A/B Smartly Vue2 SDK

A/B Smartly - Vue2 SDK

Compatibility

The A/B Smartly Vue2 SDK is a thin wrapper around the A/B Smartly JavaScript SDK

It requires Vue2 version 2.6.0+ and is supported on IE 10+ and all the other major browsers.

Note: IE 10 does not natively support Promises. If you target IE 10, you must include a polyfill like es6-promise or rsvp.

Installation

npm

npm install @absmartly/vue2-sdk --save

Directly in the browser

You can include an optimized and pre-built package directly in your HTML code through unpkg.com.

Simply add the following code to your head section to include the latest published version.

    <script src="https://unpkg.com/@absmartly/vue2-sdk"></script>

Getting Started

Please follow the installation instructions before trying the following code:

Import the SDK into your project

const absmartly = require('@absmartly/vue2-sdk');
// OR with ES6 modules:
import absmartly from '@absmartly/vue2-sdk';

Basic initialization

This example assumes an Api Key, an Application, and an Environment have been created in the A/B Smartly web console.

The Vue2 SDK is a thin wrapper around our Javascript SDK. Please check the A/B Smartly Javascript SDK docs for details regarding other options used for initialization.

// somewhere in your application initialization code, before mounting your Vue application
Vue.use(absmartly.ABSmartlyVue, {
    sdkOptions: {
        endpoint: 'https://sandbox-api.absmartly.com/v1',
        apiKey: ABSMARTLY_API_KEY,
        environment: "production",
        application: "website",
    },
    context: {
        units: {
            session_id: '5ebf06d8cb5d8137290c4abb64155584fbdb64d8',
        },
    },
    attributes: {
        user_agent: navigator.userAgent
    },
    overrides: {
        exp_test_development: 1
    }
});

This makes the $absmartly extension available in every Vue instance.

Initializing with pre-fetched Context data

When doing full-stack experimentation with A/B Smartly, we recommend creating a context only once on the server-side. Creating a context involves a round-trip to the A/B Smartly event collector. We can avoid repeating the round-trip on the client-side by sending the server-side data embedded in the first document, for example, by rendering it on the template. Then we can initialize the A/B Smartly context on the client-side directly with it. The Vue2 SDK also supports this optimized usage.

In this example, we assume the variable prefectedContextData contains the pre-fetched data previously injected.

// somewhere in your application initialization code, before mounting your Vue application
Vue.use(absmartly.ABSmartlyVue, {
    sdkOptions: {
        endpoint: 'https://sandbox-api.absmartly.com/v1',
        apiKey: ABSMARTLY_API_KEY,
        environment: "production",
        application: "website"",
    },
    context: {
        units: {
            session_id: '5ebf06d8cb5d8137290c4abb64155584fbdb64d8',
        },
    },
    attributes: {
        user_agent: navigator.userAgent
    },
    data: prefetchedContext, // assuming prefectedContext has been inject
});

Selecting a treatment

The preferred method to select a treatment is using the Treatment component with a named and scoped slot per treatment.

The slot selection rules are as follows:

• If the context is not ready:

  • If the loading slot exists, select it
  • Otherwise, select the default slot

• Otherwise, if the context is ready:

  • If a slot with the treatment alias (A, B, C, ...) exists, select it
  • Otherwise, if a slot with the treatment index exists, select it
  • Otherwise, select the default

• If the selected slot doesn't exist, nothing will be rendered

Example using the treatment alias:

<treatment name="exp_test_experiment">
    <template #A>
        <my-button></my-button>
    </template>
    <template #B="{ config }">
        <my-button :color="config.color"></my-button>
    </template>
    <template #loading>
        <my-spinner></my-spinner>
    </template>
</treatment>

Example using the treatment index:

<treatment name="exp_test_experiment">
    <template #0>
        <my-button></my-button>
    </template>
    <template #1="{ config }">
        <my-button :color="config.color"></my-button>
    </template>
    <template #2="{ config }">
        <my-other-button :color="config.color"></my-other-button>
    </template>
    <template #loading>
        <my-spinner></my-spinner>
    </template>
</treatment>

Example using only the default slot:

<treatment name="exp_test_experiment">
    <template #default="{ config, treatment, ready }">
        <template v-if="ready">
            <my-button v-if="treatment == 0"></my-button>
            <my-button v-else-if="treatment == 1" :color="config.color"></my-button>
            <my-other-button v-else-if="treatment == 2" :color="config.color"></my-other-button>
        </template>
        <template v-else><my-spinner></my-spinner></template>
    </template>
</treatment>

The scoped slot properties contain information about the A/B Smartly context and the selected treatment:

{
  "treatment": 1,
  "config": {
    "color": "red"
  },
  "ready": true,
  "failed": false
}

If the experiment is not running, or the context creation failed, the slot will be rendered with the following properties:

{
  "treatment": 0,
  "config": {},
  "ready": true,
  "failed": false
}

Setting context attributes

Attributes can be set in script.

this.$absmartly.attribute('user_agent', navigator.userAgent);

this.$absmartly.attributes({
    customer_age: 'new_customer',
});

Or directly in templates with the attributes property of the Treatment component.

<treatment name="exp_test_experiment" :attributes="{customer_age: 'returning'}">
    <template #default="{ config, treatment, ready }">
        <template v-if="ready">
            <my-button v-if="treatment == 0"></my-button>
            <my-button v-else-if="treatment == 1" :color="config.color"></my-button>
            <my-other-button v-else-if="treatment == 2" :color="config.color"></my-other-button>
        </template>
        <template v-else><my-spinner></my-spinner></template>
    </template>
</treatment>

Tracking a goal achievement

Goals are created in the A/B Smartly web console.

this.$absmartly.track("payment", 1000);

Finalizing

The finalize() method will ensure all events have been published to the A/B Smartly collector, like publish(), and will also "seal" the context, throwing an error if any method that could generate an event is called.

await this.$absmartly.finalize().then(() => {
    window.location = "https://www.absmartly.com"
})
