So, I am working with TypeORM and am getting an odd error when I transpile my TypeScript to JavaScript. I am receiving the following error:
(function (exports, require, module, __filename, __dirname) { import { Entity, PrimaryGeneratedColumn, ManyToOne, OneToMany, TreeChildren, TreeParent, JoinColumn, Column, Tree, TreeLevelColumn } from "typeorm";
^^^^^^

The file throwing the error:
import { Entity, PrimaryGeneratedColumn, ManyToOne, OneToMany, TreeChildren, TreeParent, JoinColumn, Column, Tree, TreeLevelColumn } from "typeorm";
import { User } from "./User";
import { Debate } from "./Debate";
@Entity()
@Tree("closure-table")
export class Comment {
@PrimaryGeneratedColumn("uuid")
id: string;
@Column()
text: string;
@ManyToOne(type => User)
user: User;
@ManyToOne(type => Debate, debate => debate.comments)
debate: Debate;
@TreeChildren()
children: Comment[];
@TreeParent()
parent: Comment;
}
What I have tried:
import (lib) from (module)
to const (lib) require (module)";
However, this causes more issues and doesn't work well.I have been googling for this issue extensively and it has left me scratching my head. Any and all help would be greatly appreciated.
Alright, I am simply dumb.
So, the ormconfig.json points your entities to your ts files in your /src folder. When you build your project, it should point to where your entities are. I did think it was odd that it was trying to reference a TS file after building.
ormconfig.json
{
"type": "postgres",
"host": "**********************",
"port": 5432,
"username": "**************",
"password": "*************",
"database": "*************",
"synchronize": true,
"logging": false,
"entities": [
// changed this
"dist/entity/*.js"
],
"migrations": [
"src/migration/**/*.ts"
],
"subscribers": [
"src/subscriber/**/*.ts"
],
"cli": {
"entitiesDir": "src/entity",
"migrationsDir": "src/migration",
"subscribersDir": "src/subscriber"
}
}
