filestore-json

Checks

• 
• 
• 

Easily sync JSON objects of any shape with the filesystem.

Features

• Read & write to JSON files on a storage device without the need to interact with the filesystem.
• Persistant data between process restarts.
• Ability to determine age (ms since last write).
• Cache JSON responses from network requests.
• Automaticly updates internal value when JSON file is modified.
• Strong type internal value with type annotations.

Examples

Creating a store

import JSONStore from "filestore-json";
import path from "path";

// Initialize the store.
const store = JSONStore.from(path.resolve("path/to/your/store.json"));

// With types
type Type = Record<string, any>;
const store = JSONStore.from<Type>(path.resolve("path/to/your/store.json"));

Reading & writing to the store

// Read value of store.
console.log(store.value); // -> {}

// Update store value.
store.value = { myObject: false };

// Read new value of store.
console.log(store.value); // -> { myObject: false }

Creating a store with default values

// Create object with store defaults
const defaults = { defaultValue: true };

// Initialize store.
const store = JSONStore.from(path.resolve("path/to/your/store.json"), defaults);

// Read value of store.
console.log(store.value); // -> { defaultValue: true }

// Update store value.
store.value = { myObject: false };

// Read new value of store.
console.log(store.value); // -> { myObject: false, defaultValue: true }

Resetting a stores value back to the default

// Update store value.
store.value = { myObject: false };

// Read new value of store.
console.log(store.value); // -> { myObject: false }

// Clear value
store.clear();

// Read value of store.
console.log(store.value); // -> {}

Getting the age of the store (ms since last write)

// Read age of store.
console.log(store.age); // -> 0
