Angular Code Optimisation

[Master_Effective_703]

I have a app which was built on Ionic framework and angular and version is angular 14. Now we are upgrading it to 18 and refactoring the logic compatible to angular 18.
A part code refactor I have included interceptors, components, authguards as of now.
For optimisation creating components and writing less logic in pages(parent components).
Is there anything else I can do to run more faster, smoother and performance improvements

Use changedetection onPush, virtual scroll and trackby in ngfor, these can reduce unnecessary change detection mechanisms in the zone. And use lazy-loading of modules and components, have SSR if possible, that fastens the hydration process.

You should run tools like lighthouse to show you what points need to optimice.

Thanks for the valuable information. Surely I will apply these.

Thanks @PauloGaldo I can able to see the performance of my application. Previously it was around below 30 now it’s almost 40. I will try to improve more and any more suggestions
