elements-angular: Evaluate standalone mode

[janivo]

Description

Angular now offers a standalone components approach as an alternative to the NgModule approach. Evaluate the feasibility and benefits of transitioning our Angular components to this new standalone format.

Key Considerations:

• Assess the advantages of adopting standalone components in terms of development workflow, maintainability, and potential performance improvements.
• Evaluate how the standalone components approach enhances the experience for consumers of our Angular components. Consider factors such as ease of integration, reduced dependencies, and improved flexibility.
• Investigate whether Stencil, our component compiler, provides a seamless way to export components as standalone
• Will our current InoElementsConfig still work with this new approach?

Acceptance Criteria

• Provide a comprehensive report summarizing the benefits and drawbacks of adopting standalone components in Angular.
• Formulate a clear recommendation on whether to transition to standalone components based on the evaluation.
• If recommended, outline the steps and considerations for implementing standalone components. This should include any necessary updates to our Angular and Stencil configurations.

Evaluation of providing standalone mode for Angular

• Stencil provides an export mode for standalone components
  • requires additional output target: dist-custom-elements
• InoElementsConfig is supported but needs an extra provider export
• Required a copy of all @Directive to set the standalone property
  • To reduce code duplications we can add a mew layer for shared code
• The behavior of assets loading like icons changed
  • assets not copied to output automatically
  • assets loaded dynamically via assets path
  • might be a problem when integrate it

Beside this. when we provide this new approach following things we have to update:

• Our integration guide
• Add a migration guide to standalone mode
  • Mostly we can adapt from Ionic Framework
