• Fixed a critical regression where tooltips were not appearing and chart interactions were completely blocked
• The <foreignObject> element, which contains the legend wrapper, was incorrectly positioned as the last child in the SVG DOM, causing it to overlay and block all mouse events on the chart
• Restored the correct DOM ordering by ensuring <foreignObject> is always the first child element (at the back of the z-order), allowing chart interactions to work properly
• This issue affected all chart types including column, scatter, heatmap, bar, and others
• The regression was introduced in v5.5.0 when accessibility features were added

• Added extensive test coverage to prevent future regressions of DOM element ordering

If you experienced tooltip or interaction issues in v5.5.0/v5.5.1, this release fully resolves those problems. Simply upgrade to v5.6.0 - no code changes required on your end.

ApexCharts now fully supports SSR for Next.js, Nuxt, SvelteKit, Astro, and other modern meta-frameworks! This has been one of the most requested features. (#4288)

Server-side rendering:

import ApexCharts from 'apexcharts/ssr'

const chartHTML = await ApexCharts.renderToHTML({
  series: [{ data: [30, 40, 35, 50, 49, 60, 70] }],
  chart: { type: 'bar' }
}, {
  width: 500,
  height: 300
})

Client-side hydration:

import ApexCharts from 'apexcharts/client'

// Hydrate specific chart
ApexCharts.hydrate(document.getElementById('my-chart'))

// Or hydrate all charts on the page
ApexCharts.hydrateAll()

Package exports:

• Browser: import ApexCharts from 'apexcharts' (or apexcharts/client)
• Node.js/SSR: import ApexCharts from 'apexcharts/ssr'
• Automatic environment detection via conditional exports

Added comprehensive accessibility features to make charts usable for everyone:

• ARIA labels and roles
• Keyboard navigation support
• Screen reader compatibility
• Semantic HTML structure

Browser bundles:

• apexcharts.esm.js: 878 KB (unminified)
• apexcharts.common.js: 462 KB (minified CommonJS)
• apexcharts.min.js: 462 KB (minified UMD)

SSR bundles (new!):

• apexcharts.ssr.esm.js: 891 KB (unminified ESM for Node.js)
• apexcharts.ssr.common.js: 467 KB (minified CommonJS for Node.js)

None! This release is fully backward compatible with v5.4.0.

• Complete tooling overhaul: Migrated from Rollup + Webpack + Babel to Vite for faster builds and better developer experience
• Testing modernization: Transitioned from Jest to Vitest for improved performance and native ESM support
• Removed SVG.js dependency: Replaced with a custom lightweight SVG utility, reducing bundle size and external dependencies

• Optimized object cloning - Significantly improved performance for data processing
• DOM query caching - Reduced redundant DOM lookups for better rendering performance
• Event delegation - Implemented event delegation pattern to improve event handling performance
• Treemap optimization - Enhanced Treemap-squared.js algorithm for better performance

• Fixed y-axis title getting cut off when using formatter (#5152)
• Fixed annotation rectangles drifting when browser zoom level is not 100%
• Fixed x-axis label repetition for very small numeric values (#5127)
• Fixed bar chart top rounding issues
• Fixed area chart fill color when using CSS variables
• Fixed shared tooltip showing invisible series
• Fixed stack-column-outline chart rendering issues
• Removed obsolete polyfills from all samples
• Converted Treemap to proper ES module export
• Created ChartFactory for future tree-shaking support
• Legend font-size now supports units other than pixels (rem, vh, etc.) (#5151)

• Refactored data handling architecture
• Applied code quality improvements across the codebase
• Improved unit test coverage across utility functions, datetime, and data processing modules

• Comprehensive unit test improvements across the library
• Enhanced E2E testing infrastructure
• Updated sample charts
