wevu-best-practices

Original：🇺🇸 English

Translated

Apply Vue-3-style runtime best practices for wevu in mini-programs. Use when implementing pages/components/stores with wevu, defining lifecycle hooks, handling setData diff behavior, designing props/emit and bindModel flows, integrating with weapp-vite SFC JSON macros, or troubleshooting compatibility differences versus Vue 3.

Overview

Write mini-program business logic with Vue-style ergonomics while respecting wevu runtime constraints. Keep hooks, state updates, and component contracts explicit.

Workflow

Set runtime conventions first

Import runtime APIs only from
```
wevu
```
.
Use
```
defineComponent
```
as the registration model for both pages and components.
Keep
```
data
```
as a function when using options-style state.

Use correct component/page boundaries

Define mini-program config via Script Setup JSON macros first.

For App/Page/Component SFC, prefer

defineAppJson

definePageJson

defineComponentJson

over

<json>

blocks.

Declare
```
usingComponents
```
through JSON config, not script-side ESM component registration.
Keep page hooks only in page contexts.

Keep reactive updates predictable

Use
```
ref/reactive/computed
```
for state and derive template data from them.
Register lifecycle hooks synchronously inside
```
setup()
```
.
Use explicit bindings for forms/events when semantics are complex.

Design events and two-way binding intentionally

Use
```
ctx.emit(event, detail, options)
```
with mini-program event semantics.
For reusable field bindings, prefer
```
bindModel
```
/
```
useBindModel
```
with explicit event and parser.
Avoid assuming full Vue web
```
v-model
```
feature parity in mini-program templates.

Structure stores for maintainability

Prefer Setup Store for simple domains and strong inference.
Use
```
storeToRefs
```
when destructuring state/getters.
Add
```
createStore()
```
only when global plugin/persistence hooks are needed.

Handle compatibility and testing explicitly

Do not use DOM/browser-only APIs in runtime logic.
For Node/Vitest tests, stub
```
Component
```
/
```
wx
```
when testing runtime bridges.
Treat lifecycle and provide/inject differences as platform constraints, not bugs.

Guardrails

Avoid hook registration after
```
await
```
in
```
setup()
```
.
Avoid direct state destructuring without
```
storeToRefs
```
for stores.
Avoid relying on undocumented Vue web-only behavior in templates or lifecycle timing.

Completion Checklist

API imports come from
```
wevu
```
, not
```
vue
```
runtime in business code.
Page/component JSON config strategy is consistent.
Hook registration timing is synchronous and predictable.
Store usage follows singleton +
```
storeToRefs
```
conventions.
Template bindings match mini-program-supported semantics.
