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);
//Create or append to an array
file.append("classes", "fysics");
//You can even append objects
file.append("classes", { class: "Computer Science", where: "KULeuven" });
// Output the content
console.log(file.get());
// { planet: 'Earth',
// city.name: 'anytown',
// name: { first: 'Johnny', last: 'B.' },
// is_student: false,
// classes: [
// 'fysics',
// {
// 'class': 'Computer Science',
// 'where': 'KULeuven'
// }
// ]
// }
//if you want to remove the last element from an array use pop
file.pop("classes")
// 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] } } }

:sparkling_heart: Support my projects
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:
- [![Buy me a book][badge_amazon]][amazon]—I love books! I will remember you after years if you buy me one. :grin: :book:
- [![PayPal][badge_paypal]][paypal-donations]—You can make one-time donations via PayPal. I'll probably buy a ~~coffee~~ tea. :tea:
- [![Support me on Patreon][badge_patreon]][patreon]—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):
