ReferenceError: exports is not defined in ES module scope

I am trying to run my bot and am presented with the following error

This file is being treated as an ES module because it has a '.js' file extension and '/home/demonicpagan/development/nodejs/discordBots/discord-trakt/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

What do I need to do to resolve this?

Since there are so many files involved and the length would exceed the Discord limitations, I created a gist with everything I think is needed.

ReferenceError: exports is not defined in ES module scope

ReferenceError: exports is not defined in ES module scope - TraktClient.ts

Solution

so when using pnpm you need to hoist all of

@sapphire/*

@sapphire/*

because otherwise TS cannot properly resolve module augmentations. I forgot the exact option but it's one of the hoist pattern options.

As for your root cause, it really comes down to how you configured tsconfig. The modern standard is to use

node16

node16

for both

module

module

and

moduleResolution

moduleResolution

then either use

"type": "commonjs"

"type": "commonjs"

"type": "module"

"type": "module"

in your package.json based on whether you respectively want a CJS or ESM runtime.

Once that is done and you compile with either exclusively swc (which you seem to use yet you also mention ts-node, they DO NOT work together, also we discussed the downsides of ts-node) or alternatives such as

tsc

tsc

tsc-watch

tsc-watch

tsup

tsup

.

The error in particular suggests that you compiled for CJS but are running as ESM (i.e. you specified

"type": "module"

"type": "module"

in your package.json) which causes the error of

exports

exports

not being defined in an ES module (ESM) scope. So either change your compilation to ESM, or change

"type": "module"

"type": "module"

to "

type": "commonjs

type": "commonjs
