Express vs tRPC: Which One for Production?
Express has over 57,000 GitHub stars. tRPC, on the other hand, doesn’t even crack the 10,000 mark, and honestly, stars don’t ship features. Let’s break down these two frameworks and see which is worth your time and energy for production applications. The ongoing debate in the development community between Express and tRPC can be quite intense, but this is a discussion you need to have, especially if you’re planning to ship a serious application.
| Framework | GitHub Stars | Forks | Open Issues | License | Last Release Date | Pricing |
|---|---|---|---|---|---|---|
| Express | 57,000 | 13,000 | 50 | MIT | September 2022 | Free |
| tRPC | 9,400 | 794 | 12 | MIT | March 2023 | Free |
Express: The Classic Choice
At its core, Express is a minimal and flexible Node.js web application framework that provides a set of features for web and mobile applications. It allows you to create a variety of web applications, APIs, and servers with minimal overhead and configuration. It is particularly favored for its simplicity and versatility, making it a go-to starting point for many Node.js applications.
const express = require('express');
const app = express();
const port = 3000;
app.get('/', (req, res) => {
res.send('Hello World!');
});
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`);
});
What’s Good About Express?
For starters, Express has been around since 2010. With a stable API and a huge library ecosystem, developers can easily find middleware and plugins to extend functionality. Do you need authentication? There’s a middleware for that. Want to parse JSON? Easy. Express also works with various databases; you aren’t locked into any one database system.
The amount of community support is staggering. There are countless tutorials, GitHub repositories to learn from, and tons of middleware to streamline your app’s functionality. Want to bolt on a session manager or looping middleware? You can find them at the click of a button. Plus, its minimalist design gives you complete control over your stack. This is power—it’s like building on a Lego set rather than a pre-built model. Change anything on your app without feeling like you’re violating someone else’s philosophy.
What Sucks About Express?
But it isn’t all sunshine and rainbows. There’s a learning curve—particularly with middleware and routing—if you’re not already familiar with the Node.js ecosystem. Managing asynchronous calls can get clunky, and callback hell is real, even in a minimalistic framework like Express. It’s something many new developers run into, and while there are workarounds (such as async/await), it can potentially trip you up if you’re not careful.
Also, Express doesn’t enforce a structure. While flexibility can be a boon, it can quickly become a curse. In larger projects, not having a set convention can lead to a franken-code situation. It’s common to see developers arbitrarily trying to enforce rules on their own, often leading to inconsistencies that get painful when teams scale.
tRPC: The New Kid on the Block
Now, let’s turn our attention to tRPC. Unlike traditional frameworks like Express, tRPC is a type-safe RPC (Remote Procedure Call) framework for building APIs. Basically, it simplifies the process of creating and consuming APIs in a TypeScript environment by facilitating end-to-end and type-safe APIs without needing a separate client for data fetching. This brings some powerful features to the table—especially if you’re in the TypeScript ecosystem.
import { initTRPC } from '@trpc/server';
const t = initTRPC.create();
const appRouter = t.router({
getUser: t.procedure.input(z.string()).query((opts) => {
return getUserFromDb(opts.input);
}),
});
export type AppRouter = typeof appRouter;
What’s Good About tRPC?
For starters, tRPC shines in its type safety. With tRPC, you get both front-end and back-end typed, meaning you can catch type errors during development rather than at runtime. If you like TypeScript, this will feel like a breath of fresh air and make coding a whole lot smoother. Also, it’s designed for full-stack environments, which means no need to write separate API clients. If your team is developing a TypeScript-centric application, this framework reduces the complexity you’ll usually find with a REST or GraphQL setup.
Another big plus is its speed. tRPC is lightweight and doesn’t have the overhead that comes with more traditional frameworks, especially when it comes to handling requests. This can be a significant advantage if you’re building an app that needs to scale rapidly.
What Sucks About tRPC?
Trouble is, tRPC is relatively new. While this means it has a lot of potential, it also raises concerns around maturity and community support. Since it’s less established, you’ll find fewer tutorials, lesser-known edge case solutions, and if you run into a unique problem, you’re probably going to have a harder time finding answers.
You may also run into integration issues with other libraries and frameworks. Integrating with things like authentication libraries can take quite a bit of elbow grease, and while this may improve in the future, existing solutions may not fit perfectly with what tRPC is offering. Plus, if your team isn’t as familiar with TypeScript, you might find yourself in hot water.
Head-to-Head Comparison
Performance
tRPC is the clear winner here. The architecture is optimized for performance over traditional RESTful APIs. With tRPC, you’re directly calling functions which means less overhead. Express serves an entire HTTP request/response cycle which does slow things down.
Type Safety
Another win for tRPC. Since it enforces type checking across the stack, you’ll see fewer runtime issues that are common with Express applications where types are based on runtime characteristics rather than compile-time checks.
Community and Maturity
Express dominates in this category. With over a decade of presence, its community support and available resources dwarf tRPC. When you get stuck on something in Express, a quick Google search generally yields results almost instantly. Remember, large projects may not have the time for tRPC’s smaller support base.
Flexibility
Express takes the crown. The sheer number of libraries and options available mean you can mold it to fit your needs better than tRPC, which is much more opinionated in its approach. If you want to control every aspect of how data flows in your application, Express gives you the keys.
The Money Question: Pricing Comparison
Both Express and tRPC are free to use, and they’re licensed under the MIT license, making them accessible for commercial usage. However, keep in mind that hidden costs can arise depending on the ecosystem you build around it.
In a real-world application using Express, you might need to borrow libraries for things like validation, error handling, or even specific database interactions, leading to additional maintenance costs. For a large team, this could translate into developer hours used to wire everything together.
For tRPC, while you have all the benefits of being type-safe and integrated, the cost really comes into play when considering the learning curve if your team is new to TypeScript. If your developers need significant training or onboarding, that’s an investment worth considering in your total cost.
My Take
If you’re a solo developer, trying to act fast, go for tRPC. It’s fast, has type safety, and eliminates the hassle of building a REST API that you’ll likely outgrow quickly. However, understand that you may need to put in some extra effort to get comfortable with TypeScript.
If you’re part of a larger team working on a web application, Express is the winner. The community support and resources available will save you time and effort in the long run. Plus, the maturity of Express means you can easily integrate existing solutions from a multitude of libraries.
If you’re working in a legacy system with defined architectural boundaries already in place, stick with Express. Bringing in tRPC could disrupt existing structures of your application unless you’re ready to rebuild it completely in a more modern structure.
