TypeScript / JavaScript - import all types

javascript typescript import ecmascript-6

With ES6 modules, the closest thing available to what you want is a namespace import:

import * as foo from './otherClass';

The use it individual exports as

foo.ClassA

You can see the available kinds of imports in the import documentation.

Also, what's the meaning of the { ... } and some of the types being outside and some inside?

That's for importing named exports. You can read about that in the documentation I referenced or in my answer here.

javascript typescript import ecmascript-6

You can use triple slashes import:

/// <reference path="./actionsCollection.ts" />

They must have to be the on the first line(s) of the file.
