The second argument of ‘connect’ function are action creators (in our case ‘fetchNotes’ action) that can be invoked via props object of our component. The result of ‘mapStateToProps’, a plain object, will be merged to component props. That means any time store is updated, ‘mapStoreToProps’ will be called. By ‘mapStoreToProps’ we are subscribed to Redux store updates. On the bottom of component, we can find ‘connect’ wrapper function that is responsible for connecting a React component to a Redux store. Method ‘renderEmptyListMessage’ displays a message in a case when there is no notes available. ‘Link’ component is used for creating a link to appropriate endpoint by using React Router.

Method ‘renderList’ displays a list of messages, by going through all notes and by rendering appropriate list content with note data. Inside of this method we are invoking appropriate methods for displaying a list of notes in case where there are notes available (method ‘renderList’) or appropriate message, in case when notes list is empty (method ‘renderEmptyListMessage’). Method ‘render’ is class-based component method for rendering a content. The lifecyle method ‘componentDidMount’ runs after the component output has been rendered to the DOM. NotesList is a class component and it loads data via ‘’ method called inside of ‘componentDidMount’ lifecycle method. The second component that we are going to create is ‘Header’ component, which is functional component (since it’s not class and doesn’t extends from ‘React.Component’). The main difference between functional and class components is that you can’t use state and lifecycle hooks in functional components.

Class - a class that requires you to extend from React.Component and to create a ‘render’ method in order to return React element.

Functional - it’s just a function that accepts props and returns React element.

Some ‘Route’ components have ‘exact’ property and this is used in order not to invoke similar ‘Route’ with very similar location attribute.īefore we start writing our own components, let us remind ourselves which types of components exist in React apps: The ‘Switch’ is used for rendering the first ‘Route’ that matches it’s location attribute. it will be responsible for rendering different components (like ‘NoteCreate’ component, when user navigates to the ‘/note/new’ url).Īs we can see in App component, we are rendering ‘Header’ component and afterwards different components based on current url. It also contains React Router, the component that will allow us to navigate to different ‘pages’, i.e. We are going to create all those components later in this article. In generated index.html (located inside of ‘public’ folder’) please add link to bootstrap.css file inside of ‘head’ tag:ĭon’t be afraid of a lot of import statements, on the top of this class.

We’ll put our classes there, so we don’t need pregenerated ones. Let’s start!įirstly, we are going to initialize React project by invoking the following npm command: npx create-react-app react_redux_form_sampleĪnd from ‘src’ folder remove all the files.

(Don’t worry, you have to do only few steps in order to make it work 😃)Īt the end of this article you can find source code of React application that we are going to build in this article.

#Noteapp with github backend download#

In order to start backend app please download it’s source code and check it’s README.md: In this article we are going to build simple Notes App that will use NestJS backend. It’s component based and it uses XML-like syntax called JSX.

It allows us to create reactive interfaces very easily because it can listen for state change and when state change occurs, it will update UI layout. React is a JavaScript library for building user interfaces.

You can check this guide if you use a Windows machine, Installing MongoDB on Windows.įor Linux users, follow this tutorial, How to Install MongoDB on Ubuntu 20.04.Before we start with the coding, let us remind ourselves what is React. You may download and install the MongoDB database server from the official MongoDB website. Go to the official website to download Python 3. To follow this article along it is important to have the following:

Create CRUD features in Django REST API.

Learn how to set up and run Django REST API.

Understand to integrate MongoDB into Django projects.

You will learn how to build CRUD features in a notes app. You will learn how to use the powerful Django REST framework and MongoDB in your web projects. Django is one of the most well-liked packages that Python developers use to build websites. The Django REST framework is a robust package of tools for building extensible APIs. It keeps data in JSON-like format instead of the traditional row-column format.
