Types

type ContextLogger

type ContextLogger interface {
	Debugf(ctx context.Context, format string, args ...interface{})
	Infof(ctx context.Context, format string, args ...interface{})
	Warningf(ctx context.Context, format string, args ...interface{})
	Errorf(ctx context.Context, format string, args ...interface{})
}

ContextLogger interface used in this package with request context.

func NewContextLogger

func NewContextLogger(lev LogLevel) ContextLogger

NewContextLogger ...

type Firestore

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

Firestore is a DocumentStore implemented on Google Cloud Firestore.

func New

func New(uri string, opts ...option.ClientOption) (*Firestore, error)

New creates a Firestore

Example
url := "firestore://chilltest-3297b"
collection := "test"

opts := []option.ClientOption{option.WithCredentialsFile("credentials.json")}
fs, err := New(url, opts...)
if err != nil {
	log.Fatal(err)
}

exists, err := fs.Exists(context.TODO(), dstore.Path(collection, "key1"))
if err != nil {
	log.Fatal(err)
}
if exists {
	if _, err := fs.Delete(context.TODO(), dstore.Path(collection, "key1")); err != nil {
		log.Fatal(err)
	}
}

if err := fs.Create(context.TODO(), dstore.Path(collection, "key1"), dstore.Data([]byte("value1"))); err != nil {
	log.Fatal(err)
}

entry, err := fs.Get(context.TODO(), dstore.Path(collection, "key1"))
if err != nil {
	log.Fatal(err)
}

fmt.Printf("%s\n", entry.Path)
fmt.Printf("%s\n", entry.Data())
Output:

/test/key1
value1

func (*Firestore) Create

func (f *Firestore) Create(ctx context.Context, path string, values map[string]interface{}) error

Create document.

Paths can be nested as long as they are even length components. For example,

DocumentIterator ...

func (*Firestore) Documents

func (f *Firestore) Documents(ctx context.Context, parent string, opt ...dstore.Option) ([]*dstore.Document, error)

Documents not implemented on Firestore, use DocumentIterator.

func (*Firestore) EventAdd

func (f *Firestore) EventAdd(ctx context.Context, path string, doc events.Document) (int64, error)

func (*Firestore) EventPosition

func (f *Firestore) EventPosition(ctx context.Context, path string) (*events.Position, error)

func (*Firestore) EventPositions

func (f *Firestore) EventPositions(ctx context.Context, paths []string) (map[string]*events.Position, error)

EventPositions returns positions for event logs.

func (*Firestore) EventsAdd

func (f *Firestore) EventsAdd(ctx context.Context, path string, docs []events.Document) (int64, error)

func (*Firestore) EventsDelete

func (f *Firestore) EventsDelete(ctx context.Context, path string) (bool, error)

EventsDelete removes events.

func (*Firestore) Exists

func (f *Firestore) Exists(ctx context.Context, path string) (bool, error)

Exists returns true if path exists.

func (*Firestore) Load

func (f *Firestore) Load(ctx context.Context, path string, v interface{}) (bool, error)

Load path into value.

func (*Firestore) Set

func (f *Firestore) Set(ctx context.Context, path string, values map[string]interface{}, opt ...dstore.SetOption) error

Set document. Will create or set, overwriting any existing data.
