Provides you with an HucAccounts
collection, where balances are automatically updated.
Additionally the accounts are persisted in localstorage.
If the ethereum node removes accounts,
the HucAccounts
collection will set the deactivated: true
property to these accounts and hide them from normal queries.
If the Accounts should reapear in the node (e.g. the user importet those, or mist allwed them access), they will be available again, including all the extra properties you've set.
Note don't use the HucAccounts
collection to add your own custom accounts as a reload of your application,
or any change in web3.eth.accounts
would hide them.
$ meteor add ethereum:accounts
Initialize Accounts on the start of your application, as soon as you have a ethereum connection:
EthAccounts.init();
Then simply use the global HucAccounts
object like any other minimongo collection.
It provides the .find()
, .findOne()
, .findAll()
, .update()
, .updateAll()
and .remove()
functions e.g.:
// Get all active accounts
var myAccounts = EthAccounts.find().fetch();
[
{
"_id": "2Zd3Z9XQrc7iN7Ci3"
"address": "0x343c98e2b6e49bc0fed722c2a269f3814ddd1533",
"balance": "18260939861619682985678",
"name": "Coinbase",
}
]
// or
var myPrimaryAccount = EthAccounts.findOne({name: 'Coinbase'});
var allAccounts = EthAccounts.findAll().fetch();
[
{
"_id": "2Zd3Z9XQrc7iN7Ci3"
"address": "0x343c98e2b6e49bc0fed722c2a269f3814ddd1533",
"balance": "18260939861619682985678",
"name": "Coinbase",
},
{
"_id": "56sbC8dggbYstmN2o",

"balance": "0",
"name": "0x990ccf8a0de58091c028d6ff76bb235ee67c1c39",
"deactivated": true
}
]
EthAccounts.updateAll({address: "0x990ccf8a0de58091c028d6ff76bb235ee67c1c39"}, {name: 'XYZ'}});
EthAccounts.updateAll(
{ address: "0x990ccf8a0de58091c028d6ff76bb235ee67c1c39" },
{ $unset: { deactivated: "" } }
);
