Hi guys! I’m having some package/module issues using the SDK in node (for a backend service). I’ve setup a typescript project, installed a bunch of dependencies and everything works (including building the app with tic) except loading the growthbook sdk at runtime. I’m getting the following error:

import { GrowthBook } from "@growthbook/growthbook";
     ^^^^^^^^^^
SyntaxError: Named export 'GrowthBook' not found. The requested module '@growthbook/growthbook' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@growthbook/growthbook';
const { GrowthBook } = pkg;

My IDE (Vscode) has no problem loading the sdk as an ES6 module. No other libs are causing any issues loading them with import. Just to humor node, I tried the suggestion and got the following error:

(node:20837) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
/Users/xxxx/node_modules/@growthbook/growthbook/dist/esm/index.js:1
export { GrowthBook } from "./GrowthBook";
^^^^^^

SyntaxError: Unexpected token 'export'

My tsconfig.json is as follows

 },
 "include": ["src/**/*", "__tests__/**/*"]
}

Versions: • `node`: 18.3.0 • `@growthbook/growthbook`: 0.18.0 • `tsc`: 4.7.2 Cmd to build is

tsc -p tsconfig.json

Cmd to run

node build/src/main.js

I spent a good deal of time yesterday trying to figure out the issue but to no avail. Any ideas/suggestions are much appreciated!

hey all, I'm testing out growthbook locally and had it working a bit, but now I keep hitting this error. Says it can't reach

<http://localhost:3100>

. Verified I can hit that url via curl

Hi guys~ Is there a helm chart to setup GrowthBook? currently we are planning to move it to EKS.

Hello Team. I started recently to use Growthbook in the Front-End (react). Now I stumble upon a problem with a unit test for a certain component; it actually validates if a component is being displayed. Since I added the “IfFeatureEnabled” component the test fails and I would like to know if there is a way of mocking its behaviour or something like this? Any help would be appreciated

Hello there! I'm wondering if there is a way to mock growthbook or force default values for features in local dev environments rather than hitting a real growthbook api. Is that possible ?

Is it possible to host Growthbook and Growthbook’s API in a single domain? The documentation for APP_ORIGIN and API_HOST specifies them to be different, but I wonder if I can host them in one domain but using a separate prefix instead (e.g. my-growthbook.com and my-growthbook.com/api)

Are you guys planning on making a WordPress Plugin?

Hi I'm having issues with using growthbook on AWS EC2, I setup the docker compose and I've changed the apihost and origin to the private IP of the EC2 (it needs to remain private) but its unable to fetch the api from myprivateip:3100.

Hi all can anyone tell me about tracking callback? In this section, we need to track an event to self tracker when feature impressed? Or just callback after GrowthBook tracked the feature?
