file1.ts
namespace test { export class AA {} } file2.ts
/// <reference path="file1.ts" /> import * as express from "express"; // without this line it works namespace test { export class BB { constructor(a:AA){ var r = express.Router(); ... } } } If I comment the import line above, the code compiles but express import is missing. If I keep the import, I get
enter code hereerror TS2304: Cannot find name 'AA' Any idea how to fix this?
You are mixing so-called "internal" and "external" typescript modules (http://www.typescriptlang.org/Handbook#modules).
"import" keywoard tells compiler that you are using "external" approach. In this case
file1.ts - exports something
module test { export class AA {} } export = test; file2.ts - imports your test module
import * as express from "express"; // without this line it works import { AA } from "test" module test { export class BB { constructor(a:AA){ var r = express.Router(); ... } } } This works for me in VS2015:
file "test.ts":
namespace test { export class AA { prop: string; } } export = test; file "consumer.ts":
import { AA } from "test"; namespace test { export class BB { constructor(a: AA) { a.prop = "some val"; } } }
