- Start a project
npm init
- install typescript
-
npm install --global typescript
this will install tsc as a global command.
-
npm install --save-dev typescript
this will add to package.json and in the code’s node_modules folder but tsc will not be available in the shell
- to verify install,
tsc -v
will give you the version of typescript compiler
-
- Add REACT to the project
npm install react react-dom npm install --save-dev @types/react @types/react-dom
- Note that -i is shorthand for install and -D is shorthand for –save-dev
- One can use
npm uninstall (package name)
to undo an install
- To run a typescript file directly, not through the browser (i.e. not a web page)
npm install --global ts-node
