🚀 Usage

Once you've installed the package and set up your configuration, import ReclaimHttps from '@reclaimprotocol/reclaim-https' and use it in your app like this:

import React from 'react';
import {SafeAreaView, StyleSheet, useColorScheme} from 'react-native';
import {Colors} from 'react-native/Libraries/NewAppScreen';
import {ReclaimHttps} from '@reclaimprotocol/reclaim-react-native';

function App(): JSX.Element {
  const isDarkMode = useColorScheme() === 'dark';

  const backgroundStyle = StyleSheet.create({
    container: {
      backgroundColor: isDarkMode ? Colors.darker : Colors.lighter,
      flex: 1,
      justifyContent: 'center',
      alignItems: 'center',
    },
  });

  return (
    <SafeAreaView style={backgroundStyle.container}>
      <ReclaimHttps
        requestedProofs={[
          {
            url: 'https://bookface.ycombinator.com/home',
            loginUrl: 'https://bookface.ycombinator.com/home',
            loginCookies: ['_sso.key'], 
            responseSelections: [
              {
                responseMatch:
                  '\\{"id":{{YC_USER_ID}},.*?waas_admin.*?:{.*?}.*?:\\{.*?}.*?(?:full_name|first_name).*?}',
              },
            ],
          },
        ]}
        // context="Proving on 2023 for eth India" 
        title="YC Login"
        subTitle="Prove you have a YC Login"
        cta="Prove"
        onSuccess={proofs => {
          /*do something*/
          console.log('proofs', proofs);
        }}
        onFail={e => {
          /*do something*/
          console.log('Error', e);
        }}
        buttonStyle={{backgroundColor: 'black'}}
        buttonTextStyle={{color: 'blue'}}
        onStatusChange={(text: string) => {
          console.log("from on Status change, the status is: ", text);
        }}
      />
    </SafeAreaView>
  );
}

export default App;

Here's a description of each property ReclaimHttps accepts:

• url: The URL from where the information is to be extracted. This is typically the webpage where the user's data is located.
• loginUrl: The URL where the user can log in to access the information. If authentication is required to access the data, the user will be redirected to this URL for login.
• loginCookies: An array of cookie names required for authentication. If the webpage uses cookies for authentication, you can specify the names of those cookies here. These cookies will be passed along with the request to the url.
• responseMatch: A regular expression to extract specific information from the webpage. If you only need to extract a specific piece of information from the webpage, you can specify a regex pattern here. The SDK will search for this pattern in the HTML of the webpage and extract the matching content.
• context: Context message for the proof request (Optional)
• title: The name of your application.
• subTitle: The sub title of the component button, usually a short description about the claim.
• cta: The title of cta button.
• onSuccess: A Function that returns proofs after success.
• onFail: A Function that returns Error when the proof generation fails.
• showShell: A boolean to show the shell of the component, default is true (Optional)
• verifyingCta: A message to show to the user while verification is in progress (Optional)
