Thanks Jack. You saved me so much time by demystify the whole process, from setting up the development environment to wrapping up the project. Clean and effective code.
I watched half a dozen videos today on this topic and this is the first one where I understood how to use it and where its trade-offs are. Great tutorial.
Ok a lot of awesome stuff, great examples, excited to discover you and subscribe, etc., but... that transition at 21:26! Had to back it up and rewatch that a couple times! Haha nice work
Another fantastic video on new technology. Perhaps in pros/cons, on backend side trpc is only nodejs unlike REST, GraphQL, gRPC supported in most programming languages. Apologies if I missed that in the video. Really keen to try it out 🙂
Great love it! Reminds me a bit of my WCF adventures back in the days where I could just import a wsdl file (versioned) on the client and I had the models and type safety setup within a breeze. ❤️ This comes really close. 👍🏻
I do not have fond memories of wsdl. In general, a workflow that requires a bunch of code generation eventually runs into synchronization issues unless there's a lot of discipline (or it's just a single developer). Not saying it doesn't have its place (in C# I'm find of linq2db with T4 templating), but I think sharing types between client and server without code generation is better than wsdl. ...Well, after accounting for everything you lose by not being in a strongly typed environment.
Thanks for the vid, @jack. You are my fav. channel for getting react ecosystem news :D When you make a video about it, its about time to put it on the radar.
A-mazing content! I'm trying out the T3 stack and your video is incredibly helpful to understand trpc! question, shouldn't the onAdd query be auto invalidated because it suffered a mutation? I feel like forcing invalidation in the onSuccess callback shouldn't be necessary
Great video, nice and clear thanks ❤ I feel like you undersold the benefits of that e2e typesafety a bit 1 other downside to tRPC compared to REST/GraphQL/gRPC that you didn't mention is that unlike those others tRPC is only useful if both your FE & BE are TypeScript. Technically it probably also works with a JS frontend, but you'd lose the main benefit I'm really glad I stumbled on your channel, lots of great content I can share with team mates
I would say that tRPC is no worse than REST in that situation. gRPC is kind of a different story altogether because protos define everything and you can't get around the protos. GQL is different again in that there is runtime introspection, which neither REST nor tRPC (or gRPC) have. Anyway, I think tRPC is a no downsides upgrade on REST, but tRPC vs GQL or tRPC vs gRPC is a different story.
Excellent and clearly explained. Trpc's advantage seems to be in its simplicity and speed in terms of design. As long as you're in a monorepo and are using typescript, I think it's a great option.
Please, when u did npx create-react-app, it showed a bunch of option to select such as if u wanna use css or tailwind How do i get that to work on my pc as well?
It looks a lot like how we make graphql servers. What do you think would be better trpc or graphql server if we know graphql, as we can use the graphql schema to generate type safe code on the client using packages like graphql-code-gen
REST is an entity based model. Your model entities like user, product, and order. You can read, write, update and delete individual entities, and also get lists of that type of entity (e.g. all products.) But you can't get a joined set of entities in that model, for example, all the users that placed orders for a give product. That's why people created a REST API and then bolted on a set of reporting APIs to make up for the limitations of the REST API.
Jack, amazing content and great presentation. Thank you for covering the frontier of dev tools. A quck question: is there any materials in which you explain how to setup concurrently, wsrun and how to handle errors caused by these tools?
How would this work if the API source is in a completely different repo? What if the API is running and hosted on a different server from where the UI static files are served?
Yep. IMHO, GraphQL is a good fit for when you have a lot of flexibility on the frontend and the structure of queries may change a lot, or if you are providing a customer API (though that has some issues as well). If you don't fit either of those then something like tRPC is fine because you know the data you need at build time.
I love you give the github repo. There is alot to like about the trpc, fresh, deno stack. So moving my stuff over. Keep running into small issues, like do i need a mono for trpc etc. Love more on this stack together. Also what scales better gql or trcp for request etc? Or should i just go server api. We always talk about developer happiness. But i want whats best for my consumer.
What scales best... Depends on what scales means to you. In terms of load I think tRPC scales better because the per-transaction costs aren't as high. IMHO, if you are offering API as as service, then go with GraphQL, if you are building both the server and the client, use tRPC.
Thanks Jack. It's a great video. One thing that I need to know is that tRPC can run at the Edge like in Cloudflare Workers, Deno Deploy, Fastly Compute@Edge, others... Recently I have started using Cloudflare Workers with Solid Start (The Awesome Solid.js Meta Framework) & Deno Deploy with Oak & Faunadb. as a result, the whole thing is fast. Building API's & SSR (with HTML Streaming) at the Edge is Really Awesome 👍😎.
- error ``` Error: Debug Failure. False expression: Non-string value passed to `ts.resolveTypeReferenceDirective`, likely by a wrapping package working with an outdated `resolveTypeReferenceDirectives` signature.

Great video as always! I learned something new every time and trpc is so cool! I've always found sharing types with the front and back end such a pain. Not to pick nits though: isn't it the browser that enforces CORS? That's a security mechanism that always mystified me...
@@DanKaschel I wasn't really confused by how it worked, just that it's so easy to write a proxy that enforces a different set of CORS rules, makes that protection useless against all but the least savvy would be API theives. I'd be happy to learn otherwise...
@@jasonthorpe3470 an important feature of cors is to protect requests using cookies. If you create a proxy you will have a different origin so the browser won't send the same cookies. If the api doesn't use cookies, then there isn't much security benefit to cors
Hey really cool vid as usual. I'm picking some new stuff thanks to you. I have two question:s I see that you use ScreenFlow and I like the effects. Any resources to look at to learn more? I want to make nice videos as well. And what do you use to draw on the screen? I saw you were looking down while doing that. Thanks!
Well another Con agains GraphQL is that it can't choose what it will be sent to the client, cause in tRPC, what you have on your query is what is going to be sent, right?
Hey Jack! I'm curious about creating the trpcClient as state here. Why would this be required as opposed to, for example, useCallback? Would this still work? Can you think of any reason to prefer one over the other?
@@mmmikem Well, it's not a function, so I wouldn't use `useCallback` but you could use `useMemo` if you want instead, though as some folks have said the docs state that in the future React reserves the right to flush memos to recover space. Or you could use a `useRef` for this, but then you'd need to say `trpcClient.current`, which is not exactly a game changer. Frankly you could probably just pull this out of the component altogether and just define it at the top of the file. I'm not 100% sure why I found it necessary to define it in the component here. As you say, it has been a while since I did this video. Lots of interest in TRPC tho!
@@jherr ah of course - it's the return of the function that we care about. Oddly enough, I'd thought about whether it *might* need to be invoked inside the component if it was relying on hooks somewhere in there. I feel as though, if that works, it'd be the simplest/cleanest option, as it'd be colocated with the RQ client? I'm gonna give this a bash and see! Thanks for taking the time to respond, really appreciate it!
i notice a lot of hype about trpc lately but i havent figured out and havent tried it myself yet. is this also beneficial for java backends ? i have very limited fullstack experience and dont know what server this is supporting
No, this wouldn't benefit the Java backend world. The idea here is that tRPC is TypeScript on both ends of the pipe, so it makes it easy to define your object types once and use them in both places.
Thanks Jack! I have my cross feelings about TRPC. Why would anyone would like to make a non-language agnostic API? So if I'm a python dev, I will have to first learn TS and then TRPC to consume the API?
tRPC is great but there seem to be a lot of unnecessary complexities. Telefunc is probably a more literal RPC. Would be fun and helpful to see you try it.
Hey Jack, this video is really helpful and has gotten me more interested in tRPC and typescript. One small thing that left me a little confused is that when you connected the api-server with the client, while this works for the dev process, how would this pan out during deployment? The client would not be able to access the api-server package as it only exists in the local env... Would adding the server as a dev dependency yield the same result?
Very good question. You not actually importing any code between the 2 apps. Your simply importing types. In production the types are compiled away. Under the hood trpc makes an http call with the route names. So it's not like the files need to be collocated at all. Ps. We been using trpc for over a year now with Prisma and next and we're hiring.

I kind of get the same feeling that I got when I first saw Redux. I was in awe when I saw the time-travelling feature, but I couldn't help but thinking that it was kind of cumbersome to set-up for the value. Maybe they'll improve the API or the general DX in future releases. All in all, I'm not sure to get the full value of tRPC? Maybe I was so hyped before reaching this video, with so many people singing it's wonders of and swearing by it, that it was easy to feel kind of disappointed.
I wonder why devs decided to create a trpcClient with useState hook. Why not just create it the same way as react query client... I checked tRCP docs, I don't know. I checked your code as changed it, nothing broke, everything still works. Feels like trap, but I think it should be just fine, at least in this case. Maybe it has something to do with async stuff and the new React use hook , I don't know
It depends on what. you mean by REST. REST isn't a standard. It's an "architectural style". And the only specific thing it covers is the basic verbs associated with entities and collections and the hierarchal relationship between them. Generally speaking REST is both incomplete in that it doesn't allow for one query that involve more than one entity or collection at a time, and also incorrectly structured because the hierarchy of the entities doesn't allow for important permutations of queries. I usually see REST coupled with a set of RPC endpoints. And people just call that "REST" when it's not really anything "standard". Every team/project/company just comes up with their own standards. tRPC is a standard (though not as well specified as GraphQL) and it provides easy end-to-end typing.
@@jherr What I mean is that the things you did in the video, seems like I can do all of them with bare ExpressJS with the same amount of effort, and probably even less amount of code. That's what I am not sure why I need tRPC for my project.
Hy Jack, Excellent content as always, but I'm always wondering what is your opinion on NodeRed low-code, because I'm amaze with how NodeRed handle business-flow. can you give me one or two opinions on this. thanks so much Sensei.. 🥳
Feels like tRPC's assumption about having typescript in the backend is a major limiting factor for it. I did notice a few Rust crates in early stage but unless other languages are designed to support it ... and TS as a type system is amazing for JS but maybe not what you want to marshal to with other languages. For now, I'd say gRPC's relative maturity and multi-language binding makes it a better choice for most RPC projects.
I agree with your issues with TS and other languages. But gRPC is no picnic either. I use gRPC every day and the TS generation is pretty flaky. And some of the data type marshaling has issues. Also you have to proxy gRPC it to web clients. So I end up wrapping my gRPC in GraphQL.
@@jherr surprised to hear about the marshaling issues with gRPC but I will admit I don't have a lot of hands on with it ... would have thought a solution in the market as long as gRPC would have worked out all of these kinks. Do you use Zod for validation on the gRPC setup? Seems like that would help in assurances for run time type checks.
@@yankee-in-london I don't use Zod for that. The generated TS is good types wise. The marshalling thing comes down to number values. If the number is undefined it still returns zero. So I end up hand code special casing every field that could be nullable, which kinda sucks. I should probably wrap it to make it generic... Ah, well.
The (obvious) con of tRPC: It requires running TypeScript on the server. So for many teams, that rules it out. That's why GraphQL is so popular - it's a standard that isn't tied to a specific server-side language. But if you're using TypeScript on the server, tRPC a wonderful option that's simpler than GraphQL.
With HTTP2 and the rise of DaaS I do wonder if the value of websockets is as high or broadly useful as it once was. It feels like web sockets is possibly better for niche situations nowadays

How would this work if the API source is in a completely different repo? What if the API is running and hosted on a different server from where the UI static files are served?
You'd generate into a shared npm module, or generate into the server module and have the client app consume whichever shared module you created.

It depends on what. you mean by REST. REST isn't a standard. It's an "architectural style". And the only specific thing it covers is the basic verbs associated with entities and collections and the hierarchal relationship between them.
Generally speaking REST is both incomplete in that it doesn't allow for one query that involve more than one entity or collection at a time, and also incorrectly structured because the hierarchy of the entities doesn't allow for important permutations of queries.
I usually see REST coupled with a set of RPC endpoints. And people just call that "REST" when it's not really anything "standard". Every team/project/company just comes up with their own standards.
tRPC is a standard (though not as well specified as GraphQL) and it provides easy end-to-end typing.
@@jherr What I mean is that the things you did in the video, seems like I can do all of them with bare ExpressJS with the same amount of effort, and probably even less amount of code. That's what I am not sure why I need tRPC for my project.
@@ziranshuzhang6831 You might not. If you don't think that tRPC adds anything then don't use it.
Hy Jack, Excellent content as always, but I'm always wondering what is your opinion on NodeRed low-code, because I'm amaze with how NodeRed handle business-flow. can you give me one or two opinions on this. thanks so much Sensei.. 🥳
Could you please update this video using tRPC V10? Thank so much for your valuable videos!
Feels like tRPC's assumption about having typescript in the backend is a major limiting factor for it. I did notice a few Rust crates in early stage but unless other languages are designed to support it ... and TS as a type system is amazing for JS but maybe not what you want to marshal to with other languages. For now, I'd say gRPC's relative maturity and multi-language binding makes it a better choice for most RPC projects.
I agree with your issues with TS and other languages. But gRPC is no picnic either. I use gRPC every day and the TS generation is pretty flaky. And some of the data type marshaling has issues. Also you have to proxy gRPC it to web clients. So I end up wrapping my gRPC in GraphQL.
@@jherr surprised to hear about the marshaling issues with gRPC but I will admit I don't have a lot of hands on with it ... would have thought a solution in the market as long as gRPC would have worked out all of these kinks. Do you use Zod for validation on the gRPC setup? Seems like that would help in assurances for run time type checks.
@@yankee-in-london I don't use Zod for that. The generated TS is good types wise. The marshalling thing comes down to number values. If the number is undefined it still returns zero. So I end up hand code special casing every field that could be nullable, which kinda sucks. I should probably wrap it to make it generic... Ah, well.
you are doing great
The (obvious) con of tRPC: It requires running TypeScript on the server. So for many teams, that rules it out. That's why GraphQL is so popular - it's a standard that isn't tied to a specific server-side language. But if you're using TypeScript on the server, tRPC a wonderful option that's simpler than GraphQL.
Did you just import server code into client code? I know... tree shaking and this is just a quick demo and all but... my eyes are burning 🔥
At what time marker?
very kool
With HTTP2 and the rise of DaaS I do wonder if the value of websockets is as high or broadly useful as it once was. It feels like web sockets is possibly better for niche situations nowadays
