Show HN: Roast my SQLite encryption at-rest
SQLite encryption at-rest is a hot requested feature of both the “default” CGo driver [1] and the transpiled alternative driver [2]. So, this is a feature I wanted to bring to my own Wasm based Go driver/bindings [3].
Open-source SQLite encryption extensions have had a troubled last few years. For whatever reason, in 2020 the (undocumented) feature that made it easy to offer page-level encryption was removed [4]. Some solutions are stuck with SQLite 3.31.1, but Ulrich Telle stepped up with a VFS approach [5].
Still, their solution seemed harder than something I'd want to maintain, as it requires understanding the structure of what's being written to disk at the VFS layer. So, I looked at full disk encryption for something with less of an impedance mismatch.
Specifically, I'm using the Adiantum tweakable and length-preserving encryption (with 4K blocks, matching the default SQLite page size), and encrypting whole files (rather than page content).
I'm not a cryptographer, so I'd really appreciate some roasting before release.
There is nothing very Go specific about this (apart from the implementation) so if there are no obvious flaws, it may make sense to port it to C/Rust/etc and make it a loadable extension.

Redis Re-Implemented with SQLite

Replacing Complicated Hashmaps with SQLite
SQLite is great. I've also recently settled on it as a key-value store, after considering a few purpose-built key-value solutions. Turns out that it's really easy to make SQLite work as a key-value store, but very difficult to make key-value stores relational.
Just be careful with `:memory:` databases. From the mattn/go-sqlite3 FAQ[1]:
> Each connection to ":memory:" opens a brand new in-memory sql database, so if the stdlib's sql engine happens to open another connection and you've only specified ":memory:", that connection will see a brand new database. A workaround is to use "file::memory:?cache=shared" (or "file:foobar?mode=memory&cache=shared"). Every connection to this string will point to the same in-memory database.
I noticed strange behaviors with just `:memory:` where tables would just disappear at random, and this workaround helped. Make sure to use a unique filename as the `file:` value, especially if using this in tests.

From Golang Beginner to Building Basic Web Server in 4 Days!
For building my web server, I chose to use the Gin framework as the foundation of my app. It was incredibly easy to understand and work with, and I was pleasantly surprised by how seamlessly it integrated with writing unit tests for the server. To handle the database, I leveraged the power of go-sqlite and migrate for efficient SQL queries and migrations. These libraries proved to be both powerful and user-friendly, making the development process a breeze.

Exciting SQLite Improvements Since 2020
SQLite does have an optional "user authentication" extension, though I've not personally tried it out:
https://www.sqlite.org/src/doc/trunk/ext/userauth/user-auth....
The widely used Go SQLite library by mattn says it supports it, if that's useful:

Go port of SQLite without CGo
I have an OSS project, sq which is a data-wrangling swiss-army knife for structured data. Think of it as jq for databases. It supports Postgres, SQLServer, MySQL and - relevantly - SQLite. It embeds SQLite via CGo and the mattn/go-sqlite3 driver.

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

JSON Canvas – An open file format for infinite canvas data
Check out https://github.com/zombiezen/go-sqlite if you're interested in trying out Sqlite in Go again. Nice interface, negligible compile time impact, fast, compiles without CGO. It's very comfortable.
I agree that going from text to sqlite is a bit of a hurdle, especially if you're not writing C :)

Jsonfile: A Quick Hack for Tinkering
struggling figuring out how to make my cgo sqlite cross-compile to Windows
Plenty of people trying to fix that.
There's at least:
https://modernc.org/sqlite
Then there's https://github.com/zombiezen/go-sqlite that actually builds https://crawshaw.io/sqlite on top of modernc.
And there's mine that has both a low level and a database/sql driver builds and runs everywhere Go does: https://github.com/ncruces/go-sqlite3

What’s your preferred setup to work with SQL DB (without ORM) ?
I like and use https://github.com/zombiezen/go-sqlite for CGo-free SQLite. It avoids some of the problems database/sql has, discussed here: https://crawshaw.io/blog/go-and-sqlite.

New advanced, CGo-free SQLite package
modernc.org/sqlite provides a database/sql driver, but does not (currently) provide an easy way to get at the more advanced functionality of SQLite, like streaming blob I/O or user-defined functions. David Crawshaw has argued that the database/sql API is not a good fit for SQLite, which is how crawshaw.io/sqlite came about.
