Client helpers: CreateMint (javascript)

[grod220]

Creating a js client library for calling the CreateMint instruction (1 of 3 total). Attempts to use solana kit as the base library.

Walkthrough for testing locally:

1. Build program

cargo build-sbf # generates .so file
cargo build # builds binary

2. Start solana test validator

solana-test-validator \
  --bpf-program TwRapQCDhWkZRrDaHfZGuHxkZ91gHDRkyuzNqeU5MgR target/deploy/spl_token_wrap.so \
  --reset

3. Create a new mint & token account

spl-token create-token
# Example will have G85DDQCoHchhDFWtUFT2MDkfUPYQt8BvViFyjGv167xb for this
spl-token create-account G85DDQCoHchhDFWtUFT2MDkfUPYQt8BvViFyjGv167xb
spl-token mint G85DDQCoHchhDFWtUFT2MDkfUPYQt8BvViFyjGv167xb 100000

4. Update token-wrap/clients/js/example.ts with your keypair + unwrapped mint address generated above

5. Install deps

cd ./token-wrap/clients/js
pnpm install

6. Run example

pnpm example:create-mint

7. See expected output
