Automatically import module

[michaelmesser]

Automatically import modules.
A.ts:

export const a = 2

B.ts:

const b = a + 2

Module B would automatically import module A.

What do you mean exactly by automatically? Is this a language-service related quick-fix? Or is it something the compiler would figure out on its own?

[michaelmesser]

I mean the compiler

[mhegazy]

The compiler can not implicitly figure out your imports. what if you have a global called a, what if you have multiple modules called a, what if it is just an error..
Modules do have a clear syntax for importing names into their scope.

If there any way to avoid importing 10 files at the top of every file?

import X from "./X.ts"
import Y from "./Y.ts"
...

Or to import a file/library project wide?

[mhegazy]

you could reexport declarations.. e.g.:

// api.ts

// Things that every one needs
export * from "./x";
export * from "./y";
export * from "./z";

// module.ts

import { x, y, z} from "./api";

@mhegazy Thanks for your help. That work around will do. I was hoping for something like swift thought were imports happen automatically for the same project.

[michaelmesser]

Is there a way to do import * from "./file.ts"?

[kitsonk]

import * as file from "./file.ts";

StackOverflow or gitter or ##typescript on IRC are really good places for these types of questions.

As @kitsonk noted, import * as ns from "mod" is the recommended pattern. You can find more about what import * from "mod" was not considered in #2956 (comment)
