In this video we'll discuss how we can create typesafe REST APIs using ts-rest. This solution works for NestJS, NextJS, ExpressJS, and even Fastify APIs. With this solution we're able to consume the API on the client with a fully type-safe RPC-like client, leading to the best possible developer experience. This is a specially useful pattern if you happen to be developing your backend and frontend in monorepo. Must watch!

Thanks for this video. We build a pretty complicated application with multiple apis + projects and used trpc for it, but we kept on running into very hard to debug issues. This looks a lot better, since it still uses rest under the hood, so it's also trivial to debug. One disadvantage we faced with trpc was the difficulty in getting simple things, like web-hooks to work, since they use a very weird url pattern.

That's awesome thanks Marius. I was just starting to do the same, I guess manually, well building an SDK client side to interact with Nest that had schemas shared between the two, but this is great. Also the contract file made me think of I can do a similar thing for Firestore collection references shared between admin and client sdk. Yes, to more on this! NextJs or React would be great, with SWR or something similar as well

The reason why this is such a great pattern is because where the source of truth is. Docs are fine, docs are good but like tech books (exactly why tech books), they go out of date because they bit-rot. If you instead have this setup executing constantly, generated automatically, semver'd etc ... you'd have a method to maintain your API while creating clients. Pact is another way to do it, given different goals. But it works for the same reason. The best part of swagger is codegen to me but many people stop at doc gen. Trpc has similar ideas but then you'd have to gen a REST API and then wire that up to swagger and then gen a client. If I have a mobile app or a need for automation/interop, I think I would go with ts-rest first. Now the question is, does it work with Remix?! 🙃 Probably not or not yet. Honestly, this was the promise of express. "One language" but it didn't materialize (to me) because express was a microframework and TS (when express came out) didn't exist (iirc). Now, yeah, you have end-to-end type safety but you also have one language and types end-to-end which is new. The only limit is Javascript and what Typescript can't solve but I think even that can evolve with browsers. I don't know what the old alternative would be, plugins like Applets I guess but that idea didn't work out.

@mariusespejo 11 ай бұрын

Good thoughts! Just to answer the Remix question, I don’t think ts-rest is relevant there. They have a concept of “loaders” for routes which would be your data providers. There’s type safety built into using that so they already have that problem handled. And remix in general isn’t really designed for making REST APIs from what I can tell.

Awesome! Thank you for such a fantastic tutorial. I was thinking about implementing nesttrpcnext in monorepo, and now I believe achieving it using ts rest will be easier. But the only drawback I see now in comparison with trpc is that in ts rest contract, you describe the route, what happens if you don't implement (e.g., forget) it on the server side (nest.js) and try to use it in front (next.js)? In trpc, this scenario cannot happen.

@mariusespejo 11 ай бұрын

If you’re doing the multi-handler syntax it should enforce also server-side if there are missing methods in the contract. I actually showed that briefly in the video but maybe I didn’t explain well. So at build-time you should discover that something’s missing server-side if the contract got updated

@geebrox 11 ай бұрын

@@mariusespejo, yes, but imagine several contracts for different route layers (nest module controllers). If you do not create a controller for one of the contracts and implement a multi-handler for that module, after which you import that contract in FE and use it, you will only know about it when you face it manually, not even in the build time. I may be talking about too particular a scenario, but it may happen.

@mariusespejo 11 ай бұрын

Yeah that can happen totally, but I feel like more likely than not your first step after creating the contract is the implementation. I find it hard to imagine that your first step would be the FE consumption, but even if it was you’re bound to realize during development the api returns unexpected 404. I would hope that you’re testing it works even pre-build

I would personally dont recommend learning / using graphQL for a new project as of 2023, grpc is used in micro service environnments where they must communicate between them, there is a chance that your micro services are written in different languages depending on the goal of that service, grpc makes an interface language-agnostic to communicate, on top of a lot of optimizations such as using protobuf, ts-rest is nice for any js/ts api small / mid sized project

@mariusespejo 11 ай бұрын

Yeah good notes about grpc above, that’s a totally different use case. As for GraphQL vs REST, I still think it really depends. REST is still the standard that almost everyone will know. GraphQL requires a little more learning and setup for most people but it does help with giving clients more control of the response that they’ll get back. Not easy to define a simple answer in a comment lol. As for ts-rest, I think of it as just a utility to add to an existing REST api and is totally optional, it’s mostly for dev ux benefits if you’re working with typescript.

How is the performance in a large code base? I keep hearing that Zod can be painfully slow compared to alternatives like Typebox. I’m about to stand up a type safe backend and I’m leaning towards just sharing interfaces from a shared library to avoid ts language server overload.

@mariusespejo 11 ай бұрын

I would imagine that performance depends on your underlying framework (e.g. nest/fastify/express/next) not necessarily ts-rest itself. I also briefly mentioned that zod is optional (mostly if you want it to do the runtime validation for you), so you could strip that out and just use TS type/interface. The idea of sharing interfaces in a shared library totally works but that’s just one aspect of the full picture. You still need to make sure that you’re correctly typecasting your client-side api call responses. You’ll also notice with something like ts-rest it takes care of making your client dumb to what the api url paths are, what http verb to use, what http status codes can potentially return (something you’d usually have to assume client-side). You could also make an sdk in your shared library to handle all that, but then again you’re building all that manually vs just defining a simple contract

This is a very cool way to create APIs. But I still prefer the "pure contract-first" where you basically define yourself an OpenAPI Spec/Swagger upstream (OpenAPI/JsonSchemas are easier to write as zod schemas imo, and it has the same features!). This way, you have only one source of truth, you design your API before coding it. Which is very similar to ts-rest's approach, except, all your API consumers can use your API with type-safety no matter the language they're using.

@mariusespejo 11 ай бұрын

The core benefits from this idea is type safety during development time. It sounds like you’re trying to get an api schema at runtime which is sort of a different thing. However if you were to generate swagger docs, that comes with json you can pull down, e.g. if you had swagger docs at /api, the underlying json for those docs are accessible on /api-json … but don’t know that would be useful to you. If you want the type safety benefits then you should place the contract somewhere central, like in a library, where the client can install from. Or literally just copy/paste the contract code to each client but that would be a pain if you have a lot of clients

@Robytsu 5 ай бұрын

Thanks for this great video, Marius! There is just one thing I didn't understand: Where does the client get the contract from in a non-monorepo project? Does it get automatically generated just by hitting a server endpoint?

@mariusespejo 5 ай бұрын

Depends on your requirements. If it’s a public API you could publish the contract as an npm package. You also could install as private package from a private github repository. Worst case if none of those are options you could simply copy paste the contract between projects but not the best solution. The point here btw is the types that you get during development time, so generating from the server at runtime doesn’t really make much sense

@@mariusespejo Honestly, I have yet to use it myself as I just recently found out about it. However, I found the claims it makes very interesting. In my understanding, it lets you avoid doing the "vanilla" nestjs dance where you have to use a class instead of an interface, or use @Api* decorators to generate a more accurate swagger schema. Instead, it analyzes your nestjs code at build time to figure all that out automatically from your types. Then, you can generate a strictly typed client sdk client or swagger schema from that. As someone who likes using nestjs, that was the largest pain point for me. It is even illustrated by the author on the "pure typescript" section of the docs. But since I haven't had a chance to really use it yet, I was wondering if it does live up to all that. This why I was asking if you'd had a go at it.

@mariusespejo 11 ай бұрын

Looked at it briefly. So they are sort of trying to solve similar things just in a different way. E.g. they’re trying to reduce the amount of decorators when you have controller + swagger + class-validator… so they made their own decorators. But if you watched this video, you’ll notice ts-rest also indirectly solved that problem. Because you just define your schema in TS/Zod and you no longer need to use those decorators. Swagger docs is also auto generated off of that, you don’t even need to run any kind of generate command like with nestia. They (nestia) also generate an SDK for you it seems and that would help solve the similar type safety needs of a client. Still you need to run commands to generate it. Ts-rest is no codegen. It’s simple and it just works. Create a contract and import it on both server and client side and you’re done. No commands to run, no code you have to keep generating.

graphql on its own doesn’t solve type safety last I checked. You might use a codegen tool to generate types (similar to what prisma does), but you still have the overhead of importing those types and making sure to apply them in the right places on the client. Not to mention needing to make sure that you run codegen whenever the API changes. Server-side you also have a similar problem… you either have to write “code-first” using typescript so that you get types, or write “schema-first” and again generate the types. That seems like so much overhead compared to what I covered here. Correct me if I’m wrong.

You can create lazy loaded parameters, so you only fetch the information that you want and get relational data only if needed also from different services or databases. yes in overall its more on the server side but when you need more complexity it will pay of in the future. On the client side you can use like you mentioned codegens. So you dont have to write custom classes or types to deserialze your resulted json it will automaticly create that. Every graphql api has a schema file so you dont have to hope for a well made documentation.
