I am trying out TypeScript on Node.js.
I have installed it using
npm install typescript
When just run tsc:
:~$ tsc
Version 1.0.1.0
Syntax: tsc [options] [file ..]
So, I am trying to run simple code:
console.log('test');
which is not outputing nothing.
How can I output anyting in console from typescript running on node.js?
tsc is a compiler not a repl.
You need to write your typescript , compile it with tsc then execute it with nodejs.
tsc test.ts | node test.js and have it executed immediately. Thanks.
tsc test.ts && node test.js
With ts-node, which is a TypeScript execution environment, you can now execute TypeScript with node as you expected from the tsc compiler.
After installing ts-node you can run your example directly as
ts-node -e 'console.log("test")'
or you can run a TypeScript file as:
ts-node script.ts
Please find further details on the ts-node npm page
You need to install this dev depending
npm i -D @types/node
After writing
> console.log('test');
Save this by example as test.ts
then run the command tsc test.ts (this will compile your code to JS) you will see a new file created by tsc with the name test.js
Now you can run your test by typing: node test.js.
