# GAS stack
|
|
|
|
## Concepts
|
|
|
|
- explict `schema.sql`
|
|
- solid-state applications
|
|
- no Docker
|
|
- https://git.tnd.gg/tnd/remichat/pulls/4#issuecomment-1218
|
|
- no environment split ("prod" vs "dev")
|
|
- environment distinctions are provided by scripts that call the application, not by the application
|
|
- try to avoid config files-- use shell scripts that pass flags instead
|
|
- put all the config variable values for a certain environment in that environment's runner context:
|
|
- values that are specific to Docker setups should go in docker-compose
|
|
- values that are for non-docker dev, maybe in .env or a runner shell script, or something like this
|
|
- assume that config values are finalized (i.e., don't need to be checked configVal == "" ? "default" : configVal) as high in the stack as possible (and also ensure this is the case). Ideally, vite.config.ts and onward already shouldn't need to do any val || "default" checking, and can simply accept env.PORT_NUMBER or env.IS_LOGGING_ENABLED as-is (or at most, parsing string->int, etc).

|
|
- no frontend-backend separation (CORS)
|
|
- minimal config
|
|
- avoid cascading configs and multiple layers of defaults (e.g., `{ XYZ: "prefix" + (upperlayer.XYZ || "DefaultValue"), ... }`)
|
|
|
|
- subcommands executables
|
|
- scriptable applications: anything that the application can do, can be done via command line (i.e., avoid web-only operations)
|
|
- config is passed as command-line args
|
|
- avoid config env-vars (magical)
|
|
- shell scripts as glue code

## SQLite and ROWID
|
|
|
|
Tables must be EITHER:
|
|
- `rowid integer primary key` as first column declaration; OR
|
|
- `without rowid`, i.e., a clustered index
|
|
|
|
Other primary key and rowid settings are supported by SQLite, but NOT by Gas Stack:
|
|
- implicit `rowid`
|
|
- alternate `integer primary key` column, i.e., rowid alias
|
|
- non-rowid `primary key` that isn't a clustered index (note that SQLite doesn't actually support this, it just pretends to; the declared `primary key` in this case is just a regular unique index)
|
|
|
|
This is enforced by the Gas Stack schema linter, and cannot be configured. Other Gas Stack schema tools assume one of these arrangements, and will not work right if it's not followed.
|
|
|
|
## What not to do
|
|
|
|
- "scripts" folder
|
|
- "bin" with shell scripts in it
|
|
- using HTTP PUT or PATCH
|
|
|
|

# Methodologies
|
|
|
|
- Timestamp type: store dates and times as int64 (unix millis)
|
|
- code tags: TODO, XXX, WTF, DUPE tags
|
|
- `go test -tags integration` for integration testing (slow tests)
|
|
- cobra commands
|
|
- sqlx
|
|
- :memory: databases for testing
|
|
- go-chi router
|
|
|
|
- No docker-compose
