open-lineage-client-js v0.2.4

Project Name

Overview

This project is supposed to offer a similar functionality as the Python and Java Open Lineage Clients so creation and transportation of the OL events.

Features

• Event creation and serialization
• ConsoleTransport
• HTTPTransport
• File Config
• CI

Installation

To install the project dependencies, run: npm install

Usage

Event Creation

• create a new instance of the LineageEvent (Run, Job, Dataset) using the provided Builder classes for the event itself and its Facets

const event = new RunEventBuilder(new Date().toISOString(), producer,
   schemaURL, EventType.START)
  .setRun(run)
  .setJob(job)
  .setInputs([inputDataset])
  .setOutputs([outputDataset])
  .build();

ConsoleTransport

• create a new instance of the LineageClient it will have the console transport by default
• pass your event to the emit method of the client

const client = new OpenLineageClient(producer, new ConsoleTransport());
client.emit(event);

HTTPTransport

• create a new instance of the LineageClient with the HTTP transport
• pass your event to the emit method of the client

const transport = new HttpTransport(new HttpConfig("http://localhost:5000/api/v1/lineage"));
const client = new OpenLineageClient("https://example.com", transport);
client.emit(event);

File Config

• create a new config yaml file named 'openlineage.yaml' in root of the project
• example of simple http transport config

transport:
  type: http
  config:
    url: http://localhost:5000/api/v1/lineage 

• create a new instance of the LineageClient without providing the transport it will be automatically loaded from the file if file is present

    const client = new OpenLineageClient("https://example.com");
    client.emit(event);

Testing

To run the tests, use the following command: npm test
