I am trying to use node for the first time,installed node.js below is the information
node -v
v14.4.0
npm -v
6.14.5
Completed the setup by creating a package.json file, then tried to install lite-server using the command
npm install lite-server --save-dev produced the folllowing error:
npm WARN deprecated chokidar#2.1.8: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.

But still I get the same error. Can anyone help me with this?
Thank you, in advance.

you are missing the dependency on lite-server
try to install lite-server dependency
npm install lite-server --save-dev
then invoke npm run lite

"concurrently command not found" but installed gloabally

I'm using macOs and even though concurrently is installed globally through npm, when setting it as a start script in package.json and typing npm start the following error occurs.
concurrently - kill-others "npm run server" "npm run client"
sh: concurrently - kill-others: command not found

You need to install the dependency locally in order to use it in any of your start scripts. run
npm install --save concurrently
to install it locally in your project

Your error is not with the package itself, you can either have it globally or save it locally (not --save-dev).
You can find the solution for your problem looking at the error log
concurrently - kill-others "npm run server" "npm run client"
sh: concurrently - kill-others: command not found
The command should be either --kill-others or -k for short, here is the official documentation: https://github.com/kimmobrunfeldt/concurrently
Try this as your package.json
{
"name": "thesis_fullstack",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"client": "cd client && npm start",
"server": "cd server && npm start",
"start": "concurrently --kill-others \"npm run server\" \"npm run client\""
},
"keywords": [],

"dependencies": {
"concurrently": "3.5.1"
}
}
Cheers :)

I seriously don't know what I did to fix it. First of all i fixed the command flag "typo" to concurrently --kill-others your_commands_here. Then i uninstalled node manually and reinstalled it through Homebrew (since I'm using MacOs). After that node and npm wouldn't work at all. Fixed it with: https://stackoverflow.com/a/54583099/13212764. I think by that point running npm start worked.

For
Globally -
npm install -g concurrently
Locally -
npm install concurrently

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'.

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",

"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\""

Error while installing npm install grunt-contrib-clean --dev-save

Having this package.json file, while installing npm install grunt-contrib-clean --dev-save I am getting below error.

Your package.json file doesn't parse because you're missing a comma at the end of
"grunt": "^0.4.5"
Also, the option is --save-dev not --dev-save.
