Welcome to Taipy: A Comprehensive Introduction

Taipy is a robust and versatile open-source library designed for creating and managing data pipelines effortlessly. With a rich set of APIs, Taipy enables developers to perform complex data workflows seamlessly. In this guide, we will explore some of the most useful Taipy APIs along with code snippets, finishing off with an application example that brings everything together.

Key APIs in Taipy

1. Creating a Config

  from taipy.config import Config

  config = Config(node={
      "name": "start_node",
      "task": "start_task"
  })

2. Defining a Task

  from taipy.task import Task

  def start_task():
      print("Task started")

  task = Task(name="start_task", function=start_task)

3. Building a Data Node

  from taipy.data import DataNode

  data_node = DataNode(name="input_data_node", type="csv", filepath="data/input.csv")

4. Establishing a Pipeline

  from taipy.pipeline import Pipeline

  pipeline = Pipeline(
      name="sample_pipeline",
      nodes=[data_node],
      tasks=[task]
  )

5. Scheduling a Pipeline

  from taipy.schedule import Scheduler

  scheduler = Scheduler()
  scheduler.schedule(pipeline, cron="0 12 * * *")

Putting It All Together: A Sample Application

Let’s integrate the aforementioned components into a cohesive application.

  import taipy as tp
  from taipy.config import Config
  from taipy.task import Task
  from taipy.data import DataNode
  from taipy.pipeline import Pipeline
  from taipy.schedule import Scheduler

  # Initialize configuration
  config = Config(node={
      "name": "start_node",
      "task": "start_task"
  })

  # Define task
  def start_task():
      print("Processing data...")

  task = Task(name="start_task", function=start_task)

  # Create data node
  data_node = DataNode(name="input_data_node", type="csv", filepath="data/input.csv")

  # Build pipeline
  pipeline = Pipeline(
      name="sample_pipeline",
      nodes=[data_node],
      tasks=[task]
  )

  # Schedule the pipeline
  scheduler = Scheduler()
  scheduler.schedule(pipeline, cron="0 12 * * *")

  # Execute the pipeline
  print("Executing the Taipy pipeline...")
  tp.run(pipeline)

In this example, we have created a simple data pipeline that reads data from a CSV file and processes it. The pipeline is scheduled to run once daily at noon. By using Taipy’s structured framework, you can create highly complex data workflows with ease.
