How to elegantly refactor Vue complex multi-step form?

How to gracefully handle complex multi-step forms in Vue project development?

This article will discuss a complex form with six steps. The current code of this form is concentrated in a Vue component, using v-show to control the display and hiding of steps. As business logic continues to expand, the amount of code has expanded to thousands of lines, and there are as many as hundreds of lines of variables in data, and even components such as Tab pages and Dialog are nested. More importantly, the business logic of the subsequent steps depends on the data from the previous steps, which makes code maintenance and scaling extremely difficult.

Faced with such a complex form, how can I refactor it to improve the maintainability and scalability of my code?

An effective idea is to split each step form into separate Vue components. This componentized solution can effectively solve the current problems. By encapsulating each step into independent components, the business logic and data of each step can be clearly divided, avoiding bloated code. Each component can have its own data, methods and computed properties, thereby realizing modular management of the code. Data transfer between components can be achieved through props and $emit, etc., to ensure that the data dependencies between steps can be effectively managed. For example, the output data of step one component may be used as input data of step two component to pass the data in such a chain. This componentization solution not only improves the readability and maintainability of the code, but also facilitates subsequent code expansion and reuse. Each step component can be independently developed, tested and maintained, reducing the complexity of the overall project.
