angularjs-di-patterns

Read-only mining codemod that scans AngularJS JavaScript source for dependency-injection
annotation styles and emits a di_pattern metric for migration assessment, including
minification-safety classification. It never modifies files — every match is reported via
codemod:metrics and the transform always returns null.

What it detects

`di_style`	Example	Minification safe
`array`	`['$http', function ($http) {}]`	yes
`inject_property`	`Foo.$inject = ['$http'];`	yes
`inline`	`.service('Foo', function ($http) {})` — anonymous function passed directly to a registration call	no
`implicit`	`function Foo($http) {}` referenced by name in a registration call, with no `$inject` annotation anywhere	no

inline and implicit both rely on parameter names for injection, so they break once a
minifier renames those parameters — flagged as the primary automation targets before a
production build pipeline is minified.

Metric cardinality

Each finding increments di_pattern with:

ts
{
  file: "app/invoices/invoice.service.js",
  line: "9",
  snippet: "function ($http) { ... }",
  di_style: "array" | "inject_property" | "inline" | "implicit",
  minification_safe: "true" | "false",
  migration_category: "di",
  risk: "low" | "medium" | "high",
  automation: "full" | "partial",
  effort_points: "1" | "2" | "3",
  recommended_phase: "phase-1",
}
