Svelte `4.0.0`

[ibilux]

A lot of components showing errors when updated svelte to version 4.0.0.

Expanding on this - Svelte depreciated SvelteComponentTyped

The PR: sveltejs/svelte#8512

The types will need to be updated in account for this change.

Edit:
sveld will need to be updated, once that is done then the types here can be updated. Issue here

Thanks, everyone. I'm actively working to test carbon-components-svelte with Svelte 4. It requires a bit of work:

• upgrade dependencies and documentation to use ESM syntax
• add Svelte ^3.20.0 || ^4.0.0 to peerDependencies
• Update types (along with sveld)

I'll track this issue once a PR is ready.

I know you're working on fixing this, but is it possible to tell the svelte compiler to ignore these errors in the meantime?

I think you can temporary fix this issue with 2 things:

1. in tsconfig.json add skipDefaultLibCheck: true and skipLibCheck: true.
2. instance version svelte@^3 to package dependencies . npm I svelte@^3.

it can temporary disable incorrect check.

Hi everyone, do we have any updated version to support this?
When creating a new Sveltekit project, we must re-install Svelte version 3 to bypass the issue.

This library now supports Svelte 4 for TypeScript users in v0.78.0.

The type definitions are still backward compatible with Svelte version 3; however, the minimum Svelte version is now 3.55 for TypeScript users.

For TypeScript Users using Svelte 4

If you're using Svelte 4 with the icons/pictograms packages, you must upgrade them as well:

• Upgrade carbon-icons-svelte to version 12.1.0
• Upgrade carbon-pictograms-svelte to version 12.6.0
