@leight/utils

This package contains a lot of small utilities from various other packages, which could be safely used on client/server.

Installation

npm i @leight/utils

API

Each section here is exported from the package.

chain()

Useful when you need to rotate through values, for example true -> false -> undefined.

Initial use case for this method was rotating sort order in tables ("asc" -> "desc": -> undefined).

import {chain} from "@leight/utils";
 
/**
 * Next value: `false`
 */
console.log("Next value", chain(true, [true, false, undefined]));
/**
 * Next value: `A`
 */
console.log("Next value", chain("C", ["A", "B", "C"]));

cleanOf()

Takes an object as an input and removed all undefined properties while preserving nulls.

Second parameter of the method is options object (opens in a new tab) from fast-clean.

import {cleanOf} from "@leight/utils";
 
/**
 * Only `wipeMe` will be removed.
 */
console.log("cleanOf", cleanOf({
    foo: "true",
    bar: false,
    hello: null,
    wipeMe: undefined,
}));
