Update

• See changelog

Found a bug ?

• Tell it in my github issues dont be afraid :)

Installation

npm i pipipe

Import

const createPipeline = require("pipipe");
// OR
import createPipeline from "pipipe";

Or in the browser

<script src="https://unpkg.com/pipipe@1.0.0/dist/index.js"></script>

How to use ?

Simple example

const reverseStrPipeline = createPipe()
  .pipe((str: string) => str.split(""))
  .pipe((arr: string[]) => arr.reverse())
  .pipe((arr: string[]) => arr.join(""));

const result = reverseStrPipeline.execute("hello world");

console.log(result); //dlrow olleh

Copy

Copy a pipeline to create a new one from it

const lowerCasePipeline = createPipe().pipe((str: string) => str.toLowerCase());
const splitPipepline = lowerCasePipeline
  .copy()
  .pipe((str: string) => str.split(""));

console.log(
  splitPipepline.execute("HI"), // "hi"
  lowerCasePipeline.execute("HI") // ["h", "i"]
);

Async

Execute asynchronously the pipeline

type UserList = { id: string; name: string; token: string }[];

const getUserTokenPipeline = createPipe()
  .pipe(async (id: string) => {
    const req = await fetch(`/userById/${id}`);
    return await req.json();
  })
  .pipe((result: UserList) => result[0]?.token)
  .catch(handleErr);

const token = await getUserTokenPipeline.executeAsync("123456789");

pipeInsert

Insert a new pipe to a specific position

const reverseStrPipeline = createPipe()
  .pipe((str: string) => str.split(""))
  .pipe((arr: string[]) => arr.join(""))
  .pipeInsert((arr: string[]) => arr.reverse(), 1);

const result = reverseStrPipeline.execute("hello world");

console.log(result); //dlrow olleh

pop, shift, splice

Same as the pop, shift, splice array method to remove pipe(s) from the pipeline
