This commit resolves a rendering bug in the tree view component.
Previously, updating the tree collection prior to node updates led to
rendering errors due to the presence of non-existent nodes in the new
collection.
Changes:
- Implement manual control over the rendering process in tree view. This
includes clearing the rendering queue and currently rendered nodes
before updates, aligning the rendering process with the updated
collection.
- Add Cypress E2E tests to test switching between all operating systems
and script views, ensuring no uncaught errors and preventing
regression.
- Replace hardcoded operating system lists in the download URL list view
with a unified `getSupportedOsList()` method from the application,
reducing duplication and simplifying future updates.
- Rename `initial-nodes` to `nodes` in `TreeView.vue` to reflect their
mutable nature.
- Centralize the function for getting operating system names into
`OperatingSystemNames.ts`, improving reusability in E2E tests.
This commit changes `WatchSource` signatures into `Readonly<Ref>`s.
It provides two important benefits:
1. Eliminates the possibility of `undefined` states, that's result of
using `WatchSource`s. This previously required additional null checks.
By using `Readonly<Ref>`, the state handling becomes simpler and less
susceptible to null errors.
2. Optimizes performance by using references:
- Avoids the reactive layer of `computed` references when not needed.
- The `watch` syntax, such as `watch(() => ref.value)`, can introduce
side effects. For example, it does not account for `triggerRef` in
scenarios where the value remains unchanged, preventing the watcher
from running (vuejs/core#9579).
Optimize the tree view rendering during searches by enhancing the render
queue ordering. This update changes the rendering order to prioritize
visible nodes, leading to faster appearance of these nodes during
searches. The ordering logic now ignores the depth in the hierarchy and
instead focused on the node order. The collapsed check for the node
itself is removed, ensuring that visible collapsed parents are first
while their invisible children are rendered later.
The tree view rendering performance is optimized by improving the node
render queue ordering. The node rendering order is modified based on the
expansion state and the depth in the hierarchy, leading to faster
rendering of visible nodes. This optimization is applied when the tree
nodes are not expanded to improve the rendering speed.
This new ordering ensures that nodes are rendered more efficiently,
prioritizing nodes that are collapsed and are at a higher level in the
hierarchy.
This commit fixes an issue where the check state of categories was lost
when toggling between card and tree views. This is solved by immediately
emitting node state changes for all nodes. This ensures consistent view
transitions without any loss of node state information.
Furthermore, this commit includes added unit tests for the modified code
sections.
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.
