Node.js Nanowire Library

This is a node.js library which provides a wrapper around Nanowire's controller service. It allows the user to easily fetch and process tasks from Nanowire's pipeline. If you are starting a new project from scratch it is recommended that you use the Nanowire Python Skeleton Plugin as the basis for your plugin as it is already set up and ready to use.

Details on how to run

First install the dependencies with:

yarn install

The following environment variables need to be set:

CONTROLLER_BASE_URI
POD_NAME
PLUGIN_ID

Then the library can be built with:

yarn build

Usage

import SpotlightPipeline from '@spotlightdata/nanowire-plugin-js';
import { name as pluginName } from '../package.json';

const processMessage = async (nmo, jsonld, url) => {
  return {
    '@type': 'TextDigitalDocument',
  };
};

const client = new SpotlightPipeline({
  taskHandler: processMessage,
  pluginName,
});

client.start();

Task handling

Your handler function must take 3 parameters, 1 the NMO, 2 the jsonld (if any otherwise this will be undefined) and 3 a Minio presigned URL which you can use to get the original file.

Your function must return the JSON-LD that you want to be stored/passed along.
