Connecting to Lite RPC from Web3 Node.js Application

[datacoder-io]

Hello Lite RPC Team,

I've recently set up a Solana RPC node on my server and am now looking to enhance transaction handling using Lite RPC. I successfully built and ran Lite RPC using cargo run --release, and everything appears to be functioning correctly.

Here's the configuration I used for Lite RPC:

{ "rpc_addr": "http://127.0.0.1:8899", "ws_addr": "ws://127.0.0.1:8900", "lite_rpc_http_addr": "[::]:8890", "lite_rpc_ws_addr": "[::]:8891", "fanout_size": 18, "identity_keypair": null, "prometheus_addr": "[::]:9092", "maximum_retries_per_tx": 40, "transaction_retry_after_secs": 3, "quic_proxy_addr": null, "use_grpc": false, "calculate_leader_schedule_from_geyser": false, "grpc_addr": "http://127.0.0.1:10000", "grpc_x_token": null }

I am now trying to connect to Lite RPC from a Web3 Node.js application. My initial attempt to establish a connection was as follows:

const connection = new Connection("http://127.0.0.1:8890", { commitment: 'confirmed' });

Unfortunately, this does not seem to work, and the connection isn't established. I've looked for documentation or examples on how to properly connect to Lite RPC from a Web3 context but haven't found any resources that address this specific use case.

Could you provide any guidance or examples on how to establish this connection? Are there any specific configurations or steps that I'm missing?

Thank you in advance for your assistance. I'm looking forward to integrating Lite RPC into our setup to leverage its capabilities for better transaction processing.

We have a test in test/client-test.ts which was working a while back. But seems that it has stopped working for lite-rpc. Probably because web3.js has evolved somehow.

We will fix it and renable the test duing deployment.

After testing this bug is related to the version of jsonrpsee.

It will be solved when we update the jsonrpsee version.

Hi @datacoder-io ,

this code worked for me using version solana/web3.js@1.91.7 and my dev version of lite-rpc:

async function main() {

        const web3 = require("@solana/web3.js");

        let connection = new web3.Connection("http://127.0.0.1:8890", { commitment: 'confirmed' });

        let slot = await connection.getSlot();
        console.log(slot);
        // 263047157
}

main();

do you still get the connection errors?

@grooviegermanikus what dev branch did you try that on? thanks

[grooviegermanikus]

@DutchKevv retested with this d10910e73 and it worked well

what error do you get?

Dude not sure if this has something to do with it, but I cloned your repo, run it and I got fully drained on multiple wallets..
