Enhanced user experience by incorporating essential blogging functionality such as markdown formatting, tagging, and QR code sharing. Author Huaiyu Khaw Initial work - Zest (GitHub) Released on Vercel Connect with me on LinkedIn Showcase This project was designed to demonstrate: Use of React, Remix, Typescript and TailwindCSS to build a modern and responsive user interface. Implementation of server-side rendering with Next.js for improved performance and search engine optimization. Proper form validation by using Zod Usage example The usage of LinkBio is straightforward: users simply create an account and customize their link in bio with their preferred links. Once they're done, they can share their link in bio with their audience, making it easier for them to find and connect with them.

Fork it, change it, and use npx create-remix --template your/repo! Make it your own. Quickstart Click this button to create a Gitpod workspace with the project set up and Fly pre-installed Gitpod Ready-to-Code Development This step only applies if you've opted out of having the CLI install dependencies for you: npx remix init Initial setup: If you just generated this project, this step has been done for you. npm run setup Start dev server: npm run dev This starts your app in development mode, rebuilding assets on file changes. The database seed script creates a new user with some data you can use to get started: Email: rachel@remix.run Password: racheliscool Relevant code: This is a pretty simple note-taking app, but it's a good example of how you can build a full stack app with Prisma and Remix. The main functionality is creating users, logging in and out, and creating and deleting notes. creating users, and logging in and out ./app/models/user.server.ts user sessions, and verifying them ./app/session.server.ts creating, and deleting notes ./app/models/note.server.ts Deployment This Remix Stack comes with two GitHub Actions that handle automatically deploying your app to production and staging environments. Prior to your first deployment, you'll need to do a few things: Install Fly Sign up and log in to Fly fly auth signup Note: If you have more than one Fly account, ensure that you are signed into the same account in the Fly CLI as you are in the browser. In your terminal, run fly auth whoami and ensure the email matches the Fly account signed into the browser. Create two apps on Fly, one for staging and one for production: fly apps create zest-f716 fly apps create zest-f716-staging Note: Make sure this name matches the app set in your fly.toml file. Otherwise, you will not be able to deploy. Initialize Git. git init Create a new GitHub Repository, and then add it as the remote for your project. Do not push your app yet! git remote add origin Add a FLY_API_TOKEN to your GitHub repo. To do this, go to your user settings on Fly and create a new token, then add it to your repo secrets with the name FLY_API_TOKEN. Add a SESSION_SECRET to your fly app secrets, to do this you can run the following commands: fly secrets set SESSION_SECRET=$(openssl rand -hex 32) --app zest-f716 fly secrets set SESSION_SECRET=$(openssl rand -hex 32) --app zest-f716-staging If you don't have openssl installed, you can also use 1password to generate a random secret, just replace $(openssl rand -hex 32) with the generated secret. Create a persistent volume for the sqlite database for both your staging and production environments. Run the following: fly volumes create data --size 1 --app zest-f716 fly volumes create data --size 1 --app zest-f716-staging Now that everything is set up you can commit and push your changes to your repo. Every commit to your main branch will trigger a deployment to your production environment, and every commit to your dev branch will trigger a deployment to your staging environment. Connecting to your database The sqlite database lives at /data/sqlite.db in your deployed application. You can connect to the live database by running fly ssh console -C database-cli. Getting Help with Deployment If you run into any issues deploying to Fly, make sure you've followed all of the steps above and if you have, then post as many details about your deployment (including your app name) to the Fly support community. They're normally pretty responsive over there and hopefully can help resolve any of your deployment issues and questions. GitHub Actions We use GitHub Actions for continuous integration and deployment. Anything that gets into the main branch will be deployed to production after running tests/build/etc. Anything in the dev branch will be deployed to staging. Testing Cypress We use Cypress for our End-to-End tests in this project. You'll find those in the cypress directory. As you make changes, add to an existing file or create a new file in the cypress/e2e directory to test your changes. We use @testing-library/cypress for selecting elements on the page semantically. To run these tests in development, run npm run test:e2e:dev which will start the dev server for the app as well as the Cypress client. Make sure the database is running in docker as described above. We have a utility for testing authenticated features without having to go through the login flow: cy.login(); // you are now logged in as a new user We also have a utility to auto-delete the user at the end of your test. Just make sure to add this in each test file: afterEach(() => { cy.cleanupUser(); }); That way, we can keep your local db clean and keep your tests isolated from one another. Vitest For lower level tests of utilities and individual components, we use vitest. We have DOM-specific assertion helpers via @testing-library/jest-dom. Type Checking This project uses TypeScript. It's recommended to get TypeScript set up for your editor to get a really great in-editor experience with type checking and auto-complete. To run type checking across the whole project, run npm run typecheck. Linting This project uses ESLint for linting. That is configured in .eslintrc.js. Formatting We use Prettier for auto-formatting in this project. It's recommended to install an editor plugin (like the VSCode Prettier plugin) to get auto-formatting on save. There's also a npm run format script you can run to format all files in the project.

LastQR

Create QR menus for your restaurant. Try it! lastqr.huaiyukhaw.com LastQR is a web-based application that allows restaurant customers to access menus via QR codes. The app was developed using modern web technologies, including React, Next.js, TailwindCSS, and Supabase. Author Huaiyu Khaw Initial work - LastQR (GitHub) Released on Vercel My professional profile on LinkedIn Showcase This project was designed to demonstrate: Use of React with Typescript and TailwindCSS to build a modern and responsive user interface. Utilization of a variety of libraies, such as @shortcm/qr-image for QR code generation and React Hot Toast for notifications. Implementation of asynchronous programming techniques to fetch and manipulate data from a backend-as-a-service platform. LastQR is a web-based application that allows restaurant customers to access menus via QR codes. The app was developed using modern web technologies, including React, Next.js, TailwindCSS, and Supabase. The front-end of the app was built using React, which provides a component-based architecture for building user interfaces. I used Next.js as the framework to support server-side rendering, which improves the app's performance and search engine optimization. To design the app's user interface, I used TailwindCSS, a utility-first CSS framework that provides pre-built styles and classes for rapid development. The app's functionality was implemented using React's state management and lifecycle methods, which provides interactivity and logic to the user interface. Specifically, the app uses React hooks to handle QR code scanning, API requests, and menu item selection. To ensure that the app is fast and responsive, I used asynchronous programming techniques, such as Promises and async/await, to handle API requests and prevent blocking the user interface. To fetch menu data from the back-end, the app uses Supabase, a backend-as-a-service platform that provides a PostgreSQL database and API. During the development process, I used several development tools and libraries to improve my productivity and code quality. For example, I used Visual Studio Code as my code editor, and Git for version control. Additionally, I used a variety of libraries, including @shortcm/qr-image for QR code generation, and React Hot Toast for notifications. Usage example The usage of the QR Menu App is straightforward: diners simply scan the QR code using their smartphone's camera, and the app will take them to the restaurant's digital menu. From there, they can browse through the items, without the need for physical menus. This makes the dining experience more convenient and efficient, especially during busy hours.
