How to import json files in js
Currently there is no way to directly import JSON files using JavaScript (ESM). You could load them in as data, but that would be going through a separate (usually asynchronous) API rather than using the module system such as fetch . If you're using a bundler (e.g. webpack, rollup, esbuild, etc.), they usually allow you to specify JSON in import statements from within your source code. Then, during bundling, those import statements are re-written to include your JSON through alternate means despite, to you, it appears to work no differently than any other source file. In the future we should be able to do this without the help of bundlers. For more information on that proposed feature, see: https://github.com/tc39/proposal-json-modules More on reddit.com

I had the same need (to test my angularjs app), and the only way I found is to use require.js:
var json = require('./data.json'); //(with path)
note: the file is loaded once, further calls will use the cache.

How to Read and Write JSON in JavaScript
Note that JSON.parse() accepts a valid JSON string value and returns a JavaScript value. In case of invalid JSON data, it throws a SyntaxError. Vanilla JavaScript does not allow you to deal with the file system, but you can do it in your back-end with Node.js.

For reading the external Local JSON file (data.json) using javascript, first create your data.json file:
data = '[{"name" : "Ashwin", "age" : "20"},{"name" : "Abhinandan", "age" : "20"}]';
Then,
Mention the path of the json file in the script source along with the javascript file
<script type="text/javascript" src="data.json"></script> <script type="text/javascript" src="javascript.js"></script>Get the Object from the json file
var mydata = JSON.parse(data); alert(mydata[0].name); alert(mydata[0].age); alert(mydata[1].name); alert(mydata[1].age);

The loading of a .json file from a hard disk is an asynchronous operation, and thus it needs to specify a callback function to execute after the file is loaded.
function readTextFile(file, callback) {
var rawFile = new XMLHttpRequest();
rawFile.overrideMimeType("application/json");
rawFile.open("GET", file, true);
rawFile.onreadystatechange = function() {
if (rawFile.readyState === 4 && rawFile.status == "200") {
callback(rawFile.responseText);
}
}
rawFile.send(null);
}
//usage:
readTextFile("/Users/Documents/workspace/test.json", function(text){
var data = JSON.parse(text);
console.log(data);
});
This function also works for loading a .html or .txt files, by overriding the mime type parameter to "text/html", "text/plain", etc.

The very last thing we do is to append the <h2>, <p>s, and <ul> inside the <article> (myArticle), then append the <article> inside the <section>. The order in which things are appended is important, as this is the order they will be displayed inside the HTML. Note: If you are having trouble getting the example to work, try referring to our heroes-finished.html source code (see it running live also.) Note: If you are having trouble following the dot/bracket notation we are using to access the JavaScript object, it can help to have the superheroes.json file open in another tab or your text editor, and refer to it as you look at our JavaScript.

I do it like this: const response = await fetch('./my_json_file.json'); const json = await response.json(); And that's it. Of course you'll have to perform it in an async function (unless you'd rather just use the .then() syntax), but this'll do the trick.

November 1, 2024 - Therefore, it is advisable to use require for loading static JSON files such as configuration files that don’t change often. Don’t use require if the JSON file you load keeps changing, because it will cache the loaded file, and use the cached version if you require the same file again. Your latest changes will not be reflected. Assuming you have a config.json file with the following contents: ... You can load the config.json file in a JavaScript file using the code below.

I have a simple html file:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="Dashboard"> <title>Dashboard</title> </head> <body> <script type="text/javascript" src="update.js"></script> <h1>Price of Stocks:</h1> <h2 id="ap">Apple: </h2> <h2 id="ts">Tesla: </h2> <button onclick="updatePrice();">update</button> </body> </html>
update.js looks like this:
const src = require("./prices.json");
function updatePrice() {
document.getElementById("ap").innerHTML = "Apple: " + src.Apple.price;
document.getElementById("ts").innerHTML = "Tesla: " + src.Tesla.price;
};The json file is as follows: (prices are arbitrarily entered right now)
{
"Apple": {
"price": 10.0
},
"Tesla": {
"price": 10.0
}
}This html file is not on a webserver and loads directly from C://, the prices.json and update.js are located in the same directory as index.html
The main issue here is that I cannot use require outside of node.js, I know I can use browserify, but surely there is a better way to read data from that json file.

You can use the fetch API to load data from a JSON file: fetch("./prices.json").then((response) => { return response.json() }).then(data => {console.log(data)}) //output: Object {Apple: {...}, Tesla: {...}}

Low tech solution: change it to a js-file that exports an object. For any good solution you need a more sophisticated setup like a webserver.
