Effect Module Request

Owned scope

Owns only

Source of truth:

.

What it is for

The
```
Request
```
module provides a way to model requests to external data sources in a functional and composable manner. Requests represent descriptions of operations that can be batched, cached, and executed efficiently.

How to use it

Start with constructor-style APIs to build values/services before composing operations.
Use the reference docs to select the smallest API surface that solves your task.
Validate behavior against existing tests before introducing new usage patterns.

Starter example

import type { Request } from "effect";

// Define a request that fetches a user by ID
interface GetUser extends Request.Request<string, Error> {
  readonly _tag: "GetUser";
  readonly id: number;
}

// Define a request that fetches all users
interface GetAllUsers extends Request.Request<ReadonlyArray<string>, Error> {
  readonly _tag: "GetAllUsers";
}

Common pitfalls

Prefer explicit, typed combinators over ad-hoc casting or unchecked assumptions.

Not covered here

Adjacent modules in
```
effect/*
```
and
```
effect/unstable/*
```
are out of scope for this owner.

Escalate to

```
effect-skill-router
```
for routing and ownership checks.
