basic

basic example — Node + Viem

Minimal Node script that builds a viem-error-parser decoder, throws a few synthetic errors at it, and prints what comes out.

Run

pnpm install
pnpm run start

You should see something like:

[1] ERC20InsufficientBalance(sender=0x..., balance=5n, needed=100n)
[2] Reverted: deadline expired
[3] Panic: Arithmetic overflow or underflow. (code 0x11)
[4] The transaction was rejected by the user.
[5] Unknown error.

The fixtures live in index.ts — feel free to swap in real errors you've caught in production.
