Detailed description of the server rendering Transformation (koa2 + webpack3.11) and koa2webpack3.11 of the React Project
Because of the need for Web SEO, we need to transform the previous React project into server rendering. After some investigation and research, we have consulted a lot of Internet information. Step into the trap.
Selection idea: Implement server rendering. If you want to use the latest
, with more traditional JavaScript MVC frameworks such as backbone.js, we have done many adventures and attempts in this direction.Most hybrid applications start with a fast, responsive user interface. After that, it was easy to hit the south wall. This usually occurs at the end of the project, where, after several weeks of effort, the project has added a lot of functionality, and the content in the DOM is becoming richer.At this point, the relationship between the view
1. Problems encountered at workWe in the use of react-native must have encountered a variety of wonderful problems, such as the introduction of echarts time inexplicable error, but Echarts official website obviously tell us can lazy loading, this is because basically JS most native component library does not support react-native, Direct quoting will be reported"undefined is not an object (evaluating ‘ua.mat
The recent period has been a very exciting time for front-end engineers, as the three web frameworks are releasing new versions, giving us a glimpse of a more powerful web framework. Ember2.0 was released 2 months ago, and upgrading from 1.0 to 2.0 is very simple. A few weeks ago, react released version 0.14. There are also many popular front-end frameworks, like backbone, knockout and Aurelia. If you want to develop a web app, it is recommended to us
React has become a complete set of back-and-forth Web APP solutions. The derivative React Native project, the goal is magnificent, wants to write the Web app the way to write Native app. If it does, the entire Internet industry will be subverted, because the same group of people will be able to run the server, the browser and the phone at the same time with only one UI to write.Since
will make a concise statement in the relevant places.
The first step: dividing the UI ComponentReact is all about modular, composable components.
The react is modular and component-structured. Our first step here is to divide the application into components. I circled the various components we were about to implement
NODEJS environment.React several major mechanisms:
Component ofReact advocates the development of a front-end UI with component thinking, by splitting the parts of the UI into components and assembling them when they are used, so that a single function is clear and more conducive to code reuse and later maintenance.
Virtual DOMTo achieve high performance and cross-platform features for Dom control, r
The text component is a basic component in react, similar to the TextView component in Android, to display basic text information, which, in addition to the basic display layout, can be nested, set styles, and can do events (for example, click) processing. Let's take an example:1 ImportReact, {Component} from ' React ';2 Import {3 Appregistry,4 StyleSheet,5 Text6} from '
Premise: A small web front end, completely not Android with iOS development, first contact, there are a lot of questions that do not understand. Please forgive me.Environment: Win7Results:First, the SDK installationHint: The installation must pass the agent, otherwise will be very slow yo ~ ~Install version 2.0 of Android Studio installationInstall the following SDK in studioAdd an environment variable (the variable value is the SDK path):Second, global reac

Super simple! Now you can go to Santorini...
Step 2: Install dependency
If your editor is not configured, it may be painful to migrate from Angular to React. We will first install linting.
npm install --save eslint babel-eslint
Next, install react2angular. If you have never installed React, you will also need to install react,
With the fire of react, the flux architecture followed fire, Redux was the leader in the library of flux architecture, and more and more developers used React+redux to develop applications.
Indeed, REACT+REDUX+WEBPACK+BABEL+ES6, this is a highly productive combination.
The one-way flow from the flux architecture makes the logic and data flow of applications cont
My own understanding redux is similar to the Vuex in Vue, is a data manager, say, we start from the classic counter case to explain
Implementing counters using Redux
Create the following react project, I used to put each module block, only so many files, of course you can also write in a JS file, this is not the focus
First, let's look at the entry file for the project Index.js
Import ' Core-js/fn/object/assign '; import
().child(‘users‘).push({
username: name,
email: email
}); this.updateMe("Yoona", "[emailprotected]", ref.key);
} // calling this.appendOneMoreUser("Yuri", ‘[emailprotected]‘, null);
So under "Users" node, we want to append one new node, the UID would be generated randomly.
The "ref" object contains "key" prop which ref to the UID in the database.
Update one node:update ()
updateMe(name, email, key){ const update
React-router provides, props for setting a specific style on a Link component whose path matches our current route. Activestyle allows for a inline style while activeclassname allows for a class defined in an external stylesheet.const Links = () =nav> LinkActivestyle={{color:' Green '} to="/">HomeLink> LinkActivestyle={{color:' Green '} to= "/about">AboutLink> LinkActiveclassname= "Active" to= "/contact">ContactLink> nav>;.

React ' s abstraction over the DOM means that it's not always obvious how does dom-related things, like working with the HT ML Canvas API.When working with HTML Canvas, HiDPI displays like Apple's Retina display require a bit of extra coaxing, to make sure the Y look crisp and sharp. This lesson covers how to write a method that automatically scales we component for the user ' s displays.Happily, once it ' s written, you can forget all about the DPI o
API supports the iOS platform, and we need to use elevation to set shadows under the Android platform. Watch for API Doc's Android or iOS logo
Not all react native some of the APIs or components of some of the properties and methods are compatible with Android and iOS, in react native API Doc typically identifies the platform supported by the property or method
first, so let's look at it. Naturally, whether you are learning React or not, you can understand some programming ideas. For beginners at the front end, there will be a certain learning cost. I believe that reading from the very beginning can continue.
If you need a project that can run well, you will be exposed to babel, webpack, eslint, karma, and other tools. This is a nightmare for beginners. I do not recommend that you stick it in this vortex. T

Webpack+react+typescript Development Environment
Webpack
A front-end packaging tool developed by Facebook's Instagram team, Webpack is based on dependency for code integration than some of the front-end automated building tools such as Gulp and grunt. That is, there must be a portal file, which will introduce other script files, then webpack all the files through these dependencies, and automatically generate sourcemap to facilitate debugging.
