Package.json -> type: "module" -- not supported

[kingmesal]

I recently needed to add type:"module" to my package.json and setup my modules: "ESNext". This has caused joi-to-typescript to break with the following error.

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /scripts/makeTypes.ts
    at new NodeError (node:internal/errors:372:5)
    at Object.getFileProtocolModuleFormat [as file:] (node:internal/modules/esm/get_format:56:11)

    at ESMLoader.getModuleJob (node:internal/modules/esm/loader:304:34)
    at async Promise.all (index 0) {
  code: 'ERR_UNKNOWN_FILE_EXTENSION'
}

Now, if I add this to my tsconfig.json:

    "ts-node": {
        "compilerOptions": {
            "module": "CommonJS"
        }
    },

and remove type: "module" from package.json

While I can clearly remove / readd the type module to my package.json, I was wondering if there is a build target fix that would resolve this... e.g. not commonjs module.

Any thoughts?

its sounding like I should drop commonjs module and just go esm

Hi, I just wanted to ask if there was an update on this. I would really like to use this package, but I have to use esm. So changing back to cjs is not an option for me.

Is there any way to help you with this?

[mrjono1]

yes, if you have time to create a PR to fix this that would be awesome

[luiskugel]

Ok, I just have to get a release out the next week. When that is done in about 2 weeks, I will make the pull request.

I have already forked and implemented it, just have to make it nice and create the pull request.

[mrjono1]

awesome thankyou, there will be many people thanking you

Im happy for this project to move to esm only

Any news about this ? I have same problem on my project I moved to full ESM.

This is my joiToTypescript.ts config file :

import joiToTS from 'joi-to-typescript';

const types = async (): Promise<void> => {
    // eslint-disable-next-line no-console
    console.log('Running joi-to-typescript...');

    // Configure your settings here
    const result = await joiToTS.convertFromDirectory({
        schemaDirectory     : './src/schemas',
        typeOutputDirectory : './src/types',
        debug               : true,
        indexAllToRoot      : false,
        ignoreFiles         : [
            'index.ts',
        ],
    });

    if (result) {
        // eslint-disable-next-line no-console
        console.log('Completed joi-to-typescript');
    } else {
        // eslint-disable-next-line no-console
        console.log('Failed to run joi-to-typescript');
    }
};

types();

When I launch it in node 20 using node --loader ts-node/esm ../../commonConfiguration/joiToTypescript.t, I have this error :

(node:29354) ExperimentalWarning: `--experimental-loader` may be removed in the future; instead use `register()`:
