xo VS wire

i like xo's approach https://github.com/xo/xo but it is as is. I would love if something similar comes along that is used by db practititoners that is actively used and supported.

I use xo https://github.com/xo/xo . It generates CRUD queries by default so i don't have to write basic queries and it has option to write complex queries like sqlx. Only issue is it is not well documented.

SQL is an old, irregular language to work with, but it is better known than HCL and SQL already has it's own Pulumi/CDK in the form of every ORM with introspection (like Javascript's Prisma, Python's Django, Go's XO etc) and QueryBuilder (LINQ, Knex, etc) in whatever programming language you prefer. You probably already know it.

I am using the library xo to generate basic data retrieval code from a sql schema for a crud api.

Sorry for the confusion, we're not generating the database client itself, more like generating an ORM around a database client. The ORM takes these database clients as dependencies. It's very similar to the way XO works with it's multi-database support: https://github.com/xo/xo/tree/master/_examples/northwind

i use xo . Reason is i prefer designing schema first and creating golang scaffolding later. Xo takes schema and gives me basic create/update/delete operations by default and i can also generate gocode for any sql queries that i write.

Thanks for sharing your thoughts! I see that it works best with Postgresql. The other commenter mentioned https://github.com/xo/xo for MySql which might work well.

Thanks for your comment and question @onionisfruit. Top-notch handle too!

>> What are your plans for models and persistence?

I haven't worked out all the details, but it's going to be some blend of https://github.com/xo/xo and https://sqlc.dev/.

Design goals:

1. High-level, type-safe "ORM" that's generated from your database schema.

code generation is a mostly disjoint topic from DI. Granted, some solutions like https://github.com/google/wire use code generation, but you're exactly right about their pitfalls. If your dev environment doesn't have good support for generated code, it is a nightmare. If you can goto-definition the generated code, then it is suddenly feasible, but perhaps still a bad choice.

We use https://github.com/google/wire for every bigger project, take a look at it, it beautifully solves initialisation and also gives you a guideline on how to do it.

Im by no means a "purist" in such things, I love my magic and QoL-features/libs, but havent seen something that is so easy to use in go, that I immediately wanted to add it. And to be fair, I only looked closely at https://github.com/google/wire , others I have just skipped - and I will be looking into uber-fx as mentioned in the other comment.

If you have such a complex and deep dependency graph, and you don't want to manually maintain it, you could use some DI library to handle that for you. Something like https://github.com/google/wire for small-medium size stuff, or https://github.com/uber-go/fx for larger scale, more enterprise projects.

Try https://github.com/google/wire. Compile time generated like dagger 2 in java.

Most people probably do it by hand (I do). But otherwise, probably https://github.com/google/wire is the most popular, maybe followed by https://github.com/uber-go/fx.

For larger object graphs do you roll everything by hand or encourage something like https://github.com/google/wire

The other thing is that I'm lazy, so I don't construct all dependencies in main.go manually but use wire to generate the construction of my dependency tree.
