Flexible, typed and easy to use React Component ⚛ to provide CSV, TSV and other delimiter-separated values formats (DSV) import functionality.
Add the package with the package manager of choice to your project:
- yarn:
yarn add react-dsv-import - npm:
npm install react-dsv-import - npx:
npx -p react-dsv-import
import { DSVImport, ColumnsType } from 'react-dsv-import';
type BasicType = { forename: string; surname: string; email: string };
const columns: ColumnsType<BasicType> = [
{ key: 'forename', label: 'Forename' },
{ key: 'surname', label: 'Surname' },
{ key: 'email', label: 'Email' }
];
<DSVImport<BasicType> columns={columns}>
<DSVImport.TextareaInput />
<DSVImport.TablePreview />
</DSVImport>
import { DSVImport } from 'react-dsv-import';
const columns = [
{ key: 'forename', label: 'Forename' },
{ key: 'surname', label: 'Surname' },
{ key: 'email', label: 'Email' }
];
<DSVImport columns={columns}>
<DSVImport.TextareaInput />
<DSVImport.TablePreview />
</DSVImport>
