Tag Archives: Vue3.0 turn off eslint

[Solved] Vue3.0 Error: The component has been registered but not used vue/no-unused-components, Close eslint

Background

When eslint is selected when creating a project, an error will be reported when there are defined but unused components or defined but unused variables.

Note: I use vue3.0.

Cause analysis

That is, the eslint default rule leads to unnecessary error reporting.

Solution:

Modify rules

If eslint is enabled and component is added, an error is reported:

The “EchartsDemo” component has been registered but not used   vue/no-unused-components

Solution: add the following under eslintconfig of package.JSON or .Eslintrc.JS (if this file exists):

    "rules": {
      "vue/no-unused-components": "off", // Turn off error reporting when there are components defined but not used
      "no-unused-vars": "off" // turn off error reporting when there are defined but unused variables
    }

Note: if both files are modified, eslintrc.JS files have higher priority.

How do I close eslint?

Scheme 1: do not use eslint, of course, you can not select eslint when creating a project, but generally encounter this problem, which is obviously the introduction of eslint.. Scheme 2: close eslint, and add a line of configuration in Vue.Config.JS : lintonsave: false .
