📝 Walkthrough

Walkthrough

This PR replaces the abandoned ng5-slider library with the maintained fork @angular-slider/ngx-slider across two refinement components. Dependencies are updated to add the new slider package and upgrade date-fns from v2 to v3, with ng5-slider and moment.js removed from the manifest. Both age and range refinement components migrate their module imports, TypeScript imports, and template elements while preserving all existing data bindings and event handlers.

Old sliders fade as ngx takes the stage,
Date-fns v3 starts a fresh new page.
Two components dance with the same old sway—
Just different names for a brighter day! 🎚️

53-53: ⚠️ Potential issue | 🟠 Major | 🏗️ Heavy lift

angular-instantsearch dependency was not removed as claimed in PR objectives.

The package remains listed in package.json at line 53 and continues to be actively imported across the codebase. Confirmed usage in 25+ module files, 10+ component files, and multiple HTML templates with ais-* components. Examples: NgAisModule imports in age-refinement-list.module.ts, is-search-box.module.ts, range-refinement-list.module.ts, and many others; BaseWidget, NgAisIndex, NgAisInstantSearch imports from 'angular-instantsearch' in component files; HTML templates using <ais-instantsearch>, <ais-infinite-hits>, <ais-pagination> elements.

This represents an incomplete migration that contradicts the PR summary claim of removing angular-instantsearch imports and replacing the library with instantsearch.js.

InstantSearch widgets or your new components), ensuring tests/builds compile and
no remaining imports/usages of 'angular-instantsearch' remain.

🧩 Analysis chain

🌐 Web query:

Is @angular-slider/ngx-slider version 2.0.3 compatible with Angular 15?

💡 Result:

No, @angular-slider/ngx-slider version 2.0.3 is not compatible with Angular 15 [1][2][3]. Version 2.0.3 of @angular-slider/ngx-slider was released in February 2022 and was designed to support Angular versions 6 through 12 [1][2][3]. It does not include support for Angular 15 [1][2][3]. If you are using Angular 15, you should use a version of the package that explicitly supports it, such as version 15.x.x of the @angular-slider/ngx-slider package [1][2][3]. Alternatively, many developers facing compatibility issues with the original package have migrated to the community-maintained package ngx-slider-v2, which provides specific versions for Angular 15 [4][5].

Citations:


Upgrade @angular-slider/ngx-slider to a version compatible with Angular 15.

@angular-slider/ngx-slider v2.0.3 only supports Angular 6–12 and is incompatible with Angular 15. Use version 15.x.x or later of the package, or migrate to ngx-slider-v2 if needed.
