Added intelligent watchlist refresh mechanism that only refetches data when changes are actually made, preventing unnecessary API calls and improving performance. Changes: - Added watchlistNeedsRefresh store to track when watchlist data has changed - Implemented reactive watcher in App.svelte that uses svelte-spa-router's loc store to detect navigation to home - Set dirty flag in Anime.svelte after successful status updates and entry deletions - Added conditional refresh logic that checks user's primary service (AniList, MAL, or Simkl) - Parallel refresh support for multiple services when logged in This resolves the issue where clicking the logo would cause full page reloads and unnecessary re-authentication checks, while also ensuring watchlist data stays current when users make changes. Technical details: - Uses $loc.location to detect route changes - IIFE pattern for async operations in reactive statements - Only refreshes for logged-in primary services - Flag resets after successful refresh Related to: Header.svelte client-side routing fix
Svelte + TS + Vite
This template should help get you started developing with Svelte and TypeScript in Vite.
Recommended IDE Setup
Need an official Svelte framework?
Check out SvelteKit, which is also powered by Vite. Deploy anywhere with its serverless-first approach and adapt to various platforms, with out of the box support for TypeScript, SCSS, and Less, and easily-added support for mdsvex, GraphQL, PostCSS, Tailwind CSS, and more.
Technical considerations
Why use this over SvelteKit?
- It brings its own routing solution which might not be preferable for some users.
- It is first and foremost a framework that just happens to use Vite under the hood, not a Vite app.
vite devandvite buildwouldn't work in a SvelteKit environment, for example.
This template contains as little as possible to get started with Vite + TypeScript + Svelte, while taking into account
the developer experience with regards to HMR and intellisense. It demonstrates capabilities on par with the
other create-vite templates and is a good starting point for beginners dipping their toes into a Vite + Svelte
project.
Should you later need the extended capabilities and extensibility provided by SvelteKit, the template has been structured similarly to SvelteKit so that it is easy to migrate.
Why global.d.ts instead of compilerOptions.types inside jsconfig.json or tsconfig.json?
Setting compilerOptions.types shuts out all other types not explicitly listed in the configuration. Using triple-slash
references keeps the default TypeScript setting of accepting type information from the entire workspace, while also
adding svelte and vite/client type information.
Why include .vscode/extensions.json?
Other templates indirectly recommend extensions via the README, but this file allows VS Code to prompt the user to install the recommended extension upon opening the project.
Why enable allowJs in the TS template?
While allowJs: false would indeed prevent the use of .js files in the project, it does not prevent the use of
JavaScript syntax in .svelte files. In addition, it would force checkJs: false, bringing the worst of both worlds:
not being able to guarantee the entire codebase is TypeScript, and also having worse typechecking for the existing
JavaScript. In addition, there are valid use cases in which a mixed codebase may be relevant.
Why is HMR not preserving my local component state?
HMR state preservation comes with a number of gotchas! It has been disabled by default in both svelte-hmr
and @sveltejs/vite-plugin-svelte due to its often surprising behavior. You can read the
details here.
If you have state that's important to retain within a component, consider creating an external store which would not be replaced by HMR.
// store.ts
// An extremely simple external store
import { writable } from 'svelte/store'
export default writable(0)
