Type collected rows as BatchRowInput[].
The parser yields BatchRowInput, but rows is declared as unknown[]. Line 67 passes that array to processRows(rows: BatchRowInput[]). TypeScript rejects the call, which blocks declaration generation in the configured build. Preserve the parser’s row type when declaring the collection. (typescriptlang.org)

Route and write each row as it arrives.
This loop collects all rows before processRows runs, and the next loop writes results only after processing finishes. Even CSV input therefore produces no NDJSON output until EOF and retains the full batch in memory. Process each parsed row immediately, retain only its index and cumulative error flag, and write its result before reading the next row.

Report rows with a missing destination.
If a CSV or JSON row has an empty or missing destination, toBatchRow returns null. Both parsers then discard the row. The CLI emits no record for that row and can exit with code 0, although the row has a fatal address error. Preserve the row index and emit an error record instead of dropping the row.

Do not convert JSON numeric memo IDs after parsing.
If JSON contains {"memoType":"id","memoValue":9007199254740993}, JSON.parse has already rounded that number before String(memoValueRaw) runs. Batch routing can therefore use a different memo ID from the input. Require string memo values, or parse numeric tokens without a precision-losing conversion.

Mark unroutable routing results as errors.
extractRouting can return destinationError or destinationBaseAccount: null without throwing. This branch still sets ok: true, so processRows leaves hasErrors false and the CLI can exit with code 0 for an unroutable deposit. Classify those returned results before setting ok and the batch error flag.

Use the declared readline interface.
Line 125 declares rii, but this loop reads rli. TypeScript cannot resolve rli, so declaration generation fails. If emitted JavaScript runs, CSV input also fails before the first row. Use the same identifier in both places. (nodejs.org)
Proposed fix
- for await (const line of rli) {
+ for await (const line of rii) {📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Process JSON input without buffering the entire stream.
chunks retains every line before parsing starts. A large or continuing NDJSON stream produces no results until EOF and can exhaust memory. Parse NDJSON records as they arrive; use an incremental parser if JSON arrays must also support streamed processing.

Report malformed NDJSON lines.
If one NDJSON line contains invalid JSON, this catch discards it and processing continues. The CLI emits no record for that input row and can report success. Emit an indexed error record and set the batch error flag instead of silently skipping the line.

Detect JSON when input comes from stdin.
runBatch(null) calls detectFormat(null), which always returns "csv". A JSON object or NDJSON record sent through --stdin is treated as a CSV header; it produces no result and exits successfully. Detect the format from buffered initial input bytes, then pass those bytes to the selected parser.

Wait when the output stream applies backpressure.
If stdout is a slow pipe, stream.write() can return false. The CLI continues writing every record, so Node.js buffers output without a practical bound and can exhaust memory. Make the writer await 'drain' and have the batch loop await the writer. (nodejs.org)

Overview
This PR adds batch processing to the
stellar-routeCLI. It introduces--file <path>and--stdinflags that accept CSV or JSON transaction dumps, stream inputs, and emit results as Newline Delimited JSON (NDJSON). The CLI now exits with code1when any fatal address errors or unroutable deposits are encountered, and0on success — enabling DevOps engineers and auditors to pipe transaction dumps directly into the tool for bulk deposit verification.Related Issue
