ESM import error

trafficstars

Running one of the below

// dev.mjs
import { watch } from 'turbowatch';

// OR dev.cjs
const { watch } = require('turbowatch');

produces

const zx_1 = require("zx");

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/staffan/dev/lr2/node_modules/zx/build/index.js from /Users/staffan/dev/lr2/node_modules/turbowatch/dist/createSpawn.js not supported.
...

Expected Behavior

It should work to import the library

Possible Solution

Publish turbowatch as ESM. Possibly you could consider hybrid, but it seems zx is ESM only (due to node-fetch?), as well as serialize-error

Or am I missing something?

[gajus]

Can you try running turbowatch ./dev.mjs?

[gajus]

Closing as there is no answer and I cannot replicate this.

[staeke]

You didn't give me a lot of time there :)

Anyhow, that does indeed work. As does renaming .mjs to .ts and running node -r jiti/register dev.ts. Maybe make that clearer in docs?

[NickHeiner]

I'm running into this same issue, but I'm not sure what the fix is. What's ./dev.mjs?

[gajus]

@NickHeiner Just do turbowatch your-script.ts

[NickHeiner]

I'm using turbowatch programmatically.

My goal is to detect when files in a directory change, then take action via the event emitter.

[gajus]

@NickHeiner In that case, you will need to either adopt esm or use something like node --loader tsx your-script.ts

Hey @gajus, do you mind taking a look at this bare minimum repo where the error can be reproduced?

There is only a single package.json script called dev. Running it would produce this error:

> node --loader tsx turbowatch.ts

Node.js v20.3.1

Not exactly sure what is causing this, a week or so ago everything was working, but unfortunately I am still early in development and wasn't keeping history.

As you can see I'm using Node 20 with package.json of type: module. Any idea what might be causing this or a tip how to fix it?

Cheers!

I'm seeing the same issue as @virtuallyunknown just by copying the example from the docs. Same issue with node 18 as well. Is there any example somewhere of it working?

It is not an issue if you are using turbowatch binary.

[virtuallyunknown]

I was previously using node --loader tsx turbowatch.ts because for some reason when you use the turbowatch binary you have to ctrl+c twice to terminate the process, the first time it does nothing, only terminates after the second time.

This might sound like a very silly thing to complain about, but when you're developing and restarting your monorepo all day long it becomes annoying.

I am also facing same issue like above.

I was previously using node --loader tsx turbowatch.ts because for some reason when you use the turbowatch binary you have to ctrl+c twice to terminate the process, the first time it does nothing, only terminates after the second time.

That's a graceful termination feature.

The first time you send a signal with ctrl+c it initiates graceful termination and waits for all services to shutdown.

If you don't wait and press again, then you force terminate all scripts.

Any way to disable this? I am only using turbowatch in development, data loss and whatever else graceful termination prevents is not a risk for me.

I cannot imagine a scenario where this is desirable. You will be leaving hanging services left and right.

If you want your services to shutdown immediately, then add the logic to the application itself to shutdown immediately (when in NODE_ENV=development).

[virtuallyunknown]

You said that the first signal is graceful termination, and the second signal is forceful termination. So I was asking if there is a way I can instead configure the first signal to be the forceful termination.

[AlexAegis]

I had the same

const zx_1 = require("zx");
             ^

Error [ERR_REQUIRE_ESM]: require() of ES Module

error earlier too, I made a package to host my turbowatch configuration, originally I had the watch fn call inside it and that resulted in this error. (I'm using "type": "module", vite for bundling) I removed all actual imports from turbowatch and kept only type imports, and now it's working.

The package for reference (It's very far from a lightweight reproduction, I didn't mean it as such): https://github.com/AlexAegis/js-tooling/blob/34f65bf2332d4524f81c559848c8f3a9f9071cb2/packages/turbowatch/src/internal/watch-local-node-modules.ts

On a sidenote, I have a very nice and functional setup with the above configuration, thank you very much for this project!

[gajus]

You could, but depending on what services you are running, there is no guarantee that it will shutdown all the services. I would not do it as a default as it is bound to cause more confusion than anything.

I am absolutely not asking you to make this the default behavior of turbowatch, that would be quite irresponsible of me since I don't know what complications would arise from that. I was merely asking if you could tell me how I can configure this for my own project.

Just hit this as well when trying to use turbowatch as a library in an ESM project.
