Uploaded files come from this origin, so one served with a JavaScript
type could run as one of the app's own scripts. Browsers accept sixteen
spellings of that type, and Disk URLs sign the type they were minted
with, so refusing a list of types at upload can't cover links already
out there. Instead, a middleware rewrites the type of anything Active
Storage reads out that isn't plainly media, a PDF or plain text to
application/octet-stream, whatever the URL says.

Campfire
Campfire is a web-based chat application. It supports many of the features you'd expect, including:
- Multiple rooms, with access controls
- Direct messages
- File attachments with previews
- Search
- Notifications (via Web Push)
- @mentions
- API, with support for bot integrations
Running your own Campfire instance
Campfire's Docker image contains everything needed for a fully-functional,
single-machine deployment. This includes the web app, background jobs, caching,
file serving, and SSL. You can use our pre-built image at
ghcr.io/basecamp/once-campfire:latest, or build your own from this repo.
Deploying with ONCE
The easiest way to self-host Campfire is with ONCE. It will guide you through the initial set up and then keep your instance up to date automatically.
If you don't already have once installed, run this on the machine you want to run Campfire on:
curl https://get.once.com | sh
once will launch as soon as the install is finished.
Choose Campfire from the list of applications, follow the instructions, and ONCE will take care of the rest.
If you prefer the command line to the dashboard, you can deploy directly:
once deploy ghcr.io/basecamp/once-campfire --host chat.example.com
Deploying with Docker
If you'd rather run the Docker image yourself, you can read more about that in the self-hosting guide.
Tip
When you start Campfire for the first time, you'll be guided through a wizard to create an admin account. The email address that you enter for the admin account will be visible on the sign-in page, it's there so that people have someone to contact if they need help with their account. If that bothers you, put in any email address you want and create yourself a new admin account.
