  • We’ll be taking a closer look at the instructor side of things, implementing the container pattern to build of the ability for an instructor to select a calendar day and a student to view that student’s attendance record details for that day.
  • So, we’ll build a container components, , that contains the child presentational components of calendar and attendance record show.
  • So, let’s teach how to identify and grab the attendance record for the selected student and day, and pass that down to the appropriate presentational components.
  • So, we’ll build another container component, , that will fetch the student data and pass it down to a presentational component, as part of – – should follow a similar pattern to ––use to grab the students and use the lifecycle method to fetch students from the API if none…

  • What React excels at is letting us compose a UI by composing custom components.Custom componentsThere are 2 ways to define a component in React:A stateless component does not manage internal state, and is just a function:const BlogPostExcerpt = () = { return ( div h1Title/h1 pDescription/p /div ) }A stateful…
  • In a stateless component, props is all that gets passed, and they are available by adding props as the function argument:const BlogPostExcerpt = (props) = { return ( div h1{props.title}/h1 p{props.description}/p /div ) }In a stateful component, props are passed by default.
  • There is no need to add anything special, and they are accessible as this.props in a Component instance.import React, { Component } from ‘react’ class BlogPostExcerpt extends Component { render() { return ( div h1{this.props.title}/h1 p{this.props.description}/p /div ) } }PropTypesSince JavaScript is a dynamically typed language, we don’t really have…
  • Even before running the code, our tools (editors, linters) can detect when we are passing the wrong values:import PropTypes from ‘prop-types’; import React from ‘react’ class BlogPostExcerpt extends Component { render() { return ( div h1{this.props.title}/h1 p{this.props.description}/p /div ) } } BlogPostExcerpt.propTypes = { title: PropTypes.string, description: PropTypes.string }; export…
  • So if you need to manage state in a stateless (function-based) Component, you first need to “upgrade” it to a Class component:const BlogPostExcerpt = () = { return ( div h1Title/h1 pDescription/p /div )}becomes:import React, { Component } from ‘react’ class BlogPostExcerpt extends Component { render() { return ( div…

  • In the code above I’ve used the class, but we could just as easily write something like this: – – So, we’ve stored the state of our button in two places.
  • For a larger project, we want to separate our component’s state from the DOM.
  • Why would we want to do that our component’s state from its DOM representation?
  • In the example above, our toggle button state happens to control two things in the DOM.
  • Still, this code doesn’t store our state in the DOM.

  • The above command created an empty React Native project that you can immediately run on your device using the or commands (you need to have an Android emulator already started for the last command to work).
  • Just like in React, a React Native app is made up by several components that work together to achieve the ultimate goal of the app.
  • You can read more about this topic here: – – Start by creating a constructor for our component that sets the initial state: – – In the method, change the state to contain the newly generated number: – – Finally add a new component in the method that will show…
  • Import the component then add it to the app: – – We need to show the current slider value to the user so we will add it to the state of our app: – – When the slider moves, we have to update the state: – – Add a new…
  • First, let’s fix one small problem: if you rotate your emulator screen (Cmd+Left or Right Arrow) you will see that the app will go into landscape and it will not be usable anymore 🙁 – – Too lock the app to portrait we need to go “native”.
