A brief analysis of how to handwrite components in Vue applications

Vue is currently one of the most popular front-end frameworks. In front-end development, using Vue’s scaffolding tools can quickly build engineering projects that comply with specifications. However, sometimes we can also choose not to use scaffolding and hand-write Vue components to develop applications. This article will introduce how to handwrite components in Vue applications, as well as its advantages and disadvantages.

Handwritten Vue components

In Vue applications, we can use Vue.component() to register a global component or use components inside the component Properties register local components. By handwriting Vue components, we do not need to use scaffolding and can implement component logic more flexibly. The following is a handwritten counter component:

<template>
  <div>
    <p>{{ count }}</p>
    <button @click="increment">+1</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      count: 0,
    }
  },
  methods: {
    increment() {
      this.count++
    }
  }
}
</script>

In the above code, we first define a counter component. The component contains a count variable, and the counter can be incremented by one through the increment method. In the template, we use the interpolation syntax {{ count }} to display the current count value. At the same time, we also registered a click event. When the button is clicked, the increment method is called to increment the counter by one. In this way we have completed a simple counter component.

Advantages of handwritten components

Freer development method

Handwritten Vue components allow us to implement the logic of the component more freely. In projects generated using scaffolding, there are some default configurations and specification restrictions, which sometimes make it impossible for us to implement certain functions according to our own needs. The handwritten component allows us to flexibly write code according to actual needs.

Easier to understand and maintain

Handwritten Vue components can allow developers to more clearly understand the implementation principles of the components. Through handwritten components, we can better understand the principles of the component's life cycle, event mechanism, and data flow, so as to better maintain the code.

Reduce learning costs

Scaffolding tools are relatively unfamiliar to beginners, and they need to understand its usage and configuration. For handwritten components, you only need to understand the basic syntax of Vue and how to develop components. For beginners, the handwriting component is also easier to understand and use.

Disadvantages of handwritten components

The development efficiency is relatively low

Handwritten Vue components need to write code from scratch. Compared with using scaffolding tools, the development efficiency is relatively low . Through handwritten components, developers need to manually implement the logic of all aspects of the component, including life cycle, event mechanism, data flow, etc. These all require a certain amount of time and energy to achieve.

Not conducive to project expansion

For large projects, handwritten components may not be conducive to project expansion. Handwritten components may not have as strict specifications and constraints as scaffolding tools. If they are not well abstracted and encapsulated, it may cause certain difficulties in later code maintenance and expansion.

Summary

Handwritten Vue components and using scaffolding tools to develop components each have their own advantages and disadvantages. The appropriate development method should be selected based on actual needs. Handwritten components allow developers to implement component logic more flexibly, reducing learning costs and maintenance costs. However, it is relatively insufficient in terms of development efficiency and project expansion.
