[Feature Request]: Integration of mailing templates for authentication

[aditya-garg-09-01-2002]

Is your feature request related to a problem? Please describe.

• Currently, we are sending out authentication mails, containing only OTP nothing else, making sub-standard offerings.
• We need to integrate these templates so that mail goes with data in a formatted manner.

Describe the solution you'd like

• [x] In the src/utils/dataFormat.ts file, create a new function hbsToHtml() which
  • takes input as .hbs template filename and the variable data to be replaced in the template.
  • variable data can be taken in as an object and provided to handlebars later.
  • we will be overlooking integration of the logo for the scope of this issue, we will be doing that later.
  • returns the compiled HTML using handlebars.
  • following can be used as a reference

      const rawHTML=await promises.readFile(__dirname+"/../../assets/"+fileName,{encoding:"utf-8"});
      let template=Handlebars.compile(rawHTML)
      return template(replacements);

• [x] Now move to src/utils/communication.ts, where we will be integrating the templates actually
  • reach out to sendOtp function, we need to add an argument for name of user as well here.
  • we will provide this name to mailOtp & messageOtp function, updating their function definition as well.
  • in mailOtp function we can see a function sendMail() been called, with 3 arguments, third one been the actual HTML been sent.
  • in here we will replace the <div>${otpHash}<div>, with the HTML as output from the hbsToHtml function.
  • in the functions, sendOtp, mailOtp, messageOtp, we can see otpHash is the argument instead of otp, as we are sending otp and not its hash, so kindly update it as well.
• [x] Updating function definition for sendOtp will cause need of changes in the following file as well
  • src/controllers/user/resendOtp - do provide necessary inputs like name, otp and template file name
  • src/controllers/user/registerUser - do provide necessary inputs like name, otp and template file name
  • integration of template of forgot password will take place at a later point, first the controller will need an update alltogether.
