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 🙏

Screen Capture Secure View

React Native에서 사용하기 위한 iOS 캡처 방지

설치

npm install @testbank-inc/screen-capture-secure-view

yarn add @testbank-inc/screen-capture-secure-view

useScreenCaptureSecure로부터 네 개의 메서드를 불러올 수 있으며 다음과 같이 사용할 수 있습니다.

  1. addScreenCaptureListener : callback을 넘겨주어 스크린샷이 일어났을 때 행동 작성
  2. isSecure : promise 형태로 현재 secure 값이 true인지 false인지 return
  3. enableSecure : 현재 view를 캡처 불가능 view로 설정
  4. disableSecure : 현재 view를 캡처 가능 view로 설정

아래와 같이 ScreenCaptureSecureView컴포넌트를 생성하여 보안이 필요한 다른 컴포넌트를 감싸서 캡처 방지 및 녹화 방지를 할 수 있습니다.

예시

// ScreenCaptureSecureView.tsx
import React from 'react';
import { Alert, StyleSheet, View, ViewProps } from 'react-native';
import { useFocusEffect } from '@react-navigation/native';
import { useScreenCaptureSecure } from '@testbank-inc/screen-capture-secure-view';

type TScreenCaptureSecureViewProps = {
  children?: React.ReactNode;
} & ViewProps;

export function ScreenCaptureSecureView({ ...props }: TScreenCaptureSecureViewProps) {
  const { addScreenCaptureListener, isSecure, enableSecureView, disableSecureView } = useScreenCaptureSecure();

  useFocusEffect(
    React.useCallback(() => {
      const subscription = addScreenCaptureListener(() => {
        // ... what you gonna do after screen captured
      });

      return () => {
        handleOutFocused();
        subscription?.remove();
      };
    }, []),
  );

  const handleOnLayout = async () => {
    const secureVal = await isSecure();
    if (!secureVal) {
      enableSecureView();
    }
  };

  const handleOutFocused = async () => {
    const secureVal = await isSecure();
    if (secureVal) {
      disableSecureView();
    }
  };

  return (
    <View onLayout={handleOnLayout} style={styles.secureView}>
      {props.children}
    </View>
  );
}

const styles = StyleSheet.create({
  secureView: {
    position: 'absolute',
    left: 0,
    top: 0,
    width: '100%',
    height: '100%',
  },
});
// [OtherComponent].tsx
import React from 'react';
import ScreenCaptureSecureView from "./ScreenCaptureSecureView";

export function OtherComponent() {
  return (
    <ScreenCaptureSecureView>
      {/*  Secured View  */}
    </ScreenCaptureSecureView>
  );
}
