How much does it cost to hire an offshore ExpressJS developer?

ExpressJS is a bare-bones NodeJS framework used for web application development. With ExpressJS, you may not repeat the code as it already has what you need for the base development of RESTful APIs web applications. This framework helps organize web apps into MVC architecture and manage such processes as routes and even users’ input.

ExpressJS also has some features that distinguish it from other frameworks.

• Middleware. It has access to the database and clients’ requests. The main function of it is the organization of functions of ExpressJS.
• Fast server-side development. As ExpressJS allows users to use many features of NodeJS as templates of functions, it shortens development time as you can use them anywhere in the code.
• Debugging. ExpressJS provides users with an easy debugging process to determine which exact part of the code has bugs.

ExpressJS is a JavaScript back-end framework widely used by back-end developers. You can build and design different kinds of web applications easily and quickly. It also provides developers with simple routing for clients’ requests. Moreover, EspressJS provides the middleware that helps to make the right decisions about what response to give for clients’ requests.

Here’s the list of the most important stack that is used with ExpressJS:

• Git. It is the most common version control system that will help keep the application working without worrying that something may be corrupted.
• Environment-to-go. It is better to have a stack as close to your project as possible with a decreased amount of errors by using different versions, with cloud integration (AWS, Google Cloud Platform, IBM, etc.) and all the necessary libraries (SQL, MySQL, etc.).
• Package Manager. If talking about the JavaScript package manager, there are two the most common: Yarn and NPM. It is better to use NP as it comes with every NodeJS installation and switches to Yarn only if there is a real need.

ExpressJS developers use the ExpressJS framework for developing and maintaining web applications. There are also some of the main things they do: design, developt, debug, and maintenance of web applications and back-end components; manage data exchange between users and servers; connect web applications with servers.

If talking about the experience levels of developers, there are three common levels:

• Junior ExpressJS Developer
  Junior ExpresJS developers usually have from 0 to 2 years of experience with ExpressJS. They have basic knowledge of such web development elements as CSS, JavaScript, HTML the development process using the ExpressJS framework and NodeJS. Junior ExpressJS developers also have basic knowledge of core aspects acquired during their work path. The senior software engineers usually mentor junior developers and assign them to simple tasks. Such developers also work mostly in teams to learn new technologies from their more experienced teammates.
• Middle ExpressJS Developer
  Being a middle ExpressJS developer requires from 3 to 5 years of experience. During this time, the developer must know a lot more than a junior developer and also be able to create their applications. Middle ExpressJS developers are also required to participate in problem-solving, generating ideas, and implementing them.
• Senior ExpressJS Developer
  Senior ExpressJS developer should have a high experience level (at least five years) and have advanced knowledge of some programming languages, NodeJS, ExpressJS framework, and other frameworks needed to create web applications. Science ExpressJS is a framework of NodeJS; you can hire senior NodeJS developers as they will know this framework for sure. Also, they should have advanced soft skills and tech skills that help them in managing the project and the team. They also often combine their work with job titles like a team lead or a project manager.

ExpressJS developers usually have the following set of tasks and responsibilities:

• Design, develop, debug, and maintain web applications and back-end components.
• Management of data exchange between users and servers.
• Connection web applications with servers.
• Take part and contribute to the development process as a team member.

Some skills are essential to have if you are an ExpressJS developer. Among them are the following:

• The knowledge of HTML, CSS, Java, Python, PHP, and JavaScript. If the developer is skilled in ExpressJS, they also are highly skilled in JavaScript. Being a full-stack developer or a front-end developer, they also should know such essential elements of web development as JavaScript, HTML, and CSS.
• NodeJS. Knowing the base language will help use all the advantages of the ExpressJS while developing the application. So, if you need a web developer who knows ExpressJS, you can hire NodeJS developers or even JavaScript developers, as in most cases, they know it.
• The advanced skill of asynchronous programming. This skill will be highly useful as NodeJS allows the development of several parts of the project simultaneously.

If you want to hire ExpressJS developers, you often have three options: freelancers, in-house engineers, and outsourced programmers.

• Freelance ExpressJS developer
  You can find and hire freelance ExpressJS developers on different freelancers platforms. As soon as they don’t belong to any company, their work will be finished as long as the project ends. A freelancer is a good option for companies with a small budget or short-term projects as such projects don’t require advanced skills or long-term relationships between the company and the developer. Although, there is a bad side: it is quite hard to find a freelance ExpressJS developer who will fit all your job requirements, and mostly they are not skilled and experienced enough. Often, it is hard to find skilled developers among freelancers as they usually work on interesting projects in reputable companies.
• In-house ExpressJS engineers
  In-house engineers are a good option if there is a need to develop the software’s core. They are also very dedicated and more interested in providing high-quality end products than freelancers. In-house developers also can generate great ideas on how to create the best product and meet all the requirements. If you want a team that will be dedicated and highly skilled, then in-house engineers are what you need. Although it is a good option, it is still quite expensive as you will have to provide the in-house developers with appropriate technologies and tools, pay bonuses, and this model always requires extra spending.
• Outsourced ExpressJS developers
  You can hire outsourced developers through the development agencies or with YouTeam outstaffing model. These developers can be a helping part of your in-house developers or as an independent development team. It is also a good option if you need to hire developers in a short time. With YouTeam, you can find the best candidates in less than two days. If you need developers who have the same level of skills and experience as your in-house team, try outsourcing or outstaffing model.

Before hiring an ExpressJS developer, you need to point out which requirements and skills you want the developer to have and what result you expect them to do. Below we will describe what exactly you need to write in your ExpressJS project description.

• Describe expectations of the project;
• Write some words about your company and the field you work in (it will help the developer to come up with some good solutions for you);
• Point out the development stage (it helps developers to know what are their responsibilities: development from scratch or only maintenance and updating);
• List tech and soft skills you need the developer to have;
• Point out the responsibilities the developer will have.

Before hiring, it is also required to check the expertise of the developer. You can ask them to take an online test and ask them questions connected to their field of expertise. Here are some of the questions you can ask the developer on the online interview:

• What is the difference between ExpressJS and NodeJS?
• What does an ExpressJS code look like?
• What do you understand by Scaffolding is ExpressJS?
• Which are the arguments available to an ExpressJS route handler function?
• How can you deal with error handling in ExpressJS? Explain with an example.
• What is MongoDB? What are the different types of middleware?
