Pooler

A generic pooling interface and TypeScript/JavaScript implementation.

The interface

The heart of pooler is the interface. The interface is largely taken from the Go standard library where the two key methods are get and put.

Unique to this library is the method use. The use method is a convenience feature that abstracts the logic of both get and put by passing in a callback to be executed with a value from the pool. This is especially nice for making single queries to a database. It removes the need for a lot of boilerplate code, and also removes the possibility you forget to put the value back in the pool.

Note that the factory function implements an equal jitter exponential backoff for retrying resource creation.

Basic Usage

To get started, created a pooler from the implementation's option object.
