How Can I Generate a Tsconfig. Json File?

For those who have TypeScript installed as a local package (and possibly as a dev dependency) via:

$ npm install typescript --save-dev

...and who have added tsc script to package.json:

"scripts": {
   ...
   "tsc": "tsc"
},

You can call tsc --init via npm:

$ npm run tsc -- --init 

If you don't want to install Typescript globally (which makes sense to me, so you don't need to update it constantly), you can use npx:

npx -p typescript tsc --init

The key point is using the -p flag to inform npx that the tsc binary belongs to the typescript package

You need to have typescript library installed and then you can use

npx tsc --init 

If the response is error TS5023: Unknown compiler option 'init'. that means the library is not installed

yarn add --dev typescript

or for npm

npm i --save-dev typescript

and run npx command again

I recommend not to install dependencies globally as it is easier to manage the versioning for each project. It is also easier for coworkers to see an install what is needed to run the project with one command.

this worked for me:

tsc --init

Setup a ts project as following steps:

• install typescript yarn global add typescript
• create a package.json: run yarn init or setting defaults yarn init -yp
• create a tsconfig.json: run tsc --init
• (*optional) add tslint.json

The project structure seems like:

│  package.json
│  tsconfig.json
│  tslint.json
│  yarn.lock
│
├─dist
│      index.js
│
└─src
       index.ts

install TypeScript :

npm install typescript

add tsc script to package.json:

"scripts": {
  "tsc": "tsc"
 },

run this:

npx tsc --init

i am using this,

yarn tsc --init

this fixed it for me

$ npm run tsc -- --init
This worked for the below package.json

  "devDependencies": {
    "@types/jasmine": "^3.6.2",
    "@types/node": "^14.14.19",
    "jasmine": "^3.6.3",
    "protractor": "^7.0.0",
    "typescript": "^4.1.3"
  },

I recommend to uninstall typescript first with the command:

npm uninstall -g typescript

then use the chocolatey package in order to run:

choco install typescript

in PowerShell.

From 2ality. You can add a function in your .zshrc or .bashrc to shortcut to the local bin path.

# in .zshrc:
function npm-do { (PATH=$(npm bin):$PATH; eval $@;) }

# working inside your directory:
npm-do tsc --init

the Normal way to generate the tsconfig file is to create a file with a name tsconfig.json then open {} ,inside this {} hit

ctrl + spacebar ( Windows)

cmd + spacebar (mac)

then choose compilationOptions then choose what options you need

For auto-generation (tsconfig.json) using VSCode terminal or any cmd on the same directory you wanna create :

tsc --init
