Part 8 of this project

Preferences

Persist theme and font size in a prefs JSON file

Goal for this part

Persist theme and font size in a prefs JSON file.

Treat 08-Preferences 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 Electron experience for part 1. Later parts assume you finished the earlier snapshots on the same machine.

  • Node.js is installed so you can run npm install
  • You are comfortable editing JavaScript and HTML files

Why Electron fits Inkline

Electron is how many shipping editors wrap Chromium and Node. You get a desktop window with web UI and file-system access from the main process.

A textarea, tab strip, and menu bar map cleanly to HTML. Keep file I/O in main/preload—never trust the renderer with raw paths unchecked.

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:

fs.writeFileSync(filePath, contents, "utf8");

How to run it

Clone the teaching repo, open 08-Preferences, install what the README asks for, then run npx electron ..

git clone https://github.com/michaeldunga1/fcc-electron-editor.git
cd fcc-electron-editor/08-Preferences
npm install
npx electron .

Common mistakes

  • Ignoring platform-specific install notes in the snapshot README
  • Persisting preferences without a defaults fallback
  • Storing secrets in plain text beside the app
  • Forgetting to reload prefs after a restart
