write-json-file
Advanced tools
Package description
The write-json-file npm package allows you to write JSON data to a file in a simple and straightforward manner. It is useful for saving configuration files, data storage, and other scenarios where JSON data needs to be persisted to the filesystem.
Write JSON to a file
This feature allows you to write a JSON object to a specified file. The example demonstrates writing a simple JSON object to a file named 'foo.json'.
const writeJsonFile = require('write-json-file');
(async () => {
await writeJsonFile('foo.json', {foo: true});
})();Write JSON to a file with options
This feature allows you to specify options such as indentation when writing JSON to a file. The example demonstrates writing a JSON object to a file with an indentation of 2 spaces.
const writeJsonFile = require('write-json-file');
(async () => {
await writeJsonFile('foo.json', {foo: true}, {indent: 2});
})();Write JSON to a file with replacer function
This feature allows you to use a replacer function to modify the JSON data before writing it to a file. The example demonstrates writing a JSON object to a file while excluding the 'bar' property.
const writeJsonFile = require('write-json-file');
(async () => {
await writeJsonFile('foo.json', {foo: true, bar: false}, {replacer: (key, value) => key === 'bar' ? undefined : value});
})();The jsonfile package provides similar functionality for reading and writing JSON files. It offers a simple API for both synchronous and asynchronous operations. Compared to write-json-file, jsonfile includes both read and write capabilities in a single package.
The fs-extra package extends the native Node.js fs module with additional methods, including methods for reading and writing JSON files. It provides a more comprehensive set of file system utilities compared to write-json-file, which focuses solely on writing JSON data.
The json-write package is another alternative for writing JSON data to files. It offers a straightforward API similar to write-json-file but with fewer configuration options. It is a simpler and more lightweight option for basic JSON writing tasks.
