What is the best way to save the data stored in the project object to a .json file using JavaScript?
To store the JSON object in a file named file.json, you can use the following code snippet.
const FileSystem = require("fs");
FileSystem.writeFile('file.json', JSON.stringify(data), (err) => {
if (err) throw err;
});
JSON.stringify in ES 5.1 converts objects into JSON strings.
let jsonData = JSON.stringify(data);
Writing to files in JavaScript requires a non-standard method from the host environment. For instance, Node.js offers the writeFile function in its File System module.
This is a simplified method I often use for debugging purposes, similar to the top answer:
require('fs').writeFile('file.json', JSON.stringify(proj), (error) => {
if (error) {
throw error;
}
});
If you're looking to retrieve a file in a web browser using JavaScript, one method involves utilizing a dataUri:
var dataUri = "data:application/json;charset=utf-8;base64," + btoa(JSON.stringify(project));
<a download="project.json" href=dataUri>project.json</a>
