Cumulative Release v4.19.0 - v4.19.1

🔥 CHANGES (inlining SVG)

• Inline <img src="icon.svg">:
  • OLD: replaces <img> with <svg> tag
  • NEW: inline SVG as base64-encoded data URL. Use new svg.inline.embed = true option to keep old behavior.
• Encoding of data URL:
  • OLD: defaults, escaped URL (#% chars only), e.g. data:image/svg+xml,<svg>...</svg>
  • NEW:
    • defaults, base64 encoded, e.g. data:image/svg+xml;base64,iVBO...
    • full escaped URL, e.g. data:image/svg+xml,%3Csvg%20... regards generator.dataUrl.encoding option.

✨ Features

• Added support the ?inline URL query to force inline an image as dataURL in HTML, JS and CSS. The encoding can be specified using a query value (base64 or escape):

  <img src="./icon.svg?inline"/>        --> src as data URL regards configured encoding, defaults base64
  <img src="./icon.svg?inline=base64"/> --> <img src="data:image/svg+xml;base64,PHN2Zy..."/>
  <img src="./icon.svg?inline=escape"/> --> <img src="data:image/svg+xml,%3Csvg%20...%2F%3E"/>

• Added support the ?embed URL query to replace <img> with <svg> tag kipping img attributes:

  <img class="icon" src="./icon.svg?embed"/>

  Result:

  <svg class="icon" ...>...</svg>

• When inlining SVG as a data URL, consider Webpack's generator.dataUrl() and generator.dataUrl.encoding options.

• Display a warning when used ?embed URL query for SVG files in JS or CSS.

• New svg plugin option:

  type SvgOptions = {
    enabled?: boolean;
    // RegEx to match SVG files.
    // Defaults `/\.svg/i`.
    test?: RegExp;
    inline?: {
      // Enable inline SVG by replacing <img> with <svg>, only in HTML.
      // Equivalent to query: `?inline=embed` | `?embed`.
      // Defaults `false`.
      embed?: boolean;
      // Data URL encoding, overrides `generator.dataUrl.encoding` option.
      // Equivalent to query: `?inline=base64` | `?inline=escape`.
      // Defaults the `generator.dataUrl.encoding` option, if undefined then `base64`.
      encoding?: 'base64' | false;

Looks like html-bundler-webpack-plugin is up-to-date now, so this is no longer needed.
