featurevisor-example-go

A small application showing how to use the Featurevisor Go SDK.

Learn more about Featurevisor here.

It fetches a production datafile, creates a Featurevisor instance with customer context, then evaluates:

• the commerce_platform feature as a flag;
• the checkout_experience variation;
• integer and array variables from checkout_experience;
• the serviceEndpoints global object variable into a Go struct;
• the supportContact global string variable.

The datafile comes from the Featurevisor Cloudflare example.

Requirements

• Go 1.21 or newer
• internet access for downloading the SDK and example datafile

Run the example

Install the dependencies:

go mod download

Run the application:

go run .

Expected output:

Commerce platform enabled: true
Checkout variation: express
Maximum checkout items: 25
Payment methods: [card wallet]
Service endpoint: https://api.eu.example.com (timeout: 1200 ms, retries: 4)
Support contact: support-nl@example.com

The evaluations use this context:

featurevisor.Context{
    "userId":      "customer-123",
    "country":     "nl",
    "locale":      "nl-NL",
    "accountPlan": "pro",
}

Change these values to see how Featurevisor selects different rules, variations, and global variable overrides.
