Installation

npm i @gesslar/toolkit

Usage

Toolkit is environment aware and automatically detects whether it is being used in a web browser or in Node.js. You can optionally specify the node or browser variant explicitly.

Browser-like

TypeScript editors do not pick up types from jsDelivr. If you want inline types without installing from npm, use the esm.sh ?dts URL or install the package locally for development and use the CDN at runtime.

jsDelivr (runtime only)

https://cdn.jsdelivr.net/npm/@gesslar/toolkit

esm.sh (runtime, types)

https://esm.sh/@gesslar/toolkit
https://esm.sh/@gesslar/toolkit?dts` (serves `.d.ts` for editors)

Node.js

import * as TK from "@gesslar/toolkit"

import {Data, FileObject, Cache} from "@gesslar/toolkit"

import {Data, FileObject} from "@gesslar/toolkit/node"

import { Data, Collection, Util } from '@gesslar/toolkit/browser'

The browser version includes: Collection, Data, Disposer, HTML, Notify, Sass, Tantrum, Type (TypeSpec), Util, and Valid. Node-only modules (Cache, CappedDirectoryObject, Contract, DirectoryObject, FileObject, FS, Glog, Schemer, TempDirectoryObject, Term, Terms) are not available in the browser version.
