@moredip/openfeature-minimalist-provider

An extremely simple OpenFeature provider, intended for simple demos and as a test stub.

Flag values are entirely static - evaluation context is ignored and there's no way to update the flags at runtime.

Only supports boolean and string flags.

Getting started

install it

npm install @moredip/openfeature-minimalist-provider @openfeature/js-sdk note that @openfeature/js-sdk is a required peer dependency

set up the provider with some flag values

import { MinimalistProvider } from '@moredip/openfeature-minimalist-provider'
import { OpenFeature } from '@openfeature/js-sdk'

const flags = {
  'a-boolean-flag': true,
  'a-string-flag': 'the flag value',
}
const provider = new MinimalistProvider(flags)
OpenFeature.setProvider(provider)

check a flag's value

// create a client
const client = OpenFeature.getClient('my-app');

// get a bool value
const boolValue = await client.getBooleanValue('a-boolean-flag', false);
