Methods

createInstance

▸ Static createInstance<T, R>(...args): T

Creates the single instance of the child class if one was not already created.

Multiple calls will return the same instance. Essentially throwing away the arguments to the subsequent calls.

Note: this is a racy function, if two (or more) calls are racing to call this function only the first's arguments will be used.

Type parameters

Name	Type
T	T
R	R: any[]

Parameters

Name	Type	Description
...args	R	The constructor arguments for the child class

Returns

T

An instance of the child class

---

getInstance

▸ Static getInstance<T, R>(strict): T

Get the instance of the child class that was previously created.

Type parameters

Name	Type
T	T
R	R: any[]

Parameters

Name	Type	Description
strict	boolean	If false will return undefined instead of throwing when an instance doesn't exist. Default: true

Returns

T

An instance of the child class

---

resetInstance

▸ Static resetInstance(): void

Delete the instance of the child class.

Note: this doesn't prevent callers of getInstance from storing the result in a global.

There is no way in JS or TS to prevent globals like that.

Returns

void
