Angular & NodeJS - The MEAN Stack Guide

Implement Angular event binding to capture input from a text area and trigger an onAddPost method on the Save Post button.

Explore getting user input in Angular with local references like postInput, read the value from input or textarea, and enable two-way binding using ngModel and FormsModule.

Learn to build a post-list component in Angular that outputs posts using Material expansion panels and an accordion, wiring it into the app module and styling 80% width.

Use structural directives like ngFor and ngIf to render a dynamic list of posts as expandable panels. Show a no-post placeholder and apply material typography for a clean, centered UI.

Create posts by adding a title and content, emit a postCreated event with EventEmitter, and bind the post to the parent using input and output to update the list.

Implement Angular forms with the forms module, ngModel, and template-driven approach to capture title and content, add HTML5 validations, and display dynamic error messages.

Learn to fetch and update posts in Angular using ngOnInit, a PostService, and RxJS subjects, subscribing to post updates and preventing memory leaks with ngOnDestroy.

Polish the Angular Material form by adding placeholders for labels, enable a floating label, reset the form with resetForm to reset values and validity, and prepare an edit/delete action bar.

Explore connecting a Node Express backend with an Angular app, using either a single server or separate static hosting, and implement RESTful APIs and routing.

Learn how to build a restful api with Node.js, defining stateless endpoints and json data exchanges using http verbs for a single-page Angular app and other clients.

Add express to a Node.js project, create an express app with middleware, establish routes, export and wire it to a server, and test with hello from express.

Improve the server.js by adding error handling and clearer output. Enable live reloading with nodemon and configure a valid port while adding a route to fetch initial posts.

Fetch posts from a node backend in an angular app by creating an express route /api/posts that returns a json object with a message and a posts array.

MongoDB is a NoSQL database that stores documents in collections, with documents like records and collections like tables, offering a flexible schema and easy Node/Express integration in the MEAN stack.

Compare NoSQL and SQL databases, focusing on schemas, documents, and relations, with MongoDB in the MEAN stack, and identify where each approach shines for logs, orders, and shopping carts.

Set up a MongoDB database using a cloud sandbox and connect it to your Angular Node Express app, configure users and IP whitelists for secure access.

Install mongoose, connect your node express app to MongoDB, and define schemas to store and fetch posts, enabling structured data in your MEAN stack project.

Connect our node express app to a MongoDB database using mongoose, import mongoose, and manage the connection with a promise to log success or handle errors.

Save a post with mongoose's save method to automatically insert a new document into the node angular database, creating the posts collection and object id.

Finish the edit feature by prepopulating the form with a post using template-driven ngModel, and implement a put update route with updateOne in MongoDB.

Update posts on the server and reflect changes locally by immutably replacing the post in the array, then fetch the post by id with a dedicated get-post route.

Organize the backend by moving post routes into a dedicated routes/posts.js file using express router, export the router, and mount it in app.js via app.use with the api posts path.

Validate image uploads by building a mime-type validator in Angular, reading the file as an array buffer, and exposing an async validator via RxJS observables.

Finish the image validator by reading file bytes with a Uint8Array to infer mime type, validate against PNG or JPEG, and wire an Angular async validator with form previews.

Implement server-side file upload with Multer in Express by configuring disk storage, destination and filename, validating mime types, and applying Multer as a post route middleware for a single image.

Add an image path to the post model and store the uploaded file's url on the server using Multer, then return posts with image paths to the client.

Bind the post image path in the post-list component to display images, then enable static access to backend images folder with express static and path.join, styling at 100% width.

Finalize the module by implementing file upload with a stylish picker, mime-type validation, and server handling, plus support for old paths or new file re-uploads to improve the app.

Implement an Angular Material paginator to control posts per page, bind total posts and page size, and handle page events to update the display.

Implement backend pagination for posts using query parameters page size and page. Use mongoose skip and limit to return the correct slice of posts.

Connect angular to the backend and fetch posts with a paginated get posts method using page size and page. Use template literals to build queries and initialize on page one.

Improve front-end pagination by showing a loading spinner during page changes, conditionally render the page-nator, and fetch posts with total count from the backend to emit posts with post count.

Finishing touches clean up post service logic, remove unnecessary subscriptions, re-fetch posts after delete, and implement pagination using a post data object with posts and post count.

Implement authentication to restrict post actions, letting readers view posts while only creators can create, edit, or delete, and add sign-up and login forms.

Handle user input using Angular's template-driven form by creating a login form with email and password fields, validators, and local references, then submit and log form values on login.

Learn to add a sign up screen by duplicating the login components in Angular, connect routes and header links, and prepare backend authentication and saving new users with Mongos.

Learn to create a user model and signup login routes in a node.js backend, using express, mongoose schemas, and the mongoose-unique-validator plugin to ensure unique emails.

Learn how the backend returns a token after successful authentication, send it to the frontend via a login service, store it, and use it for protected routes.

Transmit the expires in duration in seconds from the backend, parse it on login, and set a setTimeout timer to auto-logout when the token expires.

Decode the user id from the token in the check auth middleware, attach it to the request as user data, and store it as the post creator in mongoose schema.

implement robust error handling in an angular mean app by displaying helpful error messages for invalid email or password combinations and unauthorized actions, keeping the app stable and user-friendly.

Show error messages using an Angular Material dialog and a global error interceptor that catches HTTP errors with RxJS catchError and HttpErrorResponse; register the interceptor in app.module.

learn how to implement custom server error messages in a mean stack app, including signup, authentication, post creation, and fetching errors, plus front-end error handling and status codes.
