Firebase Functions Typescript - Sending Emails with html templates

I am trying to read html file with fs.readFile('../emailTemplates/template.html') from index.ts

my folders :


from index.ts :

import * as UsersFunctions from './UsersFunctions/UsersFunctions';
export const newUserRegister = UsersFunctions.onCreateNewUser;

from UsersFunctions.ts

 export const onCreateNewUser = functions.firestore.document('users/allUsers/usersData/{userId}').onCreate(async (snap, context) => {
  fs.readFile("../emailTemplates/template.html", {encoding: 'utf-8'}, (err, html) => {
    if (err) {

    else {


i am getting an error from firebase functions :

Error: ENOENT: no such file or directory, open '../emailTemplates/template.html'
at Error (native)
errno: -2,
code: 'ENOENT',
syscall: 'open',
path: 'user_code/lib/emailTemplates/newUserRegisterHtmlTemplate.html'

    The problem is that your path to the template doesn't match your project files organization. I suggest that you only put TypeScript source code in src and put all other files you want to read and write under your functions folder at the same level as src. So, you could organize your files like this:

            /other source files

    Then, in index.ts, you could read template.html using the same path ../emailTemplates/template.html.
