Simple REST

The Simple REST data provider is a package that provides an implementation for working with REST APIs that conform to a standard API design. It is built on the foundation of the json-server package.

You can use this data provider to quickly get started with Refine and then customize it to fit your specific needs.

Installation

npm i @refinedev/simple-rest

Usage

Simple REST package exports a function that accepts apiUrl and httpClient parameters. While apiUrl is required to set the base URL for your API endpoints, httpClient is optional and can be used to provide a custom axios instance to handle logics like authentication, error handling, etc.

app.tsx
import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/simple-rest";

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

URL design

The data provider methods are designed to work with REST APIs that follow the standard design. The following table shows the expected URL for each method:

MethodURLQuery ParametersBody
getListapiUrl / resourcepagination, sorters, filters
getOneapiUrl / resource / id
getManyapiUrl / resourceid
createapiUrl / resourcevariables
updateapiUrl / resource / idvariables
deleteOneapiUrl / resource / iddata: variables

Default HTTP methods and customizing them

The following table shows the HTTP method used for each data provider method:

MethodHTTP Method
getListGET
getOneGET
getManyGET
createPOST
updatePATCH
deleteOneDELETE

You can customize the HTTP method used for each data provider method by passing a method property in the meta parameter when calling a hook.

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

const { mutate } = useUpdate();

mutate({
resource: "posts",
id: 1,
values: {
title: "New title",
},
meta: {
method: "put",
},
});

Passing custom headers

You can pass custom headers to the data provider by passing a headers property in the meta parameter.

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

useOne({
resource: "posts",
id: 1,
meta: {
headers: {
"X-Custom-Header": "Custom header value",
},
},
});

Customizing the data provider
Check the guide
Please check the guide for more information on this topic.

In some cases, you may need to customize the data provider to work with a REST API that doesn't follow the simple-rest design. In this case, you can use the swizzle command to customize the data provider.

  1. Run the swizzle command in the project directory:

    npm run refine swizzle
  2. Select @refinedev/simple-rest from the list of available data providers.

  3. Edit the /rest-data-provider/index.ts file to customize the data provider.

  4. Pass the customized data provider to the dataProvider prop of the Refine component.

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

    import { dataProvider } from "./rest-data-provider";

    const App = () => {
    return (
    <Refine
    dataProvider={dataProvider("https://api.fake-rest.refine.dev")}
    /* ... */
    />
    );
    };
