Confignation

config.yml

app:
  port: 3000

db:
  type: mongodb # sqlite or mongodb or firebase

If you use mongodb, you need to specify the environment variable DB_URL

# eg:
export DB_URL=mongodb+srv://account:passwd@***.***.***.mongodb.net/db_count

repl.it can use .env file, documentation

DB_URL="mongodb+srv://account:passwd@***.***.***.mongodb.net/db_count"

How to use

The chat room URL looks like this:

https://chat.error.work/room/@:name?title=the title whatever

Just use your own name and title, eg:

https://chat.error.work/room/@test?title=a simple title

And you can open in new tab or use iframe, example

SVG Charts

By the feature of SVG <foreignObject>, we can make an SVG element contain a standard HTML page.

As we know SVG can be referenced as an image.

And then...

Magical! a Real-time chart that can be inserted into any document that supports images.

Just like this guy's personal home page

This is all parameters, do it yourself:

https://chat.error.work/room/@test/svg?width=750&height=360&limit=20&theme=light&fontSize=13&title=TwoThreeWang@github.com: ~
