Connect to db3 network with db3 browser wallet
// the key seed
const mnemonic ='...'
// create a wallet
const wallet = DB3BrowserWallet.createNew(mnemonic, 'DB3_SECP256K1')
// build db3 client
const client = new DB3Client('http://127.0.0.1:26659', wallet)Connect to db3 network with metamask
const wallet = new MetamaskWallet(window)
const client = new DB3Client('http://127.0.0.1:46659', wallet)const [dbId, txId] = await client.createDatabase()
const {db} = initializeDB3('http://127.0.0.1:26659', dbId, wallet)// add a index to collection
const indexList: Index[] = [

// create a collecion
const collectionRef = await collection(db, 'cities', indexList)
// add a doc to collection
