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

@infinitered/react-native-mlkit-core

Description

This is a shared library for RNMLKit that contains helper functions and shared code for various packages. It offers some helpful methods that are used by many apps on the React Native (JS) side and includes functionality to work with images and bounding boxes.

Installation

Use the following command to install the package:

npm install @infinitered/react-native-mlkit-core

Usage

RNMLKitImage

Swift

Use this class in Swift to create and manage images with MLKitVision. It provides utility methods for loading images and managing their vision representations.

import RNMLKitCore
let image = RNMLKitImage(imagePath: imagePath)
// ...
  • imagePath - should be the localUri of the image to process. i.e. Asset.localUri from an Expo Asset or Image.uri from an ImagePickerAsset.

Kotlin

Use this class in Kotlin to create and manage images with MLKitVision. It provides utility methods for loading images and managing their vision representations.

import com.infinitered.reactnativemlkitcore.RNMLKitImage

val imageUri = Uri.parse(imagePath)
var image:InputImage = RNMLKitImage(imagePath, appContext.reactContext!!).image
// ...
  • imagePath is the localUri of the image to process. Asset.localUri from an Expo Asset or Image.uri from an Expo ImagePickerAsset.
  • appContext is the AppContext from your expo module -- it's accessible as a property on the Module class.

React Components

BoundingBoxView

Renders a bounding box based on the specified dimensions and scale.

import { BoundingBoxView } from "@infinitered/react-native-mlkit-core";
// ...
<BoundingBoxView box={box} scale={scale} />;
  • box is the bounding box to render of type BoundingBox
/**
 * Represents a bounding box with origin, size, color, label, and width properties.
 */
export interface BoundingBox {
  origin: { x: number; y: number };
  size: { x: number; y: number };
  color?: string;
  label?: string;
  width?: number;
}

ImageWithBoundingBoxes

Renders an image with bounding boxes drawn over specified regions.

import { ImageWithBoundingBoxes } from "@infinitered/react-native-mlkit-core";
// ...
<ImageWithBoundingBoxes image={image} boundingBoxes={boundingBoxes} />;
  • boundingBoxes is an array of BoundingBox objects to render over the image.
  • image is the image to render. Accepts an Image from expo-image

Hooks

Several hooks are included to assist with layout and scaling:

  • useBoundingBoxStyle: Calculates the style object for a bounding box.
  • useImageScale: Calculates the image scale based on the provided parameters.
  • useLayout: Handles layout change events.
