Angular2/TypeScript Coding Guidelines

I am curious about the common practices and consensus among the Angular2 community when it comes to writing reusable code in TypeScript. I have gathered some information and questions related to Angular2 that I would like to discuss.

Organizing Module/App Structure and File Naming

  • In the official tutorial, all code is placed in the app directory, while dependencies like node_modules or typings are kept in the parent directory.

  • Using lowercase file names, .component.ts extension for components, and .service.ts for services. Is putting all files in the same directory going to create a messy structure?

  • Following the guideline of having one class/interface/enum per file. Should naming conventions be based on the Microsoft TypeScript Coding guidelines for consistency?

Bundle Modules

  • Is it recommended for modules to compile and bundle themselves using the postinstall npm hook? Or is it better to directly provide a bundled version on git similar to JavaScript libraries?
  • When expecting a module to be used only by the browser, is it preferable to utilize the system type of modules by default, or should one always opt for UMD?
  • Are there specific advantages to using CommonJS or AMD over system?

Integration of 3rd Party Modules

  • Should one assume that other developers will embed the modules with <script> tags or load them using System.import()?
  • If the modules have dependencies on other JavaScript libraries, is it more efficient to provide a bundled version with all dependencies included or just define them in the package.json file?
