Types

type ConflictError added in v0.2.0 

type ConflictError struct {
	ServerNote *Note
}

ConflictError is returned when the server's stored version is newer than the client's base version. It carries the current server note so the handler can return it in the 409 body, allowing the client to resolve the conflict and re-push without an extra round trip.

func (*ConflictError) Error added in v0.2.0 

func (e *ConflictError) Error() string

type Note 

type Note struct {
	ID               uuid.UUID  `gorm:"column:note_id;primaryKey;type:uuid"`

}

type NoteCursor 

type NoteCursor struct {
	AfterUpdatedAt time.Time `json:"updated_at"`

}

NoteCursor is the position marker for cursor-based pagination of notes, ordered by (updated_at ASC, note_id ASC).

func (r *NotesRepository) FindTombstonesSincePaginated(ctx context.Context, userID uuid.UUID, since time.Time, limit int, afterDeletedAt time.Time, afterNoteID uuid.UUID) ([]NoteTombstone, error)

FindTombstonesSincePaginated returns up to limit tombstones for the user whose deleted_at is strictly greater than since, ordered by (deleted_at ASC, note_id ASC). Pass zero values for afterDeletedAt and afterNoteID to start from the first page. Pass the last page's deleted_at and note_id to continue from a previous page.

Pass zero values for afterUpdatedAt and afterNoteID to start from the first page. Pass the last page's updated_at and note_id to continue from a previous page.

func (*NotesRepository) Purge added in v0.2.0 

func (r *NotesRepository) Purge(ctx context.Context, noteID uuid.UUID, userID uuid.UUID) error

Purge hard-deletes a note row and creates a NoteTombstone within a single transaction. Returns ErrNoteNotFound if no matching row exists for the given noteID and userID.

func (*NotesRepository) PurgeExpiredTombstones 

func (r *NotesRepository) PurgeExpiredTombstones(ctx context.Context, olderThan time.Time) (int64, error)

func (*NotesRepository) Restore added in v0.2.0

func (*NotesRepository) Trash added in v0.2.0 

func (r *NotesRepository) Trash(ctx context.Context, noteID uuid.UUID, userID uuid.UUID) error

Trash soft-deletes a note by setting trashed_at to the current time. Returns ErrNoteNotFound if no matching row exists for the given noteID and userID.

func (*NotesRepository) Upsert 

func (r *NotesRepository) Upsert(ctx context.Context, note *Note) error

type NotesService 

type NotesService struct {
	// contains filtered or unexported fields
}

NotesService implements business logic for note operations.

func NewNotesService 

func NewNotesService(repository repository, usersRepo usersRepository, freeNoteLimit int) *NotesService

NewNotesService constructs a NotesService. usersRepo is used to look up user plans for quota enforcement. freeNoteLimit is the maximum number of live notes allowed for free-plan users.

func (*NotesService) GetNoteByID 

func (s *NotesService) GetNoteByID(ctx context.Context, noteID uuid.UUID, userID uuid.UUID) (*Note, error)

func (*NotesService) GetNotesSince 

func (s *NotesService) GetNotesSince(ctx context.Context, userID uuid.UUID, since *time.Time, cursor *NoteCursor, limit int) ([]Note, []NoteTombstone, bool, error)

GetNotesSince returns notes and tombstones for the user.

When since is non-nil (delta sync), notes updated after that time are returned paginated using cursor-based keyset pagination ordered by (updated_at ASC, note_id ASC). Tombstones are likewise paginated by (deleted_at ASC, note_id ASC). Pass a non-nil cursor to continue from a previous page. hasMore is true when there are additional pages to fetch.

When since is nil (full sync), notes are paginated using the same cursor-based mechanism but across all notes, and all tombstones are returned on the first page only.

func (*NotesService) PurgeNote added in v0.2.0 

func (s *NotesService) PurgeNote(ctx context.Context, noteID uuid.UUID, userID uuid.UUID) error

PurgeNote hard-deletes a note and creates a tombstone for sync clients.

func (*NotesService) RestoreNote added in v0.2.0 

func (s *NotesService) RestoreNote(ctx context.Context, noteID uuid.UUID, userID uuid.UUID) (*Note, error)

RestoreNote clears the trashed_at timestamp and returns the updated note.

func (*NotesService) TrashNote added in v0.2.0 

func (s *NotesService) TrashNote(ctx context.Context, noteID uuid.UUID, userID uuid.UUID) error

TrashNote soft-deletes a note by setting its trashed_at timestamp.

func (*NotesService) UpsertNote 

func (s *NotesService) UpsertNote(ctx context.Context, userID uuid.UUID, noteID uuid.UUID, encryptedPayload []byte, baseVersion *time.Time) (*Note, error)

UpsertNote creates or updates a note for the given user.

When baseVersion is non-nil, the operation is treated as a versioned update: a conflict check is performed and quota is never enforced (the user is not adding a new note). When baseVersion is nil, the method first checks whether the note already exists:

  • If it exists, this is a re-push of an existing note — quota is not enforced and no conflict check is applied.
  • If it does not exist, this is a new-note create — quota is enforced for free-plan users before the upsert is attempted.

type TombstoneResponse 

type TombstoneResponse struct {
	NoteID    uuid.UUID  `json:"note_id"`
	DeletedAt *time.Time `json:"deleted_at"`
}

type UpsertNoteRequest 

type UpsertNoteRequest struct {
	EncryptedPayload string     `json:"encrypted_payload" validate:"required"`
	BaseVersion      *time.Time `json:"base_version"` // the updated_at the client last saw; omit on first write
}

type UserPlan added in v0.2.0 

type UserPlan struct {
	Plan string
}

UserPlan holds the subset of user data needed for quota enforcement. It is a value type so that the notes package does not import the users package.
