Overview
The Vitality Visit clinic wanted to create a mobile app that allowed patients to communicate with their doctors, schedule appointments, and view their medical records. They decided to use ReactJS for the frontend of the app and NodeJS for the backend
Requirements
Our client wanted following features in the app:
- Patients should be able to communicate with their doctors
through secure messaging. - Patients should be able to schedule appointments with their
doctors. - Patients should be able to view their medical records, including
test results and prescription history. - The app should have secure authentication and authorization
features.
Solution
The development team decided to use ReactJS for the frontend of the app because of its ability to efficiently render components and handle user interactions. They also decided to use NodeJS for the backend because of its ability to handle high volumes of requests and its support for JSON Web Tokens (JWTs) for authentication and authorization.
For the messaging feature, the team implemented a ReactJS component that displayed a list of conversations with the patient's doctors. The component included a form for sending messages and displayed new messages in real-time using websockets. The component was connected to the backend using an API that stored the messages in a database.
The appointment scheduling feature was implemented using a similar approach, with a ReactJS component that displayed a calendar of the patient's appointments and allowed them to schedule new appointments. The component was connected to the backend using an API that stored the appointment data in the database.
The medical records feature was implemented using a ReactJS component that displayed the patient's test results and prescription history. The component was connected to the backend using an API that retrieved the data from the database.
For secure authentication and authorization, the team implemented JWTs on the backend. When a user logs in, the backend generates a JWT and sends it to the frontend, which stores it and includes it in the header of subsequent requests to the backend. The backend verifies the JWT before processing the request.
Results
The doctor-patient mobile app was successfully launched and received positive feedback from patients. They appreciated being able to communicate with their doctors and view their medical records using the app. The appointment scheduling feature was also well-received and made it easier for patients to schedule appointments with their doctors. The use of JWTs for secure authentication and authorization helped to give patients confidence in the app's security.
This route uses the verifyToken middleware function to verify the JWT in the request header before allowing the request to proceed. If the JWT is not present or is invalid, the middleware function returns a 401 Unauthorized status. If the JWT is valid, the userId field is extracted from the JWT and added to the request object. The route then uses the userId to find the user's medical records in the database and returns them in the response.
This component uses the socketIOClient library to connect to the server using websockets. It subscribes to the message event to receive new messages and updates the messages state variable with the new message. It also includes a form for sending new messages and emits a message event to the server with the new message when the form is submitted. This allows for real-time communication between the client and the server.
Here are some technical details of the doctor-patient mobile app:
On the frontend, the development team implemented a messaging component using ReactJS that displayed a list of conversations with the patient's doctors. The component included a form for sending messages and displayed new messages in real-time using websockets. They also implemented an appointment scheduling component that displayed a calendar of the patient's appointments and allowed them to schedule new appointments. The medical records feature was implemented using a component that displayed the patient's test results and prescription history.
On the backend, the development team implemented APIs using NodeJS that handled the messaging, appointment scheduling, and medical records features. They stored the data in a secure database and implemented JWTs for secure authentication and authorization. When a user logs in, the backend generates a JWT and sends it to the frontend, which stores it and includes it in the header of subsequent requests to the backend. The backend verifies the JWT before processing the request.
The development team chose to use MongoDB as the database for the platform. They stored the messaging, appointment, and medical record data in collections in the database and implemented appropriate indexing to allow for fast querying of the data. They also implemented security measures to protect the privacy of user data.
The development team implemented JWTs for secure authentication and authorization. When a user logs in, the backend generates a JWT and sends it to the frontend, which stores it and includes it in the header of subsequent requests to the backend. The backend verifies the JWT before processing the request. This ensures that only authenticated and authorized users have access to the data.
The development team used websockets to enable real-time communication between the client and the server for the messaging feature. They used the socket.io library on the backend to handle the websocket connections and the socketIOClient library on the frontend to connect to the websocket server. They implemented event-based communication, with the client emitting events to the server and the server emitting events to the client. This allowed the messaging component to display new messages in real-time as they were received.
