React Router vs TanStack Router

React Router is the default choice for most React developers. It works, it’s stable, and everyone knows how to use it. TanStack Router is newer, type-safe, and frankly, a bit more opinionated.

Why change what isn’t broken?

“React Router is already installed everywhere, so why would I bother switching?” This is a valid objection. If you have a massive codebase already using React Router, moving to TanStack Router is a significant amount of work for little immediate gain. You’re right to be cautious. However, if you are starting a new project, the tradeoffs change quickly.

Type safety matters

TanStack Router provides end-to-end type safety for your routes. You don’t have to manually define route strings. If you want to link to a page, you get autocomplete and error checking out of the box.

<Link to="/posts/$postId" params={{ postId: '123' }}>

  View Post
4
</Link>

In React Router, you might be typing strings manually and hoping for the best (or maintaining a complex map of constants). TanStack handles this via generated types.

What about data loading?

“I like how React Router handles loaders.” I agree, their loader pattern is great. TanStack Router uses a similar approach but integrates it deeper into the routing lifecycle. It handles data fetching and caching with a focus on avoiding layout shifts. It feels more deliberate.

Is it all sunshine?

To be fair, the learning curve for TanStack Router is steeper. The build step required to generate the route manifest can be a headache in some environments. Sometimes I wonder if it adds too much complexity for small apps (honestly, for a landing page, both are overkill).

If you prioritize type safety and want to catch broken links at build time, look at TanStack Router. If you want the fastest path to shipping a feature without learning a new API, stick with React Router. I’m still using both depending on the team’s familiarity. There isn’t one objective winner here. Choose what keeps you moving.
