= Terminus

Terminus is a {ruby_link}/{hanami_link} web server that allows you to manage {trmnl_link} devices running on your own local network or hosted cloud. This is our flagship BYOS implementation that aims to be compatible with our {trmnl_link} Core server but _also different_ since this open source solution provides features not possible in our Core application.

image:https://render.com/images/deploy-to-render-button.svg[Deploy to Render,link=https://render.com/deploy]

⚠️ This is a Beta software as we haven't reached 1.0.0 status as of yet. This means -- while we strive to reduce the number of changes that require effort on your part to a minimum -- there will be times when changes can't be avoided.

== Features

* Provides privacy first functionality by empowering you to run your own private server, network, and devices. You own the stack and the data. 🎉
* Built atop {ruby_link} and {hanami_link}.
* Uses {esbuild_link} for asset management.
* Uses {htmx_link} for Hypermedia-Driven user interfaces.
* Uses {imagemagick_link} for image processing.
* Uses {overmind_link} for running multiple processes.
* Uses {postgres_link} for the database.
* Uses {puma_link} for the server.
* Uses {rodauth_link} for authentication.
* Uses {sidekiq_link} for worker jobs.
* Uses {valkey_link} for the key/value cache.
* Supports {yjit_link}.
* Supports {docker_link}.
* Supports {trmnl_link} devices.

The following is a high level overview you can use to compare/contrast when deciding between using this Build Your Own Server (BYOS) implementation or our link:https://trmnl.com[hosted] solution.

*Legend*

* ⚪️ Planned.
* 🟢 Supported.
* 🟡 Partially supported.
* 🔴 Not supported, not implemented, or isn't applicable.

*Matrix*

The following documents the features supported in this implementation which are similar to our {trmnl_link} Core server. While we aim to be compatible with Core, the experience will be slightly different in look, feel, and behavior.

== Requirements

* {git_link}.
* {ruby_link}.
* {hanami_link}.
* {node_link}.
* {postgres_link}.
* {valkey_link}: Can be swapped out for {redis_link} or {dragonfly_link} if desired.
* {hadolint_link} (optional, for development): For `Dockerfile` linting.
* {chrome_link} (optional, for development): For screen generation via the headless browser.
* {overmind_link} (optional, for development): Uses your `Procfile` to launch processes.
* {docker_link} (optional when only using Ruby).
* {trmnl_link} device (optional, you can use virtual devices).

== Quick Start

To immediately spin up Terminus on your local machine using {docker_link}, run:

[source,bash]
----
curl https://raw.githubusercontent.com/usetrmnl/terminus/refs/heads/main/scripts/docker/quick.sh | bash
----

Once launched, open `http://localhost:2300` in your browser then click the _Register_ link to register and log into the system.

⚠️ This script is not idempotent which means you can't run it more than once since your database credentials will be different each time. This is only meant for getting up and running quickly to explore the feature set, not permanent use. For permanent use, see the link:https://github.com/usetrmnl/terminus/blob/main/doc/docker.adoc[Docker] documentation.

== Setup

To set up this project for local development, run:

[source,bash]
----
git clone https://github.com/usetrmnl/terminus
cd terminus
bin/setup
----

💡 The setup script is idempotent so you can run it multiple times without harm. To rebuild a file managed by the setup script, delete the desired file and rerun setup to recreate.

== Upgrade

To upgrade this project for local development, run:

[source,bash]
----
cd terminus
bin/upgrade
----

Watch for any changes that need to be addressed in the output. Otherwise, if no changes are detected, you are set.

== Usage

To launch the server, run:

[source,bash]
----
# Development
overmind start --port-step 10 --procfile Procfile.dev --can-die assets,migrate

# Production
overmind start --port-step 10 --can-die assets,migrate
----

To view the app, use either of the following:

* *Secure*: https://localhost:2443
* *Insecure*: http://localhost:2300

From your browser, you can then click on the _Register_ link to register and log into the system.

=== Configuration

See {doc_configuration_link} documentation for details.

=== Users

When launching this application for the first time, there will be no users. The first user to register will automatically be given _Verified_ status along with full access to the system. All subsequent users will marked as _Unverified_ and must be manually _Verified_ in order to have access to the system. In the future, more fine grained control will be provided for individual users, roles, and permissions.

Also, once logged in, you can manage your settings as follows:

* Visit `/me/login` to update your email address.
* Visit `/me/password` to update your password.
* Visit `/me/remember` to enable, disable, or forget if you should be remembered.

=== Devices

See {devices_link} documentation for details.

=== Firmware

In accordance with the {unbrickable_pledge_link}, the latest version of Terminus always supports the latest version of our {firmware_link}. If you are running on older firmware, you'll need to use an older version of Terminus. Here's a rough breakdown of the Firmware version history where changes were applied that might cause issues if you haven't upgraded your devices in a while:

* *Firmware 1.6.9* (and lower): Supported by Terminus link:https://github.com/usetrmnl/terminus/releases/tag/0.41.0[0.41.0] and lower.
* *Firmware 1.6.10* (and higher): Supported by Terminus link:https://github.com/usetrmnl/terminus/releases/tag/0.42.0[0.42.0] and higher.
