Build the register API for a MERN music player app by hashing passwords with bcrypt, checking for existing users, saving new users, and returning structured success or error messages.

Validate user credentials by querying the database for the provided email, compare the password with the stored hash, issue a JWT token for authentication, and store it in local storage.

Explore authorization in the authentication module by using a middleware to verify JWT from the authorization header and return protected user data for authenticated users.

Implement protected routes with a ProtectedRoute component that validates the user on each refresh and redirects unauthorized users to login, plus a public route to guide logged-in users to home.

Set up redux toolkit in the client, create alerts and user slices, implement loading indicators and toasts for API requests, and configure the store and provider.

Implement a loading overlay with a spinner in the MERN stack music player app, using a loader component, useSelector, and dispatch to manage API request states.

Design a minimal default layout for the MERN stack music player app, featuring a header with brand and logged-in user, a body with an all-songs list, and a bottom player.

Develop the song model on the back end and seed songs in MongoDB. Implement the get all songs API to power the front-end song UI, with search and playlist features.

Seed static songs into the MongoDB songs collection, format and import the json data, and implement the get all songs api with express and auth middleware.

Fetch all songs with axios post to the backend, secure with authorization header, then render them in the songs list on the home page and populate a playlist section.

Build a three-part music player component with image and song details, the audio element with controls, and volume controls, wired to Redux for the current song and next/previous.

Attach songs to the HTML audio element using React refs and build custom next, previous, and duration controls to play different tracks in the MERN stack music player.

Build a custom audio player for a MERN stack music app, replacing default controls with icons and using a stateful isPlaying flag and an audio element ref.

Implement next and previous controls by tracking the active song with a song index. Update the current song and pause, load, and play the new track on change.

Implement time and duration handling in the audio player with a timer slider showing current and total duration, updating on time changes, and enabling seeking via the range input.

Implement volume controls for the audio player in the Mern stack music app, including a range slider and mute functionality, and auto-select the first song when none is chosen.

Learn to build and manage playlists in the MERN stack music player app, creating a selected playlist from all songs, fetching user playlists from MongoDB, and preparing for playlist creation.

This lecture builds a create playlist screen in the MERN stack music player, featuring a playlist name input, song selection, and saving to update the user playlist.

Implement add and remove song logic for a playlist, toggle song selection with on click, update UI and save button state, validate and post playlist via Axios, then navigate home.

Develop back-end for create playlist in MERN Stack Music Player App 2022, attaching user id, adding name and songs to user playlist, and returning updated user data.

Update playlists in the MERN stack music player by using new: true in MongoDB, while redux selects a playlist for edit and only the songs are updated.

Learn to implement delete playlist in a MERN stack music player app by sending the playlist name to the backend, updating state with dispatch, and handling success and errors.

Perform a round of testing across login, registration, and playlist modules; fix validation, navigate to login on success, and address edge cases for next/previous, scrolling, and across the app playback.
