Svelte was built on “slinging code for the sheer love of it”

Key takeaways

Svelte was born from the challenges of earlier web development frameworks, aiming to simplify and streamline the development process.
Simplicity in Svelte is an aspirational goal that influences both its design and the developer experience.
Managing asynchronous operations remains a significant challenge in web frameworks, and Svelte is working on improved solutions.
The future of open-source projects like Svelte will likely involve greater corporate investment to ensure sustainability.
Community contribution is crucial to Svelte's continued development and success.

Summary

The Genesis of Svelte

Rich Harris shares the backstory of Svelte's inception, revealing how his career in software began due to the financial recession of 2008, prompting him to enhance his employability by learning coding. The development of Svelte was driven by a need for better tooling in web development, particularly the challenges he faced in creating interactive visualizations in the early 2010s. Harris highlights the evolution of technology and the 'Cambrian explosion' in web frameworks that led to the birth of Svelte, born out of necessity and a desire to simplify the development process.

Simplicity and Design Goals of Svelte

The discussion pivots to Svelte's design philosophy, focusing on simplicity not necessarily as a design goal, but as an aspiration born out of wanting to make the authoring experience natural and intuitive. Harris explains the compiler aspect of Svelte and how it aims to reduce JavaScript bundle sizes while enhancing the developer experience, which drives its popularity.

Asynchronous Operations in Frameworks

A significant portion of the conversation revolves around the challenges of managing asynchronous operations within web frameworks. Harris discusses how traditional component frameworks struggle with asynchronous tasks and the potential solutions being worked on within Svelte. The team aims to improve how asynchronous data is managed across components, moving towards a more coordinated and seamless developer experience.

The Future of Open Source and Svelte's Roadmap

Rich Harris discusses the future of open-source contributions and Svelte's growth, noting the importance of more companies investing in such projects. The roadmap for Svelte includes recent significant upgrades and an exploration of remote functions for a smoother async data handling experience, enhancing development efficiency.

Community and Maintenance of Svelte

Harris shares insights about his role as one of the maintainers of Svelte, outlining the collaborative nature of maintaining an open-source project. He emphasizes the community aspect of Svelte, which contributes significantly to its development, and explores the balance between professionalization and the cherished community spirit of open source.

Show notes

Rich Harris, creator of Svelte and software engineer at Vercel, joins Ryan on the show to dive into the evolution and future of web frameworks. They discuss the birth and growth of Svelte during the rise of mobile, the challenges of building robust and efficient web applications, how companies can back more open-source community projects, and the dirty little secret about asynchronous operations and component frameworks.

Episode notes:

Svelte is a UI framework that uses a compiler to let you write components using HTML, CSS and JavaScript. It’s ranked as one of developer’s most admired web frameworks in this year’s Developer Survey.
