Uploading a file to an api endpoint

Can you provide a simple example of a component that would upload a file to an api endpoint using the ant design Upload component?

Hi @HypnoticMeat. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Sure! Here is a simple example of a component that uploads a file to an API endpoint using the Ant Design Upload component. This example uses the useApiUrl hook from Refine to get the API URL and the Upload.Dragger component from Ant Design for the file upload interface.

import { useApiUrl } from "@refinedev/core";
import { getValueFromEvent, Create, useForm } from "@refinedev/antd";
import { Upload, Form, Input } from "antd";

export const PostCreate: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<IPost>();
  const apiUrl = useApiUrl();

  return (
    <Create saveButtonProps={saveButtonProps}>
      <Form {...formProps} layout="vertical">
        <Form.Item
          label="Title"
          name="title"
          rules={[
            {
              required: true,
            },
          ]}
        >
          <Input />
        </Form.Item>
        <Form.Item label="Image">
          <Form.Item
            name="image"
            valuePropName="fileList"
            getValueFromEvent={getValueFromEvent}
            noStyle
          >
            <Upload.Dragger
              name="file"
              action={`${apiUrl}/media/upload`}
              listType="picture"
              maxCount={5}
              multiple
            >
              <p className="ant-upload-text">Drag & drop a file in this area</p>
            </Upload.Dragger>
          </Form.Item>
        </Form.Item>
      </Form>
    </Create>
  );
};

interface IPost {
  id: number;
  title: string;
  image: [
    {
      uid: string;
      name: string;
      url: string;
      status: "error" | "success" | "done" | "uploading" | "removed";
    },
  ];
}

import { useApiUrl } from "@refinedev/core";
import { getValueFromEvent, Create, useForm } from "@refinedev/antd";
import { Upload, Form, Input } from "antd";

export const PostCreate: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<IPost>();
  const apiUrl = useApiUrl();

  return (
    <Create saveButtonProps={saveButtonProps}>
      <Form {...formProps} layout="vertical">
        <Form.Item
          label="Title"
          name="title"
          rules={[
            {
              required: true,
            },
          ]}
        >
          <Input />
        </Form.Item>
        <Form.Item label="Image">
          <Form.Item
            name="image"
            valuePropName="fileList"
            getValueFromEvent={getValueFromEvent}
            noStyle
          >
            <Upload.Dragger
              name="file"
              action={`${apiUrl}/media/upload`}
              listType="picture"
              maxCount={5}
              multiple
            >
              <p className="ant-upload-text">Drag & drop a file in this area</p>
            </Upload.Dragger>
          </Form.Item>
        </Form.Item>
      </Form>
    </Create>
  );
};

interface IPost {
  id: number;
  title: string;
  image: [
    {
      uid: string;
      name: string;
      url: string;
      status: "error" | "success" | "done" | "uploading" | "removed";
    },
  ];
}

In this example: - The useApiUrl hook is used to get the base URL of the API. - The Upload.Dragger component is used to create a drag-and-drop area for file uploads. - The action prop of the Upload.Dragger component is set to the API endpoint for file uploads. - The getValueFromEvent method is used to convert the uploaded files to the Ant Design UploadFile object. For more details, you can refer to the Multipart Upload documentation (https://refine.dev/docs/advanced-tutorials/upload/multipart-upload/#create-form). This should give you a good starting point for uploading files to an API endpoint using Ant Design's Upload component in a Refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can you expand on this to also provide a means of downloading a file from the backend using the api endpoint of ${apiUrl}/media/download/{fileId}, then opening it in a new window

Let me check the knowledge base for you. One moment! :books: ---------------------- Sure! Here is an expanded example that includes both uploading a file to an API endpoint and downloading a file from the backend using the API endpoint ${apiUrl}/media/download/{fileId}. The download functionality will open the file in a new window.

import { useApiUrl } from "@refinedev/core";
import { getValueFromEvent, Create, useForm } from "@refinedev/antd";
import { Upload, Form, Input, Button } from "antd";
import { useState } from "react";

export const PostCreate: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<IPost>();
  const apiUrl = useApiUrl();
  const [fileId, setFileId] = useState<string | null>(null);

  const handleDownload = () => {
    if (fileId) {
      window.open(`${apiUrl}/media/download/${fileId}`, "_blank");
    }
  };

                  // Assuming the response contains the file ID
                  setFileId(info.file.response.id);
                }
              }}
            >
              <p className="ant-upload-text">Drag & drop a file in this area</p>
            </Upload.Dragger>
          </Form.Item>
        </Form.Item>
        {fileId && (
          <Button type="primary" onClick={handleDownload}>
            Download File
          </Button>

      </Form>
    </Create>
  );
};

interface IPost {
  id: number;
  title: string;
  image: [
    {
      uid: string;
      name: string;
      url: string;
      status: "error" | "success" | "done" | "uploading" | "removed";
    },
  ];
}

In this expanded example: - A useState hook is used to keep track of the uploaded file's ID. - The onChange event of the Upload.Dragger component is used to set the file ID when the upload is complete. - A Button component is added to trigger the download of the file. When clicked, it opens the file in a new window using the window.open method. For more details, you can refer to the Multipart Upload documentation (https://refine.dev/docs/advanced-tutorials/upload/multipart-upload/#create-form). This should provide a complete solution for both uploading and downloading files using Ant Design's Upload component in a Refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can you expand on the download portion to grab the filename and content type of the download when displaying in the new window?

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To expand on the download portion to grab the filename and content type of the download when displaying it in a new window, you can make an API call to fetch the file metadata before opening the file. Here is an updated example that includes this functionality:
