vue3-flag-icons

A TypeScript-compatible Vue3 component library for providing flag icons.

Install

npm install vue3-flag-icons

Usage

Firstly, you need to import the CSS. It is recommended that you do this at the app level, for example while creating and mounting your app:

main.ts:

but you could also just import the CSS whenever you import the component.

To use the component, just import it and use it:

App.vue:

<script setup lang="ts">
import FlagIcon from 'vue3-flag-icons'
</script>

<template>
  <FlagIcon code="gr" />
  <FlagIcon code="gb" :size="25" square />
  <FlagIcon code="us" size="32" circle />
  <FlagIcon code="fr" title="A flag icon" />
  <FlagIcon code="es" :title="(country) => `Country: ${country}`" />
</template>

(Note: the component is the default export so you can name it however you want. Here we have used FlagIcon, but you could just as easily use Flag or CountryFlag or whatever you want - just be consistent with your naming for code clarity.)

Props

The component takes the following props:

• code: CountryCode: the country code string, either lower or upper case, as available in the flag-icons package (a superset of the ISO 3166-1 alpha-2 codes).
• size?: string | number: the size (height) in px for the flag, defaults to the current font-size.
• square?: boolean: if true the flag will be rendered as a 1x1 square, otherwise it will be rendered as a 4x3.
• circle?: boolean: if true the flag will be rendered as a circle.
• title?: string | ((country: string) => string): the mouseover tooltip of the icon, defaults to the name of the country.

Credits

• Inspired by vue-flag-icon, a similar non-TypeScript-compatible Vue2 project.

• Uses the flag-icons package for all the flags.
