Now, it’s actually starting to get fun because now we see different stuff happening here, things are displaying on the screen. For that one, the font size is going to be a variable font small. Just to place it on top, I set the max with the 700 pixels on this text position is going to be absolute. So I set an animation that are going to call animate hero image, and is going to be for one second. And you can see that we actually had the image here but we haven’t set any other properties.
- So that’s the property that we’re going to write to the session storage.
- And you can see here that are sending the callback, that’s the function that I have in the app component here.
- All right, so that’s the old movies that we already have in the state, then I have a coma.
But if we named this file, for example, test component, also, we have to specify it like this. And this is great when you import stuff as I’m going to show you later. So therefore, I also think it’s nice to have everything related to component in its own folder.
Build a meme generator
I don’t think I ever will use them again, actually, because I love hooks. And then I’m going to show you how to https://remotemode.net/become-a-front-end-developer/react-by-example/ convert this application into TypeScript. And you can do this every time you change something on your site.
And up here where we import the thumb, we also got to import our rate component, dot dot forward slash rate. And the first thing we do in this component is to create a state with a value and set value equals use state And we’re going to start with the value five, the rating is going to be between one and 10. And inside of that folder, we create a new file that’s called index dot j s and I actually not going to have any styling for this one. Alright, const user, we’re going to grab the user from the context, we don’t need to set anything here, we just need the user. From dot dot forward slash and dot dot forward slash, again, we have the context file like this. Now we have the input, we nest, this one inside of the wrapper component, we set the width to 100%.
It’s time to learn modern React (with Hooks) the right way
And these values are auto generated from somewhere on the internet, I usually do that when I create gradients, it’s so easy to just go there and type in your gradient and it will give you the code. And also we’re going to create if you look here at the finished application. And in our case, we want to set a background image, the usual way you did that back in the days was that you had to create some inline CSS when you had a dynamic image. So there’s probably been a lot of things you can optimize in this application. And this one I have to construct because the image URL is constructed by the image base URL that we that we get here, and also the backdrop size. And we also need to check that we actually have any movies in the state.
- And that’s our CSS variables that we’re going to use for this application.
- So they tell you here to run type checking on the props for a component, you can assign a special prop types property.
- So go back to the home dot j s, and we import curly brackets, we’re going to import the poster underscore size, all capital letters, we’re going to import the backdrop, underscore size.
That’s how you utilize the session storage to persist the state in your application. To mark market with helpers, an import is persisted state from dot dot forward slash help us. Just as before, we create a const that we call session state equals. And if we reload the page, it works, it grabs from the session storage all the time. And this is all that we need to retrieve something from the session state, we make sure that we don’t check the session storage if we’re in a search.
We’re going to call this handleToggleTodo and create it within our TodoList component. In this case, our function that we use to handle the event doesn’t have to receive any event data. Just like our state, we can work with refs by calling the appropriate React hook. To create a ref, we just need to call React.useRef() at the top of AddTodo. We don’t have to pass it an initial value, but we can give it a default value if we needed to.
