state-tokens

Classes and type definitions for state transition tokens for libraries that manage tokens as objects in sets and tables.

install

npm install -save state-tokens

usage

const { 
    TransitionObject, 
    LoginTransitionObject, 
    LogoutTransitionObject, 
    RegistrationTransitionObject, 
    ProcessTransitionObject
} = require("state-tokens")

...

function using_tokens() {

	let lt_object = new LoginTransitionObject('user')  // for user processing
	let pt_object = new ProcessTransitionObject('media') // for media operations
	
	// set the token of the transition object (not a constructor parameter)
	// The token will be useless to most apps if the token is not set.
	let session_token = app_token_maker()
	lt_object.set_token(session_token)
	let process_token= app_token_maker()
	pt_object.set_token(process_token)

	let tok = pt_object.token // fields are public...
}

These objects may be stored and fetched by their token key.

The base type, TransitionObject, has fields for identifying its location in a process chain. In particular, the secondary_action field can be used to check if the token should do some second action. Within copious-transitions for example, a browser could check to see if more operations should be performed by a server until an operation is completed; that is, the operation may take a few steps and use server side and client side views of the token to decide how to proceed through a process.

The token object also has fields elements, object, initially empty, and also amelioritive_action which if set, may be used to direct the server as to how to handle process error events in relation to other processes or a browser client.
