I would just put it in a file called fakeData. Might be a quick workaround if all you're attempting to do is work with fake data to get better at using react. Another option would be to use jsonstub. Marvin Dick. Thanks, I'll check this approach tomorrow to see if I can use this instead until I've found a way to do it via url.
Is the concert component also in the src folder? I can imagine that the relative path is the source of the problem. Did you try it with an absolute path?

I can't believe that I didn't notice something like this. Want to read more?React is the one of the most popular frontend framework out there and more developers are increasing learning how to build real life applications with React. While learning React, you will eventually get to a point when you need to integrate APIs in your React application. We will be building a simple contact list application to display the contact's name, email and we will store a catch phrase of a contact.
We will make use of this endpointit contains a JSON dump of data needed for our contact list application. We will be creating our React Application using a neat tool called create-react-appthis is a boilerplate that helps you set up a proper folder structure and assets binding for your React application. Run this command on your terminal.Ansible s3 tags
Next, we will create a new project using create-react-app. So you can switch into your preferred directory and run this command on your terminal. This will generate some scaffolds you need to get your React application running as quick as possible.
The next step is to modify the App. If you noticed, we got rid of import logo from '. Next, we have to link bootstrap's CDN in the index. When this is done we will render a bootstrap card in the App. If we reload our application the following changes will reflect showing the contact's name, email and catch phrase in a bootstrap card.
Our application will parse and display the data in a presentable manner, making it appealing to the user. Below is a typical JSON response from the contact list dump :. A state is simply an object that holds data pending to be rendered.
This is where we will store the output from the API call.

All Rights Reserved. Powered by W3.Thanks to its uniformity and simplicity, JSON has almost completely replaced XML as the standard data exchange format in software, particularly in web services. In this article we'll explain how to perform these functions.
Let's first see how we can read a file that has already been created. But before we do that we need to actually create the file. Open a new window in your favorite text editor and add the following text to it:.
There are two functions available in this module that we can use to read files from the file system: readFile and readFileSync. Although both of these functions perform similar tasks i. The readFileSync function reads data from a file in a synchronous manner. This function blocks the rest of the code from executing until all the data is read from a file. The function is particularly useful when your application has to load configuration settings before it can perform any other tasks.
To continue with our example, let's use this function to read the "student. Add the following code to a '. In the above Node. Next we use the readFileSync function and pass it the relative file path to the file that we want to read.
If you print the object rawdata to the console, you will see raw data in a Buffer on the console screen:. However, we want to read the file in its JSON format, not the raw hex data.
This is where the JSON. Now, if you print the student object on the console, you will get the following output:. As you can see, the JSON from our file was successfully loaded in to the student object. Unlike readFileSync function, the readFile function reads file data in an asynchronous manner.
When a readFile function is called, the file reading process starts and immediately the control shifts to next line executing the remaining lines of code. Once the file data has been loaded, this function will call the callback function provided to it. This way you aren't blocking code execution while waiting for the operating system to get back to you with data. In our example, the readFile function takes two parameters: The path to the file that is to be read and the callback function that is to be called when the file is read completely.
You can optionally also include a parameter with options, but we won't be covering those in this article.
