GrowthBook

Load a GrowthBook feature’s evaluated value as config.


Scheme	`growthbook://`
Module	`github.com/xavidop/mamori/providers/growthbook`
Sensitive	no
Watch	poll
Auth	GrowthBook client key + API host

Install

go get github.com/xavidop/mamori/providers/growthbook

import _ "github.com/xavidop/mamori/providers/growthbook"

Using the ref

A growthbook:// ref points at one feature key. It resolves to that feature’s evaluated value.

growthbook://<feature-key>[#json-key]

Part	Required	What it means
`<feature-key>`	yes	The GrowthBook feature key.
`#json-key`	no	Select one field from a JSON feature value (via SelectKey).

The value maps to bytes by type (boolean, string, number, or JSON). A feature not present in the loaded feature set resolves to not-found.

Examples

growthbook://dark-mode resolves to true / false.
growthbook://checkout-config#timeout_ms resolves to the timeout_ms field of a JSON feature value.

Watch

GrowthBook loads its features from the API and refreshes them; mamori polls (WithPollInterval + jitter).

Configuration

import gbprov "github.com/xavidop/mamori/providers/growthbook"

mamori.WithProvider(gbprov.New(
	gbprov.WithClientKey(os.Getenv("GROWTHBOOK_CLIENT_KEY")),
	gbprov.WithAPIHost("https://cdn.growthbook.io"),
))

Verified with an injected fake (un-seeded features resolve to not-found); live behavior is covered by //go:build integration tests.
