Using the Storage Module in Wallet API Core Client
The Storage Module provides a way to interact with Ledger Live's internal storage. You can store and retrieve data using key-value pairs.
Storage Module Overview
Access the Storage module via walletApiClient.storage
.
Methods:
1. Get Data
Retrieve data from Ledger Live's internal storage by specifying a key. You can also specify a store ID to retrieve data from a particular store.
walletApiClient.storage.get(key: string, storeId?: string): Promise<string | undefined>
Parameters:
key
(required): A string representing the key of the data you want to retrieve.storeId
(optional): A string representing the ID of the store from which you want to retrieve data.
Returns: A promise that resolves with the value as a string or undefined
if the key does not exist.
Required permission: (opens in a new tab)
storage.get
Example:
async function getData(walletApiClient, key, storeId) {
try {
const value = await walletApiClient.storage.get(key, storeId);
console.log('Retrieved Value:', value);
} catch (error) {
console.error('Error retrieving data:', error);
}
}
2. Set Data
Store data in Ledger Live's internal storage. You can specify a key and value, and optionally provide a store ID to store data in a specific store.
walletApiClient.storage.set(key: string, value: string, storeId?: string): Promise<void>
Parameters:
key
(required): A string representing the key under which you want to store the data.value
(required): A string representing the data you want to store.storeId
(optional): A string representing the ID of the store where you want to store the data.
Returns: A promise that resolves when the data is successfully stored. There is no return value.
Required permission: (opens in a new tab)
storage.set
Example:
async function setData(walletApiClient, key, value, storeId) {
try {
await walletApiClient.storage.set(key, value, storeId);
console.log('Data successfully stored.');
} catch (error) {
console.error('Error storing data:', error);
}
}
Handling Errors
Make sure to handle errors gracefully and provide appropriate feedback to the user. Additionally, always remember to disconnect the WindowMessageTransport
when you're done interacting with the Ledger Wallet API to free up resources.
