Vibecode Bubble

You are building a lean indie version of Bubble.

Create the following project files first, then implement the application by following them. Keep the files updated as decisions change. Do not collapse this into a single README or prompt.

===== README.md =====
# Bubble indie build

## Goal

Build the smallest trustworthy replacement for the core Bubble workflow for one developer or a tiny team.

## Scope

Rebuild the target app directly in code with CRUD, auth, workflows, and hosting rather than cloning Bubble as a platform.

## Quick start

1. Install the documented dependencies.
2. Copy `.env.example` to `.env`.
3. Run the development command chosen during implementation.
4. Complete the acceptance checks in `BUILD_PLAN.md`.

## Honest limits

This build deliberately does not replace:
- visual editor
- workflow builder
- plugin marketplace
- hosting/scaling
- nondeveloper maintenance
- templates

If those capabilities are essential, use Appsmith instead of pretending the gap is solved.

===== AGENTS.md =====
# Agent instructions

- Optimize for a working, understandable weekend build.
- Prefer the fewest moving parts that satisfy the brief.
- Do not invent cryptography, security guarantees, APIs, or compliance claims.
- Keep secrets out of source control and logs.
- Add focused tests for destructive, security-sensitive, and data-loss paths.
- Run the project checks before declaring the build complete.
- Record any deliberate shortcut in the README under "Tradeoffs".

===== BUILD_PLAN.md =====
# Build plan

## Original build brief

Build me the app I currently run on Bubble, as plain code I own. Requirements:

- First ask me for: the 3-5 core screens, the data types with their fields,
  and the single workflow that matters most. Rebuild that app, not Bubble.
- Stack: Node + Express + better-sqlite3, server-rendered EJS templates plus
  htmx for interactivity. No SPA framework, no build step.
- CRUD for each data type: list page with search and filters, detail page,
  create and edit forms with validation.
- Workflows become plain functions: a form submit updates rows, sends email
  via Resend (key in .env), redirects. Scheduled workflows become node-cron
  jobs in the same process.
- Auth only if people other than me log in: email+password sessions with
  bcrypt and a session cookie, no roles unless I named them. If it is just
  me, skip auth and bind to localhost.
- File uploads go to uploads/, images resized with sharp.
- One SQLite file plus a nightly CSV dump of every table, data never trapped.
- Out of scope: a visual editor, a plugin system, anything platform-shaped.
  The deliverable is one app that deploys with node server.js on a $5 VPS.
- README: deploy steps and how to add a field later, the code is the editor
  now.

## Required capabilities

- web framework
- database
- auth
- hosting
- payment/email APIs
- product-specific integrations

## Delivery order

1. Scaffold the smallest runnable application and document its commands.
2. Implement the primary data model and core workflow.
3. Add validation, safe failure states, and persistence.
4. Cover the critical path with automated tests.
5. Exercise a clean install from the README and fix every missing step.

## Done when

- A new user can go from clone to first successful workflow using only the README.
- The core workflow works without paid infrastructure unless the brief requires it.
- Tests cover the highest-risk behavior.
- Known limitations are explicit rather than hidden.

# Copy to .env and document every variable when it is introduced.
# Never put real credentials in this file.

APP_ENV=development
# Add only values required by the selected implementation.

You are building a production product version of Bubble.

Create the following project files first, then implement the application by following them. Keep the files updated as decisions change. Do not collapse this into a single README or prompt.

===== PRODUCT.md =====
# Bubble product brief

## Problem

A specific Bubble app is often vibecodable now; rebuilding Bubble's editor, workflow engine, plugin ecosystem, hosting, and scaling layer is not.

## Product outcome

Rebuild the target app directly in code with CRUD, auth, workflows, and hosting rather than cloning Bubble as a platform.

## Target user

A serious builder who needs a maintainable product foundation rather than a one-off demo.

## Required capabilities

- web framework
- database
- auth
- hosting
- payment/email APIs
- product-specific integrations

## Explicit non-goals for v1

- visual editor
- workflow builder
- plugin marketplace
- hosting/scaling
- nondeveloper maintenance
- templates

## Success criteria

- The primary workflow is measurable end to end.
- Setup is reproducible in a clean environment.
- Failure, recovery, and support paths are documented.
- Product claims match what the implementation actually guarantees.

- First ask me for: the 3-5 core screens, the data types with their fields,
  and the single workflow that matters most. Rebuild that app, not Bubble.

- README: deploy steps and how to add a field later, the code is the editor
  now.

## Boundaries

Separate the product into replaceable modules for interface, application logic, persistence, external integrations, and operational concerns. Keep domain logic independent from delivery frameworks and vendors.

## Production baseline

- Configuration: validated at startup with safe local defaults where possible.
- Security: least privilege, input validation, secret redaction, rate limits on abuse-prone paths, and no invented security primitives.
- Data: explicit schema and migrations, transactional writes where integrity matters, backup and restore instructions.
- Integrations: adapters around third-party providers, idempotent webhook or job processing, bounded retries, and timeouts.
- Observability: structured logs with request or operation IDs, an error-tracking hook, and health/readiness checks where a server exists.
- Quality: unit tests for domain rules, integration tests at module boundaries, and one end-to-end critical-path test.

## Decision records

For each major dependency, document why it was chosen, its failure mode, and how it can be replaced. Do not introduce infrastructure until a requirement justifies it.

===== AGENTS.md =====
# Agent instructions

- Read `PRODUCT.md` and `ARCHITECTURE.md` before changing code.
- Implement milestone by milestone; keep each change reviewable and leave the application runnable.
- Treat authentication, payments, encryption, imports, webhooks, and destructive actions as high-risk boundaries when present.
- Never invent cryptography or silently weaken a requirement to make a test pass.
- Use provider interfaces for external services and deterministic fakes in tests.
- Add migrations and rollback or recovery notes for persistent data changes.
- Log useful operational context without credentials, tokens, passwords, or personal data.
- Update documentation and run all checks before completing a milestone.

===== MILESTONES.md =====
# Delivery milestones

## M0 — Decisions and scaffold

- Confirm the runtime, persistence model, threat boundaries, and deployment target.
- Create a reproducible local environment and continuous checks.

## M1 — Core workflow

- Implement the smallest end-to-end product path with validation and tests.
- Keep integrations behind interfaces.

## M2 — Trust layer

- Add secure failure behavior, recovery paths, audit-relevant events, and data safeguards.
- Test abuse cases and destructive operations.

## M3 — Operability

- Add structured logs, error reporting hooks, health signals, backup/restore documentation, and deployment configuration.

## M4 — Release gate

- Run a clean-install test, critical-path end-to-end test, dependency review, and documented rollback exercise.
- Compare the shipped behavior with `PRODUCT.md` and publish remaining limitations.

===== OPERATIONS.md =====
# Operations

## Before release

- Validate configuration and secrets at startup.
- Define backup, restore, and rollback procedures and test them.
- Document logs, error tracking, health signals, and alert ownership.
- Set dependency update and vulnerability review expectations.

## Incident checklist

1. Contain the issue without destroying evidence or user data.
2. Record the timeline and affected scope.
3. Rotate exposed secrets and revoke compromised sessions or credentials.
4. Restore from a verified source when needed.
5. Document the root cause, remediation, and regression test.

## Launch constraint

Do not market omitted Bubble capabilities as implemented. The v1 non-goals in `PRODUCT.md` remain user-visible limitations until they are deliberately delivered.
