TypeScript compilation causing dependency errors

Question

I am compiling multiple TypeScript files into a single JavaScript file. Say for example they are called:

A.ts // depends on C.ts
B.ts // depends on C.ts
C.ts

When I checked the JavaScript output, I found a problem: TypeScript's __extends function failed due to being passed an undefined value.

Compilation should have been in the following order:

C.ts // because A and B depend on this respectively.
A.ts
B.ts

but unfortunately they were compiled according to their names (alphabetically) rather than in dependency order.

• Can this be solved?
• Is the TypeScript team aware of this issue?

Note: This is a Visual Studio TypeScript compiler issue. Presumably using the command line compiler would fix this, but I would like to compile from Visual Studio.

TypeScript doesn't do automatic file ordering. You should compile with some --module flag set e.g. commonjs and then let an external module loader resolve these dependency chains for you.
