Unable to run

[S3j5b0]

Hi, I've been trying to run the program as shown in the course.

I first ran it with the dependencies in the versions they are here on this repo.
But When time came to run the application, this error showed up:

[webpack-cli] Unable to load '@webpack-cli/serve' command
[webpack-cli] TypeError: options.forEach is not a function
    at WebpackCLI.makeCommand (C:\Git\TypeScript-Getting-Started\node_modules\webpack-cli\lib\webpack-cli.js:108:21)

I did'nt know what this meant, but the dependencies were quite old, so I figured updating them could make sense.And they now look like this:

  "devDependencies": {
    "ts-loader": "9.4.1",
    "typescript": "4.8.4",
    "webpack": "5.74.0",
    "webpack-cli": "4.10.0",
    "webpack-dev-server": "4.11.1"
  }

I then ran npm install, tsc app\app.ts and npm start.
This does start the application like this:

> npm start   

> multimath@4.0.0 start
> webpack serve

But, when I now try to access http://localhost:8080/ in the browser, this is the only thing I get:

Cannot GET /

Wat is wrong?

It might be because you updated webpack-dev-server and ts-loader to new major versions, which likely have breaking changes.

This is the output of npm outdated with the repo in its current state:

Package             Current  Wanted  Latest  Location                         Depended by
ts-loader            8.0.17  8.0.17   9.4.1  node_modules/ts-loader           TypeScript-Getting-Started
typescript            4.2.2   4.2.2   4.8.4  node_modules/typescript          TypeScript-Getting-Started
webpack              5.22.0  5.22.0  5.74.0  node_modules/webpack             TypeScript-Getting-Started
webpack-cli           4.5.0   4.5.0  4.10.0  node_modules/webpack-cli         TypeScript-Getting-Started
webpack-dev-server   3.11.2  3.11.2  4.11.1  node_modules/webpack-dev-server  TypeScript-Getting-Started

I was able to clone the repo, npm install and npm start to see the app running at localhost:8080 without modifications.

After battling with this for a couple of hours this morning, I found the solution which is to only update webpack-cli to 4.10.0 and leave the rest the same. My devDependencies config looks like this now:

  "devDependencies": {
    "ts-loader": "8.0.17",
    "typescript": "4.2.2",
    "webpack": "5.22.0",
    "webpack-cli": "4.10.0",
    "webpack-dev-server": "3.11.2"
  }

Hope this helps anyone else stumbling on this issue.

When running I was having this webpack error:
{
opensslErrorStack: [ 'error:03000086:digital envelope routines::initialization error' ],
library: 'digital envelope routines',
reason: 'unsupported',
code: 'ERR_OSSL_EVP_UNSUPPORTED'
}

This solved the issue:
"scripts": {
"start": "SET NODE_OPTIONS=--openssl-legacy-provider && webpack serve"
},

I believe this PR will resolve the errors folks are seeing #39
