@batterii/generator-ts-module

A yeoman generator for creating static function modules in Batterii TypeScript projects.

Usage

  yo @batterii/ts-module [options]

Options:
  -h,   --help           # Print the generator's options and usage
        --skip-cache     # Do not remember prompt answers                   Default: false
        --skip-install   # Do not automatically install dependencies        Default: false
        --force-install  # Fail on install dependencies error               Default: false
  -f,   --function       # Name of the first module function
  -m,   --module         # Name of the module, without the extension
  -s,   --stand-alone    # Set if the module will export only one function

Function and Module Names

This generator will create a new .ts file in the src/lib directory with --module as its name, which exports a function with --function as its name. It also will create associated unit test file in the same directory with a .spec.ts extension. If either of these options is omitted, the generator will prompt the user for them.

The function name must be a valid TypeScript identifier in lower camel case, while the module name must be dash-separated lower case. The prompt for the module name defaults to the decamelized function name, so often times you can just press enter here unless you need the module to be named differently.

Stand-Alone Function Modules

Normally, when you create a new module, a describe block for the first function is nested inside a describe block for the while module in its unit test file. This makes it easy to add tests for any related functions that might be added to the same module.

Many modules will export only one function, however, so these nested describe blocks can often become redundant. If you know this will be the case, you can run the generator with the --stand-alone option, which will omit the surrounding describe block, among other elements you're not going to need for a single-function module.

The --stand-alone option is ignored if the module name is not equal to the decamelized function name. This is to enforce naming conventions that make the developer's life easier. A stand-alone function inside a module with a completely different name would be difficult to find based on the test names alone, so this generator does not allow it.

If the --stand-alone option (or its negation --no-stand-alone) is not provided, and the module name is equal to the decamelized function name, the generator will prompt the user to determine what to do.
