Sure ~ assign

Does the same thing as Object.assign but ensure you to only assign existing properties/fields

Getting started

1. Install the package into your node project.

   $ npm i sure-assign

2. Instenciate : You will use it as an object

   const assigner = new ConsistentAssigner ();

3. Use it :

   const obj_A = { ... }; // A is the base
   const obj_a = { ... }; // a is subset of A => OK
   const obj_Ɑ = { ... }; // alfa is superset of A => see complience (*)
   
   const result = assigner.assign(obj_A, obj_a, obj_Ɑ);
   console.log(result);
   
   // Outputed object
   // result : composition of content of theses 3 objects having this relation:
   // Ɑ <= a <= A

Options

The options help you to generate the result object of your desire and more.

Note : None of these is mandatory. It is just a way to tweak the outcomes and behaviors of the assigner

option	type	default	note
verbose	boolean	true
complient	boolean	true
passmiss	boolean	false
secure	boolean	true
sort	string	"no"	no, asc or dsc

1. Complient On false, the assigner will THROW exception to prevent you to make a bad assignement.
2. Verbose Once false, it prevents you to have warnings, when complient is true.
3. Passmiss Tells if you take the triggering objects of the assignment in count in the final result.
4. Secure If you set to false, the assigner do the same as the Object.assign funciton.
5. Sort Offers you the chance to sort the fields or properties of the result object in order ASC, DSC , or NOne of these
