eggjs Of issues Have seen similar problems ,

https://github.com/eggjs/egg/issues/2388

But the official website documents have clearly stated , Load back first js file Post load ts file , I always thought it was eggjs The problem of ;

function npm start Will not load ts

I didn't think so typeorm Configuration problem of ,entity The configuration is ts file , The production environment needs to be configured js file

typeorm It doesn't load automatically entity Of js file

solve

development environment entity load ts file , Production environment load js file
