Your Turn: Reading the Toolchain

This Is About Thinking, Not Building

You are not writing code in this exercise.

You are reading a setup and explaining what it does.

That’s a skill you will use constantly in the real world.

Exercise 1: Spot the Platform

Open a modern front-end project (React, Vue, Astro, etc.) and answer:

• What starts the dev server?
• Where does development begin?
• Is there a build step?
• When does bundling happen?

You don’t need to know every detail.

You need to know where the ground is.

Exercise 2: Identify the Model

Look for clues:

• Is there a dev server command?
• Are files served directly or processed first?
• Is there a clear separation between dev and build?

Then answer:

Is this project pipeline-based or platform-based?

Explain why.

Exercise 3: Legacy Literacy

Now imagine you open an older project and see:

• a gulpfile.js
• a dist/ folder
• many plugins wired together

Answer:

• What problems was this toolchain solving?
• Why was it reasonable at the time?
• What pain points might exist today?

Context matters.

Exercise 4: Reason Without Judgment

For each setup you inspect:

• avoid “this is bad”
• avoid “this is outdated”

Instead ask:

• what problem was this solving?
• what assumptions does it make?

That mindset keeps you effective.

What You Should Walk Away With

If you can:

• identify the tooling model
• explain why it exists
• predict its strengths and weaknesses

You’re doing it right.
