How do I add spoiler alert to my website?

Include the spoiler.js script, then call spoilerAlert('selector') with your CSS selectors, like spoilerAlert('.spoiler'). Customize blur with options such as {max: 10, partial: 4} for different intensity levels.

Is spoiler alert better than using CSS blur?

SPOILER ALERT! uses SVG blur for consistency across browsers and adds interactive reveal on hover and click, which CSS filter: blur() alone doesn't handle. However, for simple static blurring, CSS might be sufficient without JS overhead.

Does spoiler alert work with images?

Yes, the library applies SVG blur effects to both text and images, as mentioned in the description and demo, allowing users to reveal visual spoilers interactively.

Can I use spoiler alert with frameworks like React or Vue?

While not designed for frameworks, you can integrate it by including the script and calling the function in component lifecycle methods. For better integration, consider framework-specific libraries or custom wrappers.

How to make spoiler alert accessible for keyboard users?

The library lacks built-in keyboard support; you would need to add custom event listeners for key presses (e.g., Enter or Space) to simulate hover and click actions, which adds development overhead.

What browsers does spoiler alert support?

As per the README, it's tested in Chrome, Safari, Firefox, and Mobile Safari, so it works in most modern browsers, but always test in your specific environments for compatibility issues.

What is spoiler-alert?

SPOILER ALERT! is a JavaScript library that helps website owners hide spoiler content using SVG blur effects. It solves the problem of accidentally revealing plot points or sensitive information by blurring text and images, which users can then reveal through hover and click interactions.

Target Audience

Website owners, bloggers, and content publishers who share spoiler-prone content like movie reviews, book analyses, or game walkthroughs.

Value Proposition

Developers choose SPOILER ALERT! because it's lightweight, easy to implement, and provides an elegant visual solution to spoiler management without requiring complex CSS or framework dependencies.

Overview

SPOILER ALERT! A happy little bit of javascript to hide spoilers on your site.

Use Cases

Best For

Movie review websites that discuss plot details
Book blogs with detailed chapter analyses
Gaming sites with walkthroughs and ending explanations
TV show recaps that contain episode spoilers
Forum discussions where spoilers need to be hidden by default
Educational content with surprise answers or solutions

Not Ideal For

Websites that must function without JavaScript enabled, as the library relies entirely on client-side JS for blur effects and interactions.
Applications requiring advanced spoiler management like user preference saving, persistent reveal states, or complex animation transitions.
Projects with strict accessibility standards, where SVG blur effects may not be fully compatible with screen readers or keyboard navigation.

Pros & Cons

Pros

Easy Integration

Simply include spoiler.js and call a function with CSS selectors, as shown in the README with spoilerAlert('spoiler, .spoiler'), making setup quick with minimal code.

Adjustable Blur Intensity

Configuration options allow setting maximum and partial blur levels, demonstrated in the README with {max: 10, partial: 4}, giving control over visual hiding.

Cross-Browser Support

Tested and works in Chrome, Safari, Firefox, and Mobile Safari, ensuring broad compatibility for most modern web environments.

Visual Elegance

Uses SVG blur filters to hide content in a visually appealing way, enhancing user experience over plain text hiding or basic CSS methods.

Cons

Limited Reveal Mechanisms

Only supports mouseover and click interactions; lacks keyboard navigation, touch gestures beyond click, or other advanced user controls for accessibility.

No State Persistence

Revealed content remains visible without a way to re-hide spoilers or save user preferences across sessions, limiting usability for repeat visitors.

Basic Customization

Customization is restricted to blur levels; no options for colors, animation speed, or other stylistic elements, as admitted by the minimal configuration.
