r.pipe

HttpEffect route builder based on IxMonad

Importing

import { r } from '@marblejs/core';

+ pipe

r namespace function. Creates pipeable RouteEffect builder.

Type declaration

pipe :: ...Arity<IxBuilder, IxBuilder> -> RouteEffect

r.pipe builder pays attention to the order of applied operators.

const example$ = r.pipe(
r.matchPath('/'),
r.matchType('GET'),
r.use(middleware_1$),
r.useEffect(req$ => req$.pipe(
// ...
)),
r.use(middleware_2$), // ❌ type error!
);
// or
const example$ = r.pipe(
r.matchType('GET'),
r.matchPath('/'), // ❌ type error!
r.use(middleware_1$),
r.use(middleware_2$),
r.useEffect(req$ => req$.pipe(
// ...
)),
);

Correct order:

  1. matchPath

  2. matchType

  3. use ...

  4. useEffect

  5. applyMeta ...
