Builds the app for production to the folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

Note: this is a one-way operation. Once you , you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use . The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

Create a meme generator by using ReactJS

In this tutorial, we’ll make a meme generator using ReactJS. In the meme generator, we have two text fields in which we enter the first textand last text. After writing the text when we click the Gen button, it creates a meme with an image and the text written on it.

In this React app, we have only one component: MemeGenerator. MemeGenerator contains a render method that returns a controlled form, the form contains two input fields and one Gen button. When the MemeGenerator component gets rendered on the screen, the componentDidMount() method gets activated and makes an API call, and stores the data received in an array. When the user fills the input field and clicks the Gen button, the form gets submitted, and a random image URL is assigned to the randomImg state variable. The image is shown on the screen along with the text.

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with ourJavaScript Course. Now at it's lowest price ever!

Prerequisite: The pre-requisites for this project are:

  • React
  • Functional and Class Components
  • React AJAX and API
  • ES6 

Getting Started with React: Our React app contains two components, the App component, and MemeGenerator component.



Index.js:

Javascript

App.js: App component renders single MemeGenerator component.

Javascript

MemeGenerator.js: The only component in our App is a MemeGenerator component. It contains four state variables and initially, all of them are set to empty string or empty array. When the component gets mounted on the screen, an API call is made and the data received is converted into JSON and stored in the state variable allMemeImgs[ ]. The MemeGenerator component renders a controlled form to the screen and when the user types the input, the handleChange method gets called, and the state variables topText and bottomText store the text typed by the user.  When the user clicks the Gen button, handleSubmit method gets called and a random image URL is stored in randomImg variable. When the randomImg gets the value, the meme is shown to the screen.

Below is the complete code of our MemeGenerator component.

Memes are great - they're such a fun way of describing ideas and opinions. So it's no coincidence that I picked a meme generator app as the capstone project in my free React course on Scrimba. The app works by pulling a random meme image from an API and placing your text over the top of it to create your very own, personalized meme.

So in this article, I'll give you a step-by-step guide to creating the app. If you ever get confused, you can also follow these steps in the Scrimba course, starting at this lecture.

And then if you like my teaching style and are in the mood for a tougher challenge after you complete this tutorial, please check out my upcoming advanced course on Scrimba.

Note: You should already be fairly familiar with some of the fundamental concepts of React, like components, state, props, and lifecycle methods. Also, this tutorial doesn't use Hooks, but in my upcoming course we'll cover Hooks in depth and get tons of practice using them.

1. Creating the boilerplate and rendering an App component

Creating the boilerplate task

The first thing we need to do is to create the boilerplate code for the app. To do this, we import and and use to render a component called , which we will create later. We then put the component at the 'root'. We also import from its file , which we will create shortly.

We then create our file. In it, we create a functional component called which, for now, returns a simple . We then export it. The allows us to check that the app is displaying correctly to the screen.

The resulting output is this:
Rendered Hello World

2. Creating the Header and MemeGenerator components

Creating the Header and MemeGenerator task

Next up, we create the Header and MemeGenerator components. The Header will only display elements, while MemeGenerator will call to the API and retain the data in state.

Let's start by creating the file. Since Header is a component which is only used to display, it should be a functional component. For now, the component should return a simple . After creating it, we then export Header.

Next, we create the file. As the component will be holding data and making calls to an API, it needs to be a class component. We still need to import React, and since it is going to be a class component, we'll import as well (which is a named import).

MemeGenerator needs a which calls and as it will be holding state, we add some empty state to it now. Like in the Header component, we render a simple to start with. We then export MemeGenerator.

Now, we import both Header and MemeGenerator into and create an instance of each one in our App component. In order to display the components correctly, we wrap them in a .

To complete the component, we add a trollface image by inserting an tag and setting the src to the image's URL. We then add a tag with the name of our app and wrap them both in the semantic HTML5 tag.

As styling is outside the scope of this course, the CSS styles have already been created and applied to the tag. The result is this:

Rendered Header

That said, learners can always play around with the styling and hone their CSS skills by themselves. With the now complete, the rest of the challenge will take place in

4. Initializing state

Initializing state task

We now have to initialize state so that it saves a top text, a bottom text and a random image, which is already supplied.

To do this, we build up the empty object we placed in the when we originally built it. We initialize and as empty strings and as the provided URL.

5. Making the API call

Making the API call task

Next, we make an API call to the provided URL and save the data returned (which is an array found in ) to a new state property called .
When we need to load data from an endpoint to use in our component, a good place to make the request is the lifecycle method. As soon as the component mounts, we use the native function to call to the provided URL.

This returns a promise which we turn into a Javascript object with the method.

Then we get the response which is useful to us by pulling the memes array from .

Now, we save the results to a new state property called . To do this, we initialize as an empty array.

Now, back in , we set state. As we are not interested in what the previous state was, we set to memes.

To ensure that it works, we the first item, which looks something like this:

console.log output

Here's an overview of the entire function.

6. Creating the input form

We now want to create a form which will eventually allow the user to input the top and bottom texts. We do this with an HTML tag and a simple which says 'Gen'. We style it with the pre-provided CSS.

Rendered Gen button

7. Adding input fields to the form

Adding input fields task

Next, it is up to us to add the two input fields (one for the top text and one for the bottom text). The form should be a controlled form, so we will need to add all the attributes needed in order for that to work. We will create the handler later.

We create two input fields which both have the type and appropriate name attributes ( and ). Rather than using labels, we use placeholders: 'Top Text' and 'Bottom Text'.

Lastly, in order to make this a controlled form, we set the value as equal to the current value in with and .

8. Creating the onChange handler.

Creating the onChange handler task

Now, we create the onChange handler, which will update the corresponding state on every change of the input field.

First, we create a function which receives an event.

Now, we set the of both input fields to equal .

We need to remember to bind the method in the constructor — a common gotcha for React developers.

To test the new function, we add a simple :

If it is correctly firing, you'll see something like this:
Rendered console.log("Working!")

Now to fill in the function. To do this, we want to pull the name and value properties from event.target so that we can get the name of the state we are supposed to update ( or ) and the value which is typed into the box.

We will now use these to update state. As we are not interested in what the previous state was, we can just provide an object in which we set the to the value typed into the input field.

9. Displaying a meme image alongside the top and bottom text

We now want the app to display a meme image alongside the top and bottom text. We insert an tag underneath the and set the which we initialized as its source by using . We then add two tags which display the corresponding text which is also saved in state. All of this is wrapped in a and styled with the pre-provided class.

We can now test the app by typing into the text boxes. As state is being correctly set on every keystroke, the text displayed on the image changes each time we type.

Rendered example of progress so far

10. Displaying a random meme image alongside the Top and Bottom text

Displaying a random meme image task

Now, we need to create a method which displays a meme image which it randomly chooses from our array when the button is clicked. The property on the chosen image in the array is .
We can break this task down into smaller parts.

Firstly, we set the form's to equal the name of our new method, which we will call .

We now create the function above the function. We need to preventDefault on the event, otherwise, the method will try to refresh the page.

We also need to bind in our .

Now, we need to get a random number, get the meme from that index and set to the of the random item.

To get a random number, we use . To make sure that it is one of the indices in our array, we multiply by the length of the array.

We now set to equal , with the index of as the we just got. We then add to the end of it.

Now, all we need to do is update the state by updating the randomImg property with .

Our completed function looks like this:

Completed Meme Generator

Working App

We now have completed the meme generator app, and get a different image every time we hit the button, which is then overlaid with the text we input.

To further our learning, we could play with code and see whether we can improve it, or try to get images from a different API. For some really heavy-duty practice, we could even delete all the code and try building it again from scratch.

Congratulations on following through the tutorial and learning all the skills used in this project.

Harsh truth XD. When you try to learn a programming language, it is always a challenge.

This is our favorite JavaScript joke, such irony. As you probably remember, HTML is not a programming language. 😁

Meme react js

Lie down on the bed. '' I decided to wait and see what happened next, so I flopped down on my back and threw my hands behind my head. My bolt did not have time to calm down completely, and now it was sticking out decently. Elena Nikolaevna was embarrassed and timidly added: - Not so, on the stomach.

I'll give you a massage.

REACTING TO UNUSUAL MEMES COMPILATION

She replied with a tinge of misunderstanding. - What kind of massage in a blouse. - I paraphrased her own words.

You will also be interested:

She began to take it in her mouth, it was very gentle and slow, I could hardly restrain myself. I lift her up to me, kiss her gently and begin to introduce him into her. I slowly drove her on her wet pussy with a member, she was already starting to moan, I realized that it was already time.

I slowly inserted the head into it, and when I pulled out, I saw the blood.
