Walkthrough

The pull request replaces a static contest type in the TaskTable component with a reactive store-based approach. The component now imports and uses activeContestTypeStore to retrieve, update, and compare the active contest type via its get(), set(), and isSame() methods. A new store file has been added to manage this logic, and corresponding unit tests have been introduced. This change updates the button’s click handler and class binding to leverage the store, ensuring the contest-specific table button state is maintained reactively.

I'm a rabbit hopping with delight,
New reactive states shine so bright,
No more static, only dynamic flow,
Our buttons now gleam with a vibrant glow,
With each click, our code takes flight! 🥕🐇

1-46: Well-structured store with clear documentation.

The implementation of the ActiveContestTypeStore is clean and well-documented. The JSDoc comments provide good context about the purpose and behavior of each method.

One potential enhancement to consider in the future would be making the default value configurable through a constructor parameter, which could increase flexibility if needed elsewhere in the application.

export class ActiveContestTypeStore {
-  value = $state<ContestTableProviders>('abcLatest20Rounds');
+  value: ContestTableProviders;
+
+  constructor(defaultValue: ContestTableProviders = 'abcLatest20Rounds') {
+    this.value = $state<ContestTableProviders>(defaultValue);
+  }

19-19: Good addition of the store import.

Adding the store import is a good start to implementing a more centralized state management approach.


35-35: Good refactoring to use derived store value.

Replacing the static assignment with a derived value from the store is a good practice. This ensures the component stays reactive to changes in the active contest type across the application.


116-119: Well-implemented store-based state management.

Using the store's methods for handling clicks and determining the active button state is a good approach. This centralizes state management and helps maintain consistency across components.

src/test/lib/stores/active_contest_type.svelte.test.ts (1)

1-50: Comprehensive test coverage for the store.

The tests are well-structured and provide thorough coverage of the store's functionality. Good job using the beforeEach hook to ensure each test starts with a fresh instance of the store.

The tests properly verify:

  1. Default initialization
  2. Getting the current value
  3. Setting new values
  4. Comparing values with the isSame method

All the test cases are meaningful and help ensure the store behaves as expected in various scenarios.

1-55: Strong implementation of a reactive store for contest type!

The implementation is clean, well-documented, and follows good practices for a Svelte state store. The class provides all necessary functionality with clear method names and proper TypeScript typing.

A few minor suggestions to consider:

  1. The store uses Svelte's new $state syntax, which suggests you're working with Svelte 5 (currently in preview). Make sure your team is aware of potential API changes as Svelte 5 evolves.

  2. For more robust validation, consider adding validation in the set method to ensure the provided value is a valid contest type.

  3. You might want to add a reset() method that restores the default value, which could be useful in certain scenarios like user cancellations or application resets.

17-23: Consider encapsulation for the value property.

While the test is correct, it directly modifies the value property. Consider making this property private in the actual implementation to ensure state changes go through the setter method, which would better enforce encapsulation and potentially add validation.


21-21: Consider removing type assertion if possible.

The frequent use of as ContestTableProviders type assertions suggests the type system could be improved. Consider using string literal types or enum values that TypeScript can automatically infer without assertions.


1-67: Consider adding tests for constructor parameter.

The implementation shows that the constructor accepts a default contest type parameter, but there are no tests verifying this functionality. Consider adding a test that creates a store with a non-default initial value.

test('expects to initialize with provided value', () => {
  const customStore = new ActiveContestTypeStore('abc319Onwards' as ContestTableProviders);
  expect(customStore.get()).toBe('abc319Onwards');
});

1-11: Good test setup with proper structure and initialization.

The test file correctly imports necessary testing utilities and implements a clean setup pattern with beforeEach to ensure each test runs with a fresh store instance. This is a good practice for maintaining test isolation.


13-15: Test for default initialization looks good.

This test correctly verifies that the store initializes with the expected default value of 'abcLatest20Rounds'.


25-33: Good test coverage for the set() method.

The test thoroughly checks that the set() method correctly updates both the internal value and what's returned by get(). Testing with multiple values ensures consistency.


35-49: Comprehensive test for the isSame() method.

This test thoroughly verifies the isSame() method across multiple states and values, including both positive and negative cases. The structure with multiple assertion blocks is clear and effective.


51-66: Well-structured test for the reset() method.

The test for the reset() method is thorough and includes good comments explaining each step. It verifies the method works consistently from different starting values.
