ngx-scrollbar
Custom overlay scrollbars with native scrolling mechanism and smooth scrolling for Angular applications.
What is ngx-scrollbar?
ngx-scrollbar is an Angular library that provides customizable overlay scrollbars with native scrolling performance. It solves the problem of inconsistent and unstylable browser scrollbars by offering a fully customizable scrollbar component that maintains the browser's native scrolling mechanism for optimal performance.
Angular developers building applications that require customized scrollbar styling, smooth scrolling functionality, or integration with complex UI components like data tables, virtual scroll lists, and dropdowns.
Developers choose ngx-scrollbar because it delivers exceptional performance through native scrolling, offers extensive customization via CSS variables, and provides seamless integration with Angular Material, CDK Virtual Scroll, and popular third-party UI libraries.
Overview
Custom overlay-scrollbars with native scrolling mechanism
Use Cases
Best For
- Replacing default browser scrollbars with custom-styled overlay scrollbars in Angular applications
- Implementing smooth scrolling functionality across different browsers in Angular projects
- Integrating custom scrollbars with Angular Material components like MatSelect and dialogs
- Adding scrollbar customization to virtual scrolling implementations using Angular CDK
- Styling scrollbars in data-heavy applications using tables from ag-Grid, PrimeNG, or ngx-datatable
- Building Angular applications that require RTL support or mobile-optimized scrolling experiences
Not Ideal For
- Non-Angular projects using frameworks like React or Vue
- Applications where native CSS scrollbar properties (e.g., ::-webkit-scrollbar) fully meet styling needs
- Projects with strict bundle size constraints that cannot afford additional JavaScript dependencies
Pros & Cons
Pros
Leverages the browser's native scroll engine for smooth, efficient scrolling, with performance tests validating its exceptional speed and responsiveness.
Uses CSS variables for easy scrollbar styling, enabling consistent theming across Angular applications without complex JavaScript overrides.
Seamlessly integrates with Angular Material (e.g., MatSelect), CDK Virtual Scroll, and third-party libraries like PrimeNG and ag-Grid, as documented with extensive examples.
Provides a directive that polyfills smooth scrolling functionality across all modern browsers, addressing compatibility gaps where native CSS support is lacking.
Cons
Exclusively tied to the Angular framework, making it useless for projects built with React, Vue, or other frontend technologies.
Adds to the overall JavaScript bundle, which could slow initial load times for performance-sensitive applications, despite its native scrolling optimizations.
Documentation is split across multiple markdown files (e.g., Usage.md, Styling.md), which can make it harder to find specific information quickly compared to a unified guide.
