NestJS gRPC Microservices Tutorial

[@thisisrohan6444]

For Windows user : npx protoc --plugin=protoc-gen-ts_proto=".\ ode_modules\\.bin\\protoc-gen-ts_proto.cmd" --ts_proto_out=./ --ts_proto_opt=nestJs=true ./proto/auth.proto

Thx

[@mister-med]

You truly are the Messi of NestJS.. Thanks for sharing your knowledge with us! 🙏

[@mcoria74]

The way you fix and improve the code is amazing, maybe in my next life I'll learn NestJS... like you.

[@dlsrios]

Thank you, bro! I was looking for some examples of using gRPC with streams, and your explanation was great! 💪

[@abolfazljalildoost766]

can't find better than you in Nestjs. thanks for your useful contents ♡♡

[@joewhiteakeriii5568]

I love the lane of content that you post man. I am a huge fan of using nest js and containerization, so your content has been a huge source of inspiration to learn more into things like this

[@adR9990]

Can you please start providing an architecture diagram of what you are trying to code at the beginning of the video, using Excalidraw or something? It will help viewers visualize what is actually being built.

[@mguay]

Sure. Thanks for the suggestion.

[@johnholanda7798]

nice video, the only video that I learned well about gRPC and nest

[@nbaua3454]

OMG, I guess I am in great luck today.. I was about to work on these feature on Monday and this video just popped up on 🔥🔥🔥

[@AnlGUNDAL]

Thanks a lot. I learning microservises with you from udemy and youtube.

[@blender_wiki]

Very nice add to existing content in you full course. 🙏🙏🙏

gracias bro, llegaré lejos con tu ayuda!

[@xDiggie]

Very helpful! I actually managed to finish the tutorial. Now that I'm back messing around my own personal project, I just have a quick question. Is it possible to await response from a microservice? I basically have a loading UI when a task is ongoing ( saving objects to db) and while I want it to load while awaiting the task to finish and get a response from the microservice (to use that response on the page after the loading UI), I also need the event loop to not get blocked in the process. Does microservices solve this? or would there be a better solution for this. Any reply or a direction would be greatly appreciated. Thanks!

[@jomelortega7902]

Sounds like an optimistic response from UI (manually altering the current data displayed while waiting the response from backend), Backend shouldn’t care about this

[@EthanPhan-m2w]

Thanks for sharing.

[@overrevvv]

Thank you for this amazing video.

[@NathanielBabalola]

Can you please split this into different repos and show how you'd handle the sharing of different proto files between different projects . I think that's where the issue is.

[@sadhakbj]

Totally agreed.

[@theeaster2839]

That’s the default multiservices problem. Use cloud storage, or private npm

[@MateoC-f4n]

well in that case you'd use something else lol. the point of using nestjs and this setup is that you can have everything in one place. If you're going polyrepo, best of luck not losing your mind.

[@NathanielBabalola]

[@sadhakbj]

This was something that i wanted to request you for our microservices course, you created a video wow. Will you add a small section in our existing microservice course?

[@mguay]

Yes that is next! Thanks for your support.

Brilliant video.

I am confused about the apigateway part in the microservices. Are we supposed to write users module there? Thanks for the video.

I couldn't follow again after running the protoc command because it errored out: protoc --plugin=./node_modules/.bin/protoc-gen-ts_proto --ts_proto_out=./ --ts_proto_opt=nestJs=true ./proto/auth.proto proto/auth.proto:28:1: Expected top-level statement (e.g. "message").

[@deepaihub]

which version number using protoc cli, latest version not find in auth.ts user service controllers

[@whalewalker9176]

If you're using macOS and encounter the error 'zsh: command not found: protoc' while attempting to execute the command 'protoc --plugin=protoc-gen-ts_proto=./node_modules/.bin/protoc-gen-ts_proto --ts_proto_out=./ --ts_proto_opt=nestJs=true ./proto/auth.proto', you can resolve it by installing the Protocol Buffers compiler. Simply run 'brew install protobuf' assuming you have HomeBrew installed on your Mac. This will install the necessary compiler and resolve the issue.

[@oguejiofordaniel9871]

I did this, and now the content of my generated file is totally different from his own. Did you encounter that too?

[@michaelserikov9339]

Hey! Love your video, thanks! I came over one question during development, hope you will answer on it: by following conventions, where Data Transfer Objects can be used in application? Which layers? Or such kind of entities can be accessible through all application's layers? What is the best practice for DTOs?

[@mr_ehmed]

best love it

How to handle exception properly on the apigateway? like find one user which is already deleted, the response is 500 instead of 404. But the auth app correctly throw NotFoundException

[@mak8naf0813]

how can I catch errors thrown from the auth service on the API Gateway side? I know I should use exception filters, but I've tried several ways and it still doesn't catch the errors.

[@GuilhermeFaxina-r5q]

[@stancobridge]

What about situation u want to use multiple protofiles

[@nguyenchauthaoquan4836]

Can we let API gateway communicate with the other microservices by gRPC way as well ?

Hi, do you have twitter? how do you learn or follow about all the different tools/packages that you use, for example? keda, artillery etc.

gosh that's alot of manual setting up, is gRPC that new on the market? Great explanations though, so clear👌

protoc is not available on windows, you might want to do the development on WSL

But yeah, dunno if there’s an existing alternative that does the same thing as protoc

Why are you using streams to receive users why would you not use the pagination approach? Imagine if there are thousands of rows in database will u send all of it to consumer?

[@kamalkamals]

i guess it s better to generate types atomically instead manually

Why pnpm

[@PavleJovanovic-gn3jw]

It's much faster than npm, especially on warm starts, and it manages the packages better.

[@johnaadepoju]

You will have to use the full path instead. For example: protoc --plugin=protoc-gen-ts_proto="C:\path\to\your\project\folder ode_modules\.bin\protoc-gen-ts_proto.cmd" --ts_proto_out=./ --ts_proto_opt=nestJs=true ./proto/auth.proto
