How to create an external widget for a Laravel + VueJS project like live chats, flight search widgets and other similar services?

Question

Laravel

Tell me what to read and in which direction to dig for the next task:
There is a project, in other words, a calculator for calculating prices for some products. Companies register on the site, enter their price lists for components and the calculator calculates the final price. The task is to make it possible for companies to insert the code of my calculator on their website and make calculations already on their sites with the data of their customers, but with filtering only for a specific company and changing styles. Tell me what to read on this topic and in which direction to dig to implement this task?

Answer 1

Make up a form, describe the logic in js that will communicate with your backend so that it can be configured through the config
What a third-party project is written on, especially its backend, does not play a role.
It will come out approximately like Google captcha or GTM, they inserted a short script tag on the site that will load all your code, and it will display a widget on the site
. There seems to be nothing specific to write literature on this topic specifically.
