Disassination pocket native apps made of browser dapps: a guide
While blockchain technology is developing, decentralized applications (DAPPS) are becoming increasingly popular. However, one of the main problems with which users stand with is to connect your preferred item pockets to a certain DAPP without having to manually download and install them. This is where the detour of items of native apps made of browser -dapps comes into play.
In this article, we will examine how to create a function, press the “Buy” button on a browser -dapp and convert to an envelope app like Metamask for signing and spending tokens.
Why redirect wallet apps?
Remeding of items of browser Dapps native apps offers several advantages:
* Comfort : Users can access their preferred wallet app without manually downloading and installing them.
* Safety : Implies are usually designed taking into account security and offer robust protection for user money.
* barrier -free : This function makes it easier to use users who do not use native wallets or have a limited technical know -how.
Requirements
Before we deal with the implementation, make sure you have the following requirements:
- A browser dapp that uses an item pockets app (e.g. Metamask)
- A handbag -Setup with a compatible Ethereum node
- A wall pocket provider such as a metamask or trust pocket
The implementation
In order to redirect native wallets native apps from browser dapps, you have to create some components:
- Wallet provider : This is the core component that is responsible for interaction with the user’s wallet. In this case we use the Metamask library in JavaScript.
- Derirance function : This function is called up when the purchase button is pressed and the user redirects to his preferred item pockets.
- WebApp setup : We have to set up a web application with which the detour functionality can be processed.
Step-by-step implementation
Here is a sample implementation of how you can create this function:
`JavaScript
// import necessary libraries
Const Web3 = demands (‘Web3’);
Const metamask provider = required (‘metamask provider’);
Const webapp = demands (‘./ WebApp’); // assuming your web application setup
// Set up the articulated pocket provider with the user’s metamask account
Leave wall set providers;
if (process.env.walletprovider === ‘metamask’) {
wallet provider = new metamask provider (process.env.metamask_url);
} differently {
console.error (‘non -supported item pocket providers. Please use metamask’);
}
// Define the diversion function
Function Recirectwallet () {
// Get the user’s address from the item pocket provider
Const Useraddress = Walletprovider.Getaddress ();
// redirect the web app
webapp.Redirect (useraddress) return;
}
// Event listener for buying button click click on event.
document.addeventlistener (‘click’, (event) => {
if (event.arget.classlist.contains (‘buy button’) {
recirectwallet ();
}
});
`
Web application setup
To set up a web application that can process this function, you need to create a new project with a framework such as React or Angular. Here is a sample implementation of a basic web application:
`JavaScript
// import necessary libraries
Really import, {usestate} from ‘react’;
Import webapp from ‘./Webapp’;
Const app = () => {
// specify variables to save the address and the user’s item pocket provider
Const [useraddress, setuseraddress] = usustate (”);
Const [Wall provider, setwallet provider] = usustate (zero);
// redirect the function for redirecting the user into its preferred item pockets app
Const Reutirectwallet = Async () => {
if (ballet provider) {
expect Window.open (walletprovider.getwebsiteurl (), ‘_blank’);
} differently {
Console.error (‘not supported, container pockets.
