verifier-like example

Minimal example: Parser (SHiP → Redis indexer) and ParserClient (consumer) running in the same Node.js process. The consumer watches native permission table deltas and logs every account-key change.

Prerequisites

• Node.js 20+
• pnpm 9+
• Redis 7+ (with appendonly yes)
• Access to an EOSIO/Antelope node with SHiP plugin enabled

5-step startup

Step 1 — Clone and install

git clone https://github.com/coopenomics/parser2.git
cd parser
pnpm install

Step 2 — Build the package

pnpm --filter @coopenomics/parser2 build

Step 3 — Configure

cp examples/verifier-like/.env.example examples/verifier-like/.env
# Edit .env: set SHIP_URL, CHAIN_ID, REDIS_URL, SUB_ID

Step 4 — Start Redis (if not already running)

docker run -d --name redis -p 6379:6379 redis:7-alpine redis-server --appendonly yes

Step 5 — Run the example

cd examples/verifier-like
pnpm start

Expected output:

Starting verifier-like example for chain: eos-mainnet
[400000000] permission UPSERT: eosio@active {"threshold":1,"keys":[...]}
[400000001] permission UPSERT: alice@owner {"threshold":1,"keys":[...]}

Stopping

Press Ctrl+C — the process performs a graceful shutdown (drains in-flight messages, closes Redis connection).
