Monitor Module
The Monitor Module is useful to poll for changes, e.g. on the blockchain, especially for confirmations of transactions.
This module is still in an experimental stage
npm
yarn
<script/>
npm i @signumjs/monitor
yarn add @signumjs/monitor
<script src='https://cdn.jsdelivr.net/npm/@signumjs/monitor/dist/signumjs.monitor.min.js'></script>
The namespace is
sig$monitor// Create an account monitor
const monitor = new sig$monitor.Monitor({
asyncFetcherFn: tryFetchAccount,
compareFn: checkIfAccountExists,
intervalSecs: 10, // polling interval in seconds
key: 'monitor-account',
timeoutSecs: 2 * 240 // when reached timeout the monitor stops
})
.onFulfilled(() => {
// called when `checkIfAccountExists` returns true
console.log('Yay, account active');
})
.onTimeout(() => {
// called when `timeoutSecs` is reached
console.log('Hmm, something went wrong');
}).start();
