How can I generate a tsconfig.json file?

Question

How can I generate a tsconfig.json via the command line? I tried command tsc init, but this doesn\'t work.

Answer 1

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 

Answer 2

install TypeScript :

npm install typescript

add tsc script to package.json:

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

run this:

npx tsc --init

Answer 3

i am using this,

yarn tsc --init

this fixed it for me

Answer 4

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

and run npx command again

Answer 5

this worked for me:

tsc --init

Answer 6

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
