Implement multi-region support in RegionMap component. #190
Conversation
The function `fetchSelectedRegionGeometry` is refactored into two functions: `getRegionGeometry` and `fetchSelectedRegionGeometry`. The former is responsible for fetching the geometry of a specific region, while the latter calls the former function for the selected region. The former function is also necessary to fetch geometries of several regions. Issue: #185 Signed-off-by: Nikolay Martyanov <ohmspectator@gmail.com>
Added a TODO comment in the API for regions to return an empty array instead of null when the response status is 204 (No Content). Issue: #189 Signed-off-by: Nikolay Martyanov <ohmspectator@gmail.com>
Introduced a new function named getVisibleRegions in RegionMap component. This function fetches subregions if the selected region has subregions. If the selected region doesn't have subregions, it fetches the siblings of the selected region. It will be used to display the necessary regions.

Introduced the capability to render multiple regions simultaneously in the RegionMap component. This major enhancement includes displaying borders for each region, highlighting the selected region with a distinct color, and dynamically updating the map based on the selected region's siblings or subregions. Replaced the fetchSelectedRegionGeometry function with a more comprehensive approach within initializeMap, handling multiple features and ensuring a responsive and informative map display.

Enhanced the RegionMap component by implementing a mechanism to avoid re-rendering regions that are already rendered. This update introduces state management for tracking rendered features, coupled with a function `updateSelectedRegionStyle` that selectively updates the style of a newly selected region if it's already present in the rendered features array. This change significantly reduces the computational overhead by preventing redundant re-rendering of the map, thereby optimizing the performance and responsiveness of the map interface.

WalkthroughThe code changes focus on enhancing the map visualization in a frontend application. They involve updating the logic for fetching and displaying region geometries, initializing the map with new features, and ensuring that the map's display of regions adapts dynamically to user interactions. Specifically, the updates allow for the display of all regions at the current level, with distinct visual styles to differentiate them from other map elements. Changes

5-5: The import statement has been updated to include
fetchSiblingsandfetchSubregions. This aligns with the PR objectives to enhance multi-region rendering capabilities.21-21: The addition of
renderedFeaturesstate is part of the performance optimization to manage the features rendered on the map. Verify that the state is updated appropriately throughout the component lifecycle.62-80: The
getVisibleRegionsfunction fetches either subregions or siblings based on the selected region. Ensure that the error handling is consistent and that the function returns the expected data structure in all cases.82-102: The
updateSelectedRegionStylefunction updates the style of the selected region. Verify that the map source update and bounds fitting are handled correctly and efficiently.59-155: > Note: This review was outside the patches, so it was mapped to the patch with the greatest overlap. Original lines [104-197]
The
initializeMapfunction is responsible for initializing the map with the visible regions. Ensure that the map initialization and feature rendering logic are optimized and that error handling is robust.
- 199-208: The
useEffecthook has been updated to handle map initialization and style updates. Verify that the dependency array is correct and that the logic within the hook does not introduce unnecessary re-renders.
Description
This Pull Request introduces a series of enhancements to the RegionMap component aimed at improving its performance and functionality. Notably, it includes the ability to render multiple regions simultaneously, optimize rendering processes to prevent unnecessary re-rendering, and refine the mechanism for fetching and displaying region geometries.
