Resolver Pipe

This is a functional pipe that makes it easier and cleaner to write complex resolvers in TypeScript. A pipe automatically pipes the output of one function into the next function.

Including a wrapper for easy input validation with zod.

Installation

To install resolver-pipe:

npm install @markhaehnel/resolver-pipe

Usage

import resolver from "@markhaehnel/resolver-pipe";

const myPipe = resolver.pipe(
  (a: number, b: number) => a + b,
  (id: number) => `/article/${id}`
);

await myPipe(1, 3); // => "/article/4"

With validation

import resolver from "@markhaehnel/resolver-pipe";
import { z } from "zod";

const SearchProductParams = z.object({
  query: z.string().min(2),
  maxPrice: z.number().positive(),
  limit: z.number().int().optional(),
});

const searchProductPipe = resolver.pipe(
  resolver.zod(SearchProductParams),
  normalizeQuery,
  makeSearchRequest,
  filterProducts
);

// throws if validation fails
await searchProductPipe({ query: "usb charger", maxPrice: 16.5 });
