README

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:

sh
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:

sh
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.

Authenticated room, message, sidebar and search pages use a bounded 64 MiB cache per worker.
Set CAMPFIRE_RESPONSE_CACHE_MB=0 to disable it. Every request still checks authentication
and room access; commits from any SQLite writer invalidate complete cached HTML and gzip bodies.
Native HTML, JSON and stream fragments have a separate 64 MiB memory limit per worker;
shared rate limits retain their existing store.
