Prettify JSON

This is a library for Ballerina, to prettify JSON values. Since the Ballerina language supports json as a built-in type, this can be used to print JSON values easily.

Overview

This module provides an API to prettify json values, which are a native type in the Ballerina language.

Usage

This module has a single API: prettify. It takes a json value as the first argument. An optional indentation parameter can be provided if a custom number of spaces are needed as the indentation. Otherwise, the default 4 spaces will be used as the indentation.

Following are the example usages.

Prettify with default indentation

import ballerina/io;
import thisarug/prettify;

public function main() {
    json value = {
        name: "Walter White",
        age: 51,
        address: {
            number: 308,
            street: "Negra Arroyo Lane",
            city: "Albuquerque"
        }
    };
    string prettified = prettify:prettify(value);
    io:println(prettified);
}

This will print the following:

{
    "name": "Walter White",
    "age": 51,
    "address": {
        "number": 308,
        "street": "Negra Arroyo Lane",
        "city": "Albuquerque"
    }
}

Prettify with custom indentation

import ballerina/io;
import thisarug/prettify;

public function main() {
    json value = {
        name: "Walter White",
        age: 51,
        address: {
            number: 308,
            street: "Negra Arroyo Lane",
            city: "Albuquerque"
        }
    };
    string prettified = prettify:prettify(value, 2);
    io:println(prettified);
}

This will print the following:

{
  "name": "Walter White",
  "age": 51,
  "address": {
    "number": 308,
    "street": "Negra Arroyo Lane",
    "city": "Albuquerque"
  }
}
