Is a Shared Angular Material Import Recommended in 2025 with Standalone Components in Angular...

I’m working on a large-scale Angular 19 project using standalone components. In the past, with NgModules, it was common to create a SharedMaterialModule that imported all Angular Material modules (e.g. MatButtonModule, MatIconModule, MatFormFieldModule) and then imported this module into feature modules. However, with Angular 19’s standalone components, I’m unsure if a shared import approach is still recommended or if I should import Material modules separately in each component’s imports array.

Some AI-based tools (grok, chatgpt) recommend avoiding a shared Material module and instead importing only the specific Material modules needed by each standalone component (imports: [MatButtonModule, MatIconModule]). The reasoning seems to be that this approach:

• Reduces bundle size by leveraging Angular’s
• tree-shaking to exclude unused modules.
• Makes dependencies explicit, improving maintainability.

My questions:

1. In 2025, with Angular 19 and standalone components, is it still recommended to use a shared Angular Material import (e.g. a barrel file or shared array) for Material modules, or should I import modules separately in each component?
2. What are the industry practices for managing Angular Material imports in large-scale projects using standalone components? Are teams centralizing imports, using custom standalone components to encapsulate Material modules, or importing modules per component?
3. Are there performance trade-offs (e.g. bundle size, build time) between a shared import approach and per-component imports?

Thank you!!!
