Requirements

The language code given in the link are used for translation purpose Supported Languages for translations

For development, you will only need Node.js and a node global package, Npm, installed in your environement.

Installation

• Node, Mongodb installation on Windows

  1. Just go on official Node.js website and download the installer. Also, be sure to have git available in your PATH, npm might need it (You can find git here).
  2. You can find more information about the installation on the official Mongodb website.
  3. You can find more information about the installation on the official Mongodb Compass website.

  To install express js compass, just run the following commonds.

  npm install express
  

You can install nodejs, npm and mongodb by visiting the links given above.

• Node, Mongodb installation on Ubuntu

  You can install nodejs, npm and mongodb, expressjs easily with apt install, just run the following commands.

  $ sudo apt install nodejs
  $ sudo apt install npm
  $ sudo apt install mongodb-org
  

  To install mongodb compass, just run the following commonds.

  1. Download MongoDB Compass

     wget https://downloads.mongodb.com/compass/mongodb-compass_1.26.1_amd64.deb

  2. Install MongoDB Compass

     sudo dpkg -i mongodb-compass_1.26.1_amd64.deb

  3. Start MongoDB Compass

     mongodb-compass

  To install express js compass, just run the following commonds.

  npm install express
  

If the installation was successful, you should be able to run the following command.

$ node --version
v14.15.3

$ npm --version
6.14.9

4.4.6

If you need to update npm, you can make it using npm! Cool right? After running the following command, just open again the command line and be happy.

$ npm install npm -g

Install

$ git clone https://github.com/rishabh15b/TextTranslationApi.git
$ cd TextTranslationApi
$ npm install

Install some dev dependencies

1. async by the given commond.
    npm i async      
2. nodemon by given below commond.
    npm install --save-dev nodemon

Running the project

-- nodemon server.js and must be running on localhost:3000 // server.js because it is mentioned in as my start file in scripts which is in package.json file and it is the main file.

-- mongodb server mast be running on 27017 PORT.

• Design of the Project

1. Before starting any Node.js project we should run npm init to create a new package.json file for our project. Doing this we have to anwer few basic question to start developing pour project.

2. Then we install express js to start writing our web application.

3. Now I made a new file named server.js to start writing my simple express application for text-transalation in which i imported create server form http, configured a PORT number using which on my web brower i will run my project.

4. Made a new file app.js which i imported in my main server.js file. Now in my app.js file I imported express and the code that i wrote was to give the response if any error comes while running the server when requesting data from server.

5. Now I made two new files:

   One conn.js in which i configured my mongodb connection to store all my data whcih is a No-Sql type database and used mongodb compass to see all my database. Imported stored.js file in conn.js.

   Second stored.js in whcih I worked on my data schema, to show what all data willbe asked and will be stored in my database.

6. Now I made a new file text.js in which i started working on my text-transaltion-api, I used @vitalets/google-translate-api for my real text translation. Imported my conn.js. Now used HTTP method POST which is used to send data to a server to create/update a resource and used async that permits other processing to continue before the transmission has finished.

• Approach and Solution towards the problem given:

-- My approach towards this project was to take the languages, text from the user and translate in to the given language and then store it into my database. Now if any other person wants the same translation so he has not to again translate if the same text and language is there in my database it will show the translated text and will not push it again.

-- So to solve this problem I declared a empty list first, then run a loop from 0 to language length so that text can we translated for each language given which was in the form of array. Then declared a variable in whcih I used my transalate function which i declared before in whcih I passed my two parameters text and language. Now declared a new variable in which my translated text for every language and to store in in my databse i used user.save() commond. This code was functioal, now if we had to check if the text and language is stored in datbase so I declated a new variable in which i used db.findOne() commond. After all this i passed status.send commond and showed the translation in the form of json file.

• Testing of Project

  I used POSTMAN to test all my POST request. In postman at the place of Enter request URL type localhost:3000/text and select POST. Then choosing raw as json write the text and language for the translated text and then click on send.

  try { var list = [] for (var i = 0; i < req.body.lang.length; i++) {

        const fill = await Stored.findOne({
            text: req.body.text,
            lang: req.body.lang[i]
        })           
        if (!fill) {
            const r = await translate(req.body.text, { to: req.body.lang[i] });
  
            console.log(r.text);
            list.push(r.text);
  
            const user = new Stored({ text: req.body.text, lang: req.body.lang[i], translatedText: r.text });
            await user.save()
        }
        else{
            list.push(fill.translatedText)               
        }
    }
    res.status(201).send({
        text: req.body.text,
        translatedtext: list,
        language: req.body.lang
    });
  

  }

  Screenshots are given of testing done on POSTMAN and database are all at starting of readme.
