Ecto SQLite3 Adapter

Build Status Hex Package Hex Docs

An Ecto SQLite3 Adapter. Uses Exqliteas the driver to communicate with sqlite3.

Caveats and limitations

See Limitationsin Hexdocs.

Installation

defp deps do [ {:ecto_sqlite3, "~> 0.17"} ] end

Usage

Define your repo similar to this.

defmodule MyApp.Repo do use Ecto.Repo, otp_app: :my_app, adapter: Ecto.Adapters.SQLite3 end

Configure your repository similar to the following. If you want to know more about the possible options to pass the repository, checkout the documentation for Ecto.Adapters.SQLite. It will have more information on what is configurable.

config :my_app, ecto_repos: [MyApp.Repo]

config :my_app, MyApp.Repo, database: "path/to/my/database.db"

Database Encryption

As of version 0.9, exqlite supports loading database engines at runtime rather than compiling sqlite3.c itself. This can be used to support database level encryption via alternate engines such as SQLCipheror the Official SEE extension. Once you have either of those projects installed on your system, use the following environment variables during compilation:

tell exqlite that we wish to use some other sqlite installation. this will prevent sqlite3.c and friends from compiling

export EXQLITE_USE_SYSTEM=1

Tell exqlite where to find the sqlite3.h file

export EXQLITE_SYSTEM_CFLAGS=-I/usr/local/include/sqlcipher

tell exqlite which sqlite implementation to use

export EXQLITE_SYSTEM_LDFLAGS=-L/usr/local/lib -lsqlcipher

Once you have exqlite configured, you can use the :key option in the database config to enable encryption:

config :my_app, MyApp.Repo, database: "path/to/my/encrypted-database.db", key: "supersecret'

Benchmarks

We have some benchmarks comparing it against the MySQL and Postgres adapters.

You can read more about those at bench/README.md.
