What is eslint-plugin-vue?
The eslint-plugin-vue npm package is a plugin for ESLint specifically designed for Vue.js applications. It provides linting rules that are tailored to the Vue.js framework, helping developers to write consistent and error-free code by following best practices and avoiding common mistakes.
What are eslint-plugin-vue's main functionalities?
Style Guide Enforcement
Enforces a style guide by limiting the number of attributes per line in Vue templates. This helps in maintaining readability and consistency in the codebase.
"vue/max-attributes-per-line": ["error", { "singleline": 3, "multiline": { "max": 1, "allowFirstLine": false } }]
Component Naming
Ensures that component names in templates are written in a specific case, such as PascalCase, which is a common convention in Vue.js projects.
"vue/component-name-in-template-casing": ["error", "PascalCase"]
Avoiding Deprecated Features
Prevents the use of deprecated features like the 'slot' attribute, encouraging developers to use the updated syntax and features of Vue.js.
"vue/no-deprecated-slot-attribute": "error"
Prop Validation
Ensures that every prop has a default value, which can prevent bugs and make the components more predictable.
"vue/require-default-prop": "error"
Script Indentation
Enforces consistent indentation in the script section of Vue single-file components, which improves code readability and maintainability.
"vue/script-indent": ["error", 2, { "baseIndent": 1, "switchCase": 1, "ignores": [] }]
