Told you before, it just cant find the dll

untold osprey
#

the path is correct

wanton oracle
#

Is there a specific location where it finds the dll from?

untold osprey
#

yes

wanton oracle
#

In your inventory api are you calling a load function?

#

I really think that path variable is messing things up

#

Try printing the path variable to see if its correct before loading

untold osprey
#

it do not work also if i put manually the path

wanton oracle
#

Very weird. If its working for one script it should work for the others too.

#

Anything related to loading or anything in inventory api ?

untold osprey
#

im my api i import it w this
import { TLS_Client } from '@/utils/tls/tls';
and in my other script i use the same import

#

it's 100% that in next it's not viewing the dll file

#

but idk why

wanton oracle
#

Try using the public folder then ig

wanton oracle

The problem is related to webpack loader for .node file, atm my config is this but i'm getting this error: Conflict: Multiple assets emit different content to the same filename koffi.node

import os from 'os';

export default {
    reactStrictMode: false,
    env: {
        BASE_URL: process.env.BASE_URL,
    },
    webpack: (config, { dev, isServer, webpack, nextRuntime }) => {
        // Trova la regola esistente per i file .node, se presente
        const existingNodeRule = config.module.rules.find((rule) =>
            rule.test instanceof RegExp && /\.node$/.test(rule.test.source)
        );
        console.log(existingNodeRule);

        if (existingNodeRule) {
            console.log("n");
            // Modifica la regola esistente invece di aggiungerne una nuova
            existingNodeRule.use.push({
                loader: "nextjs-node-loader",
                options: {
                    flags: os.constants.dlopen.RTLD_NOW,
                    outputPath: config.output.path,
                },
            });
        } else {
            console.log("y");

            // Se non esiste una regola esistente, crea una nuova regola
            config.module.rules.push({
                test: /\.node$/,
                use: [
                    {
                        loader: "nextjs-node-loader",
                        options: {
                            flags: os.constants.dlopen.RTLD_NOW,
                            outputPath: config.output.path,
                        },
                    },
                ],
            });
        }

        return config;
    },
};

i made the solution by mysef, i used koffi because have more stable relases than ffi napi, the problem was that the webpack was not able to solve the ffi napi lib because there was not a compatible version, and using nextjs-node-loader i was able to use .node relases in next
file:next.config.js

import os from 'os';
import path from 'path';
import { fileURLToPath } from 'url';
const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);
const arch = os.arch()
const platform = os.platform()
export default {
    reactStrictMode: false,
    env: {
        BASE_URL: process.env.BASE_URL,
    },
    webpack: (config, { dev, isServer, webpack, nextRuntime }) => {
        // Trova la regola esistente per i file .node, se presente
        config.resolve.alias.koffi = path.resolve(`node_modules/koffi/build/koffi/${platform}_${arch}/koffi.node`)
        config.module.rules.push({
            test: /\.node$/,
            use: [
                {
                    loader: "nextjs-node-loader",
                    options: {
                        flags: os.constants.dlopen.RTLD_NOW,
                        outputPath: config.output.path
                    },
                },
            ],
        });

        return config;
    },
};
