关于如何处理manifest.json中的图标有什么建议？

我找到了这个生成图标的 webpack 插件。它生成了 37 个图标和相应的 html 标签。

为了获得最佳效果，我应该将图标放在 manifest.json和html 元标记中吗？拥有 37 个图标会达到什么效果，而使用 10 个图标则无法实现（我认为它是更多的移动支持，但如果 3 个图标处理 95% 的浏览器，它实际上什么也没有实现）？有哪些推荐的？

这是给服务人员的。

你是对的，这些图标中的每一个都适用于不同的设备，并且通常是所述设备的不同版本。但是，您实际上并不需要 37。要获得 37，他们会为市场份额远低于 1% 的设备生成像素完美图标。您可以为他们提供最近的匹配项，几乎没有人会注意到。我倾向于将浏览器相关图标放在 html 元标记中，并将应用程序相关图标放在清单中。

在基线上，您应该遵循以下清单的结构。更多细节可以在这个链接上找到。虽然如果你在 PWA 上运行Lighthouse，它会要求另一个大小为 512 像素的图标。
