Parsing URLs

To parse remote files, LiteParse supports both CLI and library usage for reading bytes and streams. The CLI can download them with any tool you like and pipe the bytes to lit parse using - as the file argument, while the libraries can fetch the bytes directly and pass them to the parser.

CLI usage

# Parse a remote PDF
curl -sL https://example.com/report.pdf | lit parse -

# With options
curl -sL https://example.com/report.pdf | lit parse --no-ocr --format json -

# Save to a file
curl -sL https://example.com/report.pdf | lit parse -o report.txt -

The - argument tells LiteParse to read from stdin instead of a file path. Any tool that writes to stdout works — curl, wget, aws s3 cp - -, etc.

Library usage

The TypeScript library accepts Buffer/Uint8Array directly, so you can handle the download however you like.

For example, using fetch in a Node.js environment:

import { LiteParse } from "@llamaindex/liteparse";

const response = await fetch("https://example.com/report.pdf");
const buffer = Buffer.from(await response.arrayBuffer());

const parser = new LiteParse({ ocrEnabled: false });
const result = await parser.parse(buffer);
console.log(result.text);
