} catch (error) { console.error(error); } } main(); 类型化的Promise TypeScript允许你为Promise指定类型,这有助于在处理异步操作时提供更好的类型检查: // asyncFunction.ts interface User { id: number; name: string; } async function fetchUser(userId: number): Promise<User> { // ...异步...

一旦我们为所有的端点生成了TypeScript类型,我们仍然需要以一种可用的方式将它们放入代码库中。我们决定将生成的响应类型编织到生成的配置中,然后更新EtsyFetch,在它返回的Promise中使用这些类型。把所有这些放在一起大致是这样的: 代码语言:javascript 代码运行次数:0 ...

We are first importing thecommon.routes.configfile, then theexpressmodule. We then define theUserRoutesclass, saying that we want it to extend theCommonRoutesConfigbase class, which implies that we promise that it will implementconfigureRoutes(). ...
Error Handling for Background Jobs⚠️ Background jobs triggered bystartExecutionmay throw errors. Unlike thewaitForCompletioncase, the caller has no reference to the corresponding job promise which executes in the background. Therefore, errors from background jobs are captured by the semaphore and...
