How to initialize a fungible store for a Fungible asset via TypeScript?

From unbound on Discord:

Can I have something in typescript that allows the signer on the frontend to quickly initialize a fungiblestore for them of a certain metadata?

You can call 0x1::primary_fungible_store::create_primary_store if you're looking for a fungible asset, but it's not an entry function on it's own.

Additionally, 0x1::primary_fungible_store::transfer will create the primary fungible store, similar to coin.

    const metadataAddress = "0x12345";
    const recipientAddress = "0x1337";
    const amount = 0;

    const txn = await aptos.transaction.build.simple({
        sender: account.accountAddress,
        data: {
            function: "0x1::primary_fungible_store::transfer",
            typeArguments: ["0x1::object::ObjectCore"],
            functionArguments: [metadataAddress, recipientAddress, amount],
        }
    });

Does that answer your question, or are you looking for something else?

Initially I had a parameter on my modules function that was an Object where some funds will get withdrawn from the module. If a user did not have that fungible asset in the account already, they couldn't call that function. I've changed it in the meantime to take an Object and then I create a fungible store for them on chain and deposit in that store.
That code above doesn't exactly fix the issue, but thanks for the help!

Can you share this code to fix the issue?

pfs::ensure_primary_store_exists returns the account's primary store, and creates one and returns it if it doesn't exist.
