Todo Back is a deliberately small Rails JSON API packaged as a native StartOS 0.4 service. Its purpose is to validate the complete local-build → .s9pk → sideload workflow before investing in a larger application.

The interface root also serves a dependency-free browser page for quickly exercising every todo operation.

API

GET /up — Rails and PostgreSQL health check
GET /todos — list todos
GET /todos/:id — fetch one todo
POST /todos — create with { "todo": { "title": "...", "completed": false } }
PATCH /todos/:id — update title and/or completion state
DELETE /todos/:id — delete a todo

Architecture

The package builds the Rails application from the root Dockerfile and runs PostgreSQL 17 as a second StartOS subcontainer. PostgreSQL data, Rails local storage, and generated secrets are persisted in separate StartOS volumes. On every start, PostgreSQL becomes healthy, bin/rails db:prepare runs, and then Puma starts on port 3000. StartOS publishes that port as an API interface and terminates TLS.

SECRET_KEY_BASE and the database password are generated during installation and stored in the backed-up config volume. Backups use the SDK PostgreSQL dump integration and also include config and local storage.

Development

Install application dependencies and run tests:

bundle install
bin/rails db:prepare
bin/rails test

Build the x86_64 sideload package from inside a StartOS packaging workspace:

npm install
make x86

The resulting todo-back_x86_64.s9pk can be uploaded from StartOS under System → Sideload Service.

Gitea Actions builds an artifact for each push to main. A matching StartOS extended-SemVer tag, such as v0.2.0_0 for package version 0.2.0:0, additionally installs the package through the configured Gitea runner. See .ai-workspace/UPDATING.md for the release policy and runner requirements.

Status

This is an unauthenticated MVP intended for sideload testing on a trusted network. Add authentication before exposing its interface beyond trusted gateways.
