Continuous Integration for React Native

#Continuousintegration & #reactnative. Match made in heaven!

  • This guide is for you if… – – We will show you how to setup Continuous Integration for React Native builds in just a few clicks using Nevercode.
  • When the scanning completes you’ll be presented with three options: – – The Project selection here means a directory in your repository where your React Native configuration file is stored.
  • Nevercode installs the dependencies listed out in your project’s file automatically using Yarn package manager right after your repository is cloned for building.
  • Signing React Native applications in Nevercode is done just like it is with native Android and iOS applications.
  • With support for React Native, iOS, Android, Cordova and Ionic, Nevercode is truly a mobile developer’s choice to release defect-free mobile apps faster.

One tool to build them all

React & Redux – Internationalisation by dbushell #javascript #reactjs #redux via JavaScriptKicks

  • Even if you only support one language the technique below allows text to be edited without re-transpiling the React source.
  • I start by adding two properties to my Redux state: – – The property is the translation key to be used.
  • The property maps these keys to text strings for each component name.
  • To continue the example, I start with this basic component: – – All the text is hard-coded and the property is inflexible.
  • Not all components need to be connected to the Redux state directly.

  • This package polyfills components so that the new and lifecycles will also work with older versions of React (0.14.9+).

Making of a component library for React – Hacker Noon

Making of a component library for React  #reactjs

  • For this library, this is what I had at the end: – assets/ — Skip this folder, this is just for images I had in API docsbuild/ — UMD and ES module build files + sourcemaps.examples/ — This folder contains test .
  • PopupMenu header partAs we build components for UI we include style files, rollup allows us to make bundles with styles and images the same way as webpack does.
  • import React, {Component} from ‘react’;In my case I even need to use React to provide context to child components this old way: (old because recently React introduced new Context API).
  • I have PopupTable that takes popupWidth of the parent PopupMenu – React context in PopupMenu classI would like to also highlight classnames npm module that does pretty good job in combining multiple classes from CSS modules: – classnames module exampleUsage: – Unit testingFirst you need to decide which unit-testing framework you…

Choosing Between React and Vue For WordPress Development

Choosing Between #ReactJS and #VueJS For WordPress Development -

  • In React, component state is mutated using the function setState(), while in Vue, you just change the variable value directly or you use v-model directive in an HTML template and it’s all magical.
  • Any mildly complex Vue or React app needs state management — using Redux, V\uex or similar — for app state and that involves state update function.
  • When creating React or Vue components this way, you have to write your own change handlers to modify state.
  • Vue’s data model is inspired by React and other frameworks based on observables.
  • In the React world create-react-app is a CLI tool, like Vue CLI for scaffolding apps.

How to make Jenkins build NodeJS, Ruby, and Maven on Docker

How To Make Jenkins Build #NodeJS, #Ruby, And #Maven On #Docker  #reactjs #devops

  • Jenkins can speed up repetitive tasks that robots are much better performing and Docker simplifies spinning up VM’s for your application in a very simple and repeatable way.
  • What I’m going to cover here is how to setup your Jenkins server in a Docker container and how to fix some of the limits of the Jenkins official image.
  • While it is nice of Jenkins to offer an official docker image, you’ll quickly run into a few issues if you are doing anything even slightly other than compiling plain Java.
  • For instance, Maven, the popular dependency management tool for Java, is not included in the Docker container.
  • You’ve learned to create a Jenkins Docker-container that’s ready to run jobs for Java, Ruby and NodeJS projects.

Setup your Jenkins server in a Docker container and fix some of the limits of the official image I discovered so you can get up and building faster.
