Sri Lankan Passport OCR with Node.js SDK

Extracting Data from Sri Lankan Passports

Sri Lankan passports combine printed identity fields, dates and a machine-readable zone on a security-patterned page. Capture quality, glare and perspective can make manual entry or plain text OCR difficult to use in a repeatable backend workflow.

Passport Extraction with the Node.js SDK

The StructOCR passport endpoint returns normalized passport fields from a readable Base64-encoded image or PDF. Your application can use the result to pre-fill a form or send it to a review step without maintaining its own field-parsing rules.

Common Integration Scenarios

• Travel onboarding: Pre-fill passport details before the traveller confirms them.
• Customer records: Move visible identity and expiry information into an internal review workflow.
• Document intake: Return consistent JSON to a small-volume application or operations team.

Sri Lankan Passport OCR with Node.js SDK

The official Node.js SDK reads a supported local file and calls /v1/passport. Open the TypeScript + Express tab for a server route using the same SDK method.

Prerequisite: `npm install structocr`; set the server-side `STRUCTOCR_API_KEY` environment variable.

Prefer another stack? Open the Python SDK + FastAPI integration.

const StructOCR = require("structocr");

const client = new StructOCR(process.env.STRUCTOCR_API_KEY);

async function main() {
  const result = await client.scanPassport("passport.jpg");

  if (result.success) {
    const data = result.data;
    console.log(data.document_number || data.passport_number);
    console.log(data.given_names, data.surname);
  } else {
    console.error(result.error);
  }
}

main().catch(console.error);
