| Technical overview | A description of Mastodon's architecture. |
|
Mastodon is a Ruby on Rails application with a React.js front-end. It follows standard practices of those frameworks, so if you are already familiar with Rails or React.js, you will not find any surprises here.
The best way of working with Mastodon in a development environment is installing all the dependencies on your system, rather than using Docker or Vagrant. You need Ruby, Node.js, PostgreSQL and Redis, which is a pretty standard set of dependencies for Rails applications.
Tutorials for installing these dependencies can be found on the “Installing from source” page in the Running Mastodon section of the documentation. Please keep in mind that root access to a machine running Ubuntu 18.04 is required. After following the installation guide in the Running Mastodon section, see the “Setting up a dev environment” page for further instruction on how to configure your environment for development.
Environments
An “environment” is a set of configuration values intended for a specific use case. Some environments could be: development, in which you intend to change the code; test, in which you intend to run the automated test suite; staging, which is meant to preview the code to end-users; and production, which is intended to face end-users. Mastodon comes with configurations for development, test and production.
The default value of RAILS_ENV is development, so you don’t need to set anything extra to run Mastodon in development mode. In fact, all of Mastodon’s configuration has correct defaults for the development environment, so you do not need an .env file unless you need to customize something. Here are some of the different behaviours between the development environment and the production environment:
- Ruby code reloads itself when you change it, which means you don’t need to restart the Rails server process to see changes
- All errors you encounter show stack traces in the browser, rather than being hidden behind a generic error page
- Webpack runs continuously and re-compiles JS and CSS assets when you change any of the front-end files, and the pages automatically reload
- Caching is disabled by default
- An admin account with the e-mail
admin@localhost:3000and passwordmastodonadminis created automatically duringdb:seed
It should be noted that the Docker configuration distributed with Mastodon is optimized for the production environment, and so is an extremely bad fit for development. The Vagrant configuration, on the other hand, is meant specifically for development and not production use.
