Metamask Import Error in React Native Project
Do you use the official integration of React Native for Metamask, the popular cryptocurrency portfolio? Unfortunately, this can sometimes lead to disappointing mistakes in importing the Metamasksdk module. In this article we will go through what is happening and how to resolve it.
The problem:
When you create a new Native Project React with NPX React-Navity Init, install Metamask SDK using a 'NPM installation of a meta-mask-sdk. However, this installation may not include the necessary Metamask addictions. In particular, the error arises when trying to import the Crypto fromMeta-Mask-SDK module.
Error message:
The error message is quite simple:
`
Error: While Importing Metamask-SDK Resolve Module ‘Crypto’ Error
`
This shows that there is a conflict between SDK Metamask and the dependencies of your project, more specially the “Crypto” module.
Why this happens:
When installing Metamask SDK using NPM Install, it probably included” crypto “. However, when importing Meta-Mask-SDK, React Native is not able to find the necessary “Crypto” module, which leads to this error message.
Solving error:
To resolve this problem, try the following steps:
- Check the dependencies of your project: Make sure you have not removed accidentally or deactivate the necessary Metamask addictions.
- Update
Package.json:
Check that the” Crypto “module is included in the” dependencies “of your project. If not, add it using the following syntax:
`json
“Addictions”: {
“Crypto”: “^4.0.0”
}
`
- Use a different method to import Metamasksdk: Instead of importing directly from
Meta-Mask-SDK, try using a more exquisite approach by creating your own copy ‘Metamasksdk’ and configure it to use to useCryptomodule. You can find an example conversion in the official documentation of React Native: [Import Metamask SDK] (
Example code:
Here is a simple fragment of codes that demonstrate how to create your own copy Metamasksdk and to configure it to use the ‘Crypto:
jsx
Import {metamasksdk} from ‘@meta-maask/sdk’;
Const metamask = new metamasksdk ({
Activated: True,
Options: {
Accounts: {
// indicate your account or network of Ethereum here
Accounts: [
‘0x … your_account_address …’
)
},
Chainid: 3, // Ethereum Mainnet
},
Suppliers: [‘Metamask’]
});
`
Following these steps and adjusting your imports accordingly, you should be able to solve the Crypto module error when you use Metamask SDK in your Native Project.
