Setting to set execution environnement (node or browser)

[testerez]

When coding for node, It feels strange to have all the stuff specific to browser available by default.
For example, this is compiled with no warning by tsc 2.0.2:

alert(name); // name and alert are part of lib.d.ts

Maybe an env setting in tsconfig.json could be a solution...
And I would also appreciate that tsc --init interactively ask for it. Like eslint --init does for example.

You can set e.g. "lib": ["es2015.core"] in your tsconfig's compilerOptions settings:

Why is the browser environment opt-out, but other environments (like node) are opt-in?

[testerez]

Yes it's working thanks. But now, console cannot be found.
99.9% users will run the javascript code either inside the browser or node.
Don't you think that it would make sense to have simple presets to support those environments ?

@testerez re getting things like console to work, @RyanCavanaugh's suggestion above doesn't cover that. You also need the node typings. See #9466 (comment). I think the step 3 there is no longer needed due to a recent fix.

I get this error

error TS2318: Cannot find global type 'Boolean'.
error TS2318: Cannot find global type 'IArguments'.
error TS2318: Cannot find global type 'Number'.

tsconfig.json

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es5",
    "noImplicitAny": true,
    "sourceMap": false,
    "strictNullChecks": true,
    "lib": [
      "es2015.core"
    ],
    "types": ["node"]
  }
}

and running
tsc -p tsconfig.json

@testerez try using "lib": ["es2015"] instead of "lib: ["es2015.core"].

[testerez]

Ho yes sorry didn't see the difference here. Working now!
So what about the interactive tsc --init is there any plan about something like that?

It's not so easy to sell typescript to JS devs... Anything that could make the first contact smoother is welcome!

[yortus]

Personally I agree that typeScript should not 'choose favourites' between environments.

Maybe you could chime in on #9466 since that covers much the same concern and is labeled 'awaiting more feedback'.

[testerez]

Yes, same topic. Thanks for the link.

adding a lib for node is covered in #9466. closing.
