- ✅ Ticket 1.1: Estructura Clean Architecture en backend
- ✅ Ticket 1.2: Schemas Zod compartidos
- ✅ Ticket 1.3: Refactorización drugs.ts (1362 → 8 archivos modulares)
- ✅ Ticket 1.4: Refactorización procedures.ts (3583 → 6 archivos modulares)
- ✅ Ticket 1.5: Eliminación de duplicidades (~50 líneas)

Cambios principales:
- Creada estructura Clean Architecture en backend/src/
- Schemas Zod compartidos en backend/src/shared/schemas/
- Refactorización modular de drugs y procedures
- Utilidades genéricas en src/utils/ (filter, validation)
- Eliminados scripts obsoletos y documentación antigua
- Corregidos errores: QueryClient, import test-error-handling
- Build verificado y funcionando correctamente

`dlv(obj, keypath)`

Safely get a dot-notated path within a nested object, with ability to return a default if the full key path does not exist or the value is undefined

Why?

Smallest possible implementation: only 130 bytes.

You could write this yourself, but then you'd have to write tests.

Supports ES Modules, CommonJS and globals.

Installation

npm install --save dlv

Usage

delve(object, keypath, [default])

import delve from 'dlv';

let obj = {
	a: {
		b: {
			c: 1,
			d: undefined,
			e: null
		}
	}
};

//use string dot notation for keys
delve(obj, 'a.b.c') === 1;

//or use an array key
delve(obj, ['a', 'b', 'c']) === 1;

delve(obj, 'a.b') === obj.a.b;

//returns undefined if the full key path does not exist and no default is specified
delve(obj, 'a.b.f') === undefined;

//optional third parameter for default if the full key in path is missing
delve(obj, 'a.b.f', 'foo') === 'foo';

//or if the key exists but the value is undefined
delve(obj, 'a.b.d', 'foo') === 'foo';

//Non-truthy defined values are still returned if they exist at the full keypath
delve(obj, 'a.b.e', 'foo') === null;

//undefined obj or key returns undefined, unless a default is supplied
delve(undefined, 'a.b.c') === undefined;
delve(undefined, 'a.b.c', 'foo') === 'foo';
delve(obj, undefined, 'foo') === 'foo';

Setter Counterparts

dset by @lukeed is the spiritual "set" counterpart of dlv and very fast.
bury by @kalmbach does the opposite of dlv and is implemented in a very similar manner.
