keya

Keya

A simple, universal document store. Keya supports the following storage mediums:

• SQLite (Nodejs)
• IndexedDB (Browser)
• LocalStorage (Browser, backup)

API

In general keya stores can be thought of as a Map that acts asynchronously.

Import

import * as keya from "keya";
// Or, if not using modules:
const keya = require("keya");

Access a store

If the store does not exist when you call this, it will be created automatically for you

const store = await keya.store("records");

Note: Store names need to follow SQLite Table name rules/should generally only be alphanumeric characters without spaces. Beyond that can lead to unexpected issues and undocumented behavior

Hydration

keya supports an optional Hydration Function to be passed to .store when initalizing. This defaults to JSON.parse. The hydration function will be passed the stored string and should return the appropriate value. An example is shown below that allows keya to store Maps long-term.

// Add a custom hydration function
const store = await keya.store("calls");

// Custom conversion functions stores a map by it's entry list
store.stringify = map => JSON.stringify([...map.entries()]);
store.hydrate = string => new Map(JSON.parse(string));

// Construct the Map to be stored
const map = new Map([
  [32, "a"],
  [45, "b"]
])

store.set("map", map);

// In another session

const map = store.get("map");

Set a value

await store.set("document", { value: 345 });

Get a value

const record = await store.get("document");

Find values

const records = store.find(
  (value, name) => name.includes("e") && value.v == 12
);

Clear the store

store.clear();

Get all values

store.all(); // [ {key: "hello", value: 43 }, { key: "world", value: 12 } ]
