  • Looks like the question actually should be why is request.body a string and not an object. http://expressjs.com/en/resources/middleware/body-parser.html or the request is not setting the correct content type. – epascarello Aug 03 '23 at 13:32

Use JSON.parse()

const input = '{"method":"setValue","params":{"cmd_Motor":true}}';
const result = JSON.parse(input);

I am not sure if I understood your question, but you can convert a string to a JSON object and you can also convert a JSON object to a string:

converting from string to json 

const myString = '{"method":"setValue","params":{"cmd_Motor":true}}';
const myJson = JSON.parse(myString);

console.log(myJson.method) // setValue
console.log(myJson.params.cmd_Motor) // true

converting from json to string 

const myJson = { method: 'setValue', params: { cmd_Motor: true } };
const myString = JSON.stringify(myJson);

console.log(myString);
