How to work with different endpoint routes for one resource?

my api endpoint routes does not follow the standard REST Api way of having one route to hand all methods(post, get, put, etc.). in a resource, my list endpoint route can be "/gw/campaign/fetch" while my create endpoint can be "/gw/campaign/create" How can I make data provider work for me?

Hi @script4559. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In refine, the resource prop is usually used as an API endpoint path. This is passed to the dataProvider as a parameter. However, the way it is handled depends on your dataProvider implementation. If you want to change the API endpoint path for a specific resource, you would need to modify your dataProvider to handle this. The Data Provider is the bridge between your frontend and your backend data source. It is responsible for handling all data-related operations such as fetching, caching, creating, updating, and deleting records. Each data operation in the Data Provider is typically associated with a specific resource. For example, when fetching data for a products resource, the Data Provider will know which endpoint to hit and how to handle the response. Here's an example of a custom data provider:

import { DataProvider } from "@refinedev/core";  
  
const myDataProvider: DataProvider = {  
 getOne: async ({ resource, id }) => {  
 const response = await fetch(`<https://example.com/api/v1/${resource}/${id}`>);  
 const data = await response.json();  
  
 return { data };  
 },  
 // other methods...  
};

import { DataProvider } from "@refinedev/core";  
  
const myDataProvider: DataProvider = {  
 getOne: async ({ resource, id }) => {  
 const response = await fetch(`<https://example.com/api/v1/${resource}/${id}`>);  
 const data = await response.json();  
  
 return { data };  
 },  
 // other methods...  
};

In your case, you can customize the getOne, getList, getMany, create, update, delete methods in the dataProvider to use different endpoint paths for different operations. For example, you can define your getList and create methods like this:

const myDataProvider: DataProvider = {  
 getList: async ({ resource }) => {  
 const response = await fetch(`<https://example.com/api/v1/gw/${resource}/fetch`>);  
 const data = await response.json();  
  
 return { data };  
 },  
 create: async ({ resource, parameters }) => {  
 const response = await fetch(`<https://example.com/api/v1/gw/${resource}/create`,> {
   method: 'POST',
   body: JSON.stringify(parameters),
   headers: {
     'Content-Type': 'application/json'
   }
 });  
 const data = await response.json();  
  
 return { data };  
 },  
 // other methods...  
};

const myDataProvider: DataProvider = {  
 getList: async ({ resource }) => {  
 const response = await fetch(`<https://example.com/api/v1/gw/${resource}/fetch`>);  
 const data = await response.json();  
  
 return { data };  
 },  
 create: async ({ resource, parameters }) => {  
 const response = await fetch(`<https://example.com/api/v1/gw/${resource}/create`,> {
   method: 'POST',
   body: JSON.stringify(parameters),
   headers: {
     'Content-Type': 'application/json'
   }
 });  
 const data = await response.json();  
  
 return { data };  
 },  
 // other methods...  
};

@kapa.ai the method you are using is static, the endpoint route can take any form. What do you suggest I do

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In cases where your API endpoint routes can take any form and do not follow the standard REST API structure, you can create a more dynamic data provider. This would involve creating a function that generates the endpoint URL based on the resource and action type. Here's an example of how you might implement this:

const myDataProvider: DataProvider = {
  getList: async ({ resource }) => {
    const endpoint = generateEndpoint(resource, 'getList');
    const response = await fetch(endpoint);
    const data = await response.json();
    return { data };
  },
  create: async ({ resource, parameters }) => {
    const endpoint = generateEndpoint(resource, 'create');
    const response = await fetch(endpoint, {
      method: 'POST',
      body: JSON.stringify(parameters),
      headers: {
        'Content-Type': 'application/json'
      }
    });
    const data = await response.json();
    return { data };
  },
  // other methods...
};

function generateEndpoint(resource: string, action: string): string {
  // Define your custom logic to generate the endpoint URL based on the resource and action
  // For example:
  switch (action) {
    case 'getList':
      return `<https://example.com/api/v1/gw/${resource}/fetch`;>
    case 'create':
      return `<https://example.com/api/v1/gw/${resource}/create`;>
    // other cases...
    default:
      return `<https://example.com/api/v1/${resource}`;>
  }
}

const myDataProvider: DataProvider = {
  getList: async ({ resource }) => {
    const endpoint = generateEndpoint(resource, 'getList');
    const response = await fetch(endpoint);
    const data = await response.json();
    return { data };
  },
  create: async ({ resource, parameters }) => {
    const endpoint = generateEndpoint(resource, 'create');
    const response = await fetch(endpoint, {
      method: 'POST',
      body: JSON.stringify(parameters),
      headers: {
        'Content-Type': 'application/json'
      }
    });
    const data = await response.json();
    return { data };
  },
  // other methods...
};

function generateEndpoint(resource: string, action: string): string {
  // Define your custom logic to generate the endpoint URL based on the resource and action
  // For example:
  switch (action) {
    case 'getList':
      return `<https://example.com/api/v1/gw/${resource}/fetch`;>
    case 'create':
      return `<https://example.com/api/v1/gw/${resource}/create`;>
    // other cases...
    default:
      return `<https://example.com/api/v1/${resource}`;>
  }
}

In this example, the generateEndpoint function is used to dynamically generate the endpoint URL based on the resource and action type. You can customize this function to suit your specific needs. Remember to replace <https://example.com/api/v1/> with your actual API base URL. For more information, refer to the Data Provider documentation (https://refine.dev/docs/guides-concepts/general-concepts/#data-provider). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai so what would my resource data look like in this case

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In your case, since the API endpoint routes can take any form, you might want to define your resources with additional metadata to specify the different endpoint paths for different operations. Here's an example of how you might define your resources:

{
  name: 'campaign',
  list: '/gw/campaign/fetch',
  create: '/gw/campaign/create',
  // other endpoints...
}

{
  name: 'campaign',
  list: '/gw/campaign/fetch',
  create: '/gw/campaign/create',
  // other endpoints...
}

In this example, the list and create properties are used to specify the endpoint paths for the getList and create operations respectively. You can add more properties as needed for other operations. Then, in your dataProvider, you can use these properties to generate the endpoint URL:

const myDataProvider: DataProvider = {
  getList: async ({ resource }) => {
    const endpoint = `<https://example.com/api/v1${resource.list}`;>
    const response = await fetch(endpoint);
    const data = await response.json();
    return { data };
  },
  create: async ({ resource, parameters }) => {
    const endpoint = `<https://example.com/api/v1${resource.create}`;>
    const response = await fetch(endpoint, {
      method: 'POST',
      body: JSON.stringify(parameters),
      headers: {
        'Content-Type': 'application/json'
      }
    });
    const data = await response.json();
    return { data };
  },
  // other methods...
};

const myDataProvider: DataProvider = {
  getList: async ({ resource }) => {
    const endpoint = `<https://example.com/api/v1${resource.list}`;>
    const response = await fetch(endpoint);
    const data = await response.json();
    return { data };
  },
  create: async ({ resource, parameters }) => {
    const endpoint = `<https://example.com/api/v1${resource.create}`;>
    const response = await fetch(endpoint, {
      method: 'POST',
      body: JSON.stringify(parameters),
      headers: {
        'Content-Type': 'application/json'
      }
    });
    const data = await response.json();
    return { data };
  },
  // other methods...
};

In this example, resource.list and resource.create are used to get the endpoint paths for the getList and create operations respectively. Remember to replace <https://example.com/api/v1> with your actual API base URL.

@kapa.ai In a resource called campaigns, the list endpoint route can be /gw/campaign/fetch while the create endpoint can be /gw/campaign/create. And in another resource called dashboard, the list route being /gw/dashboard/all/fetch amd the create endpoint route being /gw/dashboard/all/data/create. How can I make this work?

@kapa.ai im going to have multiple endpoints. SO will i be writing switch cases for all of them?

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you have a large number of resources and endpoints, writing switch cases for all of them might not be the most efficient solution. Instead, you can define your resources with additional metadata to specify the different endpoint paths for different operations. Here's an example of how you might define your resources:

const resources = [
  {
    name: 'campaign',
    endpoints: {
      getList: '/gw/campaign/fetch',
      create: '/gw/campaign/create',
      // other endpoints...
    }
  },
  {
    name: 'dashboard',
    endpoints: {
      getList: '/gw/dashboard/all/fetch',
      create: '/gw/dashboard/all/data/create',
      // other endpoints...
    }
  },
  // other resources...
];

const resources = [
  {
    name: 'campaign',
    endpoints: {
      getList: '/gw/campaign/fetch',
      create: '/gw/campaign/create',
      // other endpoints...
    }
  },
  {
    name: 'dashboard',
    endpoints: {
      getList: '/gw/dashboard/all/fetch',
      create: '/gw/dashboard/all/data/create',
      // other endpoints...
    }
  },
  // other resources...
];

In this example, the endpoints property is an object that maps action types to endpoint paths. You can add more properties as needed for other operations. Then, in your dataProvider, you can use these properties to generate the endpoint URL:

const myDataProvider: DataProvider = {
  getList: async ({ resource }) => {
    const resourceConfig = resources.find(r => r.name === resource);
    const endpoint = `<https://example.com/api/v1${resourceConfig.endpoints.getList}`;>
    const response = await fetch(endpoint);
    const data = await response.json();
    return { data };
  },
  create: async ({ resource, parameters }) => {
    const resourceConfig = resources.find(r => r.name === resource);
    const endpoint = `<https://example.com/api/v1${resourceConfig.endpoints.create}`;>
    const response = await fetch(endpoint, {
      method: 'POST',
      body: JSON.stringify(parameters),
      headers: {
        'Content-Type': 'application/json'
      }
    });
    const data = await response.json();
    return { data };
  },
  // other methods...
};

const myDataProvider: DataProvider = {
  getList: async ({ resource }) => {
    const resourceConfig = resources.find(r => r.name === resource);
    const endpoint = `<https://example.com/api/v1${resourceConfig.endpoints.getList}`;>
    const response = await fetch(endpoint);
    const data = await response.json();
    return { data };
  },
  create: async ({ resource, parameters }) => {
    const resourceConfig = resources.find(r => r.name === resource);
    const endpoint = `<https://example.com/api/v1${resourceConfig.endpoints.create}`;>
    const response = await fetch(endpoint, {
      method: 'POST',
      body: JSON.stringify(parameters),
      headers: {
        'Content-Type': 'application/json'
      }
    });
    const data = await response.json();
    return { data };
  },
  // other methods...
};

In this example, resourceConfig.endpoints.getList and resourceConfig.endpoints.create are used to get the endpoint paths for the getList and create operations respectively. Remember to replace <https://example.com/api/v1> with your actual API base URL.
