type OrderEvent = { order_id: string; amount: number; item: string; } After you define the type or interface, use it in your handler's signature to ensure type safety: export const handler = async (event: OrderEvent): Promise<string> => { During compilation, TypeScript validates that ...
基于类型的声明方式:当使用TypeScript时,可以通过在defineProps后添加泛型来指定props的类型。这种方式能够实现静态类型检查,提高代码的可靠性和可维护性。 3. 示例:在Vue 3中使用defineProps设置类型 以下是一个使用TypeScript和<script setup>语法糖的示例,展示了如何在Vue 3组件中使用defineProps设置属性类型...

Vite uses [esbuild defines](https://esbuild.github.io/api/#define) to perform replacements, so value expressions must be a string that contains a JSON-serializable value (null, boolean, number, string, array, or object) or a single identifier. For non-string values, Vite will automatically...
