Automate Your Life: Building a Workflow Engine in TypeScript | Alfonso Graziano | jsday 2025

In a world full of repetitive tasks, why not automate the boring parts of your life? I'll show you how to build a custom Workflow Engine in TypeScript to streamline your day-to-day. We'll discuss practical applications and dive into the creation of multiple plugins, including integrations with IoT devices and Large Language Models, to handle complex tasks like crafting intelligent reminders, powering personalized routines, and even connecting with smart devices for seamless control.We'll start by breaking down the basics of workflow automation, then dive into fun, real-world examples that blend software, hardware, and AI. Perfect for developers ready to explore the power of TypeScript, hardware integration, and the magic of LLMs to automate our life, so you can focus on what matters.

Building a Workflow Engine in TypeScript Automate Your Life

Abstract

In today's world, repetitive tasks can be automated to make life easier. I'll guide you in building a custom Workflow Engine using TypeScript to simplify your daily routines. We'll explore practical uses and create various plugins, including connections with IoT devices and Large Language Models.

You will learn how to build a Workflow Engine that uses Directed Acyclic Graphs (DAGs), allowing for complex workflows with parallel tasks and decision-making paths. We'll explain how graph structures support automation, using algorithms like Depth-First Search for validation. You'll also learn to use recursive Promise chaining to handle tasks running at the same time and branching paths, ensuring workflows run smoothly.

We'll begin with the basics of workflow automation, then move to real-world examples that combine software, hardware, and AI. The goal of this talk is to give you a blend of useful theoretical foundations and practical tools to quickly build automations using Javascript or Typescript.

As cherry on the cake, we will look at how to build a dynamic plugin system to build your plugins and expand the capabilities of the base engine.
