storch

This package is superceded by the feather package, which offers a superset of storch’s functionality

gleam add storch

Add the following fields to your gleam.toml file:

# this can of course be anything you like
migrations_dir = "./priv/migrations"
schemafile = "./schema.sql"

Then run the command gleam run -m storch -- new "Initial schema migration" and make any changes you like.

Running the command gleam run -m storch -- schema will create the file ./schema.sql, (or whatever you set in your gleam.toml) with the schema of your database after all migrations have been applied.

import storch
import gleam/result
import gleam/erlang
import sqlight

pub fn main() {
  let assert Ok(priv_dir) = erlang.priv_directory("my_module_name")
  use migrations <- result.try(storch.get_migrations(priv_dir <> "/migrations"))
  use connection <- sqlight.with_connection(":memory:")
  storch.migrate(migrations, on: connection)
}
