Blaze Slider

⚡️ blaze-slider.dev

Blaze slider is a high-performance JavaScript UI library for creating sliders.

The Problem

Existing slider libraries are not designed with performance in mind. They block the main thread for a long time when initializing a slider which results in poor UX and poor FID metric for your website.

They also create layout shifts that negatively impact the UX and CLS metric of your website. These libraries don't provide any idiomatic way to reduce the layout shifts.

The Solution

Blaze slider is built to fix these issues. It can initialize the slider incredibly fast. It initializes the slider 30x faster than the Slick slider, and 15x faster than the Swiper slider.

Blaze Slider allows you to specify the layout configuration via CSS variables which enable slider initialization with zero layout shifts! - so that your slider will look exactly the same before and after javascript runs.

Benchmark

| Rank | Library | Time | Speed | Layout Shift Fixable? | | ---- | --------- | ------- | ------------------ | --------------------- | | 1 | Blaze ⚡️ | 1.4ms | 1x | Yes | | 2 | Keen | 6.3ms | 4.5x slower | Yes - Manually* | | 3 | Embla | 7.5ms | 5.3x slower | Yes - Manually* | | 4 | Glide | 10.0ms | 7.14x slower | Yes - Manually* | | 5 | Flickity | 12.3ms | 8.78x slower | Yes - Manually* | | 6 | Swiper | 28.3ms | 20.2x slower | Yes - Manually* | | 7 | Slick | 49.29ms | 35.2x slower | Yes - Manually* |

Manually* means that the slider library itself does not provide an idiomatic way to fix the layout shift. You have to manually add CSS to fix the layout shifts

Benchmark measures the time taken to create a slider with 10 slides by each slider. Benchmark is measured on Apple M1 Pro CPU with 6X slowdown on Google Chrome 103. The Average of 20 runs is taken.
