Running the command node dist/index.js gives an error related to Typescript files in src folder

November 30, 2021, at 01:10 AM

I have a GraphQL and Apollo server https://github.com/AdhamAH/Film-and-actors-list/tree/main/server

After running tsc -p . then node dist/index.js I am getting the error from a TS file in the src folder like this

Film-and-actors-list\server\src\entities\Films.ts:1
import {Field, ObjectType} from "type-graphql";
^^^^^^
SyntaxError: Cannot use import statement outside a module

After searching for hours with no luck I had an idea to delete the src folder and when I run node dist/index.js the server starts with no error

I tried to change the tsconfig.jsonoptions but no luck

My tsconfig

{
  "compilerOptions": {
    "target": "es2017",
    "module": "commonjs",
    "lib": ["dom", "es6", "es2017", "esnext"],
    "skipLibCheck": true,
    "sourceMap": true,
    "outDir": "./dist",
    "moduleResolution": "node",
    "removeComments": true,
    "noImplicitAny": true,
    "strictNullChecks": true,
    "strictFunctionTypes": true,
    "noImplicitThis": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitReturns": true,

    "experimentalDecorators": true,
    "resolveJsonModule": true,
    "baseUrl": "."
  },
  "exclude": ["node_modules"],
  "include": ["./src/**/*.ts"]
}

And my package.json:

Answer 1

I figured it out

The problem was that I had a file ormconfig.json with following

{
  "type": "sqlite",
  "database": "./db.sqlite3",
  "entities": ["./src/entities/*.ts"],
  "synchronize": true
}

So it looks like that when I start the server it is loading the TS files from entities folder

What I did that I added this configuration to index.ts like this

const connection = await createConnection({
      "type": "sqlite",
      "database": "./db.sqlite3",
      "entities": [User, Films],
      "synchronize": true
  })

With this I imported the entities and solved the problem
