Why scroll lock?

The idea of this component is make the process of locking the page scroll transparent and easier. So the main point is integrate this component with other tooling process, such as:

  • When open a modal component
  • Open a hamburguer menu
  • Any other that you like :)

It's totally transparent for you and you can integrate easier in your application, improving your user experience 🎉


Try out our demo on Stackblitz!


You can get it on NPM installing ngx-scroll-lock module as a project dependency.

npm install ngx-scroll-lock --save


You'll need to add NgxScrollLockModule to your application module. So that, the <ngx-scroll-lock> components will be accessible in your application.

import { NgxScrollLockModule } from 'ngx-scroll-lock';
  declarations: [
  imports: [
  providers: [],
  bootstrap: [YourAppComponent]

export class YourAppComponent {}

After that, you can use the ngx-scroll-lock component in your templates, passing the target element into the component itself and/or .

  • target: DOM element to be locked. Default: document.body;
  • lock: Boolean to be changed in case a scroll lock is needed from outside ngx-scroll-lock component;
import { Component } from "@angular/core";

  selector: "my-app",
  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.css"],
export class AppComponent {
  lock = false;
  target = "#my-element-with-scroll";
<ngx-scroll-lock [lock]="lock" [target]="target"></ngx-scroll-lock>
<div id="my-element-with-scroll"></div>

Please make sure you have the target element available when using it.
