Hi. This is Freighter Wallet javascript code.
I try to find a way to get publicKey outside of this code.
when I console.log(publicKey) after "await" everything ok. But I can't set publicKey to other variables to use outside of this code. When I set a variable after "await" and use it outside it is just undefined.
result log gives me "promise pending". I can use "then" to get results on "console.log" . but still don't know any way to set the result to a variable to use.

You can define a global variable at the top:
var publicKey;
(remove the line
let publicKey = "";
)
and set it like you do already:
publicKey = await window.freighterApi.getPublicKey();
But it will still be available only after the
retrievePublicKey
has run; it's an
async function
so you have to await it, and that cannot be done from the 'main' method (just
await retrievePublicKey()
won't work). You can do it with
then
, as you already tried, or a self-invoked async function as described
in this Stack Overflow answer
.
