Jsonify-js NPM

jsonify-js - JSON with Promise Support

A simple and light-weight JSON handler with promise support. It provide promised version of the JSON built-in methods such as JSON.Stringify and JSON.parse. It also had an utility method (JSONLogger) to log the JSON data on to a JSON file.

Installation

npm install jsonify-js

Usage

You can use the JSONStringify and JSONParse methods using Promises or Async/Await syntax.

Using Promise Syntax

JSONStringify - Converts the js object/array into stringified JSON.

const { JSONStringify } = require('jsonify-js')

const user = {
  name: 'John',
  age: 30,
  city: 'New York',
}

JSONStringify(user)
  .then((result) => {
    console.log(result)
    // Handle the stringified result
  })
  .catch((error) => {
    // Handler error
    console.error(error)
  })

JSONParse - Converts the stringified JSON into js object/array.

const { JSONParse } = require('jsonify-js')

const stringifiedData = '{"name":"John","age":30,"city":"New York"}'

JSONParse(stringifiedData)
  .then((result) => {
    // Handle the JSON parse result
    console.log(result)
  })
  .catch((error) => {
    // Handler error
    console.error(error)
  })

Using Async/Await Syntax

JSONStringify - Converts the js object into stringified JSON.

const { JSONStringify } = require('jsonify-js')

const getStringifiedData = async () => {
  try {
    const user = {
      name: 'John',
      age: 30,
      city: 'New York',
    }

    const stringifiedData = await JSONStringify(user)

    return stringifiedData
  } catch (err) {
    // Handler error
    console.error(err)
  }
}
const main = async () => {
  const result = await getStringifiedData()
  console.log('Result:', result)
}

main()

JSONParse - Converts the stringified JSON into js object.

const { JSONParse } = require('jsonify-js')

const getParsedData = async () => {
  try {
    const stringifiedData = '{"name":"John","age":30,"city":"New York"}'

    const parsedData = await JSONParse(stringifiedData)

    return parsedData
  } catch (err) {
    // Handler error
    console.error(err)
  }
}
const main = async () => {
  const result = await getParsedData()
  console.log('Result:', result)
}

main()

JSON logger

JSONLogger - Can be used to log the JSON data to a JSON file.

const { JSONLogger } = require('jsonify-js')

const user = {
  name: 'John',
  age: 30,
  city: 'New York',
}

// Save the stringified data in a JSON file
JSONLogger({ data: user, space: 2, filePath = './log.json' })

Documentation

JSONStringify

JSONStringify works similar to the build-in JSON method JSON.stringify. You can also pass the optional parameters such as replacer or space.

Syntax

JSONStringify(value)
JSONStringify(value, replacer)
JSONStringify(value, replacer, space)

Read more about the optional parameters here

JSONParse

JSONParse works similar to the build-in JSON method JSON.parse. You can also pass the optional parameters reviver.

Syntax

JSONParse(text)
JSONParse(text, reviver)

Read more about the optional parameters here

JSONLogger

JSONLogger can be used to log the JSON data into a JSON file.

Syntax

JSONLogger({
  data,
  filePath,
  replacer,
  space,
  writeFileOption,
  customSuccessMessage,
})

Parameters:

data (required): Data in object or array format.
filePath (optional): Location/Path of the JSON file where you want to log/save the data. Default value is set to ./log.json.
replacer (optional): You can use the custom replacer function. Default value is null. Refer this for more details.
space (optional): You can pass in the space value in number. space = 2 means normal space and space = 4 means tab space. Refer this for more details.
fileWriteOptions (optional): Refer this for more details. Default value is set to utf8.
customSuccessMessage (optional): You can pass the custom message which will be displayed on console on completion of logging. Default value is set to jsonify-js: Log file has been created!.
