Optimization of Metamask’s behavior: how to prevent Metamask from starting the DAPP load
As a blockchain beginner, you probably know the transparent integration of Metamask in your React application. However, have you already noticed that when you deploy your decentralized application (DAPP), the Metamask wallet begins automatically and synchronizes with the blockchain? This behavior can be frustrating if you don’t want Metamask to interfere with your user experience.
In this article, we will explore why Metamask begins on the DAPP load and provide some tips to optimize his behavior.
Why does Metamask start on DAPP LOAD?
When you deploy a new DAPP, Metamask is automatically configured to connect to the blockchain. This configuration is stored in the extension of the browser Metamask or in the Metamask.jsfile (if you have it). The Meta mask is responsible for initializing the portfolio and establishing a connection with the Ethereum network.
Why does Metamask start on DAPP LOAD?
The reason why Metamask starts automatically when your DAPP load is due to its behavior in Weba Visman mode (wasm). When you deploy a wasm module, like the JavaScript contract in your React application, Metamask will try to initialize and connect to the blockchain.
To prevent Metamask from starting the DAPP load, you will have to deactivate this automatic initialization for the WASM module. Here's how:
Solution 1: Disable automatic initialization usingmetamask.js
You can change theMétamask.jsfile (if you have it) to deactivate Metamask's automatic initialization:
Javascript
Const Metamask = Window.metamask;
If (! Metamask) {
// Add your code here
}
'
This will prevent Metamask from starting automatically on the DAPP load.
Solution 2: Disable automatic initialization using webpack configuration
Alternatively, you can configure theMétamask.js’ file to deactivate automatic initialization when deploying a WASM module using webpack:
`Javascript
Export module = {
// ...
Module: {
rules: [
{
Test: /\.(js|jsx)on/,
Exclude: / node_modles /,
Use: "React-hot-loader / webpack",
Options: {
Preload: False,
Postload: True,
},
},
],
},
};
'
This configuration will deactivate Metamask's automatic initialization for wasm modules.
Solution 3: Configuremetamask.js’ using a personalized script
Another approach is to configure the Métamask.js' file using a personalized script, which can be executed before deploying your DAPP:
Javascript
// metamask.js (example)
Const Metamask = Window.metamask;
If (! Metamask) {
const config = require ('./ config');
if (config.startonload) {
// Define the configuration here
Metamask.start ();
}
}
` ‘
This script can be executed before deploying your DAPP, and it will deactivate Metamask’s automatic initialization for the module.
Conclusion
By understanding why Metamask begins on the DAPP load and by implementing one of these solutions, you can optimize his behavior and prevent him from interfere with your user experience. Do not forget to experiment with different configurations to find the best approach for your specific use case. Good deployment!
