Calling a local json file and parsing data in ReactJS - json

Question

I have the following json file. Right now, i have kept this in my ReactJS project itself locally. Later on planning to move in a server location.
abtestconfig.json
[
{
"abtestname": "expAButton",
"traffic": 1,
"slices":
[
"orange",
"blue"
]
},
{
"abtestname": "expTextArea",
"traffic": 0.5,
"slices":
[
"lightgrey",
"yellow"
]
}
]
I want to read and get data and parse it and apply in a function. I got some reference sample code and trying to use fetch api to react json file with the following code.
After reading this json file, i will have to pass the data in abtest function, as you can see now it's sending with hard coded value abtest('expAButton', 0.75).slices('orange', 'blue').run(function ()
I have the following doubts and wanted to get your guidance / clarification.
1. Is it correct way to read json file using fetch api? Is there any other best approach?
2. When I use fetch api like mentioned below, console log displays GET http://localhost:8080/abtesting/abtestconfig.json 404 (Not Found)
app.jsx file:
import './abtesting/abtestconfig.json';
class App extends React.Component {
constructor() {
super();
this.onClick = this.handleClick.bind(this);
this.onClickNewUser = this.handleNewUser.bind(this);
this.state = {
bgColor: '',
data: []
}
};
handleNewUser (event) {
abtest.clear();
window.location.reload();
}
render() {
return (
<Helmet
/>
<p><b>A/B Testing Experience</b></p>
<div className="DottedBox">
<p><button id = "newUserButton" onClick = {this.onClickNewUser} style={{backgroundColor:"red"}}>Welcome and click here</button></p>
</div>
);
}
handleClick () {
abtest('expAButton', 0.75).slices('orange', 'blue').run(function () {
expAButton.style.backgroundColor = this.slice.name;
});
}
setStyle (stylecolor) {
this.setState({
bgColor: stylecolor
})
}
componentDidMount () {
this.handleClick();
fetch('./abtesting/abtestconfig.json').then(response => {
console.log(response);
return response.json();
}).then(data => {
// Work with JSON data here
console.log(data);
}).catch(err => {
// Do something for an error here
console.log("Error Reading data " + err);
});
}
}
export default hot(module)(App);
