 "title": "Write indexer output to a JSON snapshot instead of Postgres",
 "page_title": "How to write indexer output to a JSON snapshot instead of Postgres with Nuvex Services",
 "summary": "Point the indexer at a JSON read model path to capture decoded account data without running a database.",
 "who": "A developer or analyst who wants a file of decoded Nuvex program accounts for offline review and has no Postgres instance.",
 "problem": "Running PostgreSQL just to look at decoded accounts adds setup time. The indexer can write a JSON snapshot instead.",
 "outcome": "A JSON file at the path you set in NUVEX_READ_MODEL_PATH that contains rows decoded from known account layouts.",
 "steps": [
  "Run `pnpm install` in the repository root.",
  "Run `cp env/.env.local.example .env.local`, then set NUVEX_RPC_URL, one program id, and NUVEX_READ_MODEL_PATH.",
  "Start the indexer with the start command in the indexer section (not shown in the README, so check indexer/ first).",
  "Open the file at NUVEX_READ_MODEL_PATH and confirm it contains decoded rows, not placeholder data."
 ],
 "agent_prompt": "In the NuvexNetwork/nuvex-services repo, set NUVEX_RPC_URL, one program id, and NUVEX_READ_MODEL_PATH=<snapshot-path> in .env.local, run the indexer, then open the snapshot file. Report the number of top-level records and list the first record's keys. Verify that the indexer did not invent rows by comparing record count to the program accounts the RPC returned.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "1 hour",
 "basis": "readme",
 "caveat": "The README says the indexer does not invent rows but gives no snapshot schema, so the record structure must be read from the code.",

 "lang": "typescript",
 "requirements": [
  "Git and a clone of NuvexNetwork/nuvex-services",
  "pnpm and make, for `pnpm install` and `make check`",
  "A Solana-compatible RPC URL (NUVEX_RPC_URL or NUVEX_SOLANA_RPC_URL)",
  "At least one Nuvex program id (NUVEX_ORACLE_CORE_PROGRAM_ID, NUVEX_ORACLE_REGISTRY_PROGRAM_ID, or NUVEX_VERIFICATION_PROGRAM_ID)",
  "A PostgreSQL DATABASE_URL, or a NUVEX_READ_MODEL_PATH for a JSON snapshot"
