Now Learn JavaScript Programming Language With Microsoft

icrosoft has released a new series of video tutorials on YouTube for novice programmers to get a hands-on renowned programming language — JavaScript.

This isn’t the first attempt by Microsoft to come up with video tutorials by beginner programmers. The company also has a series of YouTube tutorials on Python for beginners.

For JavaScript, Microsoft has launched a series of 51 videos as ‘Beginner’s Series to JavaScript,’ for young programmers, developers and coders who are interested in building browser applications using JavaScript. These video tutorials will also help programmers and coders to use relevant software development kits (SDKs) and JavaScript frameworks, such as Google’s Angular.

“Learning a new framework or development environment is made even more difficult when you don’t know the programming language,” stated on the Microsoft Developer channel on YouTube. “Fortunately, we’re here to help! We’ve created this series of videos to focus on the core concepts of JavaScript.”

It further stated — while the tutorials don’t cover every aspect of JavaScript, it indeed will help in building a foundation from which one can continue to grow. By the end of this series, Microsoft claims that the novice programmers will be able to work through tutorials, quick starts, books, and other resources, continuing to grow on their own.

A Vue 2 Component Collection for Stripe.js

Vue Stripe Elements

Flexible and powerful Vue components for Stripe. It's a glue between Stripe.js and Vue component lifecycle.

  • Vue 2 component collection: stable ✅
  • Vue 3 version: in development 🚧

Quickstart

1. Install package:

# npm
npm i vue-stripe-elements-plus --save-dev

# yarn
yarn add vue-stripe-elements-plus --dev

2. Add Stripe.js library to the page:

<script src="https://js.stripe.com/v3/"></script>

Alternatively, you can load Stripe library dynamically. Just make sure it's ready before your components mount.

3. Use built-in components

Create card

<template>
  <div class="payment-simple">
    <StripeElements
      :stripe-key="stripeKey"
      :instance-options="instanceOptions"
      :elements-options="elementsOptions"
      #default="{ elements }" // attention: important part!
      ref="elms"
    >
      <StripeElement
        type="card"
        :elements="elements"
        :options="cardOptions"
        ref="card"
      />
    </StripeElements>
    <button @click="pay" type="button">Pay</button>
  </div>
</template>

<script>
import { StripeElements, StripeElement } from 'vue-stripe-elements-plus'

export default {
  name: 'PaymentSimple',

  components: {
    StripeElements,
    StripeElement
  },

  data () {
    return {
      stripeKey: 'pk_test_TYooMQauvdEDq54NiTphI7jx', // test key, don't hardcode
      instanceOptions: {
        // https://stripe.com/docs/js/initializing#init_stripe_js-options
      },
      elementsOptions: {
        // https://stripe.com/docs/js/elements_object/create#stripe_elements-options
      },
      cardOptions: {
        // reactive
        // remember about Vue 2 reactivity limitations when dealing with options
        value: {
          postalCode: ''
        }
        // https://stripe.com/docs/stripe.js#element-options
      }
    }
  },

  methods: {
    pay () {
      // ref in template
      const groupComponent = this.$refs.elms
      const cardComponent = this.$refs.card
      // Get stripe element
      const cardElement = cardComponent.stripeElement

      // Access instance methods, e.g. createToken()
      groupComponent.instance.createToken(cardElement).then(result => {
        // Handle result.error or result.token
      })
    }
  }
}
</script>

4. Get advanced

Create multiple elements

<StripeElements
  :stripe-key="stripeKey"
  :instance-options="instanceOptions"
  :elements-options="elementsOptions"
  #default="{ elements }" // attention: important part!
>
  <StripeElement
    type="cardNumber"
    :elements="elements"
    :options="cardNumberOptions"
  />
  <StripeElement
    type="postalCode"
    :elements="elements"
    :options="postalCodeOptions"
  />
</StripeElements>

5. Go wild

You can even create multiple groups, don't ask me why. It's possible.

<StripeElements
  :stripe-key="stripeKey1"
  :instance-options="instanceOptions1"
  :elements-options="elementsOptions1"
  #default="{ elements }" // attention: important part!
>
  <StripeElement
    :elements="elements"
    :options="cardOptions"
  />
</StripeElements>
<StripeElements
  :stripe-key="stripeKey2"
  :instance-options="instanceOptions2"
  :elements-options="elementsOptions2"
  #default="{ elements }" // attention: important part!
>
  <StripeElement
    type="iban"
    :elements="elements"
    :options="ibanOptions"
  />
</StripeElements>

Styles

No base style included. Main reason: overriding it isn't fun. Style as you wish via element options: see details.

API Reference

StripeElements.vue

Think of it as of individual group of elements. It creates stripe instance and elements object.

import { StripeElements } from 'vue-stripe-elements-plus'

props

// https://stripe.com/docs/js/initializing#init_stripe_js-options
stripeKey: {
  type: String,
  required: true,
},
// https://stripe.com/docs/js/elements_object/create#stripe_elements-options
instanceOptions: {
  type: Object,
  default: () => ({}),
},
// https://stripe.com/docs/stripe.js#element-options
elementsOptions: {
  type: Object,
  default: () => ({}),
},

data

You can access instance and elements by adding ref to StripeElements component.

// data of StripeElements.vue
instance: {},
elements: {},

default scoped slot

Elegant solution for props. Really handy because you can make instance and elements available to all children without adding extra code.

<!-- Isn't it cool? I really like it! -->
<StripeElements #default="{elements, instance}">
  <StripeElement :elements="elements" />
  <CustomComponent :instance="instance" />
</StripeElements>

StripeElement.vue

Universal and type agnostic component. Create any element supported by Stripe.

props

// elements object
// https://stripe.com/docs/js/elements_object/create
elements: {
  type: Object,
  required: true,
},
// type of the element
// https://stripe.com/docs/js/elements_object/create_element?type=card
type: {
  type: String,
  default: () => 'card',
},
// element options
// https://stripe.com/docs/js/elements_object/create_element?type=card#elements_create-options
options: {
  type: [Object, undefined],
},

data

stripeElement
domElement

options

Element options are reactive. Recommendation: don't use v-model on StripeElement, instead pass value via options.

data() {
  return {
    elementOptions: {
      value: {
        postalCode: ''
      }
    }
  }
},

methods: {
  changePostalCode() {
    // will update stripe element automatically
    this.elementOptions.value.postalCode = '12345'
  }
}

events

Following events are emitted on StripeElement

  • change
  • ready
  • focus
  • blur
  • escape
<StripeElement
  :elements="elements"
  @blur="doSomething"
/>

Helpers

In case you like the manual gearbox. Check stripeElements.js for details.

import { initStripe, createElements, createElement } from 'vue-stripe-elements-plus'
