NodeJS WASM loading async but calls maybe faster than async loading complete

[dmikey]

Executing lit-js-sdk in an environment where a method will be executed before the wasm completes to load, will result in a

[Lit-JS-SDK] wasmExports is not loaded. error.

the promise is returned after the main thread is idle.

simple recreation

const LitJsSdk = require("lit-js-sdk");

const { verified, header, payload } = LitJsSdk.verifyJwt({
  jwt: "",
});

simple work around

const LitJsSdk = require("lit-js-sdk");

function checkLitWasm() {
  if (!globalThis.wasmExports) {
    setTimeout(
      checkLitWasm,
      100
    ); /* this checks the flag every 100 milliseconds*/
  } else {
    const { verified, header, payload } = LitJsSdk.verifyJwt({
      jwt: "",
    });
    console.log(verified, header, payload);
  }
}
checkLitWasm();
