v4.0.0

What's Changed

• feat: Support transient identities and traits by @novakzaballa in #158
• feat!: Custom fetch support, remove node-fetch, ESM+CJS dual build, migrate to vitest, TS fixes, test improvements by @rolodato in #162
• feat!: Remove all uses of CJS, add named Flagsmith export by @rolodato in #163

BREAKING CHANGES

Node.js 18 or later is now required.

Flagsmith is now a named export and not a default export. This only changes how you import the Flagsmith Node.js SDK and not how you use it.

In 3.x and earlier, Flagsmith is the default export:

// ES modules
import Flagsmith from 'flagsmith-nodejs'

// CommonJS
const Flagsmith = require('flagsmith-nodejs')

In 4.x, you must use the named export:

// ES modules
import { Flagsmith } from 'flagsmith-nodejs'

// CommonJS
const { Flagsmith } = require('flagsmith-nodejs')
