This commit applies `strictNullChecks` to the entire codebase to improve
maintainability and type safety. Key changes include:
- Remove some explicit null-checks where unnecessary.
- Add necessary null-checks.
- Refactor static factory functions for a more functional approach.
- Improve some test names and contexts for better debugging.
- Add unit tests for any additional logic introduced.
- Refactor `createPositionFromRegexFullMatch` to its own function as the
logic is reused.
- Prefer `find` prefix on functions that may return `undefined` and
`get` prefix for those that always return a value.
This commit introduces `useUserSelectionState` compositional hook. it
centralizes and allows reusing the logic for tracking and mutation user
selection state across the application.
The change aims to increase code reusability, simplify the code, improve
testability, and adhere to the single responsibility principle. It makes
the code more reliable against race conditions and removes the need for
tracking deep changes.
Other supporting changes:
- Introduce `CardStateIndicator` component for displaying the card state
indicator icon, improving the testability and separation of concerns.
- Refactor `SelectionTypeHandler` to use functional code with more clear
interfaces to simplify the code. It reduces complexity, increases
maintainability and increase readability by explicitly separating
mutating functions.
- Add new unit tests and extend improving ones to cover the new logic
introduced in this commit. Remove the need to mount a wrapper
component to simplify and optimize some tests, using parameter
injection to inject dependencies intead.
This commit simplifies event handling, providing a unified and robust
way to handle event lifecycling. This way, it fixes events not being
unsubscribed when state is changed.
Introduce a new function in `EventSubscriptionCollection` to remove
existing events and adding new events. This provides an easier to use
API, which leads to code that's easier to understand. It also prevents
potential bugs that may occur due to forgetting to call both functions.
It fixes `TheScriptsMenu` not unregistering events on state change.
Other improvements include:
- Include a getter to get total amount of registered subcriptions.
This helps in unit testing.
- Have nullish checks to prevent potential errors further down the
execution.
- Use array instead of rest parameters to increase readability and
simplify tests.
Ensure `SliderHandler` stops resizes on unmount, unsubscribing from all
events and resetting state to default.
Update `injectionKeys` to do imports as types to avoid circular
dependencies. Simplify importing `injectionKeys` to enable and strict
typings for iterating injection keys.
Add tests covering new behavior.
- Fix a bug (introduced in 1b9be8fe) preventing the tree view from being
visible during a search.
- Fix a minor bug where the scripts view does not render based on the
initial filter.
- Add Vue component tests for `TheScriptView` to prevent regressions.
- Refactor `isSearching` in `TheScriptView` to simplify its logic.
- Use function abstractions (such as map, reduce, filter etc.) over
for-of loops to gain benefits of having less side effects and easier
readability.
- Enable `downLevelIterations` for writing modern code with lazy evaluation.
- Refactor for of loops to named abstractions to clearly express their
intentions without needing to analyse the loop itself.
- Add missing cases for changes that had no tests.
Major refactoring using ESLint with rules from AirBnb and Vue.
Enable most of the ESLint rules and do necessary linting in the code.
Also add more information for rules that are disabled to describe what
they are and why they are disabled.
Allow logging (`console.log`) in test files, and in development mode
(e.g. when working with `npm run serve`), but disable it when
environment is production (as pre-configured by Vue). Also add flag
(`--mode production`) in `lint:eslint` command so production linting is
executed earlier in lifecycle.
Disable rules that requires a separate work. Such as ESLint rules that
are broken in TypeScript: no-useless-constructor (eslint/eslint#14118)
and no-shadow (eslint/eslint#13014).
