React Hooks 规则
注意： 此规则包含在以下规则集中：
reactfresh在
deno.json 中启用完整规则集{
"lint": {
"tags": ["react"] // ...or "fresh"
}
}使用 Deno CLI 启用完整规则集
deno lint --tags=react # or ... deno lint --tags=fresh
确保在 React/Preact 组件中正确调用 Hooks。它们必须在组件的顶层调用，而不是在条件语句或循环内部调用。
无效
// WRONG: Called inside condition
function MyComponent() {
if (condition) {
const [count, setCount] = useState(0);
}
}
// WRONG: Called inside for loop
function MyComponent() {
for (const item of items) {
const [count, setCount] = useState(0);
}
}
// WRONG: Called inside while loop
function MyComponent() {
while (condition) {
const [count, setCount] = useState(0);
}
}
// WRONG: Called after condition
function MyComponent() {
if (condition) {
// ...
}
const [count, setCount] = useState(0);
}
有效
function MyComponent() {
const [count, setCount] = useState(0);
}
