How do I display json data using Reactjs?

I have products.json in which I have data. Now, I wish to render it using Reactjs.
products.json
[
{
"id": 1,
"productName": "Fjallraven - Foldsack No. 1 Backpack, Fits 15 Laptops",
"price": 109.95,
"description": "Your perfect pack for everyday use and walks in the forest. Stash your laptop (up to 15 inches) in the padded sleeve, your everyday",

"description": "Slim-fitting style, contrast raglan long sleeve, three-button henley placket, light weight & soft fabric for breathable and comfortable wearing. And Solid stitched shirts with round neck made for durability and a great fit for casual fashion wear and diehard baseball fans. The Henley style round neckline includes a three-button placket.",

"specification": {}
}
]
app.js
function App(){
return(
)
}
I want the json data to be rendered through app.js.
My Take On:
I'm new to Reactjs and JSON and was thinking of using fetch, response but I'm not sure how can I do it.
Can someone please help?

First you have to put your data in variable
For example:
const data = [
{
"id": 1,
"productName": "Fjallraven - Foldsack No. 1 Backpack, Fits 15 Laptops",
"price": 109.95,
"description": "Your perfect pack for everyday use and walks in the forest. Stash your laptop (up to 15 inches) in the padded sleeve, your everyday",
"category": "men's clothing",
"image": "https://fakestoreapi.com/img/81fPKd-2AYL._AC_SL1500_.jpg",
"specification": {}
},
{
"id": 2,
"productName": "Mens Casual Premium Slim Fit T-Shirts ",
"price": 22.3,
"description": "Slim-fitting style, contrast raglan long sleeve, three-button henley placket, light weight & soft fabric for breathable and comfortable wearing. And Solid stitched shirts with round neck made for durability and a great fit for casual fashion
wear and diehard baseball fans. The Henley style round neckline includes a three-button
placket.",
"category": "men's clothing",
"image": "https://fakestoreapi.com/img/71-3HjGNDUL._AC_SY879._SX._UX._SY._UY_.jpg",
"specification": {}
}
]
The you have to map through your array
Like this
function App(){
return (
<div>
{data.map((d) => (
<div key={d.id}>
<p>ID: {d.id}</p>
<p>Product Name: {d.productName}</p>
<p>Price: {d.price}</p>
<p>Description: {d.description}</p>
<p>Category: {d.category}</p>
<p>
Image: <img src={d.image} width="100" />
</p>
<br />
<br />
</div>
))}
</div>
);
}
Then you can add CSS to make it look better!

Unable to get the value from object

I'm creating an app in React and trying to get data from object via function for rendering.
However, I'm getting errors and I banged my head on this for many hours but failed.
Help will be really appreciated.
I'm getting the following error:
TypeError: Cannot read property 'title' of undefined
I'm pasting the code below (Please see my comments inline):
render() {
return (
<div aria-live="assertive">
<h2>Headlines</h2>
<ul>
{
Object.values(this.state.news).map((item) => {
console.log(item[0].title); //Doesn't work however:
console.log(item[0]); //This works and prints the object to the console properly.
})
}
</ul>
</div>
}
And here is the object structure:

So, here I'm unable to identify that if the complete object is being printed out in the console by using the second line (Please refer the code above) then why it is giving the error in first console.log call.
Please help

The corresponding map function is working with only with arrays. U are trying to output normal objects. Just Add
<ul> {title} </ul>
<ul> {feed.title} </ul>

Is it possible to get a list of all items in an array of objects that match items in another array?

I'm working on a React project that'll allow me to search through a list of games to help me decide what to play based on what I'm in the mood for, currently I can add games to a JSON file but I'm really struggling with the searching part.
Right now, to add a new game, you'll enter the title, genre(s) and a description of the game. The genre field is a ReduxForm FieldArray object, and I think that's what's giving me the trouble. Here's my current JSON file
{
"games": [
{
"name": "Rainbow Six: Siege",
"genres": [
{
"genre": "tactical"
},
{
"genre": "shooter"
}
],
"description": "tactical team based shooter",
"id": 1
},
{
"name": "Resident Evil 2",
"genres": [
{
"genre": "horror"
},
{
"genre": "survival"
},
{
"genre": "shooter"
}
],
"description": "classic resident evil 2 remake in 2019",
"id": 2
},
{
"name": "Rocket League",
"genres": [
{
"genre": "cars"
},
{
"genre": "competition"
},
{
"genre": "one more game"
}
],
"description": "soccar!",
"id": 3
}
]
}
This is the dummy data I'm using to search:
const searchedGenres = 'horror, shooter';
const searchedList = searchedGenres.split(', ');
let foundGame = [];
Once I get the search working with this data, the plan is to allow me to just type in data on the frontend in one textbox, so "horror, shooter" would be my search term. The result from this search should only return Resident Evil 2, however I'm also receiving Rainbow Six: Siege as a result, even though it's missing one of my requested genres.
searchedList.forEach(searchedGenre => {
this.props.games.map(game => {
if (
game.genres.find(
({ genre }) =>
genre.toLowerCase() ===
searchedGenre.toLowerCase().trim()
) !== undefined
) {
foundGames.push(game);
}
});
});
I understand why I'm getting both Rainbow Six and Resident Evil as a result, because I'm not actually checking that both genres are in the games genres when I add the game to the foundGames array, but I'm completely lost on how I'd go about making sure all of the genres are in a game before I add it.

This would be a bit easier if your genres was a simple array of strings rather than objects, but still you can check pretty succinctly by leveraging some() and every() within filter() (btw filter() is a better choice than map() + push() here)
let games = [{"name": "Rainbow Six: Siege","genres": [{"genre": "tactical"},{"genre": "shooter"}],"description": "tactical team based shooter","id": 1},{"name": "Resident Evil 2","genres": [{"genre": "horror"},{"genre": "survival"},{"genre": "shooter"}],"description": "classic resident evil 2 remake in 2019","id": 2},{"name": "Rocket League","genres": [{"genre": "cars"},{"genre": "competition"},{"genre": "one more game"}],"description": "soccar!","id": 3}]
const searchedGenres = 'horror, shooter';
const searchedList = searchedGenres.split(', ');
let foundGame = games.filter(game => searchedList.every(searchItem => game.genres.some(g => g.genre == searchItem) ))
console.log(foundGame)
The filter condition basically says you want every game in searchedList to match at least one genre in the game. This will make it only return games that match every genre.

I want to be able to call the relevent information mapped to a component as below
class ResultsLists extends React.Component {
constructor(props) {
super(props)
this.state = {
results: resultsData
}
}
render() {
const results = this.state.results.results.map((result) =>
<li>{result}</li>
);
return (
<div className="rst-List">
<ul className="rst-List_Items">
{results}
</ul>
</div>
)
}
}
I can't seem to get it too work and am getting the error - Objects are not valid as a React child. There seems to be a varying variety as to why this isn't working, wondered whether someone could sanity check.

You're mapping over the results, but then you're putting the whole result object into the JSX.
This is an example of how to map over data:
const someData = [{ name: "Colin" }, { name: "Ricardo" }];
const App = () => {
const temp = someData.map(o => <li>{o.name}</li>);
return (
<div>
<ul>{temp}</ul>
</div>
);
};
Note that we have {o.name} and not just {o}.
Working example here.
So in your case, you need something like:
const results = this.state.results.results.map((result) =>
<li>{result.title}</li>
);
