Firebase utils for golang

Tools that make it easier to work with Google Cloud / Firebase's Firestore.

Go Reference

For instance:

ob := &MyObject{}
err := firetils.Save(ctx, client, "myCollection", ob) // depending on interfaces on the object, it will update timestamps, call PreSave() function, etc

Fetching:

There's several functions here, they will all call populate into a struct and call AfterLoad().

firetils.GetByID
firetils.GetOneByQuery
firetils.GetAllByQuery

Data Handling

Add TimeStamped and Firestored to your objects, eg:

type X struct {
    firetils.Firestored
    firetils.TimeStamped
    firetils.IDed
}

You can do pre-saving and after-loading by adding PreSave(ctx context.Context) and/or AfterLoad(ctx context.Context) function to your models.

Authentication

Authenticate function will validate an auth token.

Or use firetils.FireAuth middleware to do it automatically.

Functions

func Authenticate 

func Authenticate(ctx context.Context, firebaseAuth *fauth.Client, w http.ResponseWriter, r *http.Request, hardVerify bool) (*fauth.Token, error)

Authenticate checks the Authorization header for a firebase token

func Collection 

func Collection(client *firestore.Client, name string) *firestore.CollectionRef

Collection returns CollectionRef by name

func CreateSession added in v0.0.40 

func CreateSession(auth *auth.Client, r *http.Request) (token string, response map[string]any, err error)
	return gotils.WriteObject(w, http.StatusOK, resp)
}

func Delete 

func Delete(ctx context.Context, client *firestore.Client, collectionName, id string) error

GetByID get a doc by ID

func EnsureUserDefault added in v0.0.40 

func EnsureUserDefault(ctx context.Context, auth *auth.Client, fs *firestore.Client, idToken, usersCollection string) (*auth.UserRecord, error)

This will verify the idToken, fetch the user from firebase auth, then update the 'usersCollection' with, email, name and image IF it doesn't already exist. TODO: Will update those fields if they have changed.

func FireAuth 

func FireAuth(next http.Handler) http.Handler

FireAuth middleware to guard endpoints

func GetAllByQuery 

func GetAllByQuery(ctx context.Context, q firestore.Query, limit int, ret []interface{}) error

GetAllByQuery generic way to get a list of documents. NOTE: this doesn't seem to work well, best to use GetAllByQuery2. limit param restricts how many are returned. <=0 is all results. ret will be filled with the objects Deprecated: use GetAllByQuery2+

func GetAllByQuery3 added in v0.0.41 

func GetAllByQuery3[T StoredAndStamped](ctx context.Context, q firestore.Query, v T) ([]T, error)

func GetByID 

func GetByID(ctx context.Context, client *firestore.Client, collectionName, id string, t StoredAndStamped) error

GetByID get a doc by ID

func GetByRef 

func GetByRef(ctx context.Context, client *firestore.Client, ref *firestore.DocumentRef, t StoredAndStamped) error

GetByRef generic way to get a document

func GetOneByQuery 

func GetOneByQuery(ctx context.Context, q firestore.Query, t StoredAndIded) error

GetOneByQuery generic way to get a document

func New 

func New(ctx context.Context, projectID string, opts []option.ClientOption) (*firebase.App, error)

New creates a new firestore client Call defer client.Close() after this if you can

func NewFireHolder 

func NewFireHolder(ctx context.Context, app *firebase.App) *fireHolder

NewFireHolder don't use this yet This is intended to be a way to have multiple firetils instance with different configs, rather than globals

func OptionalAuth 

func OptionalAuth(next http.Handler) http.Handler

OptionalAuth this won't guard it, but will set the token in the context if it's there. Will not error out if it's not there.

func Save3 added in v0.0.41 

func Save3(ctx context.Context, client *firestore.Client, collection string, v StoredAndStamped) error

func Save3WithOpts added in v0.0.41 

func Save3WithOpts(ctx context.Context, client *firestore.Client, collection string, v StoredAndStamped, opts *SaveOptions) error

func SetOwned 

func SetOwned(ctx context.Context, o OwnedI)

func Token 

func Token(ctx context.Context) *fauth.Token

func UserID 

func UserID(ctx context.Context) string
