Description

Integrate watermark-js-plus into VuePress。

This plugin can add watermark to the pages, you can choose between add watermark globally or on specific pages. You can also choose between add text watermark or image watermark.

[Mister-Hope]

I think the docs should be detailed telling defineWatermarkConfig can used to add hooks to watermark.

[Mister-Hope]

need some tweaks in shared folder, make sure they should be used at both side.

For example the plugin option containing pageFilter is a node side one, then it should be node/options.ts

This ensures that these kind of types can not be imported in wrong side.

LGTM, I leave a comment at a check of image, check that, maybe you want to mean or?

Currently this PR is blocked by the latest commit at main. I am still figuring out that.

BTW, could you add some e2e tests?

BTW, could you add some e2e tests?

When I run pnpm e2e:dev locally, I noticed that the webServer.command in playwright.config.ts is not being executed at all. Playwright starts running the tests without waiting for http://127.0.0.1:9080 to return 200 OK. I have to run pnpm docs:dev first before pnpm e2e:dev runs correctly.

[Mister-Hope]

Fix e2e tests plz

Done

@pengzhanbo Hi, I rebuild the plugin, and you are welcomed to review this for me.

The rebuild is containing:

• A reuseable composable which can be imported and used from @vuepress/plugin-watermark/client directly without calling the plugin.
• replace global and filter with enabled
• WatermarkPureOptions instead of WatermarkAttrOptions and WatermarkOptions is only available at client.
• Fixing options.image issue
• A lot of code refactor to improve quality.
• isInsideApp to determine whether the parent may be sensitive with routing.
