JSON response in clientSide NodeJs

Question

I want to get a .json file from server to .js file in ClientSide

var fs = require('fs');
var bodyParser = require('body-parser');
var urlencodedParser = bodyParser.urlencoded({extended: false, limit: '50mb'});
module.exports = function(app){
  app.get('/tables_particular/', function(req, res){

    first = JSON.parse(fs.readFileSync('./database/table.json'))

    res.render('tables_particular', {todos: data.member, 
                                     tbledit: first,
                            });
});

app.post('/tables_particular/', urlencodedParser, function(req, res){

    var exportlist = req.body.detail

    fs.writeFileSync('./database/table.json', exportlist); 
        res.json(exportlist);

});

and here is the app.js: (server code)

var express = require('express');

var mShController = require('./controllers/mShController');

var app = express();

//
app.set('view engine', 'ejs');

//static files
app.use(express.static('./public'));

mShController(app);


//listen to port
app.listen(3000);
console.log('You are listening to port 3000');

what is the code I need to use in javascript file to get the json file.

I need it in js file:

var data = response.tbledit

If `myfile.json` is static, you can just `const json = require('myfile.json')` — Nick Tomlin, Oct 07 '17 at 20:50

var content;  
var fs = require('fs');
fs.readFile('path/myfile.json', function read(err, data) {
    if (err) {
        throw err;
    }
    content = data;

    console.log(content); // HERE DO ANYTHING WITH THE JSON DATA
});

OR See this link read-json-file-content-with-require-vs-fs-readfile

var myObj = require('path/myfile');
var value = myObj.someValue;
});

but i don't need to change extension of file... i need to use the json file dynamically in javascript file to show it in a table – jalala alalia Oct 07 '17 at 20:33
you have to add fs npm package. – Sudhanshu Gaur Oct 07 '17 at 20:47
use 'fs' package. – Sudhanshu Gaur Oct 07 '17 at 20:49
i use 'fs'.. but it work just in app.js (in server) not in Browser ( i mean : fs can't define in javascript file which work for html page).. i hope that i good explain – jalala alalia Oct 07 '17 at 20:55
In Browser in response you can simple access it by using `response.tbledit'`because when you send json data from server to client then it didn't come as a file(it came as a JSON Data). – Sudhanshu Gaur Oct 07 '17 at 20:58
Like from my code var `myObj` is a JSON data not a json file so you can directly catch it like response.myObj – Sudhanshu Gaur Oct 07 '17 at 20:59
response is not defined... and the same when i use : this.response.tbledit (tbledit not defined) – jalala alalia Oct 07 '17 at 21:06
var fs = require('fs'); var bodyParser = require('body-parser'); var urlencodedParser = bodyParser.urlencoded({extended: false, limit: '50mb'}); – jalala alalia Oct 07 '17 at 21:14
where is response defined ?? (show me clientside code where you will be parsing your response) – Sudhanshu Gaur Oct 07 '17 at 21:16
