How to configure and use UniApp to implement grayscale publishing and AB testing

UniApp implements the configuration and use of grayscale release and AB testing

[Introduction]
Grayscale release and AB testing are common technical means in today’s software development, used to reduce risks and improve User experience and verification of product improvement effects. As a cross-platform mobile application development framework, UniApp also provides configuration and usage methods for grayscale publishing and AB testing. This article will introduce the specific steps and give code examples.

[1. Grayscale Release]
Grayscale release is a strategy to gradually introduce new features or changes into the product. By only making new features available to some users, potential problems can be discovered in a timely manner and gradually expanded to control risks. The following are the configuration steps for UniApp to implement grayscale publishing:

1. Add a field gray_list in the manifest.json file of the UniApp project for configuring participation Percentage of users posting in grayscale.

The sample code is as follows:

{
  "gray_list": ["10%"]
}

2. In pages or components that need to be published in grayscale, determine whether to display new functions based on the value of gray_list.

The sample code is as follows:

<template>
  <view>
    <view v-if="isGrayListUser">新功能展示</view>
    <view v-else>旧功能展示</view>
  </view>
</template>

<script>
export default {
  computed: {
    isGrayListUser() {
      const grayList = ["10%"]; // 获取灰度发布的配置
      const userHash = this.$store.state.user.hash; // 获取用户标识
      const userIndex = parseInt(userHash.slice(-2), 16);
      const grayListIndex = parseInt(grayList[0].slice(0, -1));
      return userIndex < grayListIndex; // 判断用户是否在灰度白名单中
    }
  }
}
</script>

[2. AB test]
AB test is to divide different versions of the product into a group, and then compare the different versions. The performance of different versions among user groups is used to determine which version is better. The following are the configuration steps for UniApp to implement AB testing:

1. Add a field ab_version in the manifest.json file of the UniApp project to configure participating AB List of tested versions.

The sample code is as follows:

{
  "ab_version": ["A", "B"]
}

2. In the page or component that requires AB testing, judge the displayed content based on the value of ab_version.

The sample code is as follows:

<template>
  <view>
    <view v-if="version === 'A'">版本 A 的内容</view>
    <view v-else-if="version === 'B'">版本 B 的内容</view>
  </view>
</template>

<script>
export default {
  computed: {
    version() {
      const abVersion = ["A", "B"]; // 获取 AB 测试的配置
      const userHash = this.$store.state.user.hash; // 获取用户标识
      const userIndex = parseInt(userHash.slice(-2), 16);
      const versionIndex = userIndex % abVersion.length;
      return abVersion[versionIndex]; // 根据用户标识获取对应的版本
    }
  }
}
</script>

[Summary]
As a cross-platform mobile application development framework, UniApp provides the configuration and use of grayscale publishing and AB testing. Methods can help development teams reduce risks, improve user experience and verify product improvement effects. By studying the steps and code examples introduced in this article, I believe you can easily implement grayscale publishing and AB testing functions in your UniApp project.
