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

React Native Gryfo

Biblioteca adaptada do Android nativo para o React Native com o sistema de reconhecimento Gryfo.

Exemplo

import Gryfo from "react-native-gryfo";

// Para iniciar a activity de cadastro
Gryfo.startRecognizeActivity()
  .then(res => {
    console.log(res);
  })
  .catch(err => {
    console.log(err);
  });

// Para iniciar a activity de registro
Gryfo.startRegisterActivity()
  .then(res => {
    console.log(res);
  })
  .catch(err => {
    console.log(err);
  });

Instalação

Para instalar a biblioteca

yarn add react-native-gryfo

No androidManifest é necessário colocar um atributo para que ele faça o replace do nome e do tema

./android/app/src/main/AndroidManifest.xml

<manifest ...
  xmlns:tools="http://schemas.android.com/tools"
  ...
  >
    <application tools:replace="android:name, android:theme"
      ...
    </application>

</manifest>

Após isso, é necessário adicionar os seguintes blocos nos dois build.gradles do react dentro da pasta ./android e ./android/app

./android/build-gradle

buildscript {

  ext {
    minSdkVersion = 21 // Trocar para versão 21
  }

  // Adicionar o mavenCentral como repositorio
  repositores {
    mavenCentral()
  }

  // Adicionas as seguintes depencencias
  dependencies {
    classpath 'io.realm:realm-gradle-plugin:6.0.0'
    classpath 'com.google.gms:google-services:4.3.3'
  }
}

// Adicionar os seguintes repositórios no "allprojects"
allprojects {
  repositories {
    maven {
      url 'http://gpm.gryfo.com.br:8081/artifactory/gradle-dev'
      credentials {
        username = "username"
        password = "password"
      }
    }
    mavenCentral()
    maven {
        url 'https://s3.amazonaws.com/fabric-artifacts-private/internal-snapshots'
    }
  }
}

//Adicionar o seguinte bloco no final do arquivo
task clean(type: Delete) {
  delete rootProject.buildDir
}

./android/app/build-gradle

android {
  // Adicionar os seguintes blocos na tag android
  packagingOptions {
      pickFirst "META-INF/kotlinx-io.kotlin_module"
      pickFirst "META-INF/atomicfu.kotlin_module"
      pickFirst "META-INF/kotlinx-coroutines-io.kotlin_module"
  }
  aaptOptions {
      noCompress "tflite"
  }
  sourceSets {
      main {
          jniLibs.srcDirs = ["libs"]
      }
  }
}

// Implementar 2 dependencias
dependencies {
  implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
  implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0-alpha02'
}

Métodos

A biblioteca oferece 2 métodos e ambos são uma promisse do Javascript. Um é utilizado para registrar o usuário e um para reconhecer.

startRegisterActivity()

Abre a câmera do device com um botão para tirar uma foto depois de 3 segundos. Após o usuário confirmar a foto, a biblioteca retorna uma ID.

startRecognizeActivity()

Abre a câmera do device e procura pelo rosto do usuário. Após reconhecer, a biblioteca retorna a ID da pessoa cadastrada.
