Micro-services with auto discovery, observability and load balancing. | Rethink Connectivity Ep 9

[@mileshill4804]

I've watched this 4 times now. About to push this pattern into our future rollouts. Edge microservices!

[@90hijacked]

i find it crazy how many features nats has, in a positive/obsessive way

[@MrOohBattman]

Great video. I'm missing the 'micro' option in my cli tool though. I've updated 'nats-tools' and 'nats' on mac, is there a nightly or another version I'm missing?

[@SynadiaCommunications]

This has finally been released in the CLI as of v0.1.0.

[@AhmadShrif]

I do not see the scheme supported on the latest nats, did they drop it?

[@JohnMcclaned]

If this took a vercel like approach and really focused on the developer experience with an observability + admin dashboard (basically a nats-cli dashboard), it would be so much easier to get started and see the benefits.

[@SynadiaCommunications]

Agreed. We are working on an experience like that at Synadia :)

[@JohnMcclaned]

@@SynadiaCommunications Exciting, I will be following the progress :)

[@marvinlnnx]

Hi, Thanks for the video, it is really informative, it's look like in the current version SCHEMA is deprecated or maybe replaced by something else , not sure , because I need to scan the request to a particular struct in golang and also make sure the response will be scanned into an appropriate struct so the caller can scan it and utilize it , json.Unmarshal does not return error in my case when the request does not look like the struct ! I wish nats micro could have come with this feature to guarantee the req and resp struct

[@SynadiaCommunications]

We removed the schema field present in the prerelease versions if micro in favor of our more generic `metadata` struct for endpoints and services. You can add a `schema` field to that and essentially get the same benefit

[@michaelkobaly2378]

Am I missing something. The current Nats CLI (0.0.35) does not have the micro command.

[@SynadiaCommunications]

Yes, we will be releasing it very soon alongside a new version of NATS, but you can install from the main branch to get access to the micro command today

[@sonuselva]

where can i find the reference code given in this video?

[@Cbon-xh3ry]

What are Q and Q Lang ?

[@scottamolinari]

Hey Jeremy. The schema stuff in micro have been deprecated and replaced by "metadata". Can you do a video on how to use this in a similar way as was possible with the schema API please?

[@SynadiaCommunications]

Hey Scott. You would essentially use it the same way. Add a schema field to your metadata and look that field up to get the schema

[@suikast420]

Looking great. How nats micro related to jetstream?

[@peterpetersky2152]

Is this nvim that you're using? Looks awesome. Greets from an Emacser!

[@pablovicentico]

This awesome. It would be good for example code to be shared in the description so we can experiment and get familiar faster 😊

[@SynadiaCommunications]

There are two examples up on NATS by Example for Go and JavaScript: natsbyexample.com/examples/micro/intro/go

[@Cbon-xh3ry]

Why is it in a different repo ? it should be part of nats

[@marvinlnnx]

What type of NATS server is applicable for this pattern ? I am using NATS JetStream with 3 servers, can I can also use it for service implementation and communication ? By the Schema is deprecated and no longer exist, I wish you could have provide a more practical and generic example (whereas service can make a call as well in your example you are using NATS cli to make a call) in the updated video which everyone is expecting it. and Thank you so much for connectivity pattern to NATS. it is really amazing.

[@SynadiaCommunications]

This implementation works with any NATS server, as all of the functionality is handled by the clients themselves

[@PrakharMishra150290]

I liked what you can achieve with NATS. It really feels like an upgrade of messaging systems. I have one question though, can this microservice be accessible to external / third party service, or maybe web browsers running react? If its possible with authorization, its really awesome...

[@SynadiaCommunications]

Absolutely! Web browsers can connect via websockets using the nats.ws library. It uses all the same mechanisms for auth

[@enochabassey2786]

Very very awesome approach here.

[@SynadiaCommunications]

Glad you think so!

[@shadowfaxenator]

Is nats The only transport supported now ? No way to support http ?

[@SynadiaCommunications]

Currently it’s only for NATS, but it wouldn’t be too difficult to build a process that could forward NATS traffic to an http service

[@pss_crs]

can you mention that plugin auto fills structs

[@SynadiaCommunications]

Just the golang LSP, using codeactions

[@pss_crs]

@@SynadiaCommunications You helped me a lot dear, thanks 😊

[@tomask6]

Which kind of IDE is that? Looks like a full pimped vim environment.

[@SynadiaCommunications]

Yes! It’s Neovim and kitty for the terminal

[@Esteban-ou5yn]

@@SynadiaCommunications any chance you'll share your neovim rc somewhere? :) your dev environment is awesome

hello greate video can you make one configuring with helm making jetstreams with helm infact using helm to do clusters and everything

[@h_yeomans]

Thank you for all the videos, I would some more practical/tutorial based videos.

[@rafaelgaia8677]

great content!! Thank you!

[@SynadiaCommunications]

Glad you liked it!

[@ds-ns1jj]

Does nats python also support Micro?

[@SynadiaCommunications]

Not yet, but we do want to support it

[@adriankardasz3126]

@@SynadiaCommunications Is there a roadmap document or something for the nats-py lib? This seems like an extremely useful feature and would love to see status updates for it.

super cool way to handle microservices

Totally!
