Pagination and Search

Paginate the feed and search post text.

Goal

This snapshot advances Saltmarsh Daily 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 Deno 2+ and a code editor. No Docker is required — each snapshot uses its own SQLite file.

Port 8003 must be free. Copy .env.example before starting database stages.

  • Deno runtime
  • A code editor and terminal

Concepts

Page size 5. Search filters before paginating.

Keep handlers thin: routes present data, server logic enforces rules, and Fresh escapes JSX output by default.

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 deps, copy .env.example, and start Fresh on port 8003.

Open http://127.0.0.1:8003. Watch the terminal for validation and database errors.

git clone https://github.com/michaeldunga1/fcc-fresh-blog.git
cd fcc-fresh-blog/10-Pagination-And-Search
deno install
cp .env.example .env
deno task start

Troubleshooting

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

For SQLite failures, confirm DATABASE_PATH and write permissions. Never commit .env or the .db file.

  • 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
