December 31, 2023 - In this example, binaryToAscii converts the binary data to an ASCII string, and asciiToBinary converts the ASCII string back to binary data. After decoding the ASCII string, you can then parse it as JSON using JSON.parse. Note that this example assumes that the binary data can be accurately represented using ASCII encoding, and it might not be suitable for arbitrary binary data.

This is safe to do because the JSON decoding will fail if it was unable to construct a list of Foo: public Flux<Foo> readFile() { ResolvableType type = ResolvableType.forType(List.class,Foo.class); Flux<DataBuffer> data = DataBufferUtils.read("classpath:test.json", new DefaultDataBufferFactory(), 4096); return new Jackson2JsonDecoder().decode(data, type, null, null) .map(Foo.class::cast); } Share ·

Converting a Buffer to JSON and Utf8 Strings in Nodejs | by Aman Mittal | HackerNoon.com | Medium
April 1, 2019 - The JSON specifies that the type of object being transformed is a Buffer, and its data. .toString() is not the only way to convert a buffer to a string.

How to convert buffer to JSON? - javascript
Yes. Your raw data is not a string. It's buffer containing bytes. You need to create a ByteArray from it and then convert that to a string before you attempt to parse it as JSON.

Tokenize the given Flux<DataBuffer> into Flux<TokenBuffer>. ... tokenizeArrayElements - if true and the "top level" JSON object is an array, each element is returned individually, immediately after it is received.

You need to stringify the json, not calling toString
var buf = Buffer.from(JSON.stringify(obj));
And for converting string to json obj :
var temp = JSON.parse(buf.toString());

Kindly copy below snippet
const jsonObject = {
"Name":'Ram',
"Age":'28',
"Dept":'IT'
}
const encodedJsonObject = Buffer.from(JSON.stringify(jsonObject)).toString('base64');
console.log('--encodedJsonObject-->', encodedJsonObject)
//Output --encodedJsonObject--> eyJOYW1lIjoiUmFtIiwiQWdlIjoiMjgiLCJEZXB0IjoiSVQifQ==
const decodedJsonObject = Buffer.from(encodedJsonObject, 'base64').toString('ascii');
console.log('--decodedJsonObject-->', JSON.parse(decodedJsonObject))
//Output --decodedJsonObject--> {Name: 'Ram', Age: '28', Dept: 'IT'}

r/learnjavascript on Reddit: How to convert Buffer object to usable JSON data?
July 19, 2020 -
The config file I'm reading from looks like this:
{
"projectId": "projectName",
"languageCode": "th",
"numberOfRepeats": "2"
}I'm trying to read this file but failing so far:
const defaultConfigFilePath = path.join(__dirname, '../../../configuration.json');
export function setConfigData(configFile = defaultConfigFilePath): ConfigData {
const fileContentBuffer: Buffer = fs.readFileSync(configFile);
const jsonData: ConfigData = fileContentBuffer.toJSON();
/*
Type '{ type: "Buffer"; data: number[]; }' is missing the following properties from type 'ConfigData': languageCode, numberOfRepeats, projectIdts(2739)
*/
const configData: ConfigData = JSON.parse(fileContentBuffer);
/*
const fileContentBuffer: Buffer
Argument of type 'Buffer' is not assignable to parameter of type 'string'.ts(2345)
*/
I'm having a tough time figuring out what the issue is exactly. The first error indicates the toJSON method does not return the data shape I expect. The 2nd error indicates parse can't even take a Buffer object. What is the solution then?

why not export a module? config.js const config = { "projectId": "projectName", "languageCode": "th", "numberOfRepeats": "2" }; module.exports = config; any given file const config = require("./config.js"); console.log(config.projectId) then you dont have to worry about any buffering or filesystem stuff. alternately, read this: https://stackabuse.com/reading-and-writing-json-files-with-node-js/ . you probably want JSON.parse rather than toJSON

Try adding an encoding to the readFileSync, it should return a more sensible type then. fs.readFileSync(configFile, 'utf8')

JSON.stringify and JSON.parse accept arguments called replacer and reviver respectively which allow customizing the parsing/encoding behavior. This module provides a replacer which encodes Buffer data as a base64-encoded string, and a reviver which turns JSON objects which contain buffer-like data (either as arrays of numbers or strings) into Buffer instances.
