Methods
get(keyName) → {Promise.<ValueVersion>}
Look up the value of a specific key
Parameters:
| Name | Type | Description |
|---|---|---|
keyName |
String |
the key to lookup |

Example
// Assumes SAFEApp interface has been obtained
const asyncFn = async () => {
try {
const mData = await app.mutableData.newRandomPublic(15001);
await mData.quickSetup({ surname: 'Turing' });
const entries = await mData.getEntries();
const value = await entries.get('surname')
} catch(err) {
throw err;
}
};insert(keyName, value) → {Promise}
Insert a new entry. Once you call MutableData.put with this entry,
it will fail if the entry already exists or the current app doesn't have the
permissions to edit that MutableData.
Parameters:
| Name | Type | Description |
|---|---|---|
keyName |
String | Buffer | |
value |
String | Buffer |

const entriesArray = await entries.insert('given_name', 'Alan');
} catch(err) {
throw err;

};len() → {Promise.<Number>}
Get the total number of entries in the MutableData

const perms = await mData.getPermissions();
const length = await perms.len();
} catch(err) {
throw err;
}
};listEntries() → {Promise.<Array>}
Get a list with the entries contained in this MutableData

Example
// Assumes SAFEApp interface has been obtained
const asyncFn = async () => {
try {
const mData = await app.mutableData.newRandomPublic(15001);
await mData.quickSetup({ key1: 'value1', key2: 'value2' });
const entries = await mData.getEntries();
const entriesArray = await entries.listEntries();
entriesArray.forEach((entry) => {
const key = entry.key.toString();
const value = entry.value.buf.toString();
console.log('Key: ', key);
console.log('Value: ', value);
});
} catch(err) {
throw err;
}
};mutate() → {Promise.<EntryMutationTransaction>}
Create a new mutation transaction for the entries
