Hi everyone I need some help to initiate the growthbook project with vanilla nodejs So I iniciated a NodeJS v18 12 1 empty project to test the GrowthBook tool ```mkdir test cd test npm init y npm install save growthbook growthbook touch index js``` inside `index js` file I paste the Step 1 from the guide ```import GrowthBook from growthbook growthbook Create a GrowthBook instance const gb = new GrowthBook apiHost clientKey sdk key Enable easier debugging of feature flags during development enableDevMode true Wait for features to be available await gb loadFeatures autoRefresh true const color = gb getFeatureValue button color ``` When I executed `node index js` the terminal yield ``` node 38068 Warning To load an ES module set type module in the package json or use the mjs extension Use `node trace warnings ` to show where the warning was created tmp test index js 1 import GrowthBook from growthbook growthbook ^^^^^^ SyntaxError Cannot use import statement outside a module at Object compileFunction node vm 360 18 at wrapSafe node internal modules cjs loader 1088 15 at Module compile node internal modules cjs loader 1123 27 at Module extensions js node internal modules cjs loader 1213 10 at Module load node internal modules cjs loader 1037 32 at Module load node internal modules cjs loader 878 12 at Function executeUserEntryPoint as runMain node internal modules run main 81 12 at node internal main run main module 23 47 Node js v18 12 1``` Then I add this line to `package json` ``` type module ``` And run again the code This time the error message was this ``` tmp test index js 1 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 at ModuleJob instantiate node internal modules esm module job 123 21 at async ModuleJob run node internal modules esm module job 189 5 at async Promise all index 0 at async ESMLoader import node internal modules esm loader 530 24 at async loadESM node internal process esm loader 91 5 at async handleMainPromise node internal modules run main 65 12 Node js v18 12 1``` And then I change the `index js` file to this ```import pkg from growthbook growthbook const GrowthBook = pkg Create a GrowthBook instance const gb = new GrowthBook apiHost clientKey sdk key Enable easier debugging of feature flags during development enableDevMode true Wait for features to be available await gb loadFeatures autoRefresh true const color = gb getFeatureValue button color ``` And run the nodejs file again This time I received this error message ``` node 38721 Warning To load an ES module set type module in the package json or use the mjs extension Use `node trace warnings ` to show where the warning was created tmp test node modules growthbook growthbook dist esm index js 1 export setPolyfills clearCache configureCache from feature repository ^^^^^^ SyntaxError Unexpected token export at Object compileFunction node vm 360 18 at wrapSafe node internal modules cjs loader 1088 15 at Module compile node internal modules cjs loader 1123 27 at Module extensions js node internal modules cjs loader 1213 10 at Module load node internal modules cjs loader 1037 32 at Module load node internal modules cjs loader 878 12 at ModuleWrap lt anonymous gt node internal modules esm translators 169 29 at ModuleJob run node internal modules esm module job 193 25 at async Promise all index 0 at async ESMLoader import node internal modules esm loader 530 24 Node js v18 12 1``` Can get any help

Hi < microscopic refrigerator 66345> For vanilla Node js you should use the CommonJS style of importing instead e g `const GrowthBook = require growthbook growthbook GrowthBook` Our We don t support ESM imports currently If I may ask do you know what sort of project you intend to use GrowthBook for Typically our SDK is used with a web server such as Express You might have a better time trying out GrowthBook by setting up a web server in Node js first and then installing GrowthBook onto it

```const GrowthBook = require growthbook growthbook GrowthBook Create a GrowthBook instance const gb = new GrowthBook apiHost <https cdn growthbook io> clientKey sdk key Enable easier debugging of feature flags during development enableDevMode true Wait for features to be available gb loadFeatures autoRefresh true then = gt const color = gb getFeatureValue button color console log color color ```
