How-to: a todo manager

A working todo backend in one poops.json — table, REST API, filtering, and a form. No code.

The backend half. You end with an API and a form partial. The page that lists and toggles todos, served on the same origin as the API, is laxative's version of this how-to.

1. Define the resource

{
  "septic": {
    "db": "data/todos.db",
    "resources": {
      "todos": {
        "methods": ["GET", "POST", "PUT", "DELETE"],
        "access": { "read": "public", "write": "public" },
        "fields": {
          "title":   "string required",
          "done":    "boolean = false",
          "created": "datetime = now",
          "updated": "datetime = now!"
        }
      }
    }
  }
}

write: "public" keeps the demo auth-free. For a real app use a role and log in via POST /api/_auth/login.

= now stamps created once; = now! re-stamps updated on every change.

2. Serve it

npx septic serve      # http://localhost:3000

3. Use the API

# add
curl -X POST localhost:3000/api/todos \
  -H 'content-type: application/json' -d '{"title":"buy milk"}'
# → { "id": 1, "title": "buy milk", "done": false, "created": "...", "updated": "..." }

# list the open ones — stored as 0/1, so the filter takes 0; the response says false
curl 'localhost:3000/api/todos?done=0&sort=created&order=desc'

# mark done — updated re-stamps automatically
curl -X PUT localhost:3000/api/todos/1 \
  -H 'content-type: application/json' -d '{"done":true}'

# delete
curl -X DELETE localhost:3000/api/todos/1

Filtering, sorting and pagination come for free: ?done=0, ?sort=created&order=desc, ?limit=&offset=.

4. Add a form

Generate an HTML form for adding todos, wired to /api/todos:

"build": {
  "forms": {
    "todos": {
      "into": "src/markup/_partials",
      "submitLabel": "Add",
      "hints": { "title": { "label": "What needs doing?" } }
    }
  }
}

npx septic build writes src/markup/_partials/todos-form.html — a real <form> with a title input and a done checkbox (created/updated are omitted, they're server-owned). It POSTs to /api/todos and works with HTMX or plain HTML. Include it in a poops page and you have an add-todo form on a static site, backed by the API.

What you got

One resource definition → a todos table, five REST routes, validation, filtering, and a form — the whole backend of a todo app. To turn it into a full app (a page that lists and toggles todos), see the same how-to in laxative.
