Settings View Source mix phx.new (Phoenix v1.7.0-rc.3)

Creates a new Phoenix project.

It expects the path of the project as an argument.

$ mix phx.new PATH [--module MODULE] [--app APP]

A project at the given PATH will be created. The application name and module name will be retrieved from the path, unless --module or --app is given.

options

Options

• --umbrella - generate an umbrella project, with one application for your domain, and a second application for the web interface.

• --app - the name of the OTP application

• --module - the name of the base module in the generated skeleton

• --database - specify the database adapter for Ecto. One of:

  • postgres - via https://github.com/elixir-ecto/postgrex
  • mysql - via https://github.com/elixir-ecto/myxql
  • mssql - via https://github.com/livehelpnow/tds
  • sqlite3 - via https://github.com/elixir-sqlite/ecto_sqlite3

  Please check the driver docs for more information and requirements. Defaults to "postgres".

• --no-assets - do not generate the assets folder. When choosing this option, you will need to manually handle JavaScript/CSS if building HTML apps

• --no-ecto - do not generate Ecto files

• --no-html - do not generate HTML views

• --no-gettext - do not generate gettext files

• --no-dashboard - do not include Phoenix.LiveDashboard

• --no-live - comment out LiveView socket setup in assets/js/app.js. Automatically disabled if --no-html is given

• --no-mailer - do not generate Swoosh mailer files

• --binary-id - use binary_id as primary key type in Ecto schemas

• --verbose - use verbose output

• -v, --version - prints the Phoenix installer version

When passing the --no-ecto flag, Phoenix generators such as phx.gen.html, phx.gen.json, phx.gen.live, and phx.gen.context may no longer work as expected as they generate context files that rely on Ecto for the database access. In those cases, you can pass the --no-context flag to generate most of the HTML and JSON files but skip the context, allowing you to fill in the blanks as desired.

Similarly, if --no-html is given, the files generated by phx.gen.html will no longer work, as important HTML components will be missing.

installation

Installation

mix phx.new by default prompts you to fetch and install your dependencies. You can enable this behaviour by passing the --install flag or disable it with the --no-install flag.

examples

Examples

$ mix phx.new hello_world

Is equivalent to:

$ mix phx.new hello_world --module HelloWorld

Or without the HTML and JS bits (useful for APIs):

$ mix phx.new ~/Workspace/hello_world --no-html --no-assets

As an umbrella:

$ mix phx.new hello --umbrella

Would generate the following directory structure and modules:

hello_umbrella/   Hello.Umbrella
  apps/
    hello/        Hello
    hello_web/    HelloWeb
