how to create a fungible token using umi from Metaplex

Question

I have the following function, where I want to create a fungible token using UMI.

const metadata = {
    name: "Solana Gold",
    symbol: "GOLDSOL",
    uri: "https://raw.githubusercontent.com/solana-developers/program-examples/new-examples/tokens/tokens/.assets/spl-token.json",
};

const mint = generateSigner(umi);

async function createMetadataDetails() {
    await createV1(umi, {
        mint,
        authority: umi.identity,
        name: metadata.name,
        symbol: metadata.symbol,
        uri: metadata.uri,
        sellerFeeBasisPoints: percentAmount(0),
        decimals: 9,
        tokenStandard: TokenStandard.Fungible,
    }).sendAndConfirm(umi)
}

async function mintToken() {
    await mintV1(umi, {
        mint: mint.publicKey,
        authority: umi.identity,
        amount: 10_000,
        tokenOwner: umi.identity.publicKey,
        tokenStandard: TokenStandard.Fungible,
    }).sendAndConfirm(umi)
}

Currently It fails when calling mintV1. Error logs below.

  ],

}

I think the createV1 isn't creating the mint account as expected.

As I told you in my previous answer's comments, I found this function (createAndMint), on Metaplex GitHub repo, that might be what you were looking for... You can set the supply with it, and it happens that you don't need to use any of the other functions, just this one; you still need the metadata, of course.

The code would look like this:

const metadata = {
    name: "Solana Gold",
    symbol: "GOLDSOL",
    uri: "https://raw.githubusercontent.com/solana-developers/program-examples/new-examples/tokens/tokens/.assets/spl-token.json",
};

const mint = generateSigner(umi);

createAndMint(umi, {
    mint,
    authority: umi.identity,
    name: metadata.name,
    symbol: metadata.symbol,
    uri: metadata.uri,
    sellerFeeBasisPoints: percentAmount(0),
    decimals: 9,
    amount: 10_000,
    tokenOwner: umi.identity.publicKey,
    tokenStandard: TokenStandard.Fungible,
    }).sendAndConfirm(umi).then(() => {
    console.log("Some success message like: 0.00001 GOLDSOL (", mint.publicKey, ") minted");
});

I hope this helps

I believe you are having the same issue as myself few hours ago. When I tried minting a token I created I was get

ProgramNotRecognizedError: The provided program name [splAssociatedToken] is not recognized in the [devnet] cluster.

I solved this by installing Metaplex CandyShop plugin npm install @metaplex-foundation/mpl-candy-machine then proceed to adding the plugin to my umi instance

import { mplCandyMachine } from "@metaplex-foundation/mpl-candy-machine";

umi.use(mplCandyMachine())

I managed to make it work using this createFungible function:

createMetadataDetails().then(() => {
  createFungible(umi, {
    mint,
    authority: umi.identity,
    name: metadata.name,
    symbol: metadata.symbol,
    uri: metadata.uri,
    sellerFeeBasisPoints: percentAmount(0),
    decimals: 9,
  }).sendAndConfirm(umi).then(() => {
      mintToken();
});

});
