Documentation

Overview

Package chromeuxreport provides access to the Chrome UX Report API.

For product documentation, see: https://developers.google.com/web/tools/chrome-user-experience-report/api/reference

Creating a client

Usage example:

import "google.golang.org/api/chromeuxreport/v1"
...
ctx := context.Background()
chromeuxreportService, err := chromeuxreport.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication.

For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:

chromeuxreportService, err := chromeuxreport.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
chromeuxreportService, err := chromeuxreport.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See https://godoc.org/google.golang.org/api/option/ for details on options.

Types

type Bin

type Bin struct {
	// Density: The proportion of users that experienced this bin's value
	// for the given metric.
	Density float64 `json:"density,omitempty"`

	// End: End is the end of the data bin. If end is not populated, then
	// the bin has no end and is valid from start to +inf.
	End interface{} `json:"end,omitempty"`

	// Start: Start is the beginning of the data bin.
	Start interface{} `json:"start,omitempty"`

	// ForceSendFields is a list of field names (e.g. "Density") to
	// unconditionally include in API requests. By default, fields with
	// empty values are omitted from API requests. However, any non-pointer,
	// non-interface field appearing in ForceSendFields will be sent to the
	// server regardless of whether the field is empty or not. This may be
	// used to include empty fields in Patch requests.
	ForceSendFields []string `json:"-"`

	// NullFields is a list of field names (e.g. "Density") to include in
	// API requests with the JSON null value. By default, fields with empty
	// values are omitted from API requests. However, any field with an
	// empty value appearing in NullFields will be sent to the server as
	// null. It is an error if a field in this list has a non-empty value.
	// This may be used to include null fields in Patch requests.
	NullFields []string `json:"-"`
}

Bin: A bin is a discrete portion of data spanning from start to end, or if no end is given, then from start to +inf. A bin's start and end values are given in the value type of the metric it represents. For example, "first contentful paint" is measured in milliseconds and exposed as ints, therefore its metric bins will use int32s for its start and end types. However, "cumulative layout shift" is measured in unitless decimals and is exposed as a decimal encoded as a string, therefore its metric bins will use strings for its value type.
