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

@kako351/react-native-gemini-nano

Android 向けの React Native TurboModule ライブラリです。ML Kit Prompt API を通して、端末上の Gemini Nano を利用します。

Requirements

  • React Native 0.84 以上
  • Android New Architecture 有効
  • Android API 31 以上
  • Gemini Nano Prompt API 対応端末

Install

npm install @kako351/react-native-gemini-nano

Android 側は autolinking を前提にしています。

Usage

import GeminiNano, {useGeminiNano} from '@kako351/react-native-gemini-nano';

const availability = await GeminiNano.getAvailability();

if (availability.status === 'needs_download') {
  await GeminiNano.downloadModel();
}

const text = await GeminiNano.generateText('3行で要約してください');

Hook を使う場合:

const {
  availability,
  refreshAvailability,
  downloadModel,
  generateText,
  generateTextStream,
  streamedText,
  isStreaming,
  downloadState,
} = useGeminiNano();

API

  • isAvailable(): Promise<boolean>
  • getAvailability(): Promise<{ status; isAvailable; message; errorCode? }>
  • downloadModel(): Promise<void>
  • generateText(prompt: string): Promise<string>
  • generateTextStream(prompt: string): void

getAvailability().status は次を返します。

  • available
  • needs_download
  • downloading
  • needs_system_update
  • busy
  • unavailable
  • unknown

Notes

  • 実行基盤は ML Kit Prompt API ですが、実際のオンデバイス推論は AICore / Gemini Nano により行われます。
  • 端末が対応機種でも、モデル未配信やダウンロード未完了の間は available にならないことがあります。
  • サンプルアプリは example/ に入っています。
