There's no declaration for define function

Maybe try setting your tsconfig.json to use commonjs, as it looks like it's using AMD by default for some reason.

{
  "compilerOptions": {
    "module": "commonjs"
  }
}

[devongovett]

We default the module option to commonjs here but you can override it in your tsconfig.json. Any chance that's happening? I suppose we could enforce it to commonjs in parcel.

[itsMapleLeaf]

Yeah, that's why I thought it was weird. After some investigation, the simple example code provided doesn't output any AMD wrapping at all unless require, export, etc. are used. @alexeypetrushin What's your typescript version? And is this the _only_ file in the entire project? No tsconfig or anything?

[al6x]

Hmm, I already killed the example, sorry don't have it anymore. I believe there were no tsconfig, just basic example without any config.

I have the same problem. I have tsconfig file. It works perfectly with the module:umd option but unfortunately does not work with amd. But I still need to compile with amd for my project and now I see only one solution to does not specify the module option in tsconfig file and add it directly during compilation: tsc --module amd. I use jasmine-ts for testing and it adds automatically module type commonjs if it is not specified in tsconfig. Maybe it will be useful for someone :)
