text-mask is a JavaScript library for enforcing consistent text formats and dynamic masking patterns in web input fields. It provides a suite of utilities to constrain text field entries to predefined masks and validators, ensuring data consistency across multiple frontend frameworks including React, Angular, and Vue.
The library supports dynamic pattern generation using functions to handle variable data formats and localized patterns. It includes capabilities for processing bulk text entries, such as pasted content and browser auto-fill data, while maintaining the integrity of the defined input mask.
The system manages frontend data formatting through input pattern enforcement and form validation. It also provides visual guidance by displaying placeholder characters and mask structures as the user types.
