Why I’m Betting My Next Project on the Framework Nobody Talks About
After fifteen years of watching JavaScript frameworks rise and fall like cryptocurrency prices, I’ve developed a sixth sense for spotting the ones that actually solve problems instead of creating new ones. Most frameworks promise the moon and deliver a debugging nightmare. But every once in a while, something comes along that makes you question why we’ve been doing things the hard way for so long.
That framework is Solid.js, and it’s been slowly changing how I think about reactivity while the rest of the industry argues about whether hooks were a mistake. Created by Ryan Carniato, Solid takes the best ideas from React’s component model and throws out everything that makes React slow, unpredictable, and occasionally soul-crushing to debug. The result is a framework that feels familiar but performs like it’s from the future.
I’ve spent the last six months migrating a performance-critical dashboard from React to Solid, and the results have been so dramatic that my product manager actually asked if I had secretly upgraded our servers. Spoiler alert: I hadn’t. The application just runs that much better when your framework isn’t fighting you at every render cycle.
The Architecture That Actually Makes Sense
Solid’s secret weapon isn’t some clever marketing trick or venture capital hype. It’s a fundamental architectural decision that most other frameworks get wrong: true fine-grained reactivity without a virtual DOM. When your state changes in Solid, only the specific DOM nodes that depend on that state get updated. Not the entire component tree. Not some arbitrary subtree. Just the exact pieces that need to change.
This isn’t just theoretical performance optimization. In React, when you update a piece of state, the framework has to run your component function again, diff the virtual DOM tree, and figure out what actually changed. It’s like rewriting your entire grocery list every time you need to add milk. Solid skips this elaborate dance. When a signal updates, it directly notifies the DOM nodes that care about that value. The component function runs once during initialization, sets up these reactive connections, and then gets out of the way.
The mental model shift took me about a week to fully internalize, but once it clicked, I found myself writing components that were both more performant and easier to reason about. No more useCallback and useMemo scattered everywhere like defensive programming talismans. No more wondering whether that innocent-looking state update will cause a cascade of unnecessary re-renders three components down the tree.
Where Solid Quietly Demolishes the Competition
Let’s talk numbers, because performance claims without data are just marketing fluff. In my dashboard migration, I replaced a React component that was rendering 500+ rows of financial data. The React version, even with React.memo and careful optimization, would occasionally stutter during rapid updates. Users noticed. Support tickets were filed. The Solid version handles the same workload without breaking a sweat, even on devices that struggle to run Slack without thermal throttling.
But raw performance isn’t the only place Solid shines. The developer experience feels like what React promised before it got complicated. Components look familiar enough that my team picked up the syntax in an afternoon, but the underlying reactivity model eliminates entire categories of bugs. No more stale closures. No more dependency arrays that lie to you. No more useEffect chains that make you question your life choices.
Solid’s JSX implementation is another quiet revolution. Unlike React, where JSX is syntactic sugar over function calls that create virtual DOM nodes, Solid’s JSX compiles directly to DOM operations. This means your templates are actually templates, not functions that run on every render. The compiler optimizes your JSX at build time, turning declarative code into imperative DOM updates that run as fast as hand-written vanilla JavaScript.
The Ecosystem Reality Check
Here’s where I need to be honest with you: Solid’s ecosystem is still growing. You won’t find a Solid equivalent for every React library you’ve grown dependent on. If your project relies heavily on a mature ecosystem of third-party components and tools, jumping to Solid right now might feel like trading a Swiss Army knife for a really good knife that’s just a knife.
That said, the core libraries you actually need are already there. Solid Router handles routing with the same level of sophistication as React Router. SolidJS Store provides state management that makes Redux look like an over-engineered museum piece. The community is small but incredibly focused, and the quality of available packages tends to be higher because the people building them understand the framework’s philosophy.
What’s particularly encouraging is how quickly high-quality solutions emerge when someone identifies a gap. The Solid community seems to attract developers who care more about elegant solutions than recreating every React pattern in a new framework. When someone builds a Solid library, it’s usually designed to take advantage of Solid’s strengths rather than papering over its differences.
Making the Strategic Call
The question isn’t whether Solid is better than React in a vacuum. It’s whether Solid is better for your specific situation right now. If you’re building performance-critical applications, handling lots of dynamic data, or just tired of fighting React’s complexity, Solid deserves serious consideration. The learning curve is gentle enough that you can prototype a component in an afternoon and get a real feel for whether it clicks with your team.
I’m not suggesting you rewrite your entire React codebase tomorrow. But for new projects, especially ones where performance matters and you can afford to be slightly ahead of the curve, Solid offers something genuinely different. It’s what React could have been if it had started with fine-grained reactivity instead of retrofitting performance optimizations onto a fundamentally inefficient model.
The framework landscape changes fast, but the underlying principles that make Solid compelling will probably stick around. Fine-grained reactivity isn’t a trend, it’s a better approach to building user interfaces. Solid just happens to be the framework that got the implementation right while everyone else was busy chasing the next shiny thing.
If you’ve been curious about alternatives to React but skeptical of frameworks that feel like science experiments, give Solid a weekend. Build something small but interactive. Pay attention to how the reactive model feels different from what you’re used to. I’d be genuinely curious to hear whether you have the same “where has this been all my life” moment that convinced me to write this article in the first place.
