How to get a json file in express js and display in view

var fs = require("fs"),
    json;

function readJsonFileSync(filepath, encoding){

    if (typeof (encoding) == 'undefined'){
        encoding = 'utf8';
    }
    var file = fs.readFileSync(filepath, encoding);
    return JSON.parse(file);
}

function getConfig(file){

    var filepath = __dirname + '/' + file;
    return readJsonFileSync(filepath);
}

//assume that config.json is in application root

json = getConfig('config.json');

This one worked for me. Using fs module:

var fs = require('fs');

function readJSONFile(filename, callback) {
  fs.readFile(filename, function (err, data) {
    if(err) {
      callback(err);
      return;
    }
    try {
      callback(null, JSON.parse(data));
    } catch(exception) {
      callback(exception);
    }
  });
}

Usage:

readJSONFile('../../data.json', function (err, json) {
  if(err) { throw err; }
  console.log(json);
});
