English description

manifest.json should be generated by cli-plugin-pwa and should not be copied directly from the public folder.

manifest.json is a separate file that cannot be modified by vue.config.js, and these values are very suitable for configuration with vue.config.js. For example: name, short_name, start_url, icons[].src.

Some attributes of pwa are the same or similar to those of manifest.json. For example, pwa.themeColor and manifest.theme_color, pwa.name and manifest.name.

中文说明

manifest.json应该由cli-plugin-pwa生成，不应该直接从public文件夹复制。

原本manifest.json是一个完全独立的文件，通过vue.config.js无法修改某些值，而这些值又非常合适使用vue.config.js配置。比如：name, short_name, start_url, icons[].src。

在原有的pwa的属性中，有些属性与manifest.json的属性相似或本应该是同一个。比如pwa.themeColor和manifest.theme_color, pwa.name和manifest.name。

We could also use webpack-pwa-manifest to generate the manifest instead of a simple Object.assign().

This would allow users to specify just one image/icon, which would then be down-scaled to all the required different icon sizes. That part is the biggest advantage of creating the manifest programmatically instead of by hand, im my opinion 🙂

Thanks for your PR. But to not break existing projects relying on manifest.json, we need to implement a compatibility layer for this feature:

1. if the generated manifest.json is identical to the existing one, tell the user that they can safely delete the redundant file;
2. if not identical, prefer the existing one, and output a warning that the settings are not in sync.

Also, a test case would be very much appreciated.

How can I throw a warn when build complete?
I can't find a way in other vue-cli code.
I try to use setTimeout, but can't pass the test.

Now that we are planning a v4 alpha release, The compatibility layer is no longer needed. I'll merge this PR directly. Thanks for your contribution!

Thanks again! Cheers! 💚

I see the UI hasn't be updated to not use manifest.json

This does not seem to work with the default setup using vite any longer. Looking at the code this plugin seems to hook into webpack so is this not compatible with vite? Are there plans to add this support or is this basically in maintenance-only mode and I should look for alternative solutions for vite?
