Optimize Bundle Size and Load | Dataford Interview Questions

Demonstrate how you would optimize a web application to reduce bundle size and improve load times.

Implement the dependency analysis described below. Given modules with sizes and dependencies, compute the initial bundle, shared lazy modules, each route's lazy chunk, and the resulting sizes. A module belongs in the shared chunk when at least two lazy routes require it, unless it is already in the initial bundle. Return module names in sorted order.

Constraints

1 <= len(modules) <= 1000
Module names are unique strings
Every dependency and entry refers to a listed module
Dependencies form a directed acyclic graph
Module sizes are nonnegative integers
initial_entries contains at least one module
lazy_entries maps unique route names to one entry module

Function Signature

def optimize_bundles(modules, initial_entries, lazy_entries):
