Hi all! We are finishing our series of articles on the best open source projects for web development. If you haven’t seen our past articles about Vue, React, Angular, Node.js – they’re strongly recommended.
Here’s what this last one is about: projects we included in our collection, criteria we grouped them by, and how to choose an open source project in order to make a contribution to it.
Note that under open source projects we assume the following:
- Node.js frameworks
- Tools which can be used in Node.js
- Node.js server applications
- Fullstack applications (Vue, React, Angular etc. on the front-end and Node.js on backend) which use Node.js on the server side ##What is Node js? Node js is a cross-platform, open source runtime environment for executing JavaScript code outside of the browser. It is event-driven and works on a non-blocking I/O model, making it lightweight and efficient for building web applications. Node js is just another way to run code on your computer, being just the environment for running JavaScript.
With Node.js, you can run your code simultaneously on both the client and the server side, speeding up the whole process of development. Node js’ rising popularity has also produced a wave of open source projects and tools to help developers work with the environment. A part of our admin templates has an integrated Node.js backend (you can start getting to know our products with an angular dashboard).
Pros and Cons of Node js
Pros
- Uses JavaScript, which is easy to learn
- Shares the same codebase with both server and client side
- It has seamless JSON support
- Node.js has active community, with lots of code examples ###Cons
- It is very to hard to deal with relational databases when you use Node.js
- Callback hell
- Performance bottlenecks with heavy computation tasks ##Reasons to use Node js in projects
- You can build very fast useful tools like chats, fileuploads etc
- Non-blocking code. This approach helps the application not to pause or sleep, but to become available for other requests
- Fast processing. Node uses V8 JavaScript Runtime engine, the one which Google Chrome uses, and – believe us – it is very fast
- One environment
- A great number of tools that can help in everyday development – CMS, chats, spreadsheets, form validation and other libraries
- Larger community that can provide support for free or on a commercial basis ##Criteria of choosing a node js open-source project to contribute to ###Number of Github stars and npm downloads This is the most valuable criteria (joking!). Obviously, just because the repo is popular/widely used, it doesn’t necessarily mean it will be useful to contribute. Still a good sign, though.
Documentation
Documentation is probably one of the most important things to look for when you’re assessing a project. Docs are like entry points to the project.
Good documentation will usually include:
- A README.md file in the root of the project. This should have the public API/functions listed, as well as what they do and how to use
- Examples in the documentation or a separate folder containing multiple examples
- Contribution guide
- FAQ ###Recent development and open issues You should look at the recent issues and bugs, how they’re organized. By checking these items you can know if the project is still maintained. If it’s not, you may run into the issue of some things not working that may affect your understanding of how the project works.
On the other side, if a project has a lot of open issues, don’t disqualify it: these might be questions from users, ideas or non-critical bugs.
Tests
Having a test would be a great addition to good docs and good code structure.
Structure/Code organization
How well the code is organized shows the quality of the project. See the name of the folders, comments and index.js file.
Other criteria
- Project size;
- The project needs to be something you use
- Something you’re interested in learning
- Something that your team does use ##Best node js open source projects We tried to select the projects along several lines:
- more than 5,000 github stars
- solving one specific problem very well
- being super useful in developing web and mobile applications

Cube.js is an open-source modular framework to build analytical web applications. It is primarily used to build internal business intelligence tools or to add customer-facing analytics to an existing application. Cube.js was designed to work with Serverless Query Engines like AWS Athena and Google BigQuery. Multi-stage querying approach makes it suitable for handling trillions of data points. Most modern RDBMS work with Cube.js as well and can be tuned for adequate performance.
It is essentially not a monolith application, but a set of modules, each doing one thing really well. Cube.js provides modules to run transformations and modeling in data warehouse, querying and caching, managing API gateway and building UI on top of that.
We at Flatlogic even built a demo and wrote an article on how to build an application using Cube.js: you can check it out.

Conclusion
We’ve mentioned some of the most popular and useful Node js open source projects. We tried also to be helpful with choosing open source projects for contribution. Btw, you can also find some useful stream analytics software here.
We hope you’ve found some interesting Node js open source projects to try, or actively contribute to. If you found this article interesting, please share it on socials!
Bonus: Creating an App of your own with Flatlogic
We’ve listed some of the best open source projects to help you in your web development aspirations. Now let’s take a look at another approach to web development. At Flatlogic, we have created a platform that strips web development down to a few choices. Keep reading to know what they are!
1: Name your Project
This step is straightforward enough. Any name consisting of symbols the Platform recognizes (it’ll tell you if it doesn’t) that is easy for you to associate with the project will do.
2: Define Tech Stack
Flatlogic Platform: Choose Tech Stack
An application’s stack is the combination of technologies it uses. We need to choose underlying technologies for the front-end, the backend, and the database. In the example above we’ve chosen React for the front-end, Node.js for the backend, and PostgreSQL for the database.
3: Choose the Design
Next up, let’s choose the design. This part is mostly aesthetical and a matter of taste. However, you might spend a lot of time using the interface, so choose wisely.
4: Define the Database Schema
The Schema is the combination of parameters that form the database’s structure. Fields, columns, data types, and relationships between those. This may seem difficult at first but recalling what information you plan to deal with and how you want it processed usually helps. If it’s still challenging or if you’re short on time, pick one of the ready schemas the Platform offers. We’ve crafted them to cover the most popular demands, and at least one of them will likely fit your needs.
5: Finishing Touches
We’ve made all the main choices. Now it’s time to review them and hit “Finish” if everything’s fine. You can select the “Connect GIT Repository” checkbox if you want to. Or you could host your App locally in one click. Once you hit “Finish”, the Platform will take a couple minutes to compile, and offer you your very own web application. Hit “Deploy” and start using it.
Thanks for reading and, as always, your feedback is welcome!
