Import JSON file in React with data format error - json

Question

I tried to import a JSON file in my React project, but got the parsing error:
json file:testData.json
{
"data": {
"articles": [
{
"id": "95c12a8f6c88953ca8f8a39da25546e6",
"title": "Introducing React's Error Code System",
"date": "Mon Jul 11 2016 00:00:00 GMT+0000 (UTC)",
"authorId": "2c6aa2cfe3449467d329fa17d6ea230f",
"body": "Building a better developer experience has been one of the things that React deeply cares about, and a crucial part of it is to detect anti-patterns/potential errors early and provide helpful error messages when things (may) go wrong. However, most of these only exist in development mode; in production, we avoid having extra expensive assertions and sending down full error messages in order to reduce the number of bytes sent over the wire."
}
],
"authors": [

"firstName": "Andrew",
"lastName": "Clark",

}
]
}
}
DataApi.js file:
export default class DataApi {
// property: rawData
constructor(rawData) {
this.rawData = rawData;
}
mapIntoObject(arr) {
return arr.reduce((acc, curr) => {
acc[curr.id] = curr;
return acc;
}, {});
}
getArticle() {
return this.mapIntoObject(this.rawData.articles);
}
getAuthors() {
return this.mapIntoObject(this.rawData.authors);
}
}
And I tried to import JSON data in this file:
import DataApi from "./DataApi"; // object to process data
import { data } from "./testData.json"; // raw data
// create a api object to host raw data
let api = new DataApi(data);
const articles = api.getArticle();
console.log(articles);
then I got the error:(the import directory are correct):
2:13 error Parsing error: Unexpected token, expected ";"
1 | {
> 2 | "articles": [
| ^
3 | {
4 | "id": "95c12a8f6c88953ca8f8a39da25546e6",
5 | "title": "Introducing React's Error Code System",
What is the problem?

Answer 1

You can do export default
testData.json:
const data = {
"data": {
"articles": [
{
"id": "95c12a8f6c88953ca8f8a39da25546e6",
"title": "Introducing React's Error Code System",
"date": "Mon Jul 11 2016 00:00:00 GMT+0000 (UTC)",
"authorId": "2c6aa2cfe3449467d329fa17d6ea230f",
"body": "Building a better developer experience has been one of the things that React deeply cares about, and a crucial part of it is to detect anti-patterns/potential errors early and provide helpful error messages when things (may) go wrong.

}
]
}
}
export default data;
and while importing
With json-loader installed, you can use
import data from "./testData.json";
or If you have used create-react-app to scaffold your project, the module is already included, you just need to import your json:
import data from "./testData";
To install json-loader
npm install --save-dev json-loader
And add below config to your webpack.config.js
webpack.config.js
module.exports = {
module: {
loaders: [
{
test: /\.json$/,
loader: 'json-loader'
}
]
}
}

You have to export your json data, your json data should be like this.
export const data = {
"data": {
"articles": [
{
"id": "95c12a8f6c88953ca8f8a39da25546e6",
"title": "Introducing React's Error Code System",
"date": "Mon Jul 11 2016 00:00:00 GMT+0000 (UTC)",
"authorId": "2c6aa2cfe3449467d329fa17d6ea230f",
"body": "Building a better developer experience has been one of the things that React deeply cares about, and a crucial part of it is to detect anti-patterns/potential errors early and provide helpful error messages when things (may) go wrong.

}
],
"authors": [
{
"id": "d85577ea34ae50f2dac5347b5219aa23",

"lastName": "Clark",
"website": "https://twitter.com/acdlite"
}
]
}
}
change .json to .js extention, while importing
import { data } from "./testData"; // raw data
