Part 3 of this project

Forms

Validate URLs before navigation

Goal for this part

Validate URLs before navigation.

Treat 03-Forms as the source of truth for this checkpoint. If your local tree drifted, re-clone that folder rather than mixing files from neighbors.

What you should already know

You do not need prior Tauri experience for part 1. Later parts assume you finished the earlier snapshots on the same machine.

  • Node.js and a Rust toolchain are available for full Tauri runs
  • You can open index.html alone if you only want a quick UI peek

Why Tauri fits Lookout

Tauri wraps a system webview with a Rust core—ideal for teaching browser chrome without shipping Chromium yourself.

Address bar, tabs strip, and webview live in HTML; navigation history stays in Rust or local storage.

Checkpoint

After you run the snapshot, you should recognize the behavior described in the goal—before you move on. If the window (or server) never appears, stop and fix the run steps.

Code shape

Snapshots stay small on purpose. Look for this kind of core call as you read the folder:

window.location.assign(url);

How to run it

Clone the teaching repo, open 03-Forms, install what the README asks for, then run npm run tauri dev.

git clone https://github.com/michaeldunga1/fcc-tauri-browser.git
cd fcc-tauri-browser/03-Forms
npm install
npm run tauri dev

Common mistakes

  • Ignoring platform-specific install notes in the snapshot README
  • Accepting empty or invalid input without a message
  • Validating only in the UI and never in the save path
  • Using placeholder text as if it were real data
