I am trying to get some bitcoin network data and I am using bitcoind-rpc library. If i just run their example:

var run = function() {
  var bitcore = require('bitcore');
  var RpcClient = require('bitcoind-rpc');
  var config = {
    protocol: 'http',
    user: 'user',
    pass: 'pass',
    host: '',
    port: '18332',
  // config can also be an url, e.g.:
  // var config = 'http://user:[email protected]:18332';
  var rpc = new RpcClient(config);
  var txids = [];
  function showNewTransactions() {
    rpc.getRawMemPool(function (err, ret) {
      if (err) {
        return setTimeout(showNewTransactions, 10000);
      function batchCall() {
        ret.result.forEach(function (txid) {
          if (txids.indexOf(txid) === -1) {
      rpc.batch(batchCall, function(err, rawtxs) {
        if (err) {
          return setTimeout(showNewTransactions, 10000);
        rawtxs.map(function (rawtx) {
          var tx = new bitcore.Transaction(rawtx.result);
          console.log('\n\n\n' + tx.id + ':', tx.toObject());
        txids = ret.result;
        setTimeout(showNewTransactions, 2500);

I need to provide the data of my local node.

But I have problems downloading bitcoin node mostly because I do not have enough space.

Is there another way I can access the node without downloading full node localy?

    You can use pruned node if space is an issue.

    The RPC interface is way of interacting with your Bitcoin node. If you don't run one, then no, you can't just use someone else's. But as @Prayank says, you can run a pruned node, which has lower disk requirements. There are other solutions if you're willing to trust someone else's node, but they involve other protocols than RPC. Commented Sep 12, 2021 at 15:46

Since you mention nodejs you might be interested in bcoin:



Bcoin is modular and configurable in weird ways. See this other answer on how bcoin can be modified to download arbitrary blocks even in pruned mode:

How do I get old blocks while running a pruned node?
