A plug and play Bitsocket connection for Nodejs and browser.
The latest version of bitsocket-connect no longer uses the callback method when crawling the event database. The api use to be crawlRecent(token, query, processFunction, callback, endPoint). Instead crawlRecent is an async function and so you can use .then() or async await.
npm i --save bitsocket-connect
in the browser include the following script tag in your document header (crawlRecent not supported in the browser) :
<script type="text/javascript" src='https://x.bitfs.network/58e08db775da80c45f82ec4c28204aa228140c32c2d1aaa8b5911e5b8d57f9f5.out.0.3'></script>
bitsocket-connect includes 3 functions to interface with Bitsocket; connect, getLatest, and close. Use crawlRecent to crawl the last 24 hours of transactions.
query: A TXO query used to filter new transactions.
process: A function that is called individually on each incoming transaction from Bitsocket and is passed the transaction as a parameter. Can be synchronous or async but if it is async be sure to return a promise that resolves when done processing the transaction to ensure all transactions are processed in the correct order.
lastEventId: Use the Last-Event-Id from close() to reopen a Bitsocket from where you left off.
endPoint: Bitsocket endpoint. defaults to TXO
example:
in node:
const bitsocket = require('bitsocket-connect');
node and browser:
const query = { "v": 3, "q": { "find": {} } };
bitsocket.connect(query, function(tx){
console.log(tx)
});
Closes the Bitsocket and returns the Last-Event-Id in case you would like to reopen the socket or null if there is none.
Gets the latest transaction matching your query that was received by the Bitcoin network before opening the Bitsocket. This can either be a confirmed or unconfirmed transaction.
example:
bitsocket.getLatest().then(latest=>console.log(latest));
Crawls the last 24 hours of the Bitsocket event database. Uses the same api as run-bitbus
Have fun!
