Angular TS To JS Migration

Angular TS → JS Migration Rules

When migrating .ts (Angular) components to .js:

1. Remove all Angular imports, decorators (@Component, @Input), and TypeScript types
2. Remove interfaces and type annotations
3. Remove all Angular lifecycle interfaces
4. For simple fields components extend FieldBaseComponent if possible and reasonable.
5. For Container components extend ContainerBaseComponent if possible and reasonable.
6. For rest of components extend BaseComponent
7. ngOnInit → init() with componentsManager.onComponentAdded(this)
8. ngOnDestroy → destroy() with super.destroy() and componentsManager.onComponentRemoved(this)
9. Merge onStateChange into checkAndUpdate()
10. updateSelf → #updateSelf() (private); add #sendPropsUpdate() at end
11. Add update(pConn, ...) method for external re-rendering
12. Replace this.pConn$ → this.pConn; remove all as any casts
13. Normalize quotes to double quotes
14. If there is some external dependency try to look in additional provided ts files and copy its content to migrated js. If nothing is found try to find existing equivalent in js files or create mocked implementation.
15. When migrating parts of code prefer copy-paste over code modification.
16. Never change logic of migrated components.
17. In sdk-pega-component-map.js uncomment migrated component entry in pegaSdkComponentMap and also import line. Fix imported component path.
