In NodeJS, piping refers to the process of passing the output of one stream directly into another stream. It allows data to flow through multiple streams without needing to store it in memory or temporarily write it to disk. This is a common pattern used in file handling, HTTP requests, and other I/O operations in NodeJS.
Building REST APIs
- Start by working on small projects, such as a to-do list application or a weather app, and gradually move on to more complex projects.
- One of the key challenges that many businesses face is finding and hiring skilled software developers to meet their development needs.
- In Nest, we can test the correctness of any data getting in or out of the application by using pipes installing two dependencies – class-validator and class-transformer.
- ES6 introduced the let and const keywords, which are blocked scoped declarations that are not prone to the errors common to the var keyword.
- When it comes to building a successful software project, having the right team of developers is crucial.
- Use Targeted Resume to ensure your resume includes the right Node.js skills and keywords that match the job description.

Explain the tls module in NodeJS..
It uses decorators to define metadata for classes and methods, enabling expressive code. While Node.js is primarily a back-end technology, many Node.js developers also work with front-end technologies to build full-stack applications. If you have experience with front-end frameworks and libraries, such as React, Angular, or Vue.js, make sure to include them in your resume. Your resume skills section should showcase your proficiency with industry-specific softwares and programming languages.
They transform data to the desired format and evaluate data such that if the data is found valid, it passes unchanged, else, an exception is thrown. In order to use a pipe, you need to bind an instance of the particular pipe class to the appropriate context. Typically, a class should solely concentrate on fulfilling its functions rather than being used to create various objects that it might require or not. Nest supports dependency injection and you can use it in your Nest applications to enhance the modularity of your project.
- While the event loop in NodeJS runs on a single thread, it doesn’t block the execution of other tasks when waiting for I/O operations, such as file reads or database queries.
