cardano-serialization-lib-gc
This is a small ESM library that provides a wrapper for managing garbage collection for cardano-serialization-library. It does this by using a FinalizationRegistry
object to keep track of objects that are no longer in use, and calling the free()
method on them when they are finalized.
Example usage with NodeJS:
import * as lib from "@mlabs-haskell/cardano-serialization-lib-gc";
function fixture() {
lib.PlutusData.new_bytes(
new Uint8Array(Array(10000000).fill(0))
);
}
setInterval(() => {
for (let i = 0; i < 10; i++) {
fixture()
}
}, 500) // collection of unused objects will trigger `free()` calls
// for the corresponding WASM-allocated memory
This code will not leak, but if you try to use the original package, the memory usage will steadily grow.
If you want to use this library as a CommonJS module, use legacy csl-gc-wrapper instead.
