Genie.jl

🧞 The highly productive Julia web framework

Docs current status Website Tests Genie Downloads Tweet

Built with ❤︎ by contributors

Genie.jl is the backbone of the Genie Framework, which provides a streamlined and efficient workflow for developing modern web applications. It builds on Julia's strengths (high-level, high-performance, dynamic, JIT compiled), exposing a rich API and a powerful toolset for productive web development.

Genie Framework is composed of four main components:

  • Genie.jl: the server backend, providing features for routing, templating, authentication, and much more.
  • Stipple.jl: a package for building reactive UIs with a simple and powerful low-code API in pure Julia.
  • Genie Builder: a VSCode plugin for building UIs visually in a drag-and-drop editor.
  • SearchLight.jl: a complete ORM solution, enabling easy database integration without writing SQL queries.

To learn more about Genie, visit the documentation, and the app gallery.

🔌 WebSocket: Genie provides a powerful workflow for client-server communication over websockets

julia> using Genie, Genie.Router

julia> channel("/foo/bar") do
         # process request
       end
[WS] /foo/bar => #1 | :foo_bar

📃 Templating: Built-in templates support for HTML, JSON, Markdown, JavaScript views.

🔐 Authentication: Easy to add database backed authentication for restricted area of a website.

julia> using Pkg

julia> Pkg.add("GenieAuthentication") # adding authentication plugin

julia> using GenieAuthentication

julia> GenieAuthentication.install(@__DIR__)

Tasks: Tasks allow you to perform various operations and hook them with crons jobs for automation

module S3DBTask
# ... hidden code

  """
  Downloads S3 files to local disk.
  Populate the database from CSV file
  """
  function runtask()
    mktempdir() do directory
      @info "Path of directory" directory
      # download record file
      download(RECORD_URL)

      # unzip file
      unzip(directory)

      # dump to database
      dbdump(directory)
    end
  end

🗃️ ORM Support: Explore SearchLight a complete ORM solution for Genie, supporting Postgres, MySQL, SQLite and other adapters

function search(user_names, regions, startdate, enddate)
# ... hidden code

  where_filters = SQLWhereEntity[
      SQLWhereExpression("lower(user_name) IN ( $(repeat("?,", length(user_names))[1:end-1] ) )", user_names),
      SQLWhereExpression("date >= ? AND date <= ?", startdate, enddate)
  ]

  SearchLight.find(UserRecord, where_filters, order=["record.date"])

  • Database Migrations
module CreateTableRecord

import SearchLight.Migrations: create_table, column, primary_key, add_index, drop_table

function up()
  create_table(:record) do
    [
      primary_key()
      column(:user_uuid, :string, limit = 100)
      column(:user_name, :string, limit = 100)
      column(:status, :integer, limit = 4)
      column(:region, :string, limit = 20)
      column(:date_of_birth, :string, limit = 100)
    ]
  end

  add_index(:record, :user_uuid)
  add_index(:record, :user_name)
