Add requirement for main.ts on the server in README.md

[sclausen]

You can't choose another main-module than main.ts on the server, because it is hardcoded in barbatus:angular2.

[barbatus]

Yes, I'll add it for sure. Though, presence of main.ts is not required like you said; if it's there it'll be imported if it's not you'll need to import another module manually.

[sclausen]

How do you import another module on the server to be executed at startup?

[barbatus]

Same way you'd do it for client side:
add main.js with

Meteor.startup(function(){
 System.import('server/foo').await();
})

[sclausen]

Hmm, maybe I got the wrong idea how stuff works, bu if you don't create a main.ts on the server, no code will be executed there, so where would you define this import?

[sclausen]

Maybe I slowly got it. js files are executed normally without being registered as system.js modules, so
I could create a foo.js on the server with

Meteor.startup(function(){
 System.import('server/foo').await();
})

right!?

[barbatus]

@sclausen yes, exactly. foo.ts

[sclausen]

Hmm, but the server doesn't know about system.js…

While processing files with barbatus:angular2 (for target
   os.linux.x86_64):
   /server/notmain.ts:16:2: Cannot find name 'System'.

Do I have to manually add systemjs:systemjs to my project, or am I doing something still wrong?
I think this would be an inconvenient workaround to use something different than the automatically loaded main.ts.

[barbatus]

You seem to be missing something. If there wasn't System defined on the server, it wouldn't work even with main.ts.

[barbatus]

systemjs:systemjs should be added to your app by the package.

[sclausen]

Okay, I don't know, what I did wrong before. Everything now works as expected. The custom import in a server-side js-file works like a charm.

[barbatus]

Use System in pure .js-files, in .ts ones you don't need it

[sclausen]

Yeah I know, I got that after writing my third comment in this issue, but I did something wrong and was confused about the server not knowing anything about the systemjs:systemjs in my js-file although added it in barbatus:angular2… Thanks for clarification! ☺️
