I would appreciate a direction as I am lost and cannot find any source that explains how I can create a global function that my customers can use. I have multiple REST API that customers can use however I am trying to create a javascrtipt SDK so they can simply call a function and everything else is taken care of.
For example, all the user has to do is import a script in head tag and then use my variable across the app to invoke functions. Like how stripe provides SDK.
Stripe.getCustomer('pass some data id');
I have a similar need, where user can save data to DB.
myapp.saveDatatoDb(data).then(response => {
});
the saveToDB will take care of calling an API and storing the information. Where do I get started?
