Types

type AnalyticsProcessor 

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

func NewAnalyticsProcessor 

func NewAnalyticsProcessor(ctx context.Context, client flaghttp.Client, baseURL string, timerInMilli *int, log Logger) *AnalyticsProcessor

func (*AnalyticsProcessor) Flush 

func (a *AnalyticsProcessor) Flush(ctx context.Context) error

func (*AnalyticsProcessor) TrackFeature 

func (a *AnalyticsProcessor) TrackFeature(featureName string)

type Client 

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

Client provides various methods to query Flagsmith API.

func NewClient 

func NewClient(apiKey string, options ...Option) *Client

NewClient creates instance of Client with given configuration.

func (*Client) BulkIdentify 

func (c *Client) BulkIdentify(ctx context.Context, batch []*IdentityTraits) error

BulkIdentify can be used to create/overwrite identities(with traits) in bulk NOTE: This method only works with Edge API endpoint.

func (*Client) GetEnvironmentFlags 

func (c *Client) GetEnvironmentFlags(ctx context.Context) (f Flags, err error)

Returns `Flags` struct holding all the flags for the current environment.

If local evaluation is enabled this function will not call the Flagsmith API directly, but instead read the asynchronously updated local environment or use the default flag handler in case it has not yet been updated.

func (*Client) GetEnvironmentFlagsFromAPI 

func (c *Client) GetEnvironmentFlagsFromAPI(ctx context.Context) (Flags, error)

GetEnvironmentFlagsFromAPI tries to contact the Flagsmith API to get the latest environment data. Will return an error in case of failure or unexpected response.

func (*Client) GetIdentityFlags 

func (c *Client) GetIdentityFlags(ctx context.Context, identifier string, traits []*Trait) (f Flags, err error)

Returns `Flags` struct holding all the flags for the current environment for a given identity.

If local evaluation is disabled it will also upsert all traits to the Flagsmith API for future evaluations. Providing a trait with a value of nil will remove the trait from the identity if it exists.

If local evaluation is enabled this function will not call the Flagsmith API directly, but instead read the asynchronously updated local environment or use the default flag handler in case it has not yet been updated.

func (*Client) GetIdentityFlagsFromAPI 

func (c *Client) GetIdentityFlagsFromAPI(ctx context.Context, identifier string, traits []*Trait) (Flags, error)

GetIdentityFlagsFromAPI tries to contact the Flagsmith API to get the latest identity flags. Will return an error in case of failure or unexpected response.

func (*Client) GetIdentitySegments 

func (c *Client) GetIdentitySegments(identifier string, traits []*Trait) ([]*segments.SegmentModel, error)

Returns an array of segments that the given identity is part of.

func (*Client) UpdateEnvironment 

func (c *Client) UpdateEnvironment(ctx context.Context) error

type Flag 

type Flag struct {
	Enabled     bool
	Value       interface{}
	IsDefault   bool
	FeatureID   int
	FeatureName string
}

type Flags 

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

func (*Flags) AllFlags 

func (f *Flags) AllFlags() []Flag

Returns an array of all flag objects.

func (*Flags) GetFeatureValue 

func (f *Flags) GetFeatureValue(featureName string) (interface{}, error)

Returns the value of a particular flag.

func (*Flags) GetFlag 

func (f *Flags) GetFlag(featureName string) (Flag, error)

Returns a specific flag given the name of the feature.

func (*Flags) IsFeatureEnabled 

func (f *Flags) IsFeatureEnabled(featureName string) (bool, error)

Returns a boolean indicating whether a particular flag is enabled.

type FlagsmithAPIError 

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

func (FlagsmithAPIError) Error 

func (e FlagsmithAPIError) Error() string

type FlagsmithClientError 

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

func (FlagsmithClientError) Error 

func (e FlagsmithClientError) Error() string

type IdentityTraits 

type IdentityTraits struct {
	Identifier string   `json:"identifier"`
	Traits     []*Trait `json:"traits"`
}

type LocalFileHandler added in v3.3.0 

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

func NewLocalFileHandler added in v3.3.0 

func NewLocalFileHandler(environmentDocumentPath string) (*LocalFileHandler, error)

NewLocalFileHandler creates a new LocalFileHandler with the given path.

func (*LocalFileHandler) GetEnvironment added in v3.3.0 

func (handler *LocalFileHandler) GetEnvironment() *environments.EnvironmentModel

type Logger 

type Logger interface {
	// Errorf logs an error message with the given format and arguments.
	Errorf(format string, v ...interface{})

	// Warnf logs a warning message with the given format and arguments.
	Warnf(format string, v ...interface{})

	// Debugf logs a debug message with the given format and arguments.
	Debugf(format string, v ...interface{})
}

Logger is the interface used for logging by flagsmith client. This interface defines the methods that a logger implementation must implement. It is used to abstract logging and enable clients to use any logger implementation they want.

type OfflineHandler added in v3.3.0 

type OfflineHandler interface {
	GetEnvironment() *environments.EnvironmentModel
}

type Option 

type Option func(c *Client)

func WithAnalytics 

func WithAnalytics(ctx context.Context) Option

WithAnalytics enables tracking of the usage of the Feature flags.

The goroutine responsible for asynchronously uploading the locally stored cache uses the context provided here, which means that if it expires the background process will exit.

func WithBaseURL 

func WithBaseURL(url string) Option

func WithCustomHeaders 

func WithCustomHeaders(headers map[string]string) Option

func WithDefaultHandler 

func WithDefaultHandler(handler func(string) (Flag, error)) Option

func WithEnvironmentRefreshInterval 

func WithEnvironmentRefreshInterval(interval time.Duration) Option

func WithLocalEvaluation 

func WithLocalEvaluation(ctx context.Context) Option

WithLocalEvaluation enables local evaluation of the Feature flags.

The goroutine responsible for asynchronously updating the environment makes use of the context provided here, which means that if it expires the background process will exit.

func WithLogger 

func WithLogger(logger Logger) Option

Allows the client to use any logger that implements the `Logger` interface.

func WithOfflineHandler added in v3.3.0 

func WithOfflineHandler(handler OfflineHandler) Option

WithOfflineHandler returns an Option function that sets the offline handler.

func WithOfflineMode added in v3.3.0 

func WithOfflineMode() Option

WithOfflineMode returns an Option function that enables the offline mode. NOTE: before using this option, you should set the offline handler.

func WithProxy 

func WithProxy(proxyURL string) Option

WithProxy returns an Option function that sets the proxy(to be used by internal resty client). The proxyURL argument is a string representing the URL of the proxy server to use, e.g. "http://proxy.example.com:8080".

func WithRemoteEvaluation 

func WithRemoteEvaluation() Option

func WithRequestTimeout 

func WithRequestTimeout(timeout time.Duration) Option

func WithRetries 

func WithRetries(count int, waitTime time.Duration) Option

type Trait struct {
	TraitKey   string      `json:"trait_key"`
	TraitValue interface{} `json:"trait_value"`
}

func (*Trait) ToTraitModel 

func (t *Trait) ToTraitModel() *traits.TraitModel
