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.
Key highlights:
- Written from scratch to cater specifically to privacy.sexy's
needs and requirements.
- The visual look mimics the previous component with minimal changes,
but its internal code is completely rewritten.
- Lays groundwork for future functionalities like the "expand all"
button a flat view mode as discussed in #158.
- Facilitates the transition to Vue 3 by omitting the Vue 2.0 dependent
`liquour-tree` as part of #230.
Improvements and features:
- Caching for quicker node queries.
- Gradual rendering of nodes that introduces a noticable boost in
performance, particularly during search/filtering.
- `TreeView` solely governs the check states of branch nodes.
Changes:
- Keyboard interactions now alter the background color to highlight the
focused item. Previously, it was changing the color of the text.
- Better state management with clear separation of concerns:
- `TreeView` exclusively manages indeterminate states.
- `TreeView` solely governs the check states of branch nodes.
- Introduce transaction pattern to update state in batches to minimize
amount of events handled.
- Improve keyboard focus, style background instead of foreground. Use
hover/touch color on keyboard focus.
- `SelectableTree` has been removed. Instead, `TreeView` is now directly
integrated with `ScriptsTree`.
- `ScriptsTree` has been refactored to incorporate hooks for clearer
code and separation of duties.
- Adopt Vue-idiomatic bindings instead of keeping a reference of the
tree component.
- Simplify and change filter event management.
- Abandon global styles in favor of class-scoped styles.
- Use global mixins with descriptive names to clarify indended
functionality.
