The companyName variable cannot be accessed outside this Employee module, as it is not exported. Import. A module can be used in another module using an import statement. I am very new to WebStorm, on a trial. I create a trivial TypeScript file which runs fine, but the word Map is in red and says TS2304: Cannot find name 'Map'.

Dec 15, 2016 · The compiler does not rewrite module names. module names are "resource identifiers" and the compiler does not touch them, just like your string literals. all what baseUrl and paths do is tell the compiler where to find the .d.ts for this module, but no changes to the output are caused by these options.

Sure, if the people wants to run TS code directly via ts-node is dividab/tsconfig-paths an alternative . I use it for development. My solution is pretty simple: replace TS path aliases using a tsconfig.json as well. But replacing those paths directly into the .js files, not on the fly like tsconfig-paths for example.

We could define each module in its own .d.ts file with top-level export declarations, but it’s more convenient to write them as one larger .d.ts file. To do so, we use a construct similar to ambient namespaces, but we use the module keyword and the quoted name of the module which will be available to a later import. In Angular, the best practice is to load and configure the router in a separate, top-level module that is dedicated to routing and imported by the root AppModule. By convention, the module class name is AppRoutingModule and it belongs in the app-routing.module.ts in the src/app folder. Use the CLI to generate it.

Apr 29, 2016 · import {map, groupBy, flatMap, keys, filter, find } from "lodash"; While this takes some time to convert, you get the advantage of much smaller Javascript files when bundled, because your tooling (e.g. webpack) will remove functions you aren’t using.
