How to hire Node.js developers
So how do you hire Node.js developers? What follows are some tips for finding top Node.js development consultants on Upwork.
How to shortlist Node.js development professionals
As you’re browsing available Node.js development consultants, it can be helpful to develop a shortlist of the professionals you may want to interview. You can screen profiles on criteria such as:
- Technology fit. You want a Node.js developer who understands the technologies you wish to use with Node.js to build the back end of your website.
- Project experience. Screen candidate profiles for specific skills and experience (e.g., combining a Node.js back end with a React front end).
- Feedback. Check reviews from past clients for glowing testimonials or red flags that can tell you what it’s like to work with a particular Node.js developer.
How to write an effective Node.js development job post
With a clear picture of your ideal Node.js developer in mind, it’s time to write that job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.
Job post title
2020欧洲杯体育投注平台Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample Node.js developer job post titles:
- Node.js developer needed for setting up the server side of a SPA
- Back-end developer with Node.js expertise
- Need help fixing Node.js security issues for an ecommerce site
Node.js project description
An effective Node.js developer job post should include:
- Scope of work: From back-end development to third-party integrations, list all the deliverables you’ll need.
- Project length: Your job post should indicate whether this is a smaller or larger project.
- Background: If you prefer experience with certain industries, software, or developer tools, mention this here.
- Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.
Node.js developer responsibilities
2020欧洲杯体育投注平台Here are some examples of Node.js developer job responsibilities:
- Implementing your preferred data storage solution (e.g., MySQL, MongoDB, PostgreSQL)
- Developing server-side logic for the user-facing front-end features of your website
- Building RESTful APIs and integrating your web app with third-party APIs
- Security, encryption, and data protection
- Writing unit tests
Node.js developer requirements and qualifications
2020欧洲杯体育投注平台Be sure to include any requirements and qualifications you’re looking for in a Node.js developer. Some examples:
- Node.js and supporting frameworks (e.g., Express, StrongLoop)
- Server-side templating engines (e.g., Jade, Vash, EJS)
- CSS preprocessors (e.g., Less, Stylus)
Node.js developers FAQ
What is Node.js?
How much does it cost to hire a Node.js developer?
2020欧洲杯体育投注平台The first step to determining the cost to hire a Node.js developer will be to define your needs. Rates can vary due to many factors, including expertise and experience, location, and market conditions.
Cost factor #1: project scope
The first variable to consider when determining scope is the nature of the work that needs to be completed. Not all Node.js development projects are created equal. Hooking up your application server to a well-known third-party API will typically take less time than building your entire Node.js-powered back end from scratch.
2020欧洲杯体育投注平台Tip: The more accurately your job description describes the scope of your project, the easier it will be for talent to give you accurate cost estimates and proposals.
Cost factor #2: Node.js development experience
Choosing the right level of expertise for the job is closely tied to how well you determined the scope of your project. You wouldn’t need an advanced Node.js developer to set up the back end for a simple business landing page. Hiring a less experienced Node.js developer who understands the basics of routing, templating, and setting up a database will be enough to get the job done at a lower price point.
2020欧洲杯体育投注平台Beyond experience level, you need to consider the specific skills and technologies a Node.js developer possesses. The following table breaks down the rates of the typical types of Node.js developers you can find on Upwork.
Rates charged by Node.js developers on Upwork
|Level of Experience||Description||Hourly Rate|
|Beginner||Can set up a web server with Node.js, hook up front-end features with back-end APIs.||$20-30+|
Cost factor #3: location
2020欧洲杯体育投注平台Location is another variable that can impact a Node.js developer’s rates. It’s no secret that you can leverage differences in purchasing power between countries to gain savings on talent. But it’s also important to factor in hidden costs such as language barriers, time zones, and the logistics of managing a remote team. The real advantage to sourcing talent remotely on Upwork is the ability to scan a global talent pool for the best possible person for the job. Location is no longer an obstacle.
Cost factor #4: independent contractor vs. agency
2020欧洲杯体育投注平台The final variable regarding talent cost is hiring an independent contractor vs. an agency. An agency is often a “one size fits all” model, so you’ll often have access to a designer, a project manager, an engineer, and more. When hiring individuals you have total autonomy regarding who is responsible for which part of the project, but you’ll need to source each of those skills separately.
The trade-off between hiring individuals vs. hiring an agency is the level of administrative overhead you incur personally in coordinating tasks among all members of the team. Project scope and personal preference will determine which style is a better fit for your needs.
Common Node.js developer mistakes
Accidentally blocking the event loop: Node.js runs on a single-threaded event loop to handle incoming and outgoing connections. The advantage of this nonblocking I/O architecture is that it achieves low latency and high throughput via concurrency. In other words, you don’t have to wait for an operation to complete before starting a new one.
2020欧洲杯体育投注平台But what happens if you unintentionally call a blocking I/O method with a nonblocking I/O architecture? Your entire event loop gets blocked until that piece of code gets executed, defeating the purpose of using a nonblocking I/O architecture. A large JSON payload or file can cause significant slowdowns to your application. That’s why you must make sure that if you are writing CPU-bound code, you have a good reason to do so and are sure it won’t impede general performance of your application.
Multiple execution of callbacks:2020欧洲杯体育投注平台 Node.js package APIs are often designed around asynchronous callbacks. The package function typically ends with a function as its last argument that gets called once the asynchronous task has been completed. If you forget to include a return statement after your first call, you risk executing it multiple times.
Not using supervisor programs: 2020欧洲杯体育投注平台Manually restarting your entire server every time you make a change or encounter an error can quickly get tedious. Supervisor programs monitor and orchestrate your development and production environments for errors or code changes. When an error occurs, your program crashes, or you make a change, the supervisor program will notice and automatically restart your application. This saves time and streamlines development.
Here are some examples of supervisor programs for Node.js:
2020欧洲杯体育投注平台Pick the supervisor program that best suits your needs.
Tips and best practices
2020欧洲杯体育投注平台One of the primary advantages of using Node.js over other server-side technologies is npm, short for Node Package Manager. It’s a massive library of code packages and the largest software registry in the world, so it’s worth searching for a solution before building one from scratch.
And while we’re on the subject of npm, get used to using npm scripts instead of bash scripts to help keep your Node projects organized and standardized for collaboration with other Node.js developers.
Practice test-driven development
Most developers test their code after they’ve written an implementation for a solution. Test-driven development (TDD) flips that concept on its head:
- Write failing tests
- Write the minimum code needed to pass your tests
- Refactor to best practices
Running unit tests as you code is the best way to ensure you’re consistently building safe, scalable applications. Of course if you’re going to be practicing TDD you’re going to need a tool to help you keep those tests organized, which brings us to our next tip…
Use a test suite
2020欧洲杯体育投注平台Pick the test suite that makes the most sense for your developer workflow.
