Enforcing new line character in a json response

When sending a JSON response, it's common to include newline characters (\n) to separate lines of text or to format the output in a human-readable way. However, JSON itself does not have a built-in concept of newline characters, and it's up to the client-side application to interpret and display the response accordingly.

That being said, there are a few ways to enforce newline characters in a JSON response:

Use a JSON serializer that supports newline characters: Some JSON serializers, such as Jackson in Java or Newtonsoft.Json in.NET, allow you to configure the serialization process to include newline characters. For example, you can use the PrettyPrint feature in Jackson to format the JSON output with indentation and newline characters.
Use a custom JSON serializer: You can create a custom JSON serializer that inserts newline characters into the output. For example, you can use a regular expression to replace newline characters in the input data with the desired newline character (\n).
Use a JSON formatting library: There are libraries available that can format JSON output with newline characters, such as json-format in Node.js or json-pretty-print in Python.
Use a HTTP response header: You can set the Content-Type header of the HTTP response to text/json; charset=utf-8 and include newline characters in the response body. This will allow the client-side application to interpret the response as JSON and display it with newline characters.

Here are some examples of how you can enforce newline characters in a JSON response:

Java (using Jackson)

ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
String json = mapper.writeValueAsString(data);

.NET (using Newtonsoft.Json)

JsonSerializer serializer = new JsonSerializer();
serializer.Formatting = Formatting.Indented;
string json = serializer.Serialize(data);

Node.js (using json-format)

const jsonFormat = require('json-format');
const data = {... };
const formattedJson = jsonFormat(data, null, 2);

Python (using json-pretty-print)

import json
data = {... }
formatted_json = json.dumps(data, indent=2)

Remember that the client-side application should be able to interpret and display the response correctly, regardless of whether newline characters are included in the JSON response.
