This project is a test assignment designed to simulate real-world development scenarios and assess my skills. It involves fixing a verification issue on the registration and login processes, integrating a wallet connection feature on the profile page using Web3, and displaying the current Ethereum price on the user profile page. The project is built using Node.js version 16, and you'll need to work with potentially deprecated packages due to this version requirement.
Before starting, ensure you have Node Version Manager (NVM) installed on your system. NVM allows you to easily switch between different versions of Node.js. To install NVM, follow the instructions on the official NVM GitHub repository. Once NVM is installed, you can set up the project environment by running the following commands:
nvm install 16.5.0
nvm use 16.5.0Ensure you are using the correct node version by running
node -vFrom the root directory, run the following command to install client/frontend dependencies
npm installNavigate to the backend directory and install dependencies by running
cd backend
npm installTo start the project, you'll need to have MySQL and Apache running on XAMPP or any other mysql client eg mysql workbench.
From the root directory of the project, execute the following command:
npm run devThis command starts both the client and server concurrently.
Ensure your database and Gmail credentials are correctly configured in the backend/.env file.
I addressed the verification issue by commenting out the API server and replacing it with my localhost server. This change allowed me to bypass the original server's limitations. Additionally, I edited the SQL migration to create a users table, including the get_bnb column. For the email verification issue, I updated the environment variables to use Gmail's SMTP service, configured the host port to 465, and added my own credentials. This setup resolved the email verification problem, and everything worked as expected.
The second task was dependent on user authorization errors. After successful registration, the create wallet function and add eexisting wallet based on key phrase was working as expected. On the profile page, the wallet is alredy connected
For the third task, I utilized the existing implementation of market prices and rendered only the price for Ethereum on the user profile page. By leveraging the existing implementation of market prices, I rendered only the Ethereum price on the user profile page. This approach simplified the task by avoiding unnecessary complexity and focusing on the core functionality.
One area for improvement is the error messages for form submissions, such as when an "email is inavalid" in the email_verify upon requesting a code. These messages should be more informative to the user. For instance, instead of a generic "Email is invalid", a message like "The email address you entered is already registered. Please use a different email address." would be more helpful. This approach aligns with best practices for error messaging, making it easier for users to understand and correct their mistakes.
The user interface is intuitive overall, but there's room for improvement in terms of content alignment. Specifically, the centering of content in the "Access Wallet" and "Create Wallet" cards could be adjusted for better visual appeal and consistency with the rest of the design.
Completing this project has been a rewarding experience, especially overcoming the challenges posed by working with deprecated packages. It has honed my problem-solving skills and deepened my understanding of Node.js development practices. I'm excited about the opportunity to contribute to your team and look forward to discussing my solutions further.
