Pagination and Search

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
