Lamg.Env

F# library for environment/secret loading, result / taskResult computation expressions, and generic SQLite transaction helpers.

Install

dotnet add package Lamg.Env

Modules

Module Purpose
Lamg.Env.Result result and taskResult computation expressions
Lamg.Env.Secrets dotenv.net load + 1Password CLI (op)
Lamg.Env.Console Colored console helpers
Lamg.Env.Env Env vars (getEnv, requireEnv, …) + small time helpers
Lamg.Env.Sqlite Generic dbTxn / nested CE for SQLProvider (or any) contexts

Secrets

open Lamg.Env.Result
open Lamg.Env.Secrets

loadDotEnv ()

// Prefer local env; fall back to 1Password (same names as field labels)
let! secrets =
  resolveFromEnvOrOnePassword [ "API_KEY"; "API_SECRET" ] "my-vault" "my-item"

// Or always load from 1Password and map fields yourself
let! json = getItem "my-vault" "my-item" (Some [ "API_KEY" ])
let! fields = fieldsByLabel json
let apiKey = fields["API_KEY"]

Set OP_SERVICE_ACCOUNT_TOKEN (e.g. in .env) or use an interactive op signin session.

Computation expressions

open Lamg.Env.Result

let work = taskResult {
  let! a = Ok 1
  let! b = someAsyncWork ()
  return a + b
}

SQLite / SQLProvider transactions (Lamg.Env.Sqlite)

No SQLProvider or SQLite package dependency — supply a DbSession<'ctx> that knows how to open and commit your app context:

open Lamg.Env.Sqlite

// Example with a SQLProvider-generated DataContext:
let session: DbSession<MyDb.dataContext> =
  { connect = fun path -> MyDb.GetDataContext($"Data Source={path};Foreign Keys=True")
    submitUpdates = fun ctx -> ctx.SubmitUpdates() }

let db = dbTxn session "app.db"
let readDb = readOnlyDbTxn session "app.db"

let! rows = db.Run(fun ctx ->
  // stage writes on ctx; outermost successful write Run calls submitUpdates
  ...)

Semantics:

  • Nested Run on the same DB path reuses the active context when modes allow
  • Read-only may nest under write; write under read-only → DbError.ReadWriteInsideReadOnly
  • Outermost successful read-write run calls submitUpdates
  • Per-path write gate serializes outermost write transactions

Develop

dotnet build Lamg.Env.slnx
