Deno Native Messaging Host

Installation and usage on Chrome and Chromium

1. Navigate to chrome://extensions.
2. Toggle Developer mode.
3. Click Load unpacked.
4. Select native-messaging-deno folder.
5. Note the generated extension ID.
6. Open nm_deno.json in a text editor, set "path" to absolute path of nm_deno.js and chrome-extension://<ID>/ using ID from 5 in "allowed_origins" array.

8. Make sure deno executable and nm_deno.js are executable. To download deno executable into the cloned GitHub directory that is used as the local unpacked extension directory (and optionally strip symbolic information from the deno executable to reduce size) you can run

    wget --show-progress \
    --progress=bar \
    --output-document deno.zip \
    https://github.com/denoland/deno/releases/latest/download/deno-x86_64-unknown-linux-gnu.zip \
    && unzip deno.zip \
    && rm deno.zip \
    && strip deno 

9. To test click service worker link in panel of unpacked extension which is DevTools for background.js in MV3 ServiceWorker, observe echo'ed message Deno Native Messaging host. To disconnect run port.disconnect().

The Native Messaging host echoes back the message passed.
