Pagination and Search

Goal

This snapshot advances Tidepool 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. You should recognize React components, TypeScript modules, and HTTP verbs.

Port 3004 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

Pagination bounds work per page. Search filters with case-insensitive title matching before counting and slicing.

Keep the server boundary visible: Remix loaders read trusted data on the server; actions must validate input and re-check authorization before mutations.

Walkthrough

Use page size 5, compute total pages, and accept a q query parameter.

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

const pageSize = 5
const pages = Math.max(1, Math.ceil(total / pageSize))

Run and verify

Enter 10-Pagination-And-Search, install dependencies, copy .env.example when present, and start Remix on port 3004.

Open http://127.0.0.1:3004. Watch the terminal for validation and database errors.

docker compose -f ../docker-compose.yml up -d
git clone https://github.com/michaeldunga1/fcc-remix-blog.git
cd fcc-remix-blog/10-Pagination-And-Search
npm install
cp .env.example .env
npm run db:push
npm run db:seed
npm run dev

Troubleshooting

Off-by-one errors often come from mixing 0-based offsets with 1-based page numbers.

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

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

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
