            Vue linting errors for defineEmits function
            Asked 2022-Apr-02 at 15:36

            I'm having an issue with the linting for my Vue SPA. I'm using the defineEmits function from the script setup syntactic sugar ( The errors just do not make any sense, does anyone know how to fix this (without disabling these rules for the affected files, because it happens to every usage of defineEmits). The weird thing is that the defineProps function works without errors, which follows the same syntax. Can anyone help me out here?

            I did not find an ideal answer, but my current workaround is to use a different defineEmits syntax.

            First, this error message is indeed expected on Jan. 11th, 2022.
            See "Improving Git protocol security on GitHub".

            January 11, 2022 Final brownout.

            This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
            This will help clients discover any lingering use of older keys or old URLs.

            Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.

            As noted by Jörg W Mittag:

            There was a 4-month warning.
            The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.

            Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".

            Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.

            The permanent shutdown is not until March 15th.

            As in actions/checkout issue 14, you can add as a first step:



            ESlint - Error: Must use import to load ES Module

            Answered 2022-Mar-15 at 16:08

            I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.

            So, do this:

            • In package.json, update the line "babel-eslint": "^10.0.2", to "@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
            • Run npm i from a terminal/command prompt in the folder
            • In .eslintrc, update the parser line "parser": "babel-eslint", to "parser": "@babel/eslint-parser",
            • In .eslintrc, add "requireConfigFile": false, to the parserOptions section (underneath "ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
            • Run the command to lint a file

            Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.

            I had a similar problem with another module.

            The solution I found was to update both node (to v16) and npm (to v8).

            For Node, I used brew (but nvm should be OK).

            For npm, I used what the official doc says :

            npm install -g npm@latest

            Vue/TypeScript/ESLint/Prettier/Vetur formatting doesn't work
            Asked 2022-Feb-15 at 21:01

            Trying to get Vue/TypeScript/ESLint/Prettier/Vetur formatting in VS Code is a nightmare. There are many many GitHub issues and StackOverflow posts on this but I assure you this is not a duplicate. I have followed every tutorial and none of them work. Some of them fix one problem but introduce another. Some of them don't fix any problems. Some of them crash VS Code. Most conflict with each other in the advice they prescribe, including multiple official sources. Many are outdated, referencing obsolete config properties.

            I want VS Code to lint and format my .vue and .ts files when I save.

            I have spent hours and tried many, many configurations from different posts and tutorials, but this is the closest I have gotten to something that works. With the below configuration, however, whenever saving a .vue file, elements in the .vue files get momentarily wrapped onto a new line, and then immediately reverted back to a single line element:

            To get Vue/TypeScript/ESLint/Prettier/Vetur working in VSCode, I followed the following steps:

            1. Installed the Vue eslint plugin by running vue add @vue/cli-plugin-eslint. NOTE: If you have a client folder directory and a server folder directory, you must first cd to your client directory before using vue add.
            2. Changed the .eslintrc.js in my Vue project. Please check this post for more information/alternatives. Basically, I made a new Vue + Typescript project and copied the eslint config to my real project. The boilerplate code didn't work completely at first so I modified it a bit:

            It looks like you have defined custom paths in your TypeScript config (usually tsconfig.json). The import plugin doesn't know about the correct location of the TypeScript config and hence cannot resolve those paths. What you need to do, is to specify the correct path to your TypeScript config via the project parameter in the resolver options:
