1. Join communities and ask questions 🌐
While online developer communities may sometimes exhibit toxic behavior, great people who are willing to help still exist. Learning by discussing with others is a great way to stay updated.
Hints:
- 🎮 Discord communities
- 🤝 meetups and conferences
- 📱 social networks
2. Practice your algorithms 🧠
Regularly practicing algorithms is essential for improving your problem-solving abilities. Engage in algorithmic challenges on platforms like LeetCode, HackerRank, or CodeSignal to enhance your skills and become more comfortable tackling complex problems.
3. Securize your backend 🔒
I recently heard a lot of "My discord API has been token grabbed". Those sort of stuffs are due to guys that do not spend time to put in place the basic security measures.
Some tips:
- 💼 use environment variables instead of committing your TOKEN into Git platforms (pleaseeeee )
- ⏳ add rate limits to the API
- 🛡️ prevent SQL Injection
- 🔐 protect your API routes
4. Test your codes 🛠️
Testing is crucial for ensuring the reliability and correctness of your backend code. Learn about different types of testing such as unit testing, integration testing, and end-to-end testing. Use testing frameworks like Mocha, Chai, or Jest to write and automate tests for your Node.js applications. By writing tests, you can catch bugs early, improve code quality, and build confidence in your codebase.
Below is an example of a test using Jest:
it('should return true for valid email addresses', () => {
const validEmails = [
'test@example.com',
'user123@gmail.com',
'john.doe@company.co'
];
validEmails.forEach(email => {
expect(isValidEmail(email)).to.be.true;
});
});
5. Learn debugging techniques 🐞
A lot of bugs when we are starting a programming project may be quickly solved just by having a basic debugging techniques.
Familiarize yourself with debugging techniques specific to Node.js, such as using the built-in debugger, console.log statements, and logging libraries like Winston ( https://github.com/winstonjs/winston ) or Bunyan. Understanding how to set breakpoints, inspect variables, and trace the flow of execution will help you diagnose and resolve issues more efficiently.
Conclusion
The list above is of course far from being exhaustive.
