Part 3 of this project

Layout and UI

Render Handlebars pages with Bootstrap 5.

Goal

This snapshot advances Circuit Daily by teaching you to render Handlebars pages with Bootstrap 5.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use Node.js 20+, npm, and a terminal. You should recognize TypeScript modules, decorators, and HTTP verbs.

Port 3001 must be free. Copy .env.example before starting database stages.

  • Node.js and npm
  • A code editor and terminal
  • Docker from part 4 onward

Concepts

Handlebars escapes values by default. Shared layouts keep navigation consistent; Bootstrap provides readable defaults.

Keep controllers thin: accept input, call services, render Handlebars views. Escape stays on by default in templates.

Walkthrough

Configure the Express view engine, pass sample posts to home, and extend a base layout.

Read the example, then open the matching snapshot. The repository includes the surrounding setup and error handling.

res.render('home', { title: 'Home', posts: SAMPLE });

Run and verify

Enter 03-Layout-And-UI, install dependencies, copy .env.example when present, and start Nest on port 3001.

Open http://127.0.0.1:3001. Watch the terminal for validation and database errors.

git clone https://github.com/michaeldunga1/fcc-nestjs-blog.git
cd fcc-nestjs-blog/03-Layout-And-UI
npm install
cp .env.example .env
npm run start:dev

Troubleshooting

Missing view errors mean the views path is wrong relative to the Nest dist/src layout.

Missing-module errors usually mean npm install ran in another snapshot. For Postgres failures, confirm Docker and the circuit_NN database name.

  • Read the first error first
  • Restart after environment changes
  • Never commit .env or node_modules

Try this

Render a friendly empty state when the posts list is empty.

Test a happy path and one invalid or unauthorized request.

  • Make one small change
  • Test it in the browser
  • Compare with the next snapshot only after it works
