Effect-Ts on Dev & Platform Engineering Hub

TS Ep 70: Building a REST API with Effect

Sun, 09 Aug 2026 15:55:00 +0000

We assemble the ultimate functional backend. Learn how to combine Layers, Context, Schema Validation, Error Handling, and Resource Management into a massive, production-grade Express REST API using @effect/platform.

TS Ep 69: Managing Resources and Scope

Sun, 09 Aug 2026 15:50:00 +0000

Learn how to safely acquire and release resources like database connections and file streams. The Scope API replaces try/finally blocks, guaranteeing cleanup even if your application crashes.

TS Ep 68: Effect Schema Validation

Sun, 09 Aug 2026 15:45:00 +0000

TypeScript interfaces do not exist at runtime. To protect your application from malformed API payloads and corrupted database rows, learn how to use @effect/schema to parse and validate data perfectly.

TS Ep 67: Concurrency and Fibers

Sun, 09 Aug 2026 15:40:00 +0000

Learn how Effect-TS implements Fibers (green threads) to allow millions of concurrent operations. Master Effect.all, concurrency limits, and safe interruption of background tasks.

TS Ep 66: Layers & Service Wiring

Sun, 09 Aug 2026 15:35:00 +0000

Providing single services is easy, but enterprise applications have massive dependency graphs. Learn how to use Effect Layers to wire services together, handle async initialization, and resolve graphs perfectly.

TS Ep 65: Context & Dependency Injection

Sun, 09 Aug 2026 15:30:00 +0000

Eliminate global singletons and complex IoC containers. Learn how the R parameter in Effect<A, E, R> forces you to provide dependencies before your program can run, ensuring perfect testability.

TS Ep 64: Error Handling in Effect

Sun, 09 Aug 2026 15:25:00 +0000

Effect-TS completely reimagines error handling. Learn the difference between Expected Failures and Unexpected Defects, and how to use catchTag to build resilient, self-documenting pipelines.

TS Ep 63: Creating and Running Effects

Sun, 09 Aug 2026 15:20:00 +0000

To use Effect-TS, you must know how to bridge the gap between the chaotic outside world and your pure functional pipeline. Master the constructors and execution methods of the Effect runtime.

TS Ep 62: The Effect Type Signature

Sun, 09 Aug 2026 15:15:00 +0000

The heart of Effect-TS is its three-parameter type signature. Master the A (Success), E (Error), and R (Requirement) parameters to unlock perfect architectural safety.

TS Ep 61: Introduction to Effect-TS

Sun, 09 Aug 2026 15:10:00 +0000

We have built the functional foundation. Now it is time to enter the ecosystem. Discover why Effect-TS is rapidly becoming the standard library for enterprise TypeScript, and run your first pure asynchronous program.

TS Ep 60: Function Composition (Pipe & Flow)

Sun, 09 Aug 2026 15:05:00 +0000

Learn how to avoid the ‘Pyramid of Doom’ and method chaining limitations by embracing functional composition. We explore how pipe and flow allow you to build complex logic from small, testable pure functions.

TS Ep 59: Monadic Patterns (Option & Either)

Sun, 09 Aug 2026 15:00:00 +0000

Learn how to wrap missing data and expected errors in type-safe containers. We explore the Option and Either monads, providing the final foundational step before entering the Effect-TS ecosystem.

TS Ep 58: Algebraic Data Types (ADTs)

Sun, 09 Aug 2026 14:55:00 +0000

Learn how to eliminate impossible states from your application by mastering Algebraic Data Types (ADTs). We explore Sum Types, Product Types, and exhaustive pattern matching in TypeScript.

TS Ep 57: Immutability & Readonly Data

Sun, 09 Aug 2026 14:50:00 +0000

Functional programming requires data to be immutable. Discover how to leverage TypeScript’s structural typing, Readonly<T>, and as const to enforce deep immutability at compile time, eliminating a massive category of state-based bugs.

TS Ep 56: Functional Programming Basics & Pure Functions

Sun, 09 Aug 2026 14:45:00 +0000

Welcome to the final module! Before diving into Effect-TS, we must build a foundation in Functional Programming. Learn why pure functions eliminate whole classes of bugs, how separating descriptions from execution powers the Effect runtime, and how to refactor impure services into highly testable functional pipelines.

TS Ep 4: Functional TypeScript & Effect-TS Prelude — Immutability, ADTs, and Type-Driven Error Handling

Sun, 09 Aug 2026 14:00:00 +0000

The functional programming masterclass for TypeScript developers. Bridge object-oriented patterns into pure functional architecture with Option/Either types, typed error handling without throw exceptions, pipe/flow composition, and an introduction to the Effect-TS ecosystem.

Mastering TypeScript: From Fundamentals to Type-Level Programming & Functional Effect-TS

Sun, 09 Aug 2026 12:00:00 +0000

The ultimate TypeScript masterclass roadmap. Master primitive types, type narrowing, generics, mapped types, conditional types, infer keyword, template literal types, type-level state machines, and functional Effect-TS architecture.
