A set of utilities to help identify IPFS resources

Package Exports

  • is-ipfs

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (is-ipfs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

is-ipfs

build status dignified.js

A set of utilities to help identify IPFS resources.

Install

In Node.js through npm

$ npm install --save is-ipfs

Browser: Browserify, Webpack, other bundlers

The code published to npm that gets loaded on require is in fact an ES5 transpiled version with the right shims added. This means that you can require it and use with your favorite bundler without having to adjust asset management process.

var is-ipfs = require('is-ipfs')

In the Browser through <script> tag

Loading this module through a script tag will make the IsIpfs obj available in the global namespace.

<script src="https://unpkg.com/is-ipfs/dist/index.min.js"></script>
<!-- OR -->
<script src="https://unpkg.com/is-ipfs/dist/index.js"></script>
