data-binder v2.0.4
The Objective is to enable dynamic data binding to web content to send as response .
Overview
All dynamic data can be added to file/response by mapping the required data to variable. All variables should be declared inside curly braces preceeded by $ in source file.
Input data(index.html) : <html> <head> <head> <body> <span>Hi, ${name} here.<span> <body> </html>
Expected output(indexTemp.html) : <html> <head> <head> <body> <span>Hi, Naveen here.<span> <body> </html>
Available methods are as follows :
Method 1: To achieve data binding and to get result back in given destination file.
'use strict' dataBinder = require('data-binder'); var dataArray = [] //Array should be created to add dynamic data and respective keys
dataArray'name' = "Naveen" //The dynamic data "Naveen" is attached to variable "name" / method signature : bindToDestinationFile(sourceFilePath, dynamicDataArray, destinationFilePath, callback(optional)) this method will binds data and then reflects the required data in destination file. / dataBinder.bindToDestinationFile("./index.html",dataArray, "./indexTemp.html")
Method 2: To achieve data binding and to pipe data into given WriteStream.
'use strict' var fs = require('fs'), path = require('path'), dataBinder = require('data-binder'); var dataArray = [] dataArray'name' = "Naveen" / method signature : bindToWriteStream (sourceFilePath, dynamicDataArray, destinationWriteStream, callback(optional)) this method will binds data and pipe the required data into destination WriteStream. / var destinationWriteStream = fs.createWriteStream(path.normalize("./indexTemp.html")) dataBinder.bindToWriteStream ("./index.html", dataArray, destinationWriteStream)
Method 3: To achieve data binding and to pipe data into given Response object.
'use strict'
var dataBinder = require('data-binder'); var dataArray = [] dataArray'name' = "Naveen" / method signature : bindToResponse (sourceFilePath, dynamicDataArray, response, callback(can be used to handle errors)) this method will binds data and pipe the required data into response / dataBinder.bindToResponse ("./index.html", dataArray, response)
Method 4: To achieve data binding and to pipe data into given Response object with custom header object.
'use strict'
var dataBinder = require('data-binder'); var dataArray = [], responseHeader = {} dataArray'name' = "Naveen" responseHeader = { 'Content-Type' : 'text/html; charset=utf-8', 'X-Content-Type-Options': 'nosniff', 'Cache-Control' : 'public, max-age=3600, no-transform, immutable', 'Content-Encoding': 'gzip', 'Vary' : 'Accept-Encoding', 'Strict-Transport-Security' : 'max-age=31536000; includeSubDomains', 'X-Frame-Options' : 'SAMEORIGIN', 'X-XSS-Protection' : '1; mode=block; report=localhost:1337/reports/security/log', 'ETag' : 'abcdef' } / method signature : bindToCustomOkResponse (sourceFilePath, dynamicDataArray, response, responseHeader, callback(can be used to handle errors)) this method will binds data and pipe the required data into response / dataBinder.bindToCustomOkResponse ("./index.html", dataArray, response, responseHeader, function(errMsg){ if(errMsg){ res.writeHead(401, "{'Content-Type' : 'text/html'}") res.end() } });
