I am working with a hi.json file that contains an object. In my JavaScript code, I import this JSON file like so:
var obj = require("hi.json");
Now, I need to figure out how to write data into the JSON file programmatically using JavaScript. Is it possible to do something like this?
obj["key"] = "value";
// This change should also be saved in hi.json
Is it possible to write to a JSON file using JavaScript?
One way to achieve this is by utilizing the a element, adding a download attribute, and constructing a data URI
var data = require("example.json");
data["key"] = "value";
// Desired save operation
var link = document.createElement("a");
link.download = "example.json";
link.href = "data:application/json;charset=utf-8," + JSON.stringify(data);
document.body.appendChild(link);
link.click();
var data = {
"key": "undefined"
};
data["key"] = "value";
// Desired save operation
var link = document.createElement("a");
link.download = "example.json";
link.href = "data:application/json;charset=utf-8," + JSON.stringify(data);
document.body.appendChild(link);
