I am using webpack to build my app so I am getting the following error on command prompt:

Alternatively, run 'webpack(-cli) --help' for usage info.

My file structure webpack.conifg.js:

It looks to me like a spelling mistake, entry: './scr/js/index.js
try to change it to ./src/js/index.js

Unable to run dev

I am currently taking a course on Udemy and I am stuck, I am having a problem running script. When I run the command npm run dev, I get this error message:
npm ERR! code ELIFECYCLE
npm ERR! errno 2
npm ERR! forkify#1.0.0 dev: `webpack`
npm ERR! Exit status 2
npm ERR!

What would be wrong? This is my package.json code:
{
"name": "forkify",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"dev": "webpack",
"build": "webpack --mode production",
"start": "webpack-dev-server --mode development --open"
},

"devDependencies": {

"webpack": "^4.28.4",
"webpack-cli": "^3.2.1",
"webpack-dev-server": "^3.1.14"
},
"dependencies": {
"babel-polyfill": "^6.26.0"
}
}
Here is the webpack.config.js code:
const path = require('path');
module.exports = {
entry: './src/js/index.js',
output: {
path: path.resolve(__dirname, 'dist/js'),
filename: 'bundle.js'
},
mode: 'development'
};
What could be wrong?
UPDATE: Some way I was able to finally npm run dev but it is being created in the wrong directory. How can I solve this?
I need it to appear under the starter > dist > js
Your path are not good replace entry: './src/js/index.js' by entry: './started/src/js/index.js'

How to run ts script with package.json?

I try to run typescript files with just a package.json file. So a minimum setup for running typescript files.
I just have a singel file: index.ts:
console.clear();
console.log("nic to see you!!");
and package.json file:
{
"name": "Todo",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node index.js"
},
"keywords": [],
"author": "",
"license": "ISC"
}
But if I try to do :
npm start, I will get this error:
Error: Cannot find module 'D:\Mijn Documents\UDEMY\TypeScript\Todo\index.js'

PS D:\Mijn Documents\UDEMY\TypeScript\Todo>
So my question is: what I have to change that it will compile?
Thank you
oke, I have it now like this:
packagege.json:
{
"name": "Todo",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build":"tsc -p ./src",
"start": "npm run build -- -w"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"ts-node": "^8.5.4",
"typescript": "^3.7.4"
}
}
And I installed typescript
and I do: npm start. I still get this error:
npm run build -- -w
> Todo#1.0.0 build D:\Mijn Documents\UDEMY\TypeScript\Todo
> tsc -p ./src "-w"
error TS5057: Cannot find a tsconfig.json file at the specified directory: './src'.

npm ERR! errno 1

oke, I have it now like this:
{
"name": "Todo",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "tsc main.ts dist/",
"start": "npm run build -- -w"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"ts-node": "^8.5.4",
"typescript": "^3.7.4"
}
}
and if I do this: npm run. I see this output:
> Todo#1.0.0 build D:\Mijn Documents\UDEMY\TypeScript\Todo
> tsc main.ts dist/ "-w"
[1:46:58 PM] Starting compilation in watch mode...
error TS6053: File 'dist/.ts' not found.
[1:46:59 PM] Found 1 error. Watching for file changes.
oke, I see now this:

> tsc -p ./ "-w"
[2:00:31 PM] Starting compilation in watch mode...
[2:00:34 PM] Found 0 errors. Watching for file changes.
But where I can see the results then? Will be nice to go to some port, like: localhost:4200 in the browser, but how to do that?
Try typing in the terminal as follows:
ts-node ./src/index.ts
Or, try the following modifications to the "start" script:
"start": "ts-node ./src/index.ts"
Thank you all!!
the trick was this in the package.json:
"start": "tsc-watch --onsuccess \"node dist/index.js\""

Running jshint via script produces NPM error: code ELIFECYCLE Exit status 2

Trying to run jsHint via script.
package.json:
{
"name": "projectName",
"version": "0.1.0",
"devDependencies": {
"jshint": "^2.9.1"
},
"scripts": {
"lint": "jshint src"
}
}
And get the following error:
npm ERR! Darwin 15.0.0
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "run" "lint"
npm ERR! node v4.2.4
npm ERR! npm v2.14.12
npm ERR! code ELIFECYCLE
npm ERR! projectName#0.1.0 lint: `jshint src`
npm ERR! Exit status 2
I resolved this adding "|| true" to the lint line of the script in my package.json file. See below:
{
"name": "projectName",
"version": "0.1.0",
"devDependencies": {
"jshint": "^2.9.1"
},
"scripts": {
"lint": "jshint src || true"
}
}
