Questions

I can’t use Template7.registerHelper with Framework7 v4 Core with webpack!

app.js file

import Framework7, { Template7 } from "framework7/framework7.esm.bundle.js";

Template7.registerHelper('callHelper', function() {
 return 'Mensaje!';
});

const app = new Framework7({ options });

template7-helpers-list.js

module.exports = ['callHelper'];

my component file (index.f7.html)

    <template>
        <div class="page">
        <div class="page-context">
        <div class="block-title">{{ callHelper }}</div>
        </div>
        </div>        
</template>

But i can’t see “Mensaje!”.

Please help me

Helpers are functions and functions assume you will pass arguments there:

Template7.registerHelper('callHelper', function(name) {
  return `Hello ${name}!`;
});

And it must be called like: {{callHelper "John"}}
