The speaker, Chelsea Andrade, presents her MIT Banking Application Capstone project. She discusses the front-end architecture, authentication process, and app diagram. The front-end is built with React.js and connects to a RESTful API. The project structure is divided into client and server folders for organized development. The navigation bar allows users to access account creation, login, deposits, withdrawals, and more. Authentication is securely handled, and data flows from the front-end to the back-end through API calls. MongoDB is used as the database, which integrates smoothly with Node.js. APIs are explained as intermediaries that facilitate software communication. The routes in the API handle GET requests to retrieve data from the database. The project is deployed on Amazon and uses GitHub for code transfers. New features are constantly added to improve the user experience. The presentation concludes with a live demonstration of the deployed application. Hello everyone, I'm Chelsea Andrade. Welcome to my MIT Banking Application Capstone presentation. Today I'm taking a deep dive into the intricate layers of my project, unveiling the front-end architecture, the authentication process, and dissecting my app diagram. Let's start with a quick snapshot. Our front-end powered by React.js forms a seamless connection with a robust RESTful API. Complementing this, the back-end utilizes React.js and a Node.js API, crafting a foundation for a dynamic and responsive user interface. Now let's delve into the pivotal components. Our project structure boasts a meticulous division into client and server folders. These house not only HTML and CSS, but also React.js components, back-end logic, and server-side components, providing a structured and organized architecture. At the forefront of user interaction lies the navigation bar. It acts as the gateway, granting users easy access to vital features like account creation, login, deposits, withdrawals, bounce, checks, and comprehensive data access. Authentication is a crucial aspect where the front-end transmits a complete account record to a server, securely stored in MongoDB. During login, the front-end meticulously verifies user credentials, email, and password through intricate back-end logic. Let's take a closer look now at how data flows through our application. Our data flow begins with user interactions on the front-end, whether it's a click on a button, a form submission, or any other action. These events trigger a series of actions within our application. When a user interacts with the front-end, let's say by making a bounce inquiry, the request is captured by the React.js components responsible for handling that particular feature. Once the React.js components have processed the user's action, the next step is to communicate with the back-end. This communication is facilitated through RESTful API calls. On the back-end, our Node.js API, equipped with the necessary logic, receives the request. In the case of a bounce inquiry, it might involve querying the MongoDB database to retrieve the user's account information. The retrieved data is then processed and made available through the context in React.js. Context acts as a bridge, allowing different parts of the application to access and share this information without the need for prop drilling. With the data now available in the context, our UI components are updated dynamically. This ensures that the user sees the most recent information without the need for a full-page reload. And there you have it, a simplified overview of how data flows through our application. The seamless process ensures a responsive and dynamic user experience. In our main presentation, we'll continue unraveling the layers of our project, exploring authentication and other crucial aspects. To hold our app diagram, a visual roadmap, and illustrating the harmonious interplay of components. This includes the navbar, routes, and various UI components, fostering seamless data exchange facilitated by React's context. Let's visualize our app diagram. Key components include the navbar for easy navigation, routes defining different paths, component size building blocks, and context for data sharing across components. To sum up, our front-end architecture is built on React.js, integrated seamlessly with the RESTful API, and communicates with the DAO. Stay tuned for video 2, where we'll explore databases and APIs in depth. Welcome back. Let's now delve into our database and API choices. MongoDB database supports indexing, which enhances the speed of query execution. By creating indexes on specific fields, we can quickly locate and retrieve data, optimizing the overall performance of our application. MongoDB seamlessly integrates with Node.js, our chosen back-end technology. This integration allows for smooth communication between our server-side logic implemented in Node.js and the MongoDB database, ensuring efficient data retrieval and manipulation. That concludes our overview of MongoDB's features and its integration within our application in the main presentation. We'll continue exploring our API, including its routes, interactions with MongoDB, and how it facilitates communication between the front-end and the database. API as a super helpful tool that allows different pieces of software to talk to each other. In coding, it's like the magic wand that makes things work smoothly. APIs act as intermediaries, facilitating smooth connection between various software elements. This not only enhances the app's performance, but also streamlines updates and compliance with regulations. In essence, APIs are the architects of seamless and efficient software communication, playing a critical role in the technical backbone of this banking application. API in simple terms. A person walks into a restaurant, sits at a table. So, do you ever wonder what APIs are and how they work? Let's break it down with a simple restaurant analogy. Think of an API like a restaurant menu. It's a set of options and just like you choose dishes from a menu, an API lets you select specific operations or information from a software system. Now, an API acts like a waiter, shuttling between the dining area and the kitchen. It's the bridge that facilitates smooth communication between different parts of the system. APIs often follow a RESTful style, a standardized way of presenting options, just like a restaurant menu. This makes communication between systems efficient and clear. In the tech world, the kitchen is like a database with various data and the API provides specific endpoints for interaction, similar to choosing categories from a menu. So, API simplify communication, much like a menu, streamlines your interaction with a restaurant kitchen. They're a predefined set of options, a bridge between components, and they follow a standardized style for efficient data exchange. Now, let's explore the specific routes in our API. The first route handles GET requests to the root URL it interacts with. The accounts collection in the database, retrieving data using the FIND method. The data is then converted to an array and sent as a response with a status code of 200. The second route handles GET requests with a specific ID parameter. It constructs a query using rec.perms.id, uses FIND1 to find a single document, and sends a document as a response with a status code of 200. If no match is found, it responds with a not found message and a status code of 404. To wrap up video 2, we've explored MongoDB as our database, discussed the benefits of our API, and built into the routes. In video 3, we'll cover deployment, additional features, accurate demonstration, and reflect on our journey. Stay tuned. In video 4, we'll cover deployment, new features, app demonstration, and reflect on our journey. Our app is deployed on Amazon. To wrap up video 2, we've explored MongoDB as our database, discussed the benefits of our API, and built into its route.
