Mini Router: Dispatch Any Request
Build the request router that maps a path like /users/42 to the right handler, the core idea inside Flask, Django, and every web framework you have ever used.
What you'll be able to build
Build the request router that maps a path like /users/42 to the right handler, the core idea inside Flask, Django, and every web framework you have ever used. Along the way you pick up real, transferable Python skills, not just this one project:
- dicts as a route table (path to handler)
- the re module to match paths and capture params
- functions as route handlers
- if/elif dispatch on the HTTP method
- assembling a JSON-ready response dict
- a default 404 fallback

Yours is built from your own placement, so module count and depth will differ. This map shows what a intermediate-level Python learner building Mini Router actually gets.
- Module 1: Values and output5 lessons
Builds the script for your Mini Router.
- Module 2: Collections and data5 lessons
Builds the data flow workflow for your Mini Router.
- Module 3: Branching and state5 lessons
Builds the function that powers your Mini Router.
- Module 4: Functions and tests5 lessons
Builds the reusable module for your Mini Router.
- Module 5: Files, APIs, and persistence5 lessons
Builds the service boundary for your Mini Router.
- Module 6: Packaging and review3 lessons
Builds the release package for your Mini Router.
How the lessons actually work
Every lesson has you predict what a piece of Python code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Mini Router, and a runnable proof page tied to your own code.
Common questions
How long does the Mini Router: Dispatch Any Request course take?
about 7 hours, across 6 modules and 28 lessons, at roughly 15 minutes per lesson. Your own course may run shorter or longer, since it's sized to your placement result, not a fixed template.
Do I need experience?
Some. This is an intermediate-tier Python project, so it assumes you're comfortable with Python basics and pushes past them.
How much does it cost?
$15 one-time, no subscription. The first module is free, so you can see exactly how the course teaches before you pay for the rest.
