Rate Limiting an Organization's HTTP Requests
In this lesson, we'll cover how to throttle how often an organization can hit our API using HTTP Rate Limits, which is crucial for preventing spam, limiting content access, and managing server load.



User-Defined Relationship Loading
In this lesson, we'll let our users tell us which relationships they'd like to get back in our lesson search. We'll also discuss how to handle nested relationships and what to watch out for.



Filtering Lessons by Publication Date
In this lesson, we'll add the ability to search lessons by their publish date and time. We'll utilize before and after properties to allow for filtering that can look forward, backward, or within a specific date range on our lesson's publish at column.



Searching and Filtering Lessons
In this lesson, we'll take the filters we've created thus far and apply them to a new lessons search endpoint. We'll be able to search our lessons by name, status, access level, and module.



Making our Search Course Action Easily Reusable
In this lesson, we'll make our search course filters optional to increase the reusability of our action. We'll then switch our courses index route handler to use this action.



Filtering by a Number or Array of Numbers
In this lesson, we'll implement our number filtering system in which we'll allow our search APIs to accept a single number or an array of numbers to filter the data by. To validate this, we'll use the union rule from VineJS.



Advanced String Filtering
In this lesson, we upgrade our course name filter to support both simple strings and advanced object-based queries using VineJS’ union rule. This allows users to specify not just what to search for, but how to search for it.



Basic Course Search & Filter
In this lesson, we'll add a new search endpoint for our courses and enable some basic filter functionality along with it. We'll be able to search by course name likeness, status, difficulty, and/or access level.



Getting A Module's Lessons
In this lesson, we'll remove our lesson's index method in favor of a module method whose purpose will be to fetch a module's specific lessons in their stored order.

The Flow of Middleware
In this lesson, we'll learn about the middleware that comes preinstalled within AdonisJS and the flow of this middleware during an HTTP Request at both a global and route-specific scale.


Checking For and Populating an Authenticated User
In this lesson, we'll create a silent auth middleware that will automatically check whether a request has an authenticated user attached to it, and populate that user's details if one is found.


Authenticating A Newly Registered User
In this lesson, we'll learn how we can authenticate, or login, a new user who just registered with our application. We'll then see how we can populate the authenticated user's details on subsequent requests.


AdonisJS 6 Session Authentication in 15 Minutes
In this lesson, we'll learn how to add authentication to a new AdonisJS 6 application using the session guard. In these 15 minutes, you'll learn how to register a user, logout a user, verify a user's credentials and log them in, and more.


Creating A Login Form and Validator
In this lesson, we'll apply what we've learned to create a login page as well as a validator for our login form.


Creating An EdgeJS Form Input Component
In this lesson, we'll create a form input component with EdgeJS to simplify adding inputs throughout our application and to extract away old value and validation error logic.


How To Create A Custom VineJS Validation Rule
In this lesson, we'll learn how to make a custom validation rule with VineJS that requires a value to be unique for the provided table and column. We'll learn how we can register this rule for both strings and number types.


Validating Form Data with VineJS
In this lesson, we'll learn how to validate form data using AdonisJS homegrown validation library, VineJS. With VineJS we can easily ensure our request body consists of properties we need, in the types we need them, with valid values.


Reusing Old Form Values After A Validation Error
In this lesson, we'll learn how we can easily repopulate our form input values with their previously submitted values when our VineJS validator finds and sends back an error.


Displaying Validation Errors and Validating from our Request
In this lesson, we'll learn how we can display feedback for invalid fields noted by errors from our VineJS validators. We'll also see how we can validate directly from our request using request data.


Accepting Form Data
In this lesson, we'll take a look at how we can create a register form and accept data from that form within our route handler.


How To Query, Sort, and Filter by Pivot Table Data
In this lesson, we'll learn how we can query pivot table data. We'll then learn how we can also sort and filter our results by those pivot table columns as well.


How To Create Factory Relationships from a Pool of Data
In this lesson, we'll learn how we can refactor our fake data seeder to allow us to assign cast members and crew members to our movies via our many-to-many relationships from a single pool of cineast records.


Many-To-Many Model Factory Relationships
In this lesson, we'll learn how we can define and use many-to-many relationships with Model Factories, including how we can define pivot table data when creating our fake records.


A Deep Dive Into Relationship CRUD with Models
In this lesson, we'll take a deep look at how we can perform CRUD operations with one-to-one, one-to-many, many-to-one, and many-to-many relationships using our Lucid Models.


Defining Many-To-Many Relationships and Pivot Columns
In this lesson, we'll learn how you can define many-to-many relationships within your Lucid ORM Models. We'll also discuss the relationship options, and how you can automatically include pivot table data with all queries.


Listing A Director's Movies with Relationship Existence Queries
In this lesson, we'll learn how we can perform a relationship existence check to grab a list of our cineasts who have directed one or more movies. We'll then create a show page for that director, listing the movies that they directed.


Using Eager and Lazy Loading to Load A Movie's Writer and Director
In this lesson, we'll learn how we can use eager loading to preload our writer and director onto our movie's details. We'll then, learn how we can load our writer and director onto our movie's details using lazy loading.


Listing and Counting a Writer's Movies
In this lesson, we'll learn how we can perform multiple different relationship counts with the same relationship using the Model Query Builder. We'll count our writer's total number of released and not-released movies.


Cascading and Deleting Model Relationships
In this lesson, we'll learn how to account for foreign key constraints when deleting relationships using our Lucid Models. We'll then learn how we can automatically cascade deletions through to relationships.
