Create Fungible Token in Solana - @solana/web3.js

1. Install Solana CLI

Install the Solana Tool Suite by running the following from a command-line shell:

sh -c "$(curl -sSfL https://release.solana.com/v1.15.2/install)"

See Solana Documentation

2. Create Command-Line Wallet

Create a command-line wallet (keypair) as a file system wallet. To generate a File System Wallet Keypair, run:

solana-keygen new --outfile <any-dir-for-wallets>/keypair.json

View the public key created in the keypair by running:

solana-keygen pubkey <path-to-wallet>/keypair.json

To view the private key created in the keypair, run:

cat <path-to-wallet>/keypair.json

Use this keypair as the payer and mint authority going forward.

Copy this private key and paste it in .env file in root directory
Content in .env should look like:

PRIVATE_KEY=[101,244,196,154,31,9,11,242...]

3. Create and transfer fungible tokens

Airdrop SOL into wallet by specifying public key.

solana airdrop <amount> <recipient_public_key>

OR

ts-node src/airdrop.ts <amount> <recipient_public_key>

Skip <recipient_public_key> argument to airdrop SOL into the wallet created earlier (private_key of which is stored in .env)
To check token balance in the specified wallet address (public key), run:

ts-node src/get-balance <public_key>

Create token mint

Run the following create a new token (mint):

ts-node src/create-token.ts

This writes the public_key of the mint into token-info.json

Create Associated Token Account and start Minting tokens

To start minting tokens using the mint created in the last step, an Associated Token Account for the mint needs to be created. Run the following in the CLI to create an ATA and mint 500 tokens into it.

ts-node src/create-ata-and-mint-tokens.ts

Add Metadata to the token

To view the token in Solana Explorer or other mobile/desktop wallets, we need to add metadata to the new token. Metadata include any arbitary name, symbol and description you choose along with a public url to an image.
Specify the metadata details in token-metadata.json file in the following format:

{
    "name": "Captain Levi Token",
    "symbol": "LEVI",
    "description": "I want to put an end to that recurring nightmare, right now. There are those who would get in my way. But I'm fine playing the role of the lunatic who kills people like that. I have to be ready to rearrange some faces. Because I choose the hell of humans killing each other over the hell of being eaten. --Levi Ackerman",
    "image": "https://avatars.githubusercontent.com/u/39588858?v=4"
}

Run the following to add metadata to the token.

ts-node src/addMetaData.ts

Transfer tokens to another wallet

Transfer any amount of tokens into any wallet by specifying the public_key of the recipient. Run:

ts-node src/transfer-token.ts <amount> <recipient_public_key>
#Example:
#ts-node src/transfer-token.ts 3 8H2zN6dWffQgPE6HDac1ZFL9HBL7C3Hx6SgY3qifiCXC

You should see success message in the terminal like:

 Trying transfer...
    Transaction Success!🎉
