Easily build a checkout form

Before getting started create a free Chec merchant account on Commercejs.com then within your Chec dashboard create at least one product and retrieve your public API key.

1. Import then install VueCommercejs using Vue.use() passing your public Chec API key.

   This will

   • globally register the <chec-payment-form> component.
   • instantiate a Commerce.js client assigning it as a global variable this.$commerce. (e.g. this.$commerce.cart.retrieve().then(cart => console.log(cart)); from anywhere)

   import VueCommercejs from 'commerce-components';
   
   Vue.use(VueCommercejs, { 
     commercejsPublicKey: process.env.VUE_APP_COMMERCEJS_PUBLIC_KEY 
   });
   
   new Vue({
       render: h => h(App),
   }).$mount('#app');

2. Implement the <chec-payment-form> component synchronizing the <App>'s checkout & formData state

       <!-- ex: App.vue templae -->
       <template>
           <chec-payment-form
               useTestGateway // forces use of test_gatway when slotProp.captureOrder is called
   
               :identifierId="cartId" // also supports a permalink or id—if the prop identifierType is set to 'product_id'
               identifierType="cart" // cart by default, also supports permalink and product_id 
   
               // handles sync. checkout object, and expects checkout value to empty object {}, 
               // it will populate it automatically on mount
               :checkout.sync="checkout"
       
               // handles populating formData object with properties (customer, card, shipping) for form input(s) to bind to with v-model
               // and resets values like formData.selectedShippingMethod on checkout token object change
               :context.sync="formData"
               
               v-slot="{ captureOrder, countries, subregions, shippingOptions, shippingOptionsById }"
           >
               <!-- ^^ the slot props are important for powering dynamic parts of the form, it provides the countries, subregions, and shippingOptions list,
               a computed shippingOptionsById object, 
               and a captureOrder callback method to invoke on submit-->
   
               <input type="text" v-model="formData.customer.firstName" />
               
               <input type="number" v-model="formData.card.number" />
   
               <!-- invoke captureOrder slot-prop callback within method to handle promise, resolving with response from capture-order request -->
               <button @click="() => handleCallCaptureOrderCallBack(captureOrder)">
           </chec-payment-form> 
       </template>

   // in App.vue (example)
   // in this example, in the created() hook we're retrieving a cart, setting the cart.id in the state, and adding a product to the cart
   export default {
   name: 'app',
   created() {
       // retrieve the cart, and then add a product to the cart
       this.$commerce.cart.retrieve().then(cart => {
           this.cartId = cart.id;
           this.$commerce.products.list().then(({ data }) => {
               this.$commerce.cart.add(data[0].id);
           });
       })
   },
   data: () => ({
       // when <chec-payment-form> is mounted and created this formData will be transformed into the proper formData schema with properties 
       /* 
       customer: {
           firstName: '',
           lastName: '',
           email: '',

       },
   
       selectedShippingMethod: '',
       selectedGateway: ''
   
       card: {
           number: '', // if dev. mode, set dev friendly defaults
           expMonth: '',
           expYear: '',
           cvc: '',
           billingPostalZipcode: '',
       },
       */
       // (Note, must be passed to form as <chec-payment-form :context.sync="formData"/>)
       formData: {}, // 'formData' is an arbitrary property name, it can be any name so long it gets passed as the context.sync prop to <chec-payment-form> for it to be set-up if using slot.captureOrder
       
       // checkout token object, populated when <chec-payment-form> mounts and generates token, will be updated, and continuesly sync. with chec-payment-form (Note, must be passed to form as <chec-payment-form :checkout.sync="checkoutTokenObject"/>)
       checkout: {},
   
       cartId: '',
   }),
   methods: {
       /**
       * custom captureOrder method
       */
       handleCallCaptureOrderCallBack(captureOrderCallBack) {
           captureOrderCallBack()
               .then(resp => {
                   // can also handle successful resp by listening to, order:success, event on <chec-payment-form>
                   // https://commercejs.com/docs/api/?javascript--cjs#capture-order
                   console.log('💸💸 YAY ORDER SUCCESSFUL!', resp);
               })
               .catch((error => {
                   // handle error from #capture-order request
                   // can also handle error by listening to, order:error, event on <chec-payment-form>
               });
       },
   },
