Functions

func BodyOrEmptyJsonObj

func BodyOrEmptyJsonObj(c *fiber.Ctx) []byte

BodyOrEmptyJsonObj returns request body or an empty JSON object buffer otherwise.

func ComputeDeviceId

func ComputeDeviceId(bytesSlice ...[]byte) uint64

ComputeDeviceId computes xxh3 hash of the given byte slices. This is the same as Xxh3 function.

func ComputeVisitorId

func ComputeVisitorId(bytesSlice ...[]byte) string

ComputeVisitorId computes xxh3 hash of the given byte slices and adds result as hexadecimal suffix to "prisme_".

func ContextTimeout

func ContextTimeout(ctx context.Context) time.Duration

ContextTimeout extract duration until context timeout and panics if no deadline is found.

func ExtractClientHints

func ExtractClientHints(headers *fasthttp.RequestHeader, client *uaparser.Client)

ExtractClientHints parses Sec-Ch-Ua-XXX headers and adds them to the given *uaparser.Client.

func ExtractUtmParams

func ExtractUtmParams(args *fasthttp.Args) event.UtmParams

ExtractUtmParams extracts UTM parameters from the given query args. If no utm_source arg is found, it fallbacks to ref arg.

func PeekAndParseReferrerHeader

func PeekAndParseReferrerHeader(c *fiber.Ctx) (uri.Uri, error)

PeekAndParseReferrerHeader retrieves and parses prisme or standard referrer header. In case of error, a fiber error with status 400 bad request is returned.

func PeekAndParseReferrerQueryHeader

func PeekAndParseReferrerQueryHeader(c *fiber.Ctx) (uri.Uri, error)

PeekAndParseReferrerHeader retrieves and parses referrer from query parameter or standard header. In case of error, a fiber error with status 400 bad request is returned.

func PeekReferrerHeader

func PeekReferrerHeader(c *fiber.Ctx) []byte

PeekReferrerHeader peek X-Prisme-Referrer header and fallback to standard Referer header otherwise.

func PeekReferrerQueryOrHeader

func PeekReferrerQueryOrHeader(c *fiber.Ctx) []byte

PeekReferrerQueryOrHeader peek referrer from "referrer" query parameter and fallback to standard Referer header otherwise.

func Xxh3

func Xxh3(bytesSlice ...[]byte) uint64

Xxh3 computes xxh3 hash of the given byte slices.
