Full Stack With Flutter - Node - Express - MongoDB

Discover how mongoose acts as an ODM for MongoDB and Node.js, providing schemas, models, data validation, queries, and middleware to simplify deployment.

Connect to MongoDB by retrieving the connection string from the overview, replacing the password and user, installing mongoose, and wiring the connection in app.js with an env string.

Create a talks model using a mongoose schema with fields text (string, required, unique), day (date), and reminder (boolean, required), and enable timestamps to auto-manage created and updated dates.

Learn to create a new MongoDB document using a Mongoose model by taking the request body, calling model.create, and awaiting the result, while addressing timestamp schema issues.

Explore error handling in Node.js and Express.js, distinguishing programming errors from operational errors, with examples like missing properties and failed database connections, and build an error handling middleware.

Handle unhandled routes in express by adding a catch-all app.all middleware that returns a json 404 not found message, including original url, for all get, post, put, and delete requests.

Implement try-catch blocks in the tax controller to catch errors and return JSON responses with appropriate status codes for not found, bad request, and internal server errors in MongoDB operations.

Create a reusable custom error class in the util folder that extends Error, accepts a message and status code, and integrates with centralized error handling.

Implement a global error handler in Node.js Express to show stack traces in development and safe messages in production, using environment checks and operational vs programming errors.

Implement custom error messages for production server by refactoring the global error handler to generate user-friendly messages for cast errors, such as invalid path, and set appropriate status codes.

Learn how express middleware handles the request and response cycle, parses JSON bodies, and chains multiple middleware with next in a defined stack for security, logging, and authorization.

Configure a GitHub repository for the basic API. Initialize git, set gitignore for node_modules, .env, and .dvr, commit, set main, update readme, and push to remote origin.

Develop the get tax use case to fetch and map tax data from the repository, format dates with a date formatter, and provide the use case via riverpod provider.

Implement the get tax use case to fetch a single tax from the repository, map it to the tax model, and handle nulls and date formatting using a provider.

Create a map docs use case and map tax use case. Extract a tax item dto, apply a date formatter, and wire dependency injection via map docs use case provider.

Create a Flutter task UI with a form, text input, day and reminder fields, date and time pickers, and a save action that validates and submits via the view model.

update the task UI by cloning the create screen, fetch a single task by id from the api, update it, and show a toast before navigating back.
