A fast and compact HAMT-based KV-Cache with optimistic entries
pessimism
is a fast and compact KV-Cache primarily built for @urql/exchange-graphcache
.
It's a functional and immutable HAMT structure, which increases structural sharing, while
keeping memory usage compact. It supports optimistic entries, which can be invalidated in a single go.
This library works with both TypeScript and BuckleScript (Reason/OCaml).
yarn add pessimism
# or
npm install --save pessimism
The basic methods support making a map and setting, getting, and removing entries:
import * as Map from 'pessimism';
let map = Map.set(Map.make(), "key", "value");
Map.get(map, "key"); // "value"
map = Map.remove(map, "key");
Map.get(map, "key"); // undefined
Optimistic entries can be set using setOptimistic
and cleared using clearOptimistic
:
import * as Map from 'pessimism';
let map = Map.set(Map.make(), "key", "value");
// Set an optimistic entry with the ID 1
map = Map.setOptimistic("key", "temp", 1);
Map.get(map, "key"); // "temp" which is the optimistic value
// Clear all optimistic entries with ID 1
map = Map.clearOptimistic(map, 1);
Map.get(map, "key"); // "value" which was the original value
