When to use
Use to model construction of application services for dependency injection,
especially when services have dependencies, can fail during construction, or
need scoped setup and release.
Details
A Layer<ROut, E, RIn> represents ROut as the services this layer
provides, E as the possible errors during layer construction, and RIn as
the services this layer requires as dependencies.

Hyperlink.layer
/
serve
) — never by
Hyperlink.client
. Local to this runtime's materialized impl for the tag (not a remote
client, not a peer). A
LocalMethod
carries it in its requirement channel, so calling a
non-serializable method against a client is a compile error (unsatisfied requirement); the
same call resolves when the local layer is provided. Branded by Self so one HyperService's local
layer can't unlock another's.
Local<function (type parameter) Self in serve<Self, S extends Spec, A = void, E = never, R = never>(tag: HyperlinkTag<Self, S>, config: DaemonLayerConfig<A, E, R>): Layer.Layer<Self | Local<Self> | HandlerContextOf<DaemonSpec> | Store.Storage, never, R>Self> | type HandlerContextOf<S extends Spec> = RpcUnionOf<S, ""> extends Rpc<infer _Tag extends string, infer _Payload extends Schema.Top, infer _Success extends Schema.Top, infer _Error extends Schema.Top, infer _Middleware extends AnyService, infer _Requires> ? Handler<_Tag> : neverThe context a server layer for a

provides: the handler for every method.
Used to pin the server layers' output type so their requirement channel stays
never — RpcGroup's own ToHandlerFn defaults that channel to any, so without
this the inferred server layer would re-leak any into anything that consumes it.

Unwraps a Layer from an Effect, flattening the nested structure.
When to use
Use when you have an Effect that produces a Layer and you want to
use that layer directly.
Details
The resulting Layer will have the combined error and dependency types from
both the outer Effect and the inner Layer.
Example (Unwrapping an effectful layer)
import { Context, Effect, Layer } from "effect"
class Database extends Context.Service<Database, {
readonly query: (sql: string) => Effect.Effect<string>
}>()("Database") {}
const layerEffect = Effect.succeed(
Layer.succeed(Database, { query: Effect.fn("Database.query")((sql: string) => Effect.succeed("result")) })
)
const unwrappedLayer = Layer.unwrap(layerEffect)
unwrap(
import EffectEffect.const map: {
<A, B>(f: (a: A) => B): <E, R>(
self: Effect<A, E, R>
) => Effect<B, E, R>
<A, E, R, B>(
self: Effect<A, E, R>,
f: (a: A) => B
): Effect<B, E, R>
}
Transforms the value inside an effect by applying a function to it.
When to use
Use to transform an effect's success value with a function that returns a
plain value, producing a new effect without changing the original effect's
typed error or context requirements.
Details
map takes a function and applies it to the value contained within an
effect, creating a new effect with the transformed value.
It's important to note that effects are immutable, meaning that the original
effect is not modified. Instead, a new effect is returned with the updated
value.
Example (Choosing map syntax variants)
import { Effect, pipe } from "effect"
const myEffect = Effect.succeed(1)
const transformation = (n: number) => n + 1
const mappedWithPipe = pipe(myEffect, Effect.map(transformation))
const mappedWithDataFirst = Effect.map(myEffect, transformation)
const mappedWithMethod = myEffect.pipe(Effect.map(transformation))
Example (Adding a service charge)
import { Effect, pipe } from "effect"
const addServiceCharge = (amount: number) => amount + 1
const fetchTransactionAmount = Effect.promise(() => Promise.resolve(100))
const finalAmount = pipe(
fetchTransactionAmount,
Effect.map(addServiceCharge)
)
Effect.runPromise(finalAmount).then(console.log)
// Output: 101
