Migration Guides

Flickity

Migrate from Flickity to Blossom Carousel by replacing Flickity cells, options, and events with native scrolling and CSS.

Flickity creates a carousel from cell elements, option objects, generated controls, selected-cell state, and a JavaScript instance.

Blossom keeps the carousel as a native scroll container. Layout, slide sizing, cell alignment, spacing, and responsive behavior belong in CSS, while Blossom adds dragging and small convenience methods.

Migration mindset

When moving from Flickity to Blossom, migrate the carousel in three steps:

Replace Flickity initialization with a single <BlossomCarousel> root and direct children.
Move Flickity options such as cellAlign, contain, wrapAround, and groupCells into CSS or native scrolling.
Replace Flickity methods and events with Blossom methods, native scroll APIs, and browser observers.

Flickity migrations work best when you treat each cell as a normal scroll-snap child instead of a measured item in a carousel engine.

Installation

Remove Flickity and install the matching Blossom package for your framework.

npm uninstall vue-flickity flickity
npm install @blossom-carousel/vue

npm uninstall react-flickity-component flickity
npm install @blossom-carousel/react

npm uninstall flickity
npm install @blossom-carousel/svelte

npm uninstall flickity
npm install @blossom-carousel/core

Import Blossom's core stylesheet once in your app.

import "@blossom-carousel/core/style.css";

Component structure

Flickity initializes behavior on an element and treats its children as cells. Blossom keeps that direct-child model, but the root itself is the native scroll container.

<script setup lang="ts">
import Flickity from "vue-flickity";import "flickity/css/flickity.css";import { BlossomCarousel } from "@blossom-carousel/vue";import "@blossom-carousel/core/style.css";</script>

<template>
  <Flickity :options="{ cellAlign: "left", contain: true }">    <div class="carousel-cell">Slide 1</div>    <div class="carousel-cell">Slide 2</div>    <div class="carousel-cell">Slide 3</div>  </Flickity>  <BlossomCarousel class="carousel grid! grid-auto-cols grid-cols-[calc((100% - 3rem) / 4)] gap-4">    <div class="slide snap-start">Slide 1</div>    <div class="slide snap-start">Slide 2</div>    <div class="slide snap-start">Slide 3</div>  </BlossomCarousel></template>

import Flickity from "react-flickity-component";import "flickity/css/flickity.css";import { BlossomCarousel } from "@blossom-carousel/react";import "@blossom-carousel/core/style.css";
export function Carousel() {
  return (
    <Flickity options={{ cellAlign: "left", contain: true }}>      <div className="carousel-cell">Slide 1</div>      <div className="carousel-cell">Slide 2</div>      <div className="carousel-cell">Slide 3</div>    </Flickity>    <BlossomCarousel className="carousel grid! grid-auto-cols grid-cols-[calc((100% - 3rem) / 4)] gap-4">      <div className="slide snap-start">Slide 1</div>      <div className="slide snap-start">Slide 2</div>      <div className="slide snap-start">Slide 3</div>    </BlossomCarousel>  );
}

<script>
  import { onMount } from "svelte";  import Flickity from "flickity";  import "flickity/css/flickity.css";  import BlossomCarousel from "@blossom-carousel/svelte";  import "@blossom-carousel/core/style.css";
  let carousel;
  onMount(() => {    const flickity = new Flickity(carousel, { cellAlign: "left", contain: true });    return () => flickity.destroy();  });</script>

<div class="carousel" bind:this={carousel}>  <div class="carousel-cell">Slide 1</div>  <div class="carousel-cell">Slide 2</div>  <div class="carousel-cell">Slide 3</div></div><BlossomCarousel class="carousel grid! grid-auto-cols grid-cols-[calc((100% - 3rem) / 4)] gap-4">  <div class="slide snap-start">Slide 1</div>  <div class="slide snap-start">Slide 2</div>  <div class="slide snap-start">Slide 3</div></BlossomCarousel>

Options

Flickity options describe how its engine measures and aligns cells. In Blossom, most of those choices become CSS and native scroll behavior.

Flickity concept	Blossom approach
`cellAlign: "left"`	Use `scroll-snap-align: start`.
`cellAlign: "center"`	Use `scroll-snap-align: center`.
`contain`	Use native scroll bounds, padding, and `scroll-padding`.
`groupCells`	Create grouped slide elements or use native scrolling to target every nth slide.
`wrapAround`	Prefer bounded native scrolling, or use the experimental repeat pattern when an infinite effect is required. See Repeat example.
`freeScroll`	Omit `scroll-snap-align` or use `scroll-snap-type: proximity`.
`rightToLeft`	Use `dir="rtl"` or CSS `direction: rtl`.
`adaptiveHeight`	Let content define height, or update layout with `ResizeObserver`.
`prevNextButtons`	Use buttons that call `prev()` and `next()`. See Buttons example.
`pageDots`	Build dots from `IntersectionObserver` or `scrollsnapchange`. See Dots example.

For example, this Flickity setup:

Flickity

const flkty = new Flickity(".carousel", {
  cellAlign: "center",
  contain: true,
  groupCells: true,
  wrapAround: false,
});

becomes CSS:

Blossom

.carousel {
  display: grid;
  grid-auto-flow: column;
  grid-auto-columns: 25%;
  gap: 1rem;
  scroll-snap-type: inline mandatory;
  scroll-padding-inline: 10%;
}

.slide {
  scroll-snap-align: center;
}

Controls

Flickity controls call methods on the Flickity instance. Blossom exposes prev() and next() on the carousel element or component ref.

flkty.previous();flkty.next();blossom.value.prev();blossom.value.next();

For direct slide navigation, use native scrolling on the target slide.

slides[index].scrollIntoView({
  behavior: "smooth",
  inline: "center",
  block: "nearest",
});

API

Flickity commonly uses the select event and selectedIndex to track the active cell.

With Blossom, the carousel is a real scroll container, so use browser APIs such as IntersectionObserver, scrollsnapchange, or scroll events depending on the browser support you need.

flkty.on("select", () => {  setSelectedIndex(flkty.selectedIndex);});
carousel.addEventListener("scrollsnapchange", (event) => {  setSelectedIndex(event.detail.index);});
Or use IntersectionObserver for wider browser support

const slides = Array.from(carousel.children);const observer = new IntersectionObserver(   (entries) => {    const activeEntry = entries.find((entry) => entry.isIntersecting);    if (activeEntry) {      setSelectedIndex(slides.indexOf(activeEntry.target));    }  },  { root: carousel, threshold: 0.5 },);slides.forEach((slide) => observer.observe(slide));

Features

Flickity features usually become either small Blossom wrappers or native platform features.

Flickity feature	Blossom replacement
Previous / next buttons	Buttons that call `prev()` and `next()`.
Page dots	Dots backed by `IntersectionObserver` or `scrollsnapchange`.
Auto play	A timer that calls `next()` or scrolls the next slide into view.
Lazy load	Native `loading="lazy"` and `content-visibility: auto`.
As nav for	Shared selected state plus `scrollIntoView()`.
Images loaded	Native image loading events or `ResizeObserver` if layout depends on image size.
Fade	CSS scroll-driven animations or intersection state.

Keep feature migrations small. Start from a working Blossom carousel, then add behavior back only if the product still needs it.

Lifecycle

Flickity's and Blossom's lifecycle methods are similar.

Blossom initializes automatically when using framework components.

flkty.resize();flkty.destroy();blossom.init();blossom.destroy();

Migration checklist

Remove Flickity packages and install the matching Blossom package.
Import @blossom-carousel/core/style.css once.
Replace Flickity initialization with <BlossomCarousel> and direct slide children.
Move cell sizing, alignment, gaps, snapping, direction, and breakpoints into CSS.
Replace previous() and next() with prev() and next().
Replace select(index) with scrollIntoView() or native scrollTo().
Replace Flickity events with browser observers or scroll snap events.
Rebuild only the Flickity features your carousel still needs.

Next steps

Installation - Pick the package for your framework.
Snapping - Configure scroll snap behavior with CSS.
Buttons - Add previous and next controls.
Dots - Track the active slide with browser APIs.
Repeat - Explore an experimental repeating carousel pattern.
