This is a Bug Report

I created an stackoverflow question for the same, i’m pasting the full content from there.

The stackoverflow link: https://stackoverflow.com/questions/50188865/load-native-npm-x509-package-using-webpack-in-serverless

I’m testing the aws iot features using serverless framework. So for one usecase I wasn’t to analyse the x509 certificates iot devices register with aws from aws lambdas, I saw npm package named x509 to do it easily. It’s a native package, so I’m building it in Ubuntu 64 bit box to make it compatible with aws environment.

Issues is the webpack is not identifying this npm package even after my package importing it.

The error it saying is,

$ sls package

     OS:                     linux
     Node Version:           8.10.0
     Serverless Version:     1.26.1

My package dir structure is,

- myproject
-- webpack.config.js
-- serverless.yml
-- jitr
--- index.js <- Here I'm importing x509
--- node_modules
---- x509
----- index.js <- First line: var x509 = require('./build/Release/x509')
----- build/Release/x509.node

My webpack config file

const path = require("path");
const slsw = require("serverless-webpack");
const nodeExternals = require("webpack-node-externals");
const CopyWebpackPlugin = require("copy-webpack-plugin");

module.exports = {
    entry: slsw.lib.entries,
    target: "node",
    output: {
        libraryTarget: "commonjs2",
        path: path.resolve(__dirname, ".webpack"),
        filename: "[name].js"
    },
    module: {
        rules: [
            {
                test: /\.json$/,
                loader: "json-loader"
            },
            {
                test: /\.node$/,
                loader: "node-loader"
            }
        ]
    },
    mode: "none",
    externals: [
        nodeExternals({
            whitelist: ["x509"]
        })
    ],
    plugins: [
        new CopyWebpackPlugin([
            {
                from: "jitr/node_modules/x509/build/Release/x509.node",
                to: "jitr/build/Release/x509.node",
                toType: "file"
            }
        ])
    ]
};

What might be going wrong here ?. I was looking for more debugging steps when doing webpack command, but here i’m using a serverless plugin named serverless-webpack to package and deploy the lambdas.

Aws lambda have access to raw openssl command, if nothing works I have to use that command from nodejs to do the things.
