Installation

Bundling

This module is distributed in 3 formats

• commonjs build dist/torus.cjs.js in es5 format
• umd build dist/torus.umd.min.js in es5 format without polyfilling corejs minified
• umd build dist/torus.polyfill.umd.min.js in es5 format with polyfilling corejs minified

By default, the appropriate format is used for your specified usecase You can use a different format (if you know what you're doing) by referencing the correct file

The cjs build is not polyfilled with core-js. It is upto the user to polyfill based on the browserlist they target

Tips for NUXT

This is a plugin that works only on the client side. So please register it as a ssr-free plugin.

Usage

Please refer to the examples folder for details on usage using dynamic import.

Rehydration

Torus uses window.sessionStorage to store user details.

So, if the user reloads the page, all his data would be rehydrated and the user doesn't need to log in.

The samples provided in the examples folder illustrate the above case.
