What is edit-json-file?

The edit-json-file npm package allows you to easily read, edit, and write JSON files in a simple and straightforward manner. It provides a set of methods to manipulate JSON data without having to manually parse and stringify the JSON content.

What are edit-json-file's main functionalities?

Read JSON file

This feature allows you to read the contents of a JSON file. The `get` method retrieves the entire JSON object from the file.

const editJsonFile = require('edit-json-file');
let file = editJsonFile(`${__dirname}/data.json`);
console.log(file.get());

Set a value

This feature allows you to set a value in the JSON file. The `set` method takes a key and a value, and updates the JSON object. The `save` method writes the changes to the file.

const editJsonFile = require('edit-json-file');
let file = editJsonFile(`${__dirname}/data.json`);
file.set('name', 'John Doe');
file.save();

Unset a value

This feature allows you to remove a key-value pair from the JSON file. The `unset` method takes a key and removes it from the JSON object. The `save` method writes the changes to the file.

const editJsonFile = require('edit-json-file');
let file = editJsonFile(`${__dirname}/data.json`);
file.unset('name');
file.save();

Append to an array

This feature allows you to append a value to an array in the JSON file. The `append` method takes a key and a value, and adds the value to the array associated with the key. The `save` method writes the changes to the file.

const editJsonFile = require('edit-json-file');
let file = editJsonFile(`${__dirname}/data.json`);
file.append('items', 'newItem');
file.save();

Save the file

This feature allows you to save the changes made to the JSON file. The `save` method writes the updated JSON object back to the file.

const editJsonFile = require('edit-json-file');
let file = editJsonFile(`${__dirname}/data.json`);
file.set('name', 'John Doe');
file.save();

:cloud: Installation

# Using npm
npm install --save edit-json-file

# Using yarn
yarn add edit-json-file

:clipboard: Example

const editJsonFile = require("edit-json-file");

// 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);
//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:
—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:
