Deciding on a Tech Stack for a Node.js Developer
When hiring a Node.js Developer, it's essential to decide on a tech stack that complements Node.js's capabilities. Consider whether your project requires a MEAN (MongoDB, Express.js, AngularJS, Node.js) or MERN (MongoDB, Express.js, React, Node.js) stack for full-stack development. For backend-focused roles, assess how Node.js integrates with your database choices, like MySQL or PostgreSQL, and whether you'll utilize frameworks like Express.js or Koa.
Assessing skills of a Node.js Developer
Assessing a Node.js Developer's skills involves evaluating their proficiency in JavaScript and understanding of Node.js-specific concepts like asynchronous programming, event-driven architecture, and working with Node.js modules. Additionally, gauge their experience with RESTful API development, error handling, and security best practices in Node.js applications.
