# betterNAS Skeleton
This is the root build skeleton for the monorepo.
Its job is simple:
- lock the repo shape
- lock the language per runtime
- lock the first shared contract surface
- give agents a safe place to work in parallel
- keep the list of upstream references we are stealing from
## Repo shape
```text
betterNAS/
├── apps/
│ ├── web/ # Next.js control-plane UI
│ ├── control-plane/ # Go control-plane API
│ ├── node-agent/ # Go NAS runtime + WebDAV surface
│ └── nextcloud-app/ # optional Nextcloud adapter
├── packages/

## Runtime and language choices
| Part | Language | Why |
| -------------------- | ---------------------------------- | -------------------------------------------------------------------- |
| `apps/web` | TypeScript + Next.js | best UI velocity, best admin/control-plane UX |
| `apps/control-plane` | Go | strong concurrency, static binaries, operationally simple |
| `apps/node-agent` | Go | best fit for host runtime, WebDAV service, and future Nix deployment |
| `apps/nextcloud-app` | PHP | native language for the Nextcloud adapter surface |
| `packages/contracts` | OpenAPI + JSON Schema + TypeScript | language-neutral source of truth with practical TS ergonomics |
## Canonical contract rule
The source of truth for shared interfaces is:
1. [`docs/architecture.md`](./docs/architecture.md)
2. [`packages/contracts/openapi/betternas.v1.yaml`](./packages/contracts/openapi/betternas.v1.yaml)
3. [`packages/contracts/schemas`](./packages/contracts/schemas)
4. [`packages/contracts/src`](./packages/contracts/src)
Agents must not invent private shared request or response shapes outside those
locations.
## Parallel lanes
```text
shared write surface
+-------------------------------------------+
| docs/architecture.md |
| packages/contracts/ |
+----------------+--------------------------+
|
+-----------------+-----------------+-----------------+
| | | |
v v v v
NAS node control plane local device cloud layer
lane lane lane lane
```
Allowed ownership:
- NAS node lane
- `apps/node-agent`
- future `infra/nix/node-*`
- control-plane lane
- `apps/control-plane`
- DB and queue integration code later
- local-device lane
- mount docs first
- future helper app
- cloud layer lane
- `apps/nextcloud-app`
- Nextcloud mapping logic
- shared contract lane
- `packages/contracts`
- `docs/architecture.md`
## The first verification loop
```text
[node-agent]
serves WebDAV export
|
v
[control-plane]
registers node + export
issues mount profile
|
v
[local device]
mounts WebDAV in Finder
|
v
[cloud layer]
optionally exposes same export in Nextcloud
```
If a task does not make one of those steps more real, it is probably too early.
## Upstream references to steal from
### Monorepo and web
- Turborepo `create-turbo`
- https://turborepo.dev/repo/docs/reference/create-turbo
- why: monorepo base scaffold
- Turborepo structuring guide
- https://turborepo.dev/repo/docs/crafting-your-repository/structuring-a-repository
- why: package boundaries and task graph rules
- Next.js backend-for-frontend guide
- https://nextjs.org/docs/app/guides/backend-for-frontend
- why: keep Next.js as UI/BFF, not the system-of-record backend
### Go control plane
- Go routing enhancements
- https://go.dev/blog/routing-enhancements
- why: stdlib-first routing baseline
- `chi`
- https://github.com/go-chi/chi
- why: minimal router if stdlib patterns become too bare
- `pgx`
- https://github.com/jackc/pgx
- why: Postgres-first Go driver
- `sqlc`
- https://github.com/sqlc-dev/sqlc
- why: typed query generation
- `go-redis`
- https://github.com/redis/go-redis
- why: primary Redis client
- `asynq`
- https://github.com/hibiken/asynq
- why: practical Redis-backed job system
- `koanf`
- https://github.com/knadh/koanf
- why: layered config if env-only config becomes too small
- `envconfig`
- https://github.com/kelseyhightower/envconfig
- why: tiny env-only config option
- `log/slog`
- https://pkg.go.dev/log/slog
- why: structured logging without adding a logging framework first
- `oapi-codegen`
- https://github.com/oapi-codegen/oapi-codegen
- why: generate Go and TS surfaces from OpenAPI
### NAS node and WebDAV
- Go WebDAV package
- https://pkg.go.dev/golang.org/x/net/webdav
- why: embeddable WebDAV server implementation
- `hacdias/webdav`
- https://github.com/hacdias/webdav
- why: small standalone WebDAV reference
- NixOS manual
- https://nixos.org/manual/nixos/stable/
- why: declarative host setup and service wiring
- Nixpkgs
- https://github.com/NixOS/nixpkgs
- why: service module and packaging reference
### Local device and mount UX
- Finder `Connect to Server`
- https://support.apple.com/en-lamr/guide/mac-help/mchlp3015/mac
- why: native mount UX baseline
- Finder WebDAV mounting
- https://support.apple.com/is-is/guide/mac-help/mchlp1546/mac
- why: exact v1 mount path
- Keychain data protection
- https://support.apple.com/guide/security/keychain-data-protection-secb0694df1a/web
- why: local credential storage model
- Finder Sync extensions
- https://developer.apple.com/library/archive/documentation/General/Conceptual/ExtensibilityPG/Finder.html
- why: future helper app / Finder integration reference
- WebDAV RFC 4918
- https://www.rfc-editor.org/rfc/rfc4918
- why: protocol semantics and edge cases
### Cloud and adapter layer
- Nextcloud app template
- https://github.com/nextcloud/app_template
- why: thin adapter app reference
- AppAPI / External Apps
- https://docs.nextcloud.com/server/latest/admin_manual/exapps_management/AppAPIAndExternalApps.html
- why: official external-app integration path
- Nextcloud WebDAV docs
- https://docs.nextcloud.com/server/latest/user_manual/en/files/access_webdav.html
- why: protocol/client behavior reference
- Nextcloud external storage
- https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage_configuration_gui.html
- why: storage aggregation behavior
- Nextcloud file sharing config
- https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/file_sharing_configuration.html
- why: share semantics reference
## What we steal vs what we own
### Steal
- Turborepo repo shape and task graph
- Next.js web-app conventions
- Go stdlib and proven Go infra libraries
- Go WebDAV implementation
- Finder native WebDAV mount UX
- Nextcloud shell-app and cloud/web primitives
### Own
- the betterNAS domain model
- the control-plane API
- the node registration and export model
- the mount profile model
- the mapping between cloud mode and mount mode
- the repo contract and shared schemas
- the root `pnpm verify` loop
## The first implementation slices after this scaffold
1. make `apps/node-agent` serve a real configurable WebDAV export
2. make `apps/control-plane` store real node/export records
3. issue real mount profiles from the control plane
4. make `apps/web` let a user pick an export and request a profile
5. keep `apps/nextcloud-app` thin and optional
