How to customize error page in uniapp

With the vigorous development of mobile Internet, mobile APP has become a necessity for people’s daily life. In order to meet the needs of users, APP development has become more and more cumbersome and complex. Cross-platform development frameworks like uniapp provide developers with a more convenient development method. But during use, we will inevitably encounter some errors or exceptions. In this case, if we do not design the error page well, it may leave a bad impression on users and even lead to user churn. Therefore, this article will detail how to customize error pages in uniapp.

1. The role of error pages

First of all, we need to understand the role of error pages. When we encounter an error or abnormal situation in the APP, if there is no error page to display, it may cause the APP to directly crash or have adverse reactions such as crashing. By designing a well-designed error page, we can let users better understand the cause of the error and tell them how to solve the problem. If our error page can be designed very well, it can even make users feel that our APP is still very stylish after an error occurs.

2. How to customize the error page in uniapp

Next, let’s introduce how to customize the error page in uniapp.

1. Use uniapp's built-in error page

uniapp provides a built-in error page that will be automatically displayed when an abnormality occurs in the APP. Although this method is convenient, its shortcomings are also obvious, that is, the page effect is not good and cannot meet our personalized needs.

2. Custom error component

In order to solve the above shortcomings, we can consider using custom components to implement error pages. The Error component is provided in uniapp. We only need to define the Error component in App.vue to implement a custom error page. The following is a simple sample code:

// App.vue

<template>
    <view class="container">
        <error content="出错了，请稍后再试" @retry="onRetry"></error>
        <router-view />
    </view>
</template>

<script>
import Error from '@/components/Error.vue';

export default {
    components: {
        Error
    },
    methods: {
        onRetry() {
            // 重新加载页面
        }
    }
};
</script>

// Error.vue

<template>
    <view class="error">
        <text class="content">{{ content }}</text>
        <view class="button" @click="$emit(&#39;retry&#39;)">重试</view>
    </view>
</template>

<script>
export default {
    props: {
        content: {
            type: String,
            default: '出错了，请稍后再试'
        }
    }
};
</script>

Through the above code, we have successfully customized the Error component and achieved personalized display of the error page. We can beautify the page as needed to give users a good impression of our APP.

3. Design principles of error pages

When designing error pages, we need to follow the following principles:

1. Display error information

The error page needs to display error information clearly and clearly so that users can better understand the cause of the error.

2. Guide users to solve problems

Error pages need to tell users how to solve problems. For example, provide some solutions or direct users to contact customer service.

3. Provide a retry mechanism

If an error page appears, some problems may only be temporary. We can provide a retry mechanism on the error page so that users can try again.

4. Beautify the page

In order to allow users to better accept the error page, we should beautify the page. This will not only make users feel good when problems arise, but also improve user retention.

4. Summary

Through the introduction of this article, we have learned the role of the error page and learned how to customize the error page in uniapp. At the same time, we also learned about the design principles of error pages. We hope that developers can apply these principles into actual development when designing error pages to provide users with a better user experience.
