I created a Procfile with npm run start:prod command, also tried moving @nestjs/cli devDependency to dependencies but it doesn't work

Edit

Apparently Nest.js build the main.js in dist/src/

CodePudding user response：

Next js goes perfectly with vercel if you are not bounded with a single option to deploy

CodePudding user response：

The start:prod command in the package.json should be updated to read "start:prod": "node dsit/src/main" due to how the project is built. Usually this means that there is a ts file outside of src that is being read as a part of the project, or some other import is happening to a file outside of the source root
