## What it is
ngx-mask is an Angular library providing a standalone directive and pipe for input masking in form fields and HTML elements. It supports custom patterns, number formatting, dates, and works with Reactive Forms, template-driven forms, and Signal Forms.

## Use cases
- mask phone number inputs in angular forms
- format currency with thousand separators in input fields
- validate date input masks in angular
- apply custom input patterns like CPF/CNPJ
- mask form fields in zoneless angular apps
- format percent and decimal inputs

## When to choose
- you are building Angular applications and need input masking
- you need masks that work with Reactive Forms, template-driven, and Signal Forms
- you want a lightweight, dependency-free masking solution with SSR and zoneless support

## When to avoid
- you are not using Angular
- you need masking for plain JavaScript or other frameworks like React or Vue
- you need fully dynamic masking logic beyond pattern-based masks
