Have you ever dreamt of building a web application that runs seamlessly, even without an internet connection? Well, let me introduce you to Remember, a modern offline todo web app that not only helps you stay organized but also serves as a fantastic learning tool for progressive web apps (PWA). Prepare to embark on a journey where we’ll explore the features, setup instructions, and some troubleshooting tips!

What is Remember?

Remember is a progressive modern offline todo web app that utilizes app shell architecture and IndexedDB, making it accessible even when you’re not connected to the internet. If you want to see it in action, you can check out the live demo hosted on Firebase. It’s not just a todo list; it’s your companion in productivity!

Getting Started with Remember

To dive into building Remember, you’ll need a few tools. The project is bootstrapped with Create React App. Here’s a brief primer on the libraries and technologies used:

The Big Ones

• React: A JavaScript library for building user interfaces.
• Redux: State management tool for JavaScript apps.
• Webpack (ES6): Module bundler for JavaScript applications.
• Firebase: Cloud platform for building and managing apps.

Supporting Libraries

• react-motion: Animation library using spring dynamics.
• redux-saga: Side-effects library for managing complex interactions.
• react-redux: Connects React to Redux.
• react-hammerjs: Wrapper around HammerJS for touch gestures.
• localforage: Wrapper library around IndexedDB for offline storage.
• classnames: Utility for conditional CSS classnames.
• color-string: Utility for color manipulations.
• shortid: Utility for generating unique IDs.
• sw-precache: Generates service worker boilerplate for caching.

Building and Running Remember

Before you can run the app, be sure to install all dependencies. Follow these commands in your project directory:

yarn

After that, you can use the following scripts:

• yarn start: Run the app in development mode.
• yarn run build: Build the app for production.
• yarn run build-offline: Build the app with offline capabilities.

Understanding the Code: An Analogy

Imagine building a house (Your PWA) where every room (Components) has specific furniture (UI elements) designed for its purpose. You also have a storage facility (IndexedDB) in the basement to store things you may not use often yet might need later. An app shell architecture lets you design the exterior of your house, which remains visible even as you change the interior layout. Just like how you can invite friends over or access portions of your home regardless of your surrounding environment, Remember allows you to access your todo list even when you’re offline!

Troubleshooting Tips

While building and running Remember, you might encounter some hiccups. Here are some troubleshooting ideas:

• If the app is not loading offline, ensure your service worker is correctly set up by consulting the MDN documentation.
• For issues regarding state management, revisit your Redux implementation to ensure every action and reducer is properly configured.
• If you face any performance issues, consider optimizing the components with React.memo to prevent unnecessary re-renders.
• Lastly, if errors still persist, don’t hesitate to consult your console logs for more descriptive error messages.
