Customize map output in node JS

Question

As I have 4 key/value in map , I'm trying to store two keys in string format and rest two in an array but it's not taking array's multiple value.

right now what output I'm getting :

{ url: 'account/43',    
  status: '200',    
  headers: [ '\'content-type\' = \'application/json\'' ],    
  body: [ '{ "name": "Fatma Zaman" }' ]}

Expected output:

{ url: 'account/43',
  status: '200' ,
  headers: 
     [ 'content-type = application/json',  
       'content-type = application/text' ], 
  body: [ '{ name: Fatma Zaman }' ] }

below are the code which is returning either multiple headers value but all keys are in array format or url/status in string & headers/body in array.

 function processFile(content) {

    content.forEach(function(node) {

        if (node.startsWith("//")) {

            key = node.substring(2, node.length-2).toLowerCase().trim()

            return

        } else {

            value = node

        }       

        if (key in map) {

            map[key].push(value)

        } else {

            map[key]= [value]

        }

        map[key] = ["headers", "body"].includes(key)? [value] : value

     })

    return map

  }

if I add below code , it's giving me multiple value but not url/body not in string

        if (key in map) { 

      map[key].push(value) 

  } else { 

      map[key]= [value] 
  }

In short , I'm not able to achieve both at the same time. like multiple header value with url/status in string format. Any help and suggestion would be appreciate it

Here is the full code

const fs = require("fs")

const path = require("path")

let key

let value

let filePath

function parseFile(filePath) {

    filePath = path.join(__dirname, "../resources/FileData1.txt")

    fs.readFile(filePath, function(err, data) {

        if (err) throw err

        content = data.toString().split(/(?:\r\n|\r|\n)/g).map(function(line) {

            return line.trim()

        }).filter(Boolean)

        console.log(processFile(content))

    })

}

function processFile(content) {

    content.forEach(function(node) {

        if (node.startsWith("//")) {

            key = node.substring(2, node.length-2).toLowerCase().trim()

            return

        } else {

            value = node

        }

        if  (key in map) {

            map[key].push(value)

        } else {

            map[key] = value

        }

        // map[key] = ["headers", "body"].includes(key)? [value] : value



    })

    return map

}

parseFile(filePath)

module.exports = {parseFile, processFile}

And input are in below format:

//Status//

200


//HEADERS//

content-type = application/json


//BODY//

{ name: Fatma Zaman }


//URL//

account/43


//HEADERS//

content-type = application/text

I don't see a Map in your code. What you have a plain JavaScript object. — Jordan Running

Please try the below code:

function processFile(content) {
let map ={};
content.forEach(function(node) {

    if (node.startsWith("//")) {

        key = node.substring(2, node.length-2).toLowerCase().trim()

        return

    } else {

        value = node

    }       

    if (["headers", "body"].includes(key)) {
        if(map[key]){
            map[key].push(value);
        }else{
            map[key] = [value]
        }
    } else {
        map[key]= value
    }
 })

return map 
}

This should work now, I have tested with the input. Kindly check and confirm :)

I'm getting below error with above solution: ERROR map[key].push(value) ^ TypeError: map[key].push is not a function

DHIRAJ KATEKAR Over a year ago

Try now I have declared map variable

Fatma Zaman Over a year ago

Oh I already have map variable declared globally , even if tried declaring variable inside function unfortunately the error is still same :-(

I don't sure what you want, but i think this code will help you:

var yourObj = {
    url: 'account/43',
    status: '200',
    headers: ['\'content-type\' = \'application/json\''],
    body: ['{ "name": "Fatma Zaman" }']
};

console.log('Your obj:');
console.log(yourObj);

console.log('formatted:');
console.log(format(yourObj));


function format(obj) {
    for (var prop in obj) {
        if (typeof obj[prop] != 'object') {
            obj[prop] = obj[prop].replace(/"|'/g, '');
        } else {
            obj[prop] = format(obj[prop]);
        }
    }
    return obj;
}

I hope it can help you.

your solution does make sense but unfortunately It's not taking multiple value of headers :-(
