The liquidityFile is too large. Is there a faster way to get the poolInfo from two tokens?

[y0unghe]

Whenever the swap executes the program will call the following codes to get the poolInfo to load the liquidity file. The file is 467MB. Is there a better and faster way to get the poolInfo?

await raydiumSwap.loadPoolKeys(Raydium_Liquidity_File);

let poolInfo = raydiumSwap.findPoolInfoForTokens(sourceToken, destinationToken);

You are right , did you find any other way to find be poolInfo faster ?

Hey guys, a valid point. I updated the project to only use the trimmed version. Check the TLDR quick run section as it has the details https://github.com/chainstacklabs/raydium-sdk-swap-example-typescript/blob/main/README.md#tldr-quick-run

Unsure if this is OS specific or not, I'm using Arch Linux and Node v22.8.0. Looks like the file is just too big for Node.js at >512MiB.

In my main project I'm using JSONStream to load the JSON in chunks rather than loading the full file at once. Maybe something similar should be done for the trim script?
