Web Development with Julia

The web is a mind-blowing place that has evolved over the years with various tech innovations, which have brought about great improvements.

Also, diverse programming languages have contributed to this progress and building on the web. For example, popular languages like PHP and JavaScript rule the web.

Aside from these popular languages, other languages support building on the web, like Python (with PyScript) and Julia. In this article, we will be looking at how web development is possible with Julia and packages that can be used for web development.

What is Julia?

Julia is an open-source, high-level, and dynamic language that combines ease of use and speed. It is a general-purpose language that has many applications.

Julia is known for its speed and efficiency, as it compiles code just-in-time (JIT) to machine code, allowing it to perform at speeds comparable to that of low-level languages such as C and FORTRAN.

Amid the applications, web development is also part of. Julia supports web development and API creation. Before listing what packages support web development in Julia, what exactly is web development?

What is Web Development?

Web development is the process of building websites or web applications that can be accessed over the Internet. Web developers use programming languages, tools, and technologies to design, build, and maintain websites.

Web developers aim to produce websites that are aesthetically pleasing, interactive, and user-friendly while also ensuring that they work effectively on various devices and web browsers.

Julia and Web Development

There are various packages in the Julia Language ecosystem that support web development. In this section, we will be looking at some of these packages and how to put them to use:

The Genie Framework

The Genie framework is an open-source web application framework developed to simplify web development in Julia and to provide a fast and efficient platform for building web applications.

The Genie framework provides a full-stack web development framework that includes tools and features for front-end and back-end development. It also offers three packages: Genie, Stipple, and Searchlight.

Genie can be described as the backbone of the Genie framework and uses the MVC architecture. It is used to build full-stack applications and supports HTML, Markdown, and JSON. It is very powerful as it comes with many benefits, code generators to get started with, and it is extended to provide features via plugins.

Stipple, on the other hand, is a UI library for building interactive data applications. It offers a lot of UI elements like buttons, sliders, inputs, and many more for users to generate interactive dashboards quickly. It can also be extended to incorporate custom UI features.

Lastly, there’s SearchLight. SearchLight can be described as the complete Object Relational Mapping (ORM) for Julia. It supports databases such as MySQL, Postgres, and SQLite. It provides many features, such as database schema versioning through migrations, transaction support, and much more.

To get started with the Genie Framework, kindly visit the official documentation website, navigate to the package of choice, and read the documentation.


Franklin is a Julia package that is used for building simple lightweight static websites. A static website consists of HTML, CSS, JavaScript, and other client-side files stored on a server and sent to the user's web browser as-is. The content of a static website remains the same for all visitors, regardless of their location or previous interactions with the site.


HTTP.jl is a package for Julia that provides a simple and lightweight HTTP client and server implementation. HTTP stands for Hypertext Transfer Protocol. It is a standard application-level protocol used for exchanging files on the web.

HTTP.jl provides both client and server functionality for the HTTP and WebSocket protocols. On the client side, HTTP.jl provides a simple and intuitive API for making HTTP requests to remote servers. It supports various HTTP methods such as GET, POST, PUT, DELETE, etc., and can handle various data formats such as JSON, HTML, and XML.

On the server side, HTTP.jl provides a lightweight HTTP server implementation that can be used to build web applications. It supports HTTP/1.x and HTTP/2, as well as TLS/SSL encryption. HTTP.jl provides a routing system that allows developers to define routes for different HTTP methods and URLs. It also supports middleware, which allows developers to intercept and modify HTTP requests and responses.


Mux.jl is a lightweight HTTP server and router for Julia. It is built on top of the HTTP.jl package and provides a simple and easy-to-use interface for handling HTTP requests. Mux is designed to be fast, efficient, and easy to use, making it a popular choice for building web applications in Julia.

Mux also provides middleware support, which allows developers to intercept and modify HTTP requests and responses. This can be useful for adding features such as authentication, logging, and error handling to web applications.

Advantages of Julia for Web Development

Some of the advantages of Julia in the web development space are:

  1. Speed and Performance: Julia’s speed and performance are on par with languages such as C, making it suitable for building high-performance web applications.

  2. Interoperability: The ability of Julia to call in other languages is a huge advantage. Developers can easily integrate existing code and libraries into their web applications.

  3. Data Science Capabilities: Julia has built-in support for scientific computing and data analysis, making it well-suited for web applications that require these capabilities.

  4. Ease of Use: Julia's syntax is easy to read and write, making it easy for developers to learn and use for web development quickly.

Limitations of Julia for Web Development

Amidst the several advantages of Julia for web development, there are a couple of limitations that come with it. They include:

  1. Lack of Ecosystem Maturity: Julia's web development ecosystem is still in its early stages, so there may be limited support for web development tools and libraries.

  2. Limited Development Resources: There may be a limited pool of developers who are proficient in Julia for web development, which can make it more difficult to find experienced talent.

  3. Community support: Julia's community is still relatively small compared to other programming languages, which can make it more difficult to find support and resources for web development.

  4. Maturity: Julia is still a relatively young language. As a result, there may be some areas where it lacks the maturity and stability of more established languages for web development.


Julia is a language that has been primarily focused on scientific computing and data analysis, but we have seen how it can be used for web development. While the ecosystem and community support for Julia's web development is still growing, the language's active development and growing popularity suggest that it has a bright future.

With its unique features and advantages, Julia offers a fresh and innovative perspective on web development that is worth exploring for developers looking to create high-performance and innovative web applications.

Nice overview 👍

Another great web framework, not mentioned in the article but actively in development is Oxygen.jl. It feels very lightweight and has decent documentation.
