The ultimate logical consequence of blocking = theft is the criminalisation of the inalienable right to privacy. -

Replace Google CDN

But in China, due to some reasons, the world's fastest CDN has become the world's slowest. So, I wrote this plugin/extension to replace Google's CDN with a domestic one. This plugin/extension can replace the cdn resources with domestic ones. -

eslint-plugin-vue
ESLint plugin for Vue.js
ESLint plugin for Vue.js. This plugin allows us to check the template and script of .vue files with ESLint, as well as Vue code in .js files. This plugin supports the basic syntax of Vue.js 3.2, script setup, and CSS variable injection, but the ref sugar, an experimental feature of Vue.js 3.2, is not yet supported. If you have issues with these, please also refer to the FAQ. If you can't find a solution, search for the issue and if the issue doesn't exist, open a new issue. Be aware that depending on the code samples you write in tests, the RuleTester parser property must be set accordingly (this can be done on a test-by-test basis). The default JavaScript parser must be replaced because Vue.js single file components are not plain JavaScript, but a custom file format. vue-eslint-parser is a replacement parser that generates an enhanced AST with nodes that represent specific parts of the template syntax, as well as the contents of the script tag.
