Add Copy Link as example extension - Add OnlyOffice as example extension (dummy implementation) See docs/file-extensions.md for usage.

Overall, the extension system appears well-designed. I reviewed it as I would a standard PR to ensure everything is in order and to identify any potential issues. I have added some questions and suggestions for consideration. Additionally, I am wondering about translations: are they required in this case?

src/app/core/provider/extension.initialization.provider.ts

+async function loadExtension(extConfig: ExtensionConfig, registry: ExtensionRegistry): Promise<void> {
+  const module = await extConfig.load();
+  const factory = (module as Record<string, FactoryFunction>)[extConfig.factory];
+
+  if (typeof factory !== 'function') {
+    throw new Error(`Extension factory "${extConfig.factory}" not found in module`);
+  }
+
+  const extensions = factory(extConfig.config);
+  registry.register(extensions);
+}


It’s better to add error handling here to be safe.

src/app/core/provider/extension.initialization.provider.ts

+export const EXTENSION_INITIALIZATION_PROVIDER: Provider = {
+  provide: APP_INITIALIZER,
+  useFactory: (registry: ExtensionRegistry) => {
+    return () => loadExtensions(registry);
+  },
+  deps: [ExtensionRegistry],
+  multi: true,
+};


APP_INITIALIZER is deprecated in favor of theprovideAppInitializer function. Use export const EXTENSION_INITIALIZATION_PROVIDER = provideExtensionInitialization();.

src/app/core/provider/extension.initialization.provider.ts

+  for (const ext of extensionConfig) {
+    if (!ext.enabled) continue;
+    await loadExtension(ext, registry);
+  }


I think it is better to use parallel loading with Promise.all or Promise.allSettled.

src/app/shared/components/file-menu/file-menu.component.ts


+  private actionContext = computed((): FileActionContext => {
+    const file = this.file();
+    if (!file) throw new Error('file is required for actionContext');


We need to add a translation key here.

src/app/shared/components/file-menu/file-menu.component.html

+        [class.p-disabled]="item.disabled"
+        [attr.aria-disabled]="item.disabled ?? false"


Why do we need it? PrimeNG's TieredMenu should handle disabled items automatically.

src/app/features/files/pages/file-detail/file-detail.component.ts


+  protected actionContext = computed((): FileActionContext => {
+    const file = this.file();
+    if (!file) throw new Error('file is required for actionContext');


Need translation key.

    () => this.isButtonDisabled() || (this.googleFilePickerComponent()?.isGFPDisabled() ?? false)
  );

+  protected actionContext = computed((): FileActionContext => {


Suggested change

protected actionContext = computed((): FileActionContext => {

actionContext = computed((): FileActionContext => {

+  protected actionContext = computed((): FileActionContext => {
+    const folder = this.currentFolder();
+    if (!folder) throw new Error('folder is required for actionContext');


Add translation key.

src/app/features/files/pages/files/files.component.ts

+    const extensions = this.extensionRegistry
+      .extensions()
+      .filter((ext) => !ext.parentId)
+      .filter((ext) => !ext.visible || ext.visible(ctx));


Can we use only 1 filter?

nsemets · 2026-01-12T12:15:46Z

src/app/features/files/pages/files/files.extensions.spec.ts

Why do we need it as separate file? Also, need improvements.

+    {
+      id: 'copy-link',
+      label: 'Copy Link',


This should be a translatable string.
