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.

May 6, 2022How 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

Let's say you have a JSON file containing a list of objects, like the one below: [ {"name": "John Doe", "age": 32}, {"name": "Joe Doe", "age": 30}, {"name": "Alice", "age": 28} ] You can parse this using JSON.parse() just as we did above, except that the function will return a JavaScript array: var fs = require('fs'); fs.readFile('file-with-array.json', 'utf-8', function (err, data) { if (err) throw err; var arr = JSON.parse(data); arr.forEach((obj) => { console.log(`${obj.name} is ${obj.age} years old`) }) });

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.

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. In detail, the native fs module enables you to watch, read, and write files in the file system of your back-end application.

Every explaination I see either just copy pastes the JSON-data into the JS file, or they use code that looks like straight up dark magic. There has got to be a simpler way right?
If there is no "simple" way to do it, then what is the way that requires the least explaining, since my brain refuses to use code I don't completely understand.
Thank you!

Well my assumption is you are trying to use a JSON file as a database. Your only option really is to read the entire JSON file into memory, manipulate it and the rewrite it to the file. Otherwise use SQLite.

r/learnjavascript on Reddit: How to import a JSON file into a javascript file to read and then output to the browser?
January 11, 2022 -
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.
