@mnrx/svelte-store

This is a re-implementation of svelte/store which offers more accurate tracking of derived store validity, ensuring that re-evaluations do not happen on invalid upstream state. It also includes expanded TypeScript support and a small addition to the public API of get().

For more information, see the pull request to Svelte.

Testing

To test this implementation against Svelte 5's test suite, run the following commands, starting in this file's directory:

git clone --depth=1 https://github.com/sveltejs/svelte.git
cd svelte
pnpm install
npx playwright install
cp ../src/main.ts packages/svelte/src/store/
echo "export { writable, readable, derived, readonly, get, get_store_value } from './main.ts';" \
  > packages/svelte/src/store/index.js
pnpm run test

To test the TypeScript type definitions, see test/test.ts.
