How to use localhost as a data provider? I have a restfull api backend running, but changing the dataProvider to "localhost:3333" didn't work. By backend is responding correclty as I can see in postman and in the browser. Can someone help? I would appreciate.

Hey @henriquebarcelos! I'm the kapa.ai support bot. I've searched through the docs to try to answer your question. :wave:

---------------------- To use your localhost as a data provider in refine, you need to follow these steps: 1. Install the refine-simple-rest data provider package if you haven't already, as it's suitable for communicating with RESTful APIs. You can install it using the following command:

npm install @refinedev/simple-rest

npm install @refinedev/simple-rest

2. Import the data provider in your _app.tsx or App.tsx file and configure it with your API URL:

import dataProvider from "@refinedev/simple-rest";

const API_URL = "http://localhost:3333";

import dataProvider from "@refinedev/simple-rest";

const API_URL = "http://localhost:3333";

3. Pass the data provider to the <Refine> component:

import { Refine } from "@refinedev/core";

const App: React.FC = () => {
  return (
    <Refine dataProvider={dataProvider(API_URL)}>
      {/* ... */}
    </Refine>
  );
};

import { Refine } from "@refinedev/core";

const App: React.FC = () => {
  return (
    <Refine dataProvider={dataProvider(API_URL)}>
      {/* ... */}
    </Refine>
  );
};

Make sure to replace localhost:3333 with the correct address and port where your backend is running. If you still face issues, ensure that your API follows the expected format and structure required by the refine-simple-rest data provider. You can refer to the refine-simple-rest source code (https://github.com/refinedev/refine/tree/next/packages/simple-rest) for more information. If your API doesn't follow the expected format, you might need to create a custom data provider or modify the existing one using the swizzle command. You can learn more about creating a custom data provider from scratch in the refine documentation (https://refine.dev/docs/tutorial/understanding-dataprovider/create-dataprovider). ----------------------

passive-yellowOP•2y ago

It keeps loading forever

passive-yellowOP•2y ago

Here you can see it is working

adverse-sapphire•2y ago

can you give me your network output please. request and response payload and did you try http://localhost:3333 this ?

passive-yellowOP•2y ago

Yes! Like this: dataProvider={dataProvider("http://localhost:3333")}

can you check resource name please

passive-yellowOP•2y ago

I thought path="" could be anything. But I updated to locais-coleta and the error is this one:

passive-yellowOP•2y ago

Thanks for your help in advance.

adverse-sapphire•2y ago

is it worked ? 🤔

passive-yellowOP•2y ago

No. I think I should have mentioned I'm using the tutorial template. Does it matter?

adverse-sapphire•2y ago

i don't think so. can you give me network data again 404 ones

passive-yellowOP•2y ago

Maybe refine is trying to get a paginated response from the server?

adverse-sapphire•2y ago

it should be /locais_coleta isn't it ?

passive-yellowOP•2y ago

Sure! Updating

adverse-sapphire•2y ago

okey this is a react issue. you can't use objects as a react child https://stackabuse.com/bytes/fix-objects-are-not-valid-as-a-react-child-error-in-react/ this is seems good article

passive-yellowOP•2y ago

So refine doesn't support nested json objects? I have json responses that are not nested, but it sill doesn't work. For example, a response like:

    {
        "id": 1,
        "nome": "Nome atualizado",
        "rua": "Rua dos Testes",
        "numero": "123",
        "complemento": "Opcional",
        "documento": "123.456.789-00",
        "cidade_id": 1,
        "tipo_id": 4,
        "created_at": "2023-03-26T01:41:06.420Z",
        "updated_at": "2023-03-26T01:55:53.062Z"
    }
]

    {
        "id": 1,
        "nome": "Nome atualizado",
        "rua": "Rua dos Testes",
        "numero": "123",
        "complemento": "Opcional",
        "documento": "123.456.789-00",
        "cidade_id": 1,
        "tipo_id": 4,
        "created_at": "2023-03-26T01:41:06.420Z",
        "updated_at": "2023-03-26T01:55:53.062Z"
    }
]

it's not a refine issue and it's not about API data. it's about react and JSX. and it's not about nested objects i think that article above is very good

passive-yellowOP•2y ago

I tried to implement but I still don't know how to map it since the .tsx file doesn't have html directly in it. What steps do you recommend for me to do to solve this problem? Thanks!

adverse-sapphire•2y ago

yes react works with jsx instead of html. i suggest you should read or watch react tutorials. https://react.dev/ probably react official documentation is the best. refine is a pure react framework and this topic only about react

passive-yellowOP•2y ago

Just to make sure I understand. Are you saying I need to adapt refine to read the json response in another way?

adverse-sapphire•2y ago

no, i mean this error react related not refine. but, I just saw that you are using inferencer. Is this error coming from inferencer ? if it is, probably inferencer generated wrong code

passive-yellowOP•2y ago

I'd suggest you testing localhost with some different jsons, because I found some misinterpretations of the it. I had to manually correct some mapping. My json is fine, maybe your methods of scrapping objects is not completely correct.

adverse-sapphire•2y ago

It's possible. Can you give us data for debug
