Eslint-plugin-vue-types NPM

eslint-plugin-vue-types

ESLint plugin for vue-types and eslint-plugin-vue

eslint-plugin-vue version note

Since eslint-plugin-vue@7, the vue/require-default-prop rule ignores props assignment by call expressions (VueTypes.arrayOf(String)) or object properties (VueTypes.array). So you don't need this plugin anymore.

If you are using an older version of eslint-plugin-vue consider upgrading it.

--- Original Documentation ---

Warning: This is the documentation for eslint-plugin-vue-types@^2.0.0. The documentation for v.1 is available here.

This plugin should be used alongside eslint-plugin-vue to allow the usage of vue-types validators as valid prop definitions with the [] rule (see vue-types#29 and vue-types#179 for details).

Requirements

eslint-plugin-vue ^6.0.0

ESLint >=5.0.0.
Node.js >=10.0.0

Installation

npm install --save-dev eslint eslint-plugin-vue eslint-plugin-vue-types

Usage

This plugin provides a single rule: vue-types/require-default-prop.

The rule extends vue/require-default-prop preventing it from reporting errors for props defined with VueTypes namespaced validators (like VueTypes.string or VueTypes.oneOf([...])). It also allows individually imported validators.

In your eslint configuration add plugin:vue-types/recommended after any plugin:vue/* preset.

{
  "extends": ["plugin:vue/recommended", "plugin:vue-types/recommended"]
}

This will filter errors for prop definitions like:

import VueTypes, { string } from 'vue-types'

export default {
  props: {
    msg1: string().isRequired, // no error reported
    msg2: VueTypes.string, // no error reported
    msg3: VueTypes.shape({}).loose.isRequired, // no error reported
  },
}

Note: For this plugin to work properly, ensure that the .isRequired flag always comes last in the chain:

import { shape } from 'vue-types'

export default {
  props: {
    msg1: shape({ ... }).loose.isRequired, // no error reported

    msg2: shape({}).isRequired.loose, // ERROR!
  },
}

Customization

Custom namespaces

By default vue-types/require-default-prop will not report VueTypes validators when used with the VueTypes namespace.

import VueTypes from 'vue-types'

const theme = VueTypes.oneOf(['dark', 'light'])

export default {
  props: {
    name: VueTypes.string, // <-- not an error
    theme, // <-- error
  },
}

To prevent this error you can wrap custom validators in a namespace and add it to the plugin's allowed namespaces:

// .eslintrc.json
{
  "extends": ["plugin:vue/recommended", "plugin:vue-types/recommended"],
  "settings": {
    "vue-types/namespace": ["AppTypes"]
  }
}

import VueTypes from 'vue-types'

const AppTypes = {
  theme: VueTypes.oneOf(['dark', 'light']),
}

export default {
  props: {
    name: VueTypes.string, // <-- not an error
    theme: AppTypes.theme, // <-- not an error
  },
}

Custom import sources

By default vue-types/require-default-prop will not report VueTypes individual validators when imported from the vue-types module.

To extend this feature to other modules, include them in the vue-types/sources setting:

// .eslintrc.json
{
  "extends": ["plugin:vue/recommended", "plugin:vue-types/recommended"],
  "settings": {
    "vue-types/sources": ["~/utils/prop-types"]
  }
}

import { string } from 'vue-types'
import { myValidator } from '~/utils/prop-types'

export default {
  props: {
    name: string(), // <-- not an error
    msg: myValidator(), // <-- custom validator, not an error
  },
}

Note: This feature is only available for static import statements.
