In Node.js, the method http.response.end() is used to terminate an HTTP response. It can take an optional parameter to send as the response body to the client.<\/p>\n

The general format for using the http.response.end() method is as follows:<\/p>\n

response.end<\/span>([data][, encoding][, callback])\r\n<\/code><\/pre>\n
Explanation of parameters:<\/p>\n
    \n
  1. Data (optional): The response body data to be sent to the client. It can be a string, a Buffer object, or a readable stream. If this parameter is not provided, the response body will be empty.<\/li>\n
  2. Encoding (optional): If the data parameter is a string, you can specify its encoding, which defaults to utf-8.<\/li>\n
  3. Optional callback: A function that can be called after the response has ended.<\/li>\n<\/ol>\n
    Example of use:<\/p>\n
      \n
    1. Send a simple response body.<\/li>\n<\/ol>\n
      const<\/span> http = require<\/span>('http'<\/span>);\r\n\r\nconst<\/span> server = http.createServer<\/span>((req, res<\/span>) =><\/span> {\r\n  res.end<\/span>('Hello, World!'<\/span>);\r\n});\r\n\r\nserver.listen<\/span>(3000<\/span>);\r\n<\/code><\/pre>\n
        \n
      1. Send response body using Buffer object.<\/li>\n<\/ol>\n
        const<\/span> http = require<\/span>('http'<\/span>);\r\n\r\nconst<\/span> server = http.createServer<\/span>((req, res<\/span>) =><\/span> {\r\n  const<\/span> data = Buffer<\/span>.from<\/span>('Hello, World!'<\/span>, 'utf-8'<\/span>);\r\n  res.end<\/span>(data);\r\n});\r\n\r\nserver.listen<\/span>(3000<\/span>);\r\n<\/code><\/pre>\n
          \n
        1. Send the response body using a readable stream.<\/li>\n<\/ol>\n
          const<\/span> http = require<\/span>('http'<\/span>);\r\nconst<\/span> fs = require<\/span>('fs'<\/span>);\r\n\r\nconst<\/span> server = http.createServer<\/span>((req, res<\/span>) =><\/span> {\r\n  const<\/span> readableStream = fs.createReadStream<\/span>('file.txt'<\/span>);\r\n  res.end<\/span>(readableStream);\r\n});\r\n\r\nserver.listen<\/span>(3000<\/span>);\r\n<\/code><\/pre>\n
          Points to note:<\/p>\n
            \n
          1. The method http.response.end() can only be called once in the response handling function; calling it multiple times will result in an exception.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
