使用Node，Mysql和TypeScript解决承诺链

Question

I am working in node and typescript. I have a controller and a repository. I can log the data out all over the place EXCEPT at the return from the repo. Of course, the controller gets back nothing. Here are the pastebins:

• package.json
• users_controller.ts
• users_repository.ts

Answer 1

This is not the correct way to use Promises. The getUsers() method is called and returns before the Promise has a chance to resolve. The quickest way to fix it is to return the Promise from the getUsers() method or use async/await. Essentially, all of the logic that you have to update the userModels value happens after the function has already returned an empty array.
