unplugin-inject-preload

Universal plugin to inject <link rel='preload'> tags into HTML output for Vite 4/5, Webpack 5 (with HtmlWebpackPlugin), and Rspack 1.0 (with HtmlWebpackPlugin or HtmlRspackPlugin). Current stable version is 3.0.0, released with Rspack 1.0 support and dropped support for Rspack 0.x. Replaces separate packages vite-plugin-inject-preload and html-webpack-inject-preload. Ships TypeScript types. Release cadence is irregular, with minor releases featuring breaking changes. Key differentiator: single unified API across multiple bundlers.
