Spinning Reservoir is a TypeScript class that implements a circular buffer with a fixed maximum size. When the buffer is full and a new item is added, the oldest item in the buffer is discarded.
Install the package with npm:
npm install spinning-reservoirCreates a new SpinningReservoir with the specified maximum size.
new SpinningReservoir(20)Adds a new item to the buffer. If the buffer is full, the oldest item is discarded.
const buffer = new SpinningReservoir()
console.log(buffer.size) // 0
buffer.push('hi')
buffer.push('there')
console.log(buffer.size) // 2Clears all items from the buffer.
const buffer = new SpinningReservoir()
buffer.push('hi')
console.log(buffer.size) // 1
buffer.clear()
console.log(buffer.size) // 0Returns the item at the specified index, or undefined if the index is out of bounds.
const buffer = new SpinningReservoir()
buffer.push('hi')
buffer.push('there')
console.log(buffer.get(0)) // 'hi'
console.log(buffer.get(1)) // 'there'The current number of items in the buffer.
const buffer = new SpinningReservoir()
console.log(buffer.size) // 0
buffer.push('hi')
buffer.push('there')
console.log(buffer.size) // 2The maximum size of the buffer. Can be changed after the buffer is created, but must be an integer greater than 0.
const buffer = new SpinningReservoir()
console.log(buffer.maxSizeValue) // 10
buffer.maxSizeValue = 20
console.log(buffer.maxSizeValue) // 20Returns an iterator that iterates over the items in the buffer in the order they were added.
const buffer = new SpinningReservoir<string>()
buffer.push('hi')
buffer.push('there')
for (const value of buffer) {
console.log(value)
}
const it = buffer[Symbol.iterator]()
let r = it.next()
while (!r.done) {
console.log(r.value)
r = it.next()
