An introduction to NodeJS and Express
Middleware is like a bridge that helps different parts of a software application talk to each other smoothly.
Express is the most popular web framework for Node.js.
Express being “unopinionated” means it doesn’t force you to use specific tools or patterns, giving you flexibility in how you build web applications.
A module is like a toolbox that contains pre-made bits of code, and modularity is useful because it helps developers organize and reuse code, making projects easier to manage and collaborate on.
You can check the npm version by running
npm -vin your terminal.
To install the ‘jshint’ library/package in your Node project, you can use the command
npm install jshint.
Tests are crucial because they act like safety nets for software. Just like how seatbelts keep us safe in cars, tests ensure that our computer programs work as expected, reducing the chances of errors and making technology easier and more reliable to use.
Testing helps catch bugs early, improves code quality, and provides documentation for how the software should work, making it easier for developers to collaborate and maintain projects over time.
Individual pitfalls include writing tests that are too complex or not covering enough scenarios. Team pitfalls often involve inconsistent testing practices among team members and insufficient communication about testing goals and strategies.
Continuous Integration (CI) helps catch and fix bugs early in the development process, ensures that code changes don’t break existing functionality, and promotes collaboration among team members by providing a centralized and automated testing and deployment process.
Continuous Delivery (CD) is a practice where code changes are automatically built, tested, and prepared for release, but the actual deployment to production is a manual decision. In contrast, Continuous Deployment (CD) takes automation a step further by automatically deploying code changes to production as soon as they pass all tests, without manual intervention.
Think of GitHub as a digital platform that acts like a collaborative workspace for software development. It’s like a place where multiple people can work on a document at the same time, but instead of a document, it’s a piece of software. GitHub helps developers store and manage code, track changes, collaborate with others, and ensure that new code updates are thoroughly tested before being used by real users.
