This is the code for a workshop at RailsConf 2021, see the other workshops on the program at https://railsconf.com/program/workshops.
Last December, the team behind Basecamp and Hey released Hotwire, a library for managing client side interactions by sending HTML to the client. Hotwire bundles the Stimulus JavaScript library with an expanded Turbo library which makes a wide range of client side interactions possible without writing any custom JavaScript. In this workshop, attendees will see first-hand how powerful the new library is by adding powerful interactions to a basic Rails view.
This workshop assumes you already know a little bit about Ruby, Rails and JavaScript, but doesn't require expert level knowledge of any of those things.
The workshop uses this Rails application as an example. I recommend that you download it and get it working before the workshop starts.
Questions about the workshop or about setup should be directed to Noel at mailto:[email protected].
In order to run this application you'll need:
- Ruby 3.0 (If you don't have Ruby 3.0, change the
.ruby-versionfile, and the version of Ruby in theGemfile, Ruby 2.7.x should work. Ruby 2.6.x apparently does not work.) - Yarn 1.x https://yarnpkg.com/getting-started/install, apparently,
yarn set version 1.22.5will work, and Yarn 2.0 will still not work with Webpacker. - Whatever version of Node lets you run Yarn. https://nodejs.org/en/
- Sqlite3 (I think any recent version will work) https://www.sqlite.org/download.html or
brew install sqlite3
After downloading the app:
- run
bin/setup-- this will download gems and JavaScript packages.
The database is already pointing to binary Sqlite3 files in db, so you
can run the app with rails server, then see the result at
http://localhost:3000.
