The parsing engine that detects inscriptions in Bitcoin transactions. The compiled code has zero dependencies and works in the Browser and in Node.js out of the box.
The latest version of this script is used by https://ordpool.space
This package has zero dependencies and should "just work". First, install it:
npm install ordpool-parser
Then, you can use the parser in your project. It expects a transaction from the Mempool API:
import axios from 'axios';
import { InscriptionParserService } from 'ordpool-parser';
async function getInscriptions(txId: string) {
const response = await axios.get(`https://mempool.space/api/tx/${txId}`);
const transaction = response.data;
return InscriptionParserService.parseInscriptions(transaction);
}
const parsedInscriptions = await getInscriptions('f1997166547da9784a3e7419d2b248551565211811d4f5e705b685efa244451f');
if (!parsedInscriptions.length) {
console.log('No inscriptions found!');
} else {
// Output: text/html;charset=utf-8
console.log(parsedInscriptions[0].contentType);
// UTF-8 encoded string (not intended for binary content like images or videos)
// Output: <html><!--cubes.haushoppe.art--><body> [...]
console.log(parsedInscriptions[0].getContentString());
// Base64 encoded data URI that can be displayed in an iframe
// Output: data:text/html;charset=utf-8;base64,PGh0bWw+PCEtLWN1YmVzLmhhdXNob3BwZS5hcnQtLT48Ym9keT4 [...]
console.log(parsedInscriptions[0].getDataUri());
}This example uses axios, a popular HTTP client for both browser and Node.js environments.
You can install it via npm install axios. Of course, any other compatible HTTP client will also work.
Note: This is a simplified example! Make sure to handle errors when making HTTP requests, as network issues can occur.
Node.js (Version 20 or later) to test & compile the TypeScript code to JavaScript.
First, install Node.js version 20. Then, install the NPM dependencies and execute the tests with the following commands:
npm install
npm testEvery feature must be tested in the browser and in the node environment! Use a mainnet transaction to create a test scenario. The goal of this parser is to parse byte-perfect inscriptions that are identical to ord.
-
Fetch Transaction Test Data: Save the raw transaction JSON to the
testdatafolder.npm run fetch-tx-testdata
Enter the
transactionId(e.g.78fa9d6e9b2b49fbb9f4838e1792dba7c1ec836f22e3206561e2d52759708251) and check the results. -
Fetch Inscription Test Data: Save the reference inscription as a file in the
testdatafolder.npm run fetch-inscription-testdata
Enter the
inscriptionId, which is thetransactionId+i+ theindex(e.g.78fa9d6e9b2b49fbb9f4838e1792dba7c1ec836f22e3206561e2d52759708251i0), and check the results! -
Contribute: Add your new feature, include meaningful tests, and submit a pull request if all tests pass.
-
Hint: Debug the unit tests using VS Code. The
launch.jsonfile is already prepared for this purpose.
To build a version without the tests:
npm run buildTo publish a new version to NPM:
npm run publish- Ordpool: https://ordpool.space
