DISCUSSION - Rebuilding ionic-svelte

[Tommertom]

Hey there,

Looking to rebuild ionic-svelte - I want to get rid of some of the blocking bugs with overlays, remove code that duplicates @ionic/core and make it easier to follow Svelte(Kit) and Ionic release updates.

I want to capture a few design principles for rebuilding ionic-svelte and looking to get feedback from the community:

• we should follow the ionic documentation for components as close as possible
• we wont support ionic cli commands
• in case we cannot follow the ionic documentation we create a customer solution that we document via example code
• we prefer helper functions over creating custom .svelte components (e.g. we don't want to ship Ion*.svelte) - e.g. [Question] How to implement router with IonTabs? #91 - where we like to ditch IonTabs and can simplify DX with a helper function
• we pref additional div/etc elements over creating custom .svelte components (e.g IonTabs pushes ion-footer outside the viewport #81 - where we need to add div class='ion-page' to assure ion-footers are shown correctly.
• we want to import as much as possible from @ionic/core - so we also do not re-export types and controllers from ionic-svelte
• we will support SvelteKit and non-Kit projects
• if we export functions we prefer JSDOC over Typescript
• we will not rebuild and/or create strong dependencies on the kit router to achieve native transitions

Happy to hear your thoughts on these and other design principles and the consequences for the implemention of for instance:

• dealing with nav stacks - Tabs and Subpages #86 - to remove IonTabs and support further navigation - posted by RingoRohe

Some issues I am not sure yet how to solve

• Ionic safe area on iOS - IOS notch safe area not working #92 - need repo to reproduce
• Typings on components - Improving types #88 - need to test
• Typings error with importing - Could Not Find a Declaration File for Module when Importing Special Component in Svelte File #90 - need repo to reproduce
• SwipeToGetBack behaviour - SwipeToGetBack Animation broken on IOS #85 - need to see this happening (positive and negative case)
• Showing correct Event types- Event types are not properly showing in IDE #65
• Npm create CLI commands - we need these or not?

Things I plan to remove/or do not return

• PWA stuff - service worker config and API as per Vite plugin
• No modalController and popoverControllers - these create all sorts of issues with CSS code inlines are recommended anyway

Ongoing rebuild with demo app posted on github - https://github.com/Tommertom/ionicsvelterebuild

Hi, sorry to say that but after recreating your Demo app I have strange behavior of the tabs, they just randomly appear and disappear. See the video

@keev-studio could you share a link to your repo where you're experiencing this issue, and I can take a look?

[Tommertom]

@keev-studio - can you please continue this issue under #86 or a new one, so we have this issue focus on the possible rebuild of ionic-svelte?

Perhaps it makes sense to use svelte 5 right away, so as not to migrate later?
