You can install the package via npm or yarn:

# npm
npm install vue-csv-import

# Yarn
yarn add vue-csv-import

You can import components individually.

import {VueCsvToggleHeaders, VueCsvSubmit, VueCsvMap, VueCsvInput, VueCsvErrors, VueCsvImport} from 'vue-csv-import';

Or import all as a plugin.

import {createApp} from "vue";
import App from "./App.vue";
import {VueCsvImportPlugin} from "vue-csv-import";

createApp(App)
    .use(VueCsvImportPlugin)
    .mount("#app");

A minimal working example with all components will look something like this:

<template>
    <vue-csv-import
        v-model="csv"
        :fields="{name: {required: false, label: 'Name'}, age: {required: true, label: 'Age'}}"
    >
        <vue-csv-toggle-headers></vue-csv-toggle-headers>
        <vue-csv-errors></vue-csv-errors>
        <vue-csv-input></vue-csv-input>
        <vue-csv-map></vue-csv-map>
