CSV Import
You can easily import CSV files for any resource by using refine's customizable useImport hook, optionally with <ImportButton> component. useImport hook returns the necessary props for <ImportButton> component.
Internally, useImport uses Papa Parse to parse the CSV file contents.
Usage​
We'll use the useImport hook and add the <ImportButton> with properties returned from useImport. When the button gets triggered, it creates the imported resources using create or createMany dataProvider methods under the hood.
import { List, useImport, ImportButton } from "@refinedev/antd";
export const PostList: React.FC = () => {
const importProps = useImport<IPostFile>();
return (
<List
headerProps={{
extra: <ImportButton {...importProps} />,
}}
>
...
</List>
);
};
interface IPostFile {
id: number;
title: string;
content: string;
userId: number;
categoryId: number;
status: "published" | "draft" | "rejected";
}
interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: { id: number };
user: { id: number };
}
As an example, let's say we have a CSV file like this:
"title","content","status","categoryId","userId"
"dummy title 1","dummy content 1","rejected","3","8"
"dummy title 2","dummy content 2","draft","44","8"
"dummy title 3","cummy content 3","published","41","10"
We need to map the CSV data to the API's data. In our case, we have a categoryId and userId in CSV. For the API, we need to send the category and user objects. To do this, we'll use the mapData prop of useImport hook.
import { List, useImport, ImportButton } from "@refinedev/antd";
export const PostList: React.FC = () => {
const importProps = useImport<IPostFile>({
mapData: (item) => {
return {
title: item.title,
content: item.content,
status: item.status,
category: {
id: item.categoryId,
},
user: {
id: item.userId,
},
};
},
});
return (
<List
headerProps={{
extra: <ImportButton {...importProps} />,
}}
>
...
</List>
);
};
interface IPostFile {
id: number;
title: string;
content: string;
userId: number;
categoryId: number;
status: "published" | "draft" | "rejected";
}
interface IPost {
id: number;
title: string;
content: string;
status: "published" | "draft" | "rejected";
category: { id: number };
user: { id: number };
}
And it's done. When you click on the button and provide a CSV file of the headers "title","content","status","categoryId" and "userId", it should be mapped and imported. Mapped data is the request payload. Either as part of an array or by itself as part of every request. In our example, it fires POST request/requests like this:
{
"title": "dummy title 1",
"content": "dummy content 1",
"status": "rejected",
"category": {
"id": "3"
},
"user": {
"id": "8"
}
}
Depending on the batchSize option, posts can get sent one by one or as batches. By default, all records are sent in one createMany call.
