// If the file doesn't exist, the content will be an empty object by default.
let file = editJsonFile(`${__dirname}/foo.json`);
// Set a couple of fields
file.set("planet", "Earth");
file.set("city\\.name", "anytown");
file.set("name.first", "Johnny");
file.set("name.last", "B.");
file.set("is_student", false);
// Output the content
console.log(file.get());
// { planet: 'Earth',
// city.name: 'anytown',
// name: { first: 'Johnny', last: 'B.' },
// is_student: false }
// Save the data to the disk
file.save();
// Reload it from the disk
file = editJsonFile(`${__dirname}/foo.json`, {
autosave: true
});
// Get one field
console.log(file.get("name.first"));
// => Johnny
// This will save it to disk
file.set("a.new.field.as.object", {
hello: "world"
});
// Output the whole thing
console.log(file.toObject());
// { planet: 'Earth',
// name: { first: 'Johnny', last: 'B.' },
// is_student: false,
// a: { new: { field: [Object] } } }

I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).
However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:
Starring and sharing the projects you like :rocket:
—I love books! I will remember you after years if you buy me one. :grin: :book:
—You can make one-time donations via PayPal. I'll probably buy a coffee tea. :tea:
—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).
Bitcoin—You can send me bitcoins at this address (or scanning the code below): 1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6
Thanks! :heart:
If you are using this library in one of your projects, add it in this list. :sparkles:
