Functions

func About

func About() echo.HandlerFunc

func Auth

func Auth() func(echo.Context) error

Auth redirects the user to the fitbit authorization page It sets a cookie the univocally identifies the user because the authorizer.Exchange (used in Redirect) needs to check the `code` and CSRF tokens - and these tokens are attributes of the fitbit client that needs to persist from Auth() to Redirect(). NOTE: it uses the environment variables: - FITBIT_CLIENT_ID - FITBIT_CLIENT_SECRET - FITBIT_REDIRECT_URL Loaded from a .env file - if any.

func ChatWithData

func ChatWithData() echo.HandlerFunc

func Contact

func Contact() echo.HandlerFunc

func CustomDashboard

func CustomDashboard() echo.HandlerFunc

func Dump

func Dump() echo.HandlerFunc

func Error

func Error() func(echo.Context) error

func Fetch

func Fetch() echo.HandlerFunc

func GenerateTypes

func GenerateTypes() echo.HandlerFunc

GenerateTypes is an internal use endpoint That allows to have a Go representation of the JSON responses for all the GET endpoints of the Fitbit API. It doesn't use the authorizer methods, because it has been used to create the types used by the authorizer itself.

func GetStartDayOfWeek

func GetStartDayOfWeek(tm time.Time) time.Time

func Index

func Index() echo.HandlerFunc

func MonthlyDashboard

func MonthlyDashboard() echo.HandlerFunc

func NewDumper

func NewDumper(accessToken string) (*dumper, error)

NewDumper creates a new dumper using the provided access token

func NewFetcher

func NewFetcher(user *types.User) (*fetcher, error)

NewFetcher creates a new fetcher for the provided user

func NewRouter

func NewRouter() (*echo.Echo, error)

func PredictSleepEfficiency

func PredictSleepEfficiency(user *types.User, userData []*UserData) ([]uint8, error)

func Privacy

func Privacy() echo.HandlerFunc

func Redirect

func Redirect() func(echo.Context) error

Redirect handles the redirect from the Fitbit API to our redirect URI. Sets the "token" cookie for the whole domain, containing the access token The access token univocally identifies the user. The token expires when the access token expires.

func RequireFitbit

func RequireFitbit() echo.MiddlewareFunc

RequireFitbit is the middleware to use when a route requires to interact with the fitbit API. The middleware uses the cookies to identify the user and understand in which phase of the oauth2 authorization flows we are and set the context's fitbit variable (c.Get("fitbit")) to a valid authorizer If and only if the required cookies have been previously set.

func TestGET

func TestGET() echo.HandlerFunc

func TestPredictSleepEfficiency

func TestPredictSleepEfficiency() echo.HandlerFunc

func TestTrainAndDeploy

func TestTrainAndDeploy() echo.HandlerFunc

func TrainAndDeployPredictor

func TrainAndDeployPredictor(user *types.User, targetColumn string) (err error)

func UserDataToPredictionInstance

func UserDataToPredictionInstance(userData []*UserData, skipColumns []string) ([]*structpb.Value, error)

UserDataToPredictionInstance converts a slice of UserData to a slice of structpb.Value. It skips all the columns that are not used for training, that you should pass in the skipColumns parameter.

func WeeklyDashboard

func WeeklyDashboard() echo.HandlerFunc

func YearlyDashboard

func YearlyDashboard() echo.HandlerFunc
