Unexpected token problem

jelling commented 4 years ago

I may be barking up the wrong tree but is the library intended to fix the issue where TypeORM will not seem to work with Next.JS.

The error I get is:

/Users/jelling/dev/pw/longboard/next-js/jon/entities/person.ts:1
import { Entity, PrimaryGeneratedColumn, Column } from 'typeorm';
       ^

SyntaxError: Unexpected token {

I have worked with TypeORM extensively and typically this is because the code is expecting Javascript / the project needs to be run with ts-node. But this happens even when running npm run start after running npm run build and all of the TS should be JS at that point.

A zip of my project is attached.

@dgurns It seems to me that babel config is not correctly loaded. Issue arise from babel-decorator anyway, so it should be better to ask them
