( LocalStorageRepo )

A repo generator that uses only on key of the sessionStorage to store all data in a unique Array. is write in pure ES5 and implements a comple generic CRUD.

Goals

To have a generic repo (CRUD) generator linked to one key of the LocalStorage for use it as a lightweitgt persistence system directly in the browser.

you can use for ...

some examples Store all data you need indexed and easly accesible as you can do with a "repo" as in a imaginary animal clinic.

petsRepo = new LocalStorageRepo("pets" , "name");
productRepo = new LocalStorageRepo("products", "idProduct");
 
petsRepo.create({name:"kytybity", specie: "cat", clinicalData:"have a large tail"});
petsRepo.create({name:"rufo", specie: "dog", clinicalData:"Wooof"});
console.log ( petsRepo.findOneById("kytybity") )
petsRepo.update({name:"kytybity", specie: "cat", clinicalData:"have no tail, we cut it"});
petsRepo.findBy("specie" , "cat");//find all cats only , no dogs.

but you can do some other stuff , like ... store functions as text indexed by name and rerun later ;) dont know why someone want to do this :P

functions = new LocalStorageRepo("functions", "name")
functions.update({name:"somefunc", text: sumefunc.toString()})
eval((functions.findOneById("somefunc").text)
 
or if you want avoid "eval" you can do like this too ( is a bit more  hkr ... XD)
var getFooFromStorageLoL = new Function( "return " + (new LocalStorageRepo("functions", "name")).findOneById("foo").text )
var foo = getFooFromStorageLoL();
//now you can use your foo as allways... 
 

save an Oajax response.... and all that you wants , if it can be stored in a nutshell of course ^^

rxjs.ajax("/my/great/stuff").subscribe(repo.create)
