    chrome-extensions-examples

    chrome-extensions-examples

    All Chrome Extension examples collected into one repository

    This is not an official mirror of the Chrome extension examples. Report any issues with the examples themselves to Google's issue trackers/forums. The Chrome Extensions examples did not exist as a Git repository, and browsing both the samples page and the VCViewer did not seem particularly handy. So, I decided to scrape the content into this repository for easier browsing and (possible) editing.

    eslint-plugin-vue

    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.
