one-webcrypto

The WebCrypto API is available in most browsers, under a global variable:

``js
// in web pages
const webcrypto = window.crypto
// in web workers, etc.
const webcrypto = self.crypto
// or generally under
const webcrypto = globalThis.crypto
`

It is also available in NodeJS since version 15.

However, it is accessed differently:

`js
// in node with commonjs
const webcrypto = require("crypto").webcrypto
// in node with ES Modules
import crypto from "crypto"
const webcrypto = crypto.webcrypto
`

These different ways of getting access to valuable cryptographic primitives (see webcrypto.subtle) accross platforms (node & browsers) are hard to get right.

fork

This is functionally equivalent to fission/one-webcrypto

install

`sh
npm i -S @bicycle-codes/one-webcrypto
`

Usage

With this package, you can just import the WebCrypto API like so:

`js
import { webcrypto } from "@bicycle-codes/one-webcrypto"

webcrypto.getRandomValues( //...
await webcrypto.subtle.generateKey( //...
`

Or with CommonJS:

`js
const { webcrypto } = require("@bicycle-codes/one-webcrypto")
`

Compatibility Issues

This package uses a fairly new package.json standard field, the exports` field.

Read more about it:
* "export maps" in nodejs documentation.
* "package exports" in webpack documentation
* original "pkg exports" proposal

We're also making use of webpack's pseudo-standard of the "browser" flag for imports.

So if your environment doesn't support that, it _may_ or _may not_ work.

We know that this setup works (should work) with
* NodeJS 15+ (thus also e.g. mocha)
* ESBuild
* Webpack 5
* Vite
* SvelteKit
* Snowpack
* Parcel 2

We know that this setup can have issues with
* Create React App

If you have any experience (whether it supports the claims above or not), please create an issue.
The idea is to help each other out in these crazy bundler times and document what works and what doesn't. :)
