Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@najihmld/expo-fs-storage

An persistent, key-value storage system for React Native Expo, which does not have size limitations of @react-native-async-storage/async-storage

Installation

With npm:

npm install @najihmld/expo-fs-storage

With Yarn:

yarn add @najihmld/expo-fs-storage

With Expo CLI:

npx expo install @najihmld/expo-fs-storage

Usage

ExpoFsStorage can only store string data. In order to store object data, you need to serialize it first. For data that can be serialized to JSON, you can use JSON.stringify() when saving the data and JSON.parse() when loading the data.

Importing

import ExpoFsStorage from "@najihmld/expo-fs-storage";

Storing data

setItem() is used both to add new data item (when no data for given key exists), and to modify existing item (when previous data for given key exists).

Storing string value

const storeData = async (value) => {
  try {
    await ExpoFsStorage.setItem("my-key", value);
  } catch (e) {
    // saving error
  }
};

Storing object value

const storeData = async (value) => {
  try {
    const jsonValue = JSON.stringify(value);
    await ExpoFsStorage.setItem("my-key", jsonValue);
  } catch (e) {
    // saving error
  }
};

Reading data

getItem returns a promise that either resolves to stored value when data is found for given key, or returns null otherwise.

Reading string value

const getData = async () => {
  try {
    const value = await ExpoFsStorage.getItem("my-key");
    if (value !== null) {
      // value previously stored
    }
  } catch (e) {
    // error reading value
  }
};

Reading object value

const getData = async () => {
  try {
    const jsonValue = await ExpoFsStorage.getItem("my-key");
    return jsonValue != null ? JSON.parse(jsonValue) : null;
  } catch (e) {
    // error reading value
  }
};

Remove data

Removes item for a key, invokes (optional) callback once completed.

const removeData = async () => {
  try {
    await ExpoFsStorage.removeItem("my-key");
  } catch (e) {
    // remove error
  }

  console.log("Done.");
};

Using zustand for persist your store's data

import ExpoFsStorage from "@najihmld/expo-fs-storage";
import { create } from "zustand";
import { persist, createJSONStorage } from "zustand/middleware";

const useFishStore = create(
  persist(
    (set, get) => ({
      fishes: 0,
      addAFish: () => set({ fishes: get().fishes + 1 }),
    }),
    {
      name: "expo-storage", // name of the item in the storage (must be unique)
      storage: createJSONStorage(() => ExpoFsStorage),
    }
  )
);

export default useFishStore;
