I'm trying to figure out why I'm getting this pesky bug: SyntaxError: Cannot use import statement outside a module I'm using discord.js and typescript to create a discord bot. I'm currently creating my own command handler by dynamically importing all files in a commands dir. However, whenever I import such file Code at question:

Promise.all((await getCommands("private")).map(async absPath => {
            return { name : basename(absPath), mod:  ( await import(absPath)).mod as fdjsMod  }
         })).then( modArr => {
             for ( const { name, mod } of modArr) {
                 publicMap.set(name.substring(0, name.length-3), mod)
             }
             
        })

import { Result, Err, Ok } from 'ts-results';

//^^^^^^^^^^ Cannot use import statement outside a module

import * as Handler from "../../types/index"

export default {
        alias: ["p"],
        type: Handler.CommandType.TEXT,
        delegate : () => {
            return Err("pong")
        }
} as Handler.fdjsMod

my tsconfig :

    "resolveJsonModule": true,
    "outDir": "dist",
    "rootDir": "src"

  },

Things I have tried :

1. Setting type to module in my package.json

• this only leads to an error saying exports is not defined in ES module scope

2. Change dist folder js output to .cjs files

• same error

3. Switch between cjs require() and dynamic import() -same error

Any and all help would be appreciated.

Try adding these attributes to your tsconfig:

{
  "compilerOptions": {
    "resolveJsonModule": true,
    "outDir": "dist",
    "rootDir": "src",
    "module": "commonjs",
    "moduleResolution": "node",
    "esModuleInterop": true,
  },
  "extends": "@tsconfig/node16/tsconfig.json"
}

I'm not sure if this works for you, but it did for me.

Solved : when i was dynamically importing files from my command folder, i was directing it to my src file instead of dist :

export default async function getCommands(type: privOrPub) : Promise<string[]> {
    //src/commands/public
    const publicCommands = join(process.cwd(), "src/commands/public")
    const privateCommands = join(process.cwd(), "src/commands/private")

    return type == 'private' ? readPath(privateCommands) : readPath(publicCommands)
}

export default async function getCommands(type: privOrPub) : Promise<string[]> {
    //src/commands/public -> dist/commands/public
    const publicCommands = join(process.cwd(), "dist/commands/public")
    const privateCommands = join(process.cwd(), "dist/commands/private")

    return type == 'private' ? readPath(privateCommands) : readPath(publicCommands)
}

Thanks for the help, everyone. I didnt expect the error to be so trivial
