Ux Chartjs Laravel Package
symfony/ux-chartjs
Symfony UX Chart.js integrates the Chart.js library into Symfony apps, letting you render interactive charts directly from PHP with Twig components and Stimulus controllers, no custom JavaScript required.
Chart.js integration for Symfony
Frequently asked questions about Ux Chartjs
- What is symfony/ux-chartjs used for?
- It is a Symfony UX bundle that integrates Chart.js into Symfony applications. You define chart data and options in PHP or Twig and render interactive charts through a Twig component and Stimulus controller, avoiding custom JavaScript for standard charts.
- Does symfony/ux-chartjs work with Laravel?
- No, it is built for Symfony, not Laravel. It relies on Symfony bundles, Twig components, and the Symfony UX Stimulus bridge, so it will not drop into a Laravel app without significant custom work. Laravel developers should evaluate Laravel-specific Chart.js wrappers or integrate Chart.js manually.
- How do I install symfony/ux-chartjs?
- Install it with Composer using a version constraint such as symfony/ux-chartjs:^3.6, then follow the Symfony UX setup for your asset pipeline. With AssetMapper, ensure symfony/asset-mapper 8.2 or later to pick up the #3919 compatibility fix. The README now uses an X.Y.Z placeholder, so pin an explicit version in your install docs.
- Which Symfony and PHP versions does symfony/ux-chartjs 3.6 support?
- The 3.x line aligns with Symfony UX 3.x, Symfony 7.4+/8.x, and PHP 8.4+ based on the release assessment. Verify the bundle's composer.json constraints before committing to Symfony 8.x, because the tested matrix may be broader than the 7.4+ framing. The older 2.x line targets previous Symfony stacks.
- Do I need Node.js or Webpack Encore to use symfony/ux-chartjs?
- Not necessarily. As of v3.6.0, the AssetMapper conflict fix (#3919) makes AssetMapper and importmap a viable first-class path with no Node dependency, provided symfony/asset-mapper is 8.2 or later. Vite and Webpack Encore remain supported options, though Encore is legacy-track for Symfony 7.x and 8.x.
- How do I render a chart from PHP with symfony/ux-chartjs?
- Use the Twig component, for example <twig:Chart>, with data and options defined in a controller or template. You can pass datasets, labels, and Chart.js options as PHP arrays, and the Stimulus controller initializes Chart.js client-side. Standard chart types such as line, bar, pie, doughnut, and radar need no custom JavaScript.
- Does symfony/ux-chartjs support Chart.js 4 plugins like datalabels or zoom?
- It targets Chart.js 4.x, so plugins must be v4-compatible, such as chartjs-plugin-datalabels 2.x and chartjs-plugin-zoom 2.x or later. With Vite, add plugins to optimizeDeps.include to avoid dependency optimization issues. Plugin drift remains a frontend risk, so pin plugin versions and smoke-test your charts.
- Can I use symfony/ux-chartjs with Symfony Live Components for reactive charts?
- Yes, the chartjs:view-value-change re-render behavior supports Live Components, so chart updates can happen without SPA complexity. The 3.6.0 release does not affect this behavior. You still provide data server-side and let the Stimulus bridge handle re-rendering.
- How should I test and deploy symfony/ux-chartjs in production?
- Branch first, run composer update --with-dependencies, check composer why-not symfony/asset-mapper, and smoke-test one chart end-to-end. In production, watch server-render TTFB, pin Chart.js and plugin versions, and confirm your asset pipeline configuration for AssetMapper, Vite, or Encore. Renamed Stimulus events and missing Vite optimizeDeps entries are common failure points.
- What alternatives should Laravel or Symfony developers consider to symfony/ux-chartjs?
- For Symfony, alternatives include rendering Chart.js manually, using other UX bundles, or serving chart data to an API-driven frontend. For Laravel, look at Laravel Chart.js packages or a custom Blade plus Chart.js integration, since symfony/ux-chartjs is Symfony-specific. Evaluate maintenance, Chart.js version support, and asset pipeline fit before choosing.
