Fetch local JSON file from public folder ReactJS
I think your fetch argument is wrong. It should be
fetch('data/mato.json')
As long as data files are placed in public folder, it should work in Chrome also as in my project.So, fetch('data/mato.json') is enough for it.
You also need to pass in some headers indicating the Content-Type and Accept as application/json to tell your client that you are trying to access and accept some JSON resource from a server.
const getData=()=>{ fetch('data/mato.json' ,{ headers : { 'Content-Type': 'application/json', 'Accept': 'application/json' } } ) .then(function(response){ console.log(response) return response.json(); }) .then(function(myJson) { console.log(myJson); }); } useEffect(()=>{ getData() },[])
