Import JSON inside NPM Module

I made an npm module, this module export a function that load a json file and then export the result ( a little bit simplified )

The probleme is when I import this module inside another project I have this error :

 no such file or directory, open 'C:Users{my_username}github{name_of_the_project}file.json'

I looks like when I import my module, it try to read the json inside the current directory and not inside the npm module.

The code inside my module :

export default function() {
    return readFile('./swagger.json')
        .then(data => JSON.parse(data))
}

Final answer (for ES Module) :

import { readFile } from 'fs/promises';
import { fileURLToPath } from 'url';
import path from 'path';

export default function() {
    const __filename = fileURLToPath(import.meta.url);
    const __dirname = path.dirname(__filename);

    return readFile(`${__dirname}/swagger.json`)
        .then(data => JSON.parse(data))
}

If you don’t use ES Module (but commonJS), __dirname already exist so you can do :

export default function() {
        return readFile(`${__dirname}/swagger.json`)
            .then(data => JSON.parse(data))
    }
