How to send a POST request from a function in my Frontend JS file in my NodeJS web app? [duplicate]

Question

Lets say i have two variables in my NodeJS front end Example.js file:

var a; var b; function senddata() { a = "Hassan"; b = 7; } return true;

Now what i'd like to do is send these two variables to my server using a POST request. At the backend i'm using ExpressJS for my routes.

In my Routes.js(At the backend) i want to receive the values of a and b through a POST request from my senddata() function.

In my routes i have created this route for the data:

router.post('/save', function (req, res, next) { //Sending values of a and b to my database });

If you have NodeJs on the front-end too. I would suggest to use a http client, like Axios

Then you can use it this way:

const axios = require('axios'); function senddata() { axios.post('/save', { a: 'Hassan', b: 7 }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); }); }
