Usage without NPM

Add script dependencies

<!-- Vue Dependency -->
<script src="https://cdn.jsdelivr.net/npm/vue"></script>

<!-- Vue Currency Filter Dependency -->
<script src="https://unpkg.com/[email protected]/dist/vue-currency-filter.iife.js"></script>
<!-- Change 3.2.3 with latest version -->

Use filters in global

if (VueCurrencyFilter) {
  Vue.use(VueCurrencyFilter, {
    symbol: "£",
    thousandsSeparator: ",",
    fractionCount: 0,
    fractionSeparator: ".",
    symbolPosition: "front",
    symbolSpacing: false
  })
}

var app = new Vue({
  el: '#app',
  data: {
    curr: 1000
  }
});

Add Configuration In Specific Place

<span>
{{ textInput | currency(configSymbol, configSeparator, configFractionCount,
configFractionSeparator, configSymbolPosition, configSymbolSpacing)}}
</span>

Now configurations is also available as Object, thanks to sunhengzhe in PR #25:

<span>
{{ textInput | currency({
  symbol: '',
  thousandsSeparator: '',
  fractionCount: '',
  fractionSeparator: '',
  symbolPosition: '',
  symbolSpacing: ''
})}}
</span>

Available Options

{
  name: 'string (default: currency)', // using for multiple instance filters
  symbol: 'string (default : empty string)',
  thousandsSeparator: 'string (default : .)',
  fractionCount: 'number (default : 0)',
  fractionSeparator: 'string (default: ",")',
  symbolPosition: 'string (default: front)',
  symbolSpacing: 'boolean (default: true)'
}

Update Global Configs

Since global config only can be setted from Vue.use(VueCurrencyFilter, configs), but sometimes we need to update this global configs on runtime process.

from v3.1.0 we intoduce prototype method that can be update this global configs. You can use anywhere in your components like this code below:

this.$CurrencyFilter.setConfig(newConfigs)

But please be aware, this method is only update global configs without trigger to re-run filter function. So maybe you will face not sync data from your configs and your view. You need to update some value to trigger this new configs applied.

How to test in Unit Test

Using @vue/test-utils we can create test for any Vue Plugins, like:

/* eslint-env jest */
import { shallowMount, createLocalVue } from "@vue/test-utils";
import VueCurrencyFilter from "vue-currency-filter";

import Component from "../pages/myComponent.vue";

describe("test myComponent", () => {
  it("vue-currency-filter should working correctly", () => {
    let localVue = createLocalVue();
    localVue.use(VueCurrencyFilter, {
      symbol: "$",
      thousandsSeparator: ",",
      fractionCount: 2,
      fractionSeparator: ".",
      symbolPosition: "front",
      symbolSpacing: true
    });

    let wrapper = shallowMount(Component, {
      localVue
    });

    let result = wrapper.find(".curr");
    expect(result.text()).toEqual("$ 1,000.00");
  });
});
