I was trying to add winston logger to the project, but getting these errors:

I have already tried adding node: { fs: 'empty' } in webpack config file and also tried target: 'node' . It's not working.
In my case I was importing winston in a browser environment and winston does not support browser environment yet.

I have some errors with webpack 5, express, github actions.
I use the github actions because want to use github secrets.
also, I use webpack because of using the secrets in the code.
anyway, I got errors below,

Also, got 15 warnings. if you want to the warnings, let me know.
what is the problem?
Below is the webpack.config.js
const webpack = require("webpack");
module.exports = {
target: "async-node",
mode: "production",
entry: "./app.js",
output: {
path: "/dist",
filename: "main.js",
},
plugins: [
new webpack.DefinePlugin({
"process.env.PA_URL": JSON.stringify(process.env.PA_URL),
"process.env.PA5_EMAIL": JSON.stringify(process.env.PA5_EMAIL),
"process.env.PA5_PASSWORD": JSON.stringify(process.env.PA5_PASSWORD),
}),
],
};
the webpack version is wrong?
You are bundling your entry file, but also any node_modules your ./app.js requires, which in turn tries to require a bunch of third-party stuff, which is not available - hence the errors on missing modules.
Exclude those node_modules by extending your webpack config:
yarn add -D webpack-node-externals
(see: https://www.npmjs.com/package/webpack-node-externals)
const webpack = require("webpack");
const nodeExternals = require("webpack-node-externals");
module.exports = {
target: "async-node",
mode: "production",
entry: "./app.js",
externalsPresets: { node: true }, // <-- here
externals: [nodeExternals()], // <-- and here
...etc
That should exclude them and you should be good to go.
I'm trying to use gRPC with javascript. I want to use the gRPC package, as I need to send some metadata, but I get an error when I'm using require('grpc').

The problems shows when I use this line: var grpc = required('grpc') and this command: npx webpack <file>.
Here's package.json file:
{
"name": "example",
"version": "0.1.0",
"description": "example",
"devDependencies": {
"#grpc/proto-loader": "^0.3.0",
"google-protobuf": "^3.6.1",
"grpc": "^1.24.4",
"grpc-web": "^1.0.0",
"webpack": "^4.16.5",
"webpack-cli": "^3.1.0"
}
}
I'm not really familiar with node.js, so it would be great if someone could explain it to me.
Thanks in advance for help!
I have created a PCF (Powerapps Component Framework) in which I am using the GEOCODE feature. I have installed the required components using "npm install node-geocoder" and have added the below code :
let nodeGeocoder = require('node-geocoder');
let options = {
provider: 'openstreetmap'
};
let geoCoder = nodeGeocoder(options);
geoCoder.geocode('Luray Caverns')
.then((res)=> {
console.log(res[0].latitude);
console.log(res[0].longitude);
})
.catch((err)=> {
console.log(err);
});
When i build this code using "npm run build", the build fails with following error:
ERROR in ./node_modules/request/lib/har.js
Module not found: Error: Can't resolve 'fs' in 'D:\PCF\Demo\node_modules\request\lib'

Any help would be helpful.

It was a node application. Added a following node in webpack config solved my issue
target:'node',
I refereed the article at https://jlongster.com/Backend-Apps-with-Webpack--Part-I
Simply add this to your webpack config file:
const webpackConfig = {
target: 'node'
};
module.exports = webpackConfig;
I have followed below steps Source from https://github.com/jkuri/ng2-slimscroll
Installation
npm install ng2-slimscroll
Imported module like
import { SlimScrollModule } from 'ng2-slimscroll';
imports: [ ....................,
