hexagon / cryptalk

HTML5/Node.js based, client side (E2EE) encrypted instant chat

Hi, I'm Hexagon!

A selection of my work:

• My blog at hexagon.56k.guru, where i write about JavaScript, my librares and contributions and more.

• Croner - JavaScript cron parser/scheduler. ESM. Node, Deno, Bun, Browser. No dependencies.

• Croner-rust - Rust cron parser/scheduler. Fully featured, performant and minimalistic.

• Pup - Fully featured process manager, written in typescript with love for Deno.

• Lumocs - Easy to use static site generator for documentation, utilizing Lume and Deno.

• Base64 - Base64 and Base64url to string or arraybuffer. ESM. Node, Deno, Bun, Browser. No dependencies.

• Minitz - Minimal timezone conversion library for JavaScript, written for Croner, but now it's own package. No dependencies.

• Entsoe-api-client - Unofficial ENTSO-e REST API Client for Deno and Node.

• Bundlee - Static file bundler for web frameworks supported by Deno (and usable on cli).

• Proper-tags - Modernised (pure ESM) version of the popular package common-tags.

• DETRIS - Server side, web based multiplayer Tetris-like game written in Deno using Deno KV as persistent storage.

• (etc...)

Other than working on my own projects, I often find myself converting existing packages from CommonJS to Deno/Node/Bun ESM.

cryptalk's Issues

Change Colours?

Hello!
I'm wondering if it's possible to change like the colours for the time stamps and messages and help banner. Like which file would it be and how would I go about doing that?

Thanks,

Network breaking

Me and a friend of mine both tried to run this in our own servers. And both times it broke our internet. And it broke so bad on my friend's side that he had to do a factory reset on his router to get anything to work.

Something is causing things to break.

Heroku Installation Does Not Work

clean;git clone https://github.com/Hexagon/cryptalk.git;cd cryptalk;heroku create;git add .;git push heroku master;heroku restart;heroku open;heroku logs -t;

The above does not work when pushing Cryptalk to Heroku.

clean;git clone https://github.com/Hexagon/cryptalk.git;cd cryptalk;npm install;node server.js;open http://localhost:8080;

Works but wont allow any kind of chatting or joining channels. Seems like it's broken.

mediator not defined in client.js

Steps: enter a too long nick

client.js:68 Uncaught TypeError: mediator is not a function

castrato is "bundled" in client/source/vendor

When available at npm, switch to normal dev dependency include

HTTPS support?

I think it'd be really nice to have HTTPS support for cryptalk.

README.md says npn run start, should be npm run start

In README.md please fix to

Start server
npm run start

Error in the container created by docker command

Good morning,

When I type docker run -d --restart=always -p 6666:8080 hexagon/cryptalk, the container crashes.

I get the following logs in the container:

cp: can't create directory '/usr/src/app/external-public/css': No such file or directory
cp: can't create directory '/usr/src/app/external-public/gfx': No such file or directory
cp: can't create '/usr/src/app/external-public/index.html': No such file or directory
cp: can't create directory '/usr/src/app/external-public/js': No such file or directory

[Request] Migrate to socket.io 3.0.0

@Hexagon See https://socket.io/docs/migrating-from-2-x-to-3-0/ for details.

Dockerhub image broken

Hi, the latest Dockerhub image isnt properly compiled and just spits out errors. While Ive just put it on my own registry, its most likely helpful if you rebuild it.

Thanks.

Undefined room after reconnecting to server

Steps to reproduce (using latest docker image as of writing):

• Join a room
• Server disconnects and reconnects for whatever reason (i.e. internet outage)
• Type /leave
• Will show Left room undefined

Image and file transfer support?

I think it would be more perfect if it could

> and < in room name

If having > or < in the room name, socket io fails in some way. It seems lite the generated json becomes invalid and the socket gets garbled. If I html-escape the room name before joining the channel, all is fine. But i want to join Error> , not Error> :)

Example:
http://www.host.com/#Error>:MyLongKey

Generates:
Uncaught TypeError: Cannot read property 'emit' of undefined

At:
cryptalk.js L372
room
? post('error', templates.messages.already_in_room)
: socket.emit('room:join', payload)
