Server side validation for simple rest client

I have used swizzle on the simple rest api. How do I extend it to support server-side validation

Hi @Todilo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To implement server-side validation with the simple REST data provider in refine, you can extend the data provider by overriding specific functions. Here's how you can do it: 1. First, import the simple REST data provider:

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

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

2. Then, create a new data provider that extends the simple REST provider:

const simpleRestProvider = dataProvider("API_URL");
const myDataProvider = {
  ...simpleRestProvider,
  create: async ({ resource, variables, meta }) => {
    try {
      return await simpleRestProvider.create({ resource, variables, meta });
    } catch (error) {
      if (error.statusCode === 400 && error.errors) {
        // Transform the error to match the HttpError interface
        throw {
          message: error.message,
          statusCode: error.statusCode,
          errors: error.errors
        };
      }
      throw error;
    }
  },
};

const simpleRestProvider = dataProvider("API_URL");
const myDataProvider = {
  ...simpleRestProvider,
  create: async ({ resource, variables, meta }) => {
    try {
      return await simpleRestProvider.create({ resource, variables, meta });
    } catch (error) {
      if (error.statusCode === 400 && error.errors) {
        // Transform the error to match the HttpError interface
        throw {
          message: error.message,
          statusCode: error.statusCode,
          errors: error.errors
        };
      }
      throw error;
    }
  },
};

3. Use this custom data provider in your Refine component:

<Refine dataProvider={myDataProvider} />

<Refine dataProvider={myDataProvider} />

This approach allows you to intercept the response from your API, handle any validation errors, and transform them into the format that refine expects for server-side validation. The key is to ensure that the error object thrown matches the HttpError interface used by refine, which includes message, statusCode, and errors properties. For more detailed information on server-side validation in refine, you can refer to the Server Side Validation documentation. Remember to adjust the error handling logic to match the specific error format returned by your API.
