Remove Vue 2 support and the .extend method

[dwightjack]

Drop Vue 2 support

Vue 2 reached End of Life (EOL) on December 31st, 2023. By dropping Vue 2 compatibility we can deliver a smaller package and make the source code more maintainable.

Removed VueTypes.extend method

VueTypes.extend was deprecated in v5. In v6 this method has been removed. Please migrate your code to use ES6+ extends feature.

Example:

Using VueTypes.extend (old):

import VueTypes from 'vue-types';

export const VueTypesProject = VueTypes.extend([
  {
    name: 'maxLength',
    type: String,
    validator: (max, v) => v.length <= max,
  },
  {
    name: 'positive',
    getter: true,
    type: Number,
    validator: (v) => v > 0,
  },
])

Using ES6+ extends (new):

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

export class VueTypesProject extends VueTypes {
  static maxLength(max) {
    return toType('maxLength', {
      type: String,
      validator: (v) => String(v).length <= max,
    })
  }

  static get positive() {
    return toType('positive', {
      type: Number,
      validator: (v) => v > 0,
    })
  }
}

Package format review:

• ESM and CJS builds target is ESNext (browsers with support for the latest JavaScript features).
• UMD builds target is ES2016 (aligned with Vue 3 browser support)

If you're using a bundler, you should not encounter any issue.

If you are directly referencing or importing a specific file in the dist or shim folder, you might need to update its path as described in the following table:

Old (v5)	New (v6)
dist/vue-types.m.js	dist/index.mjs
dist/vue-types.modern.js	dist/index.mjs
dist/vue-types.cjs	dist/index.cjs
dist/vue-types.umd.js	dist/index.umd.js
dist/shim.m.js	dist/shim.mjs
dist/shim.modern.js	dist/shim.mjs
dist/shim.cjs	dist/shim.cjs
dist/shim.umd.js	dist/shim.umd.js
shim/index.m.js	dist/shim.mjs
shim/index.modern.js	dist/shim.mjs
shim/index.cjs	dist/shim.cjs
shim/index.umd.js	dist/shim.umd.js
