Pagination and Search

Paginate the feed and search post text.

Goal

This snapshot advances Glasspoint Notes by teaching you to paginate the feed and search post text.

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. No Docker is required — each snapshot uses a local SQLite file.

Port 3006 must be free. Copy .env.example before starting database stages.

  • Node.js and npm
  • A code editor and terminal

Concepts

Page size 5. Search filters before paginating.

Keep handlers thin: Express routes load data, Lit templates present escaped HTML, and mutations re-check authorization on the server.

Walkthrough

Accept q and page query params.

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

const pageSize = 5
const offset = (page - 1) * pageSize

Run and verify

Enter 10-Pagination-And-Search, install dependencies, copy .env.example, and start Express on port 3006.

Open http://127.0.0.1:3006. Watch the terminal for validation and database errors.

git clone https://github.com/michaeldunga1/fcc-lit-blog.git
cd fcc-lit-blog/10-Pagination-And-Search
npm install
cp .env.example .env
npm run dev

Troubleshooting

Off-by-one often comes from mixing 0-based offsets with 1-based pages.

For database failures, delete glasspoint.db and restart so schema and seeds recreate. Never commit .env, *.db, or node_modules.

  • Read the first error first
  • Restart after environment changes
  • Never commit secrets

Try this

Search for ownership and confirm matching cards.

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
