I did a login page. If user enters email and password then user can enter the site. But I add a jsw file to access the collection. jsw file works fine. When I invoke the function from jsw file in login page, I cannot get the result.
I tried different ways. For example;

  1. login(email, password)
    .then(function(result) {
    if (result === true)
  2. login(email, password)
    .then(result {
    if (result === true)
  3. let isSuccessful : login(email, password);
    But still does not work

What are you actually trying to accomplish with your additional backend jsw file?

Could you not use something already setup with the Wix Users Backend?

the function returns boolean value. But I can not get this value from login page .
You can see the return keyword.

This is my jsw file content:

import wixData from ‘wix-data’;

export function login(email, password) {

let isSuccessful = false ;
wixData.query(“AccessRightToSite”)
.eq(“email”, email)
.eq(“password”, password)
.find()
.then((result) => {
if (result.items.length === 1)
{
console.log(“Yes”);
return true ;
}
else
{
console.log(“No”);
return false ;
}
});
}

This is my login page : If you look to response side below, I don’t know the reason but response is null or undefined

import wixLocation from ‘wix-location’;
import wixWindow from ‘wix-window’;
import { login } from ‘backend/security’;
import { session } from ‘wix-storage’;

$w.onReady( function () {
//TODO: write your page related code here…
});

export function btnLogin_click(event) {
let email = $w(“#txtEmail”).value;
let password = $w(“#txtPassword”).value;

login(email, password) 
    .then((response) => { 
        console.log(response);

if (response === true )
{
wixLocation.to(‘/homepage’);
session.setItem(“email”, email);
session.setItem(“password”, password);
console.log(session);
console.log(“successful”)
}
else
{
console.log(“warning”)
wixWindow.openLightbox(“WarningMessage”);
}
})
}

//backend code

function functionName(a,b)
{
    return wixData.query("database")
    .eq("a", a)
    .eq("b", b)
    .find()
    .then((res) => {
        return (res)
    })
}

I think you forgot the return before wixData
