Unable to Import JSON data from local file using ES6 import in a React Redux Webpack App
I am trying to learn building a React + Redux application architecture using Web Pack 3 for bundling. I am trying to work with temporary JSON files for data sets and importing them into Service files which want to use the data returned from the imported JSON.
I try to use the imported JSON in Promise.resolve(JSON) and somehow the value seems to be undefined.
Note: This block is inside in IIFE block.
Find the service code below.
import jsonVal from './josnFile.json';
export default (function() {
return {
method1: methodName1,
method2: methodName2,
...
}
function methodName1(){
return new Promise((resolve, reject) => {
resolve(jsonVal);
// ...usual then, catch blocks for returning rejects
});
}
}());
After all this flow, I have set up the reducers and actions to appropriately update the Redux state. But no update happens because the JSON data is always undefined and when I try to pass this down to the presentational React components via Redux connect (mapStateToProps), its undefined too.
I want to know what should I do to include this JSON for mocking APIs.
Whether I have to use a JSON loader in webpack or any other solution?
Note: I am using babel-node to transpile ES6 code
json reactjs webpack redux

1. Are you sure the path to json is correct? I see that you're trying to import./josnFile.json. There's a typo: "josnFile.json" -> "jsonFile.json" ;) 2. Have you tried with json-loader for webpack? npmjs.com/package/json-loader

on a side note, you don't need an IIFE because everything is scoped to the module

@jimmyweb - Yes, Path to json is correct, this is just a sample code I used here, and also I have tried using webpack JSON loader. Still same results.
