October 3, 2022 — JavaScript API built-in module and request body updates

We've made updates to the EdgeWorkers JavaScript API built-in modules and expanded support for ReadableStreams in the contents of the request body.

• You can now reference public keys locally within your EdgeWorkers code bundle and pass them into the crypto built-in module. Crypto libraries, such as crypto-es, no longer need to be packed locally into the EdgeWorkers code bundle.

• The encoding built-in module now supports atob(), and btoa() in your EdgeWorkers code bundles to handle text in various character encodings, including legacy non-UTF-8.

• The Request Object now supports a body property. This read-only ReadableStream value is used to read the contents of the request body. It is only available when using the responseProvider event.

• The body property of the httpRequest() function now supports ReadableStreams in the contents of the request body.
