const API_URL = process.env.CAFE24_API_URL
...

return (
<RefineKbarProvider>

_app.tsx

customergroups/index.tsx
const url = useApiUrl('default')
console.log(url) // undefined

Hi @florent. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the extracts, it's not clear why useApiUrl is returning undefined. However, it's important to note that useApiUrl is a hook provided by Refine to get the API URL of the data provider. It should return the API URL that you have set in your dataProvider in the Refine component. In your case, you have set the dataProvider as { default: dataProvider(API_URL!) }. So, useApiUrl('default') should return the API_URL value. If it's returning undefined, it could be due to several reasons: 1. The API_URL is not correctly set or not available at the time of the execution. 2. There might be an issue with the dataProvider configuration. 3. The useApiUrl hook is not used inside a component that is a child of the Refine component. Unfortunately, without more context or code, it's hard to pinpoint the exact issue. I would recommend checking the points mentioned above. If the issue persists, you might want to refer to the official Refine documentation (https://refine.dev/docs) or seek help from the Refine community. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai So does this mean that passing useApiUrl from _app.tsx to another index.tsx is not allowed? @kapa.ai So does this mean that passing useApiUrl from _app.tsx to another index.tsx is not allowed?

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the information provided in the extracts, the useApiUrl hook should be used inside a component that is a child of the Refine component. This is because hooks in React share the context of the component they are used in, and useApiUrl relies on the context provided by the Refine component. If you're trying to use useApiUrl in index.tsx which is not a child of the Refine component in _app.tsx, it might not work as expected. Ensure that the component where you're using useApiUrl is rendered inside the Refine component. If index.tsx is a page that is rendered outside the Refine component, useApiUrl will not be able to access the context and hence return undefined. If you need to pass the API URL to a component outside of the Refine context, consider passing it directly as a prop or using another state management solution. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to props surving _app.tsx to another index.tsx
kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- In Next.js, the _app.tsx file is used to initialize pages. You can't directly pass props from _app.tsx to another page like index.tsx. However, you can use global state management libraries like Redux or Context API to share state across different pages. Here's a basic example of how you can use Context API to share state: First, create a context:
import React from 'react';

export const ApiUrlContext = React.createContext(null);
import React from 'react';

export const ApiUrlContext = React.createContext(null);
Then, in your _app.tsx, provide the context:
import { ApiUrlContext } from './context';

// ...

function App({ Component, pageProps }: AppProps) {
const API_URL = process.env.CAFE24_API_URL;

// ...

return (
<ApiUrlContext.Provider value={API_URL}>
<Refine
// ...
>
<Component {...pageProps} />
</Refine>
</ApiUrlContext.Provider>
);
}

export default App;
import { ApiUrlContext } from './context';

// ...

function App({ Component, pageProps }: AppProps) {
const API_URL = process.env.CAFE24_API_URL;

// ...

return (
<ApiUrlContext.Provider value={API_URL}>
<Refine
// ...
>
<Component {...pageProps} />
</Refine>
</ApiUrlContext.Provider>
);
}

export default App;
Now, in your index.tsx, you can consume the context:
import { ApiUrlContext } from './context';

// ...

function IndexPage() {
const apiUrl = React.useContext(ApiUrlContext);

// ...

return (
// ...
);
}

export default IndexPage;
import { ApiUrlContext } from './context';

// ...

function IndexPage() {
const apiUrl = React.useContext(ApiUrlContext);

// ...

return (
// ...
);
}

export default IndexPage;
In this example, apiUrl in IndexPage will have the value of API_URL from _app.tsx. Please note that this is a simplified example. Depending on your application structure and requirements, you might need to adjust it. For more complex state management, consider using libraries like Redux or Zustand. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai const API_URL = process.env.CAFE24_API_URL Can't I use process.env in _app.tsx?

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can use process.env in _app.tsx to access environment variables. However, you need to ensure that the environment variable CAFE24_API_URL is correctly set in your environment. In Next.js, you can add environment variables in a .env.local file in the root of your project. These variables will then be loaded into the Node.js process. Here's an example of how you can set CAFE24_API_URL:
CAFE24_API_URL='your_api_url_here'
CAFE24_API_URL='your_api_url_here'
After setting the environment variable, you need to restart your development server to make sure the new environment values take effect. Then, in your _app.tsx, you can access the environment variable like this:
const API_URL = process.env.CAFE24_API_URL;
const API_URL = process.env.CAFE24_API_URL;
Please note that in order to expose a variable to the browser, you have to prefix the variable with NEXT_PUBLIC_. Any other variables are only available in the Node.js environment, meaning they won't be exposed to the browser. For more information, you can refer to the Next.js documentation on environment variables (https://nextjs.org/docs/basic-features/environment-variables). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Hello @florent, what is your data provider ? If you are using vite, env variables should be used like this https://vitejs.dev/guide/env-and-mode
