elastic VS Buffalo

i am trying to generate the following query using github.com/olivere/elastic/v7

I think that https://olivere.github.io/elastic/ is a lot better as an API client

For Go available two good libraries for elasticsearch, the official Elasticsearch client and another one from community olivere elastic, both is good, but at this moment only the official client supports 8 version of elasticsearch and for serious production think it's the choice.

You are using the Query DSL, which is documented here, and has examples for boolean combination queries, so if you want it built up in a more strongly-typed fashion, check the documentation for it: https://github.com/olivere/elastic/wiki/QueryDSL

ElasticSearch repository implementation uses go-elasticsearch official library, another good one is olivere elastic but here it's not support 8 version which used for this project.

In this project we have microservice working with EventStoreDB using oficial go client, for [projections (https://zimarev.com/blog/event-sourcing/projections/) used MongoDB and Elasticsearch for search, and communicate by gRPC and REST. Did not implement here any interesting business logic and didn't cover tests, because don't have enough time, the events list is very simple: create a new order, update shopping cart, pay, submit, cancel, change the delivery address, complete order, and of course in real-world better use more concrete and meaningfully events, but the target here is to show the idea and how it works. Event Sourcing can be implemented in different ways, used here EventStoreDB, but we can do it with PostgreSQL and Kafka for example. After trying both approaches, found EventStoreDB is a better solution because all required features are implemented out of the box, it is optimized and really very good engineers developing it.

Relevant Discussion from the maintainer

I have only used the olivere library and I think it is as good as a Go library gets.

You should probably stop because this is not a Go-way. And you wan't find anything with "batteries" other than https://github.com/gobuffalo/buffalo and https://github.com/beego/beego

Haven't see anyone actually using them in production though.

No default. There is Buffalo which is modeled after Rails, haven't used it in anger though.

https://gobuffalo.io

In general, no. But if you do seek for one, I think https://gobuffalo.io is very good.

There is https://gobuffalo.io/ and there is https://github.com/livebud/bud. Both are interesting approaches, but sadly, without real business interest from the community. See, 90% of what makes Laravel Laravel (or Rails Rails) is business adoption. And, as you will sadly find out, the business adoption for traditional Web applications is exactly zero. If you don't want to make the same mistake as I did, and spend 3 years of your life searching for it, do as the others advised - just use the tools and frameworks that have already been built to solve the problem you need.

If you like Ruby on Rails, there is Buffalo.

Buffalo is currently built on Gorilla which complicates building a business on it right now as Gorilla has shifted to public archive since it has no maintainer. https://github.com/gobuffalo/buffalo/issues/2360
