Webpack 2

Aquí veremos un pequeño ejemplo de como usar webpack2 + babel + sass

instalar dependencias

instalamos dependencias básicas

npm install [email protected] babel-core babel-preset-es2015 node-sass --save-dev

bash git pull each dir

Execute command:

git_current_branch () {
  #https://stackoverflow.com/a/35298459
  echo $(git branch | grep '^*' | sed 's/* //' )
}

Test promise

describe('unittest', () => {
    test('the data is peanut butter', () => {
        function fetchData(){
            return new Promise((resolve,reject)=>{
                resolve('peanut butter');
            });
        }
 expect.assertions(1);

task:

const fs = require('fs');
const param = process.env.page;
const webpackFile = './webpack.config.js';

const msgErr = (msg)=>{
	console.log(msg);
	process.exit();
}

Redux es un almacenador de estados

con redux nuestra aplicación puede trabajar con estados en un solo arbol de datos. Redux trabaja con unos cuantos métodos pero efectivos los cuales son

createStore
dispatch
getState
subscribe

un ejemplo básico:

regex valid js update 2021

const validEmail(str) => !/(\.{2}|-{2}|_{2})/.test(str) && /^[a-z0-9][a-z0-9-_\.]+@([a-z]|[a-z0-9]?[a-z0-9-]+[a-z0-9])\.[a-z0-9]{2,10}(?:\.[a-z]{2,10})?$/.test(str);

validEmail('[email protected]'); //true
validEmail('[email protected]'); //true
validEmail('[email protected]'); //true
validEmail('[email protected]'); // true (short domain)
validEmail('[email protected]'); // true (short domain)
