How do I customize the look of angular-code-input with CSS?

Use the provided CSS variables like --item-spacing and --item-border to adjust spacing, borders, and colors globally or per component. The README includes a detailed table with examples, such as setting bottom-only borders for a minimalist design.

Does angular-code-input work with Ionic for mobile apps?

Yes, it's explicitly supported for Ionic 4-7+ and tested on iOS and Android, making it suitable for hybrid mobile apps. The component integrates seamlessly with Ionic's Angular base without additional setup.

Angular-code-input vs ng-otp-input: which is better for OTP fields?

Angular-code-input excels with broader Angular/Ionic support and CSS customization via variables, while ng-otp-input might offer different event handling. Choose angular-code-input if you need clipboard paste and deep styling control; compare based on your framework version and design requirements.

How to handle clipboard paste events in angular-code-input?

The component automatically supports paste events: users can paste a code from clipboard, and it will populate the fields accordingly. No extra code is needed, as mentioned in the key features for faster entry.

Is angular-code-input accessible for screen readers?

It includes accessibility options like autocapitalize attributes and focus control, but the README doesn't detail ARIA labels or thorough screen reader testing. You may need to add additional attributes for full compliance.

How to reset the code input programmatically in Angular?

Use the reset() method by accessing the component via @ViewChild, as shown in the README. This clears values or resets to a predefined code, with optional change emission for validation updates.

What is angular-code-input?

Angular Code Input is a reusable Angular component for entering verification codes, PINs, OTPs, and passwords in web and mobile applications. It solves the need for a customizable, accessible, and robust input field that handles multi-digit codes with events for validation and completion.

Target Audience

Angular and Ionic developers building authentication flows, verification screens, or any feature requiring numeric or alphanumeric code input in web or mobile apps.

Value Proposition

Developers choose Angular Code Input for its extensive customization via CSS variables, support for clipboard events, and seamless integration with Angular and Ionic frameworks, eliminating the need to build such components from scratch.

Overview

Code (number/chars/otp/password) input component for angular 7, 8, 9, 10, 11, 12+ projects including Ionic 4, 5 +

Use Cases

Best For

Adding OTP verification fields to Angular login forms
Building PIN entry screens for Ionic mobile apps
Creating customizable password input with hidden characters
Implementing multi-digit code validation with real-time feedback
Developing authentication flows that require clipboard paste support
Styling code input fields to match design systems with CSS variables

Not Ideal For

Projects using React, Vue, or other non-Angular frameworks where framework dependencies are a constraint
Applications requiring server-side rendered input fields with zero JavaScript for performance or SEO reasons
Teams that need out-of-the-box, pre-styled components without any CSS customization effort
Environments targeting older browsers like Edge v.41-44 where the code hidden feature is unsupported

Pros & Cons

Pros

Broad Framework Compatibility

Supports Angular 7-16+ and Ionic 4-7+, as stated in the README, making it versatile for web and mobile hybrid apps across iOS, Android, and desktop browsers.

CSS Customization Flexibility

Offers extensive CSS variable control for borders, spacing, colors, and focus states, allowing deep visual integration into design systems without overriding styles.

Clipboard Integration

Includes paste event support for faster code entry from the clipboard, a key feature highlighted in the description that enhances user experience in authentication flows.

Event-Driven Validation

Emits codeChanged and codeCompleted events for real-time feedback and submission handling, crucial for building responsive verification screens without manual logic.

Cons

Angular Version Lock-in

Requires version-specific installations (e.g., 2.x+ for Angular 16+, 1.x+ for 7-15), which complicates upgrades and limits use outside Angular's ecosystem.

CSS Complexity for Styling

Customization relies heavily on CSS variables and mentions deprecated ::ng-deep selectors, adding a learning curve and potential maintenance issues for teams less familiar with advanced CSS.

Limited Older Browser Support

The README admits that Edge v.41-44 lacks the code hidden feature, meaning inconsistent user experiences in legacy environments without fallbacks.
