Let’s pay attention to the first option, -live. -binary-id - use binary_id as primary key type in Ecto schemas.-no-dashboard - do not include Phoenix.LiveDashboard.-no-gettext - do not generate gettext files.-no-html - do not generate HTML views.-no-ecto - do not generate Ecto files.When choosing this option, you will need to manually handle JavaScript dependencies if building HTML apps -no-webpack - do not generate webpack files for static asset building.mssql - via Please check the driver docs for more information and requirements.-database - specify the database adapter for Ecto.-module - the name of the base module in the generated skeleton.-app - the name of the OTP application.-umbrella - generate an umbrella project, with one application for your domain and a second application for the web interface.-live - include Phoenix.LiveView to make it easier than ever to build interactive, real-time applications.Let’s take a look by running the following command: But before you dive in, it’s crucial that you understand the options available when making a Phoenix project. Running mix phx.new from any directory will create a new Phoenix application. Mix phx # Prints Phoenix help information mix phx.digest # Digests and compresses static files mix # Removes old versions of static assets mix # Generates a self-signed certificate for HTTPS testing mix # Generates a Phoenix channel mix # Generates a context with functions around an Ecto schema mix # Generates an embedded Ecto schema file mix # Generates controller, views, and context for an HTML resource mix # Generates controller, views, and context for a JSON resource mix # Generates LiveView, templates, and context for a resource mix # Generates a Presence tracker mix # Generates an Ecto schema and migration file mix # Generates a secret mix phx.new # Creates a new Phoenix v1.5.4 application mix # Creates a new Ecto project within an umbrella project mix # Creates a new Phoenix web project within an umbrella project mix phx.routes # Prints all routes mix phx.server # Starts applications and their servers Create a folder to persist the DB data.For this tutorial, you can leverage Docker and get a local version running by taking the following steps: Postgres can be a little tricky to install depending on the operating system you’re using. You can easily install Node.js from their official instructions, but in most cases, it’s possible your system might already have Node preinstalled. Additionally, you will need to have npm installed locally and a running version of PostgreSQL. I would recommend focusing on the local install for this tutorial, as it might be the easiest one to get started. Local installation on Linux, Windows, and macOS.The easiest way to do this is to follow the official Elixir instructions, which will give you a couple of options for: Here’s a sample of how the final application will work: The Crowdfunding App Pre-Build Setupįor this tutorial, make sure you have a good working Elixir environment. How to implement real-time updates on your application.How Phoenix leverages WebSockets for communication.The goal of this application is not to build a fully-featured crowdfunding platform but to get your feet wet with LiveView: Our application will allow users to support a funding goal in real-time and see the funding goal update as other users also commit to a specific amount. Explaining Today’s Tutorialįor this tutorial, we are going to be building a crowdfunding application that will leverage the real-time capabilities of Phoenix LiveView. This allows you to implement real-time functionality on your applications with ease. Phoenix LiveView adds bi-directional communication via WebSockets between the server and the client, without needing dedicated JavaScript code on the frontend. Developers can build rich, real-time user experience with purely server-rendered HTML. Phoenix LiveView is a relatively new library added to the Phoenix stack. Additionally, Phoenix also has the capability to build highly responsive real-time applications. If you’re currently working with a web framework like Ruby on Rails or even Laravel, you should definitely give Phoenix some attention due to the performance gains it promises. Phoenix offers productivity levels comparable to frameworks like Ruby on Rails while being one of the fastest web frameworks available. The Elixir language, along with the Phoenix framework, has been growing in popularity at a quick pace, and with good reason.
