Pagination and Search

Paginate the feed and search post text.

Goal

This snapshot advances Beaconrock Digest 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 Docker for Postgres stages.

Port 3005 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

Page size 5. Search filters before paginating.

Keep the server boundary visible: routeLoader$ reads trusted data; routeAction$ validates input and re-checks authorization before mutations.

Walkthrough

Accept q and page query params in the loader.

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 Qwik City on port 3005.

Open http://127.0.0.1:3005. Watch the terminal for validation and database errors.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-qwik-blog.git
cd fcc-qwik-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, confirm Docker is running and the beaconrock_NN name matches the snapshot. Never commit .env 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
