featurevisor-example-elixir

A small Elixir application showing how to consume the published Featurevisor Elixir SDK from Hex.pm.

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;
• the supportContact global string variable.

Requirements

Elixir 1.15 or newer.

Run the example

mix deps.get
mix run -e 'FeaturevisorExampleElixir.run()'

The datafile comes from the Featurevisor Cloudflare example:

https://featurevisor-example-cloudflare.pages.dev/production/featurevisor-sdk-v3.json

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 important SDK usage is in lib/featurevisor_example_elixir.ex. Change its context values to see how Featurevisor selects different rules, variations, and global variable overrides.

The featurevisor dependency comes from Hex.pm. It is not a local path dependency, so this project demonstrates the same setup used by a new consumer.
