I have tried modify the babel but i'm really dont know what is happening

Next im going to put the ponent, actions and reducers

AddVehicle:

import React, { Component } from "react";
import { connect } from "react-redux";
import { Link } from "react-router-dom";
import * as vehiclesActions from '../../actions/vehiclesActions'

class AddVehicle extends Component {

    changingName = (event) => {
        this.props.changeName(event.target.value);
    }

    changingModel = (event) => {
        this.props.changeModel(event.target.value);
    }

    changingBrand = (event) => {
        this.props.changeBrand(event.target.value);
    }

    changingLicenseplate = (event) => {
        this.props.changeLicenseplate(event.target.value);
    }

    saving = (event) => {
        event.preventDefault();
        const { name, model, brand, licenseplate } = this.props.vehicle;
        const newVehicle = {
            name: name,
            model: model,
            brand: brand,
            licenseplate: licenseplate
        }
        this.props.uploadingData(newVehicle)
    }


    render() {
        console.log(this.props.vehicle.name)

  • Thank you @P Walker, adding the options:... below the 'babel-loader' worked also for me. However, I needed to call a npm install --save-dev @babel/plugin-transform-runtimefirst, since the plugin was not installed. – Ernst Plesiutschnig Commented Dec 5, 2020 at 19:16

Reset to default 10

I had this issue as well when I updated a class's method to include async/await in my React app. The solution I found (inspired by https://stephencharlesweiss./regenerator-runtime-not-defined/) was to import the @babel/plugin-transform-runtime NPM package and reference that in my Webpack file as a plugin via plugins: ['@babel/plugin-transform-runtime']. With this approach, I did not have to use an import statement for regeneratorRuntime as I've seen others do to get around this issue. Here's a snippet from my Webpack file:

module.exports = options => {
    return {
        module: {
            rules: [
                // React App Setup
                {
                    test: /.(js|jsx)$/,
                    exclude: /node_modules/,
                    use: [{
                        loader: 'babel-loader',
                        options: {
                            cacheDirectory: true,
                            plugins: ['@babel/plugin-transform-runtime']
                        }
                    }]
                },
                ...
