Hoop Web App

This is the code for Hoop Web Application, designed to be a web portal for Hoop main users: DevOps and Software Developers.

Application powered by re-frame.

Getting Started

Project Overview

Editor/IDE

Use your preferred editor or IDE that supports Clojure/ClojureScript development. See Clojure tools for some popular options.

Environment Setup

  1. Install JDK 8 or later (Java Development Kit)
  2. Install Node.js (JavaScript runtime environment) which should include NPM or if your Node.js installation does not include NPM also install it.
  3. Install Chrome or Chromium version 59 or later (headless test environment) * For Chromium, set the CHROME_BIN environment variable in your shell to the command that launches Chromium. For example, in Ubuntu, add the following line to your .bashrc: bash export CHROME_BIN=chromium-browser
  4. Clone this repo and open a terminal in the webapp project root directory

Browser Setup

Browser caching should be disabled when developer tools are open to prevent interference with shadow-cljs hot reloading.

Custom formatters must be enabled in the browser before CLJS DevTools can display ClojureScript data in the console in a more readable way.

Chrome/Chromium

  1. Open DevTools (Linux/Windows: F12 or Ctrl-Shift-I; macOS: ⌘-Option-I)
  2. Open DevTools Settings (Linux/Windows: ? or F1; macOS: ? or Fn+F1)
  3. Select Preferences in the navigation menu on the left, if it is not already selected
  4. Under the Network heading, enable the Disable cache (while DevTools is open) option
  5. Under the Console heading, enable the Enable custom formatters option

Firefox

  1. Open Developer Tools (Linux/Windows: F12 or Ctrl-Shift-I; macOS: ⌘-Option-I)
  2. Open Developer Tools Settings (Linux/macOS/Windows: F1)
  3. Under the Advanced settings heading, enable the Disable HTTP Cache (when toolbox is open) option

Unfortunately, Firefox does not yet support custom formatters in their devtools. For updates, follow the enhancement request in their bug tracker: 1262914 - Add support for Custom Formatters in devtools.

Development

Running the App

Start a temporary local web server, build the app with the dev profile, and serve the app, tailwind css server, browser test runner and karma test runner with hot reload:

npm install

Running the Portal Web Hoop

Configuration

Copy and paste the .env.sample file to a .env file and replace the necessary values

cp .env.sample .env
``**

**Run it**

```sh
npm run dev

Please be patient; it may take over 20 seconds to see any output, and over 40 seconds to complete.

When [:app] Build completed appears in the output, browse to http://localhost:8280/.

shadow-cljs will automatically push ClojureScript code changes to your browser on save. To prevent a few common issues, see Hot Reload in ClojureScript: Things to avoid.

Opening the app in your browser starts a ClojureScript browser REPL, to which you may now connect.

Connecting to the browser REPL from your editor

See Shadow CLJS User's Guide: Editor Integration. Note that npm run watch runs npx shadow-cljs watch for you, and that this project's running build ids is app, browser-test, karma-test, or the keywords :app, :browser-test, :karma-test in a Clojure context.

Alternatively, search the web for info on connecting to a shadow-cljs ClojureScript browser REPL from your editor and configuration.

For example, in Vim / Neovim with fireplace.vim

  1. Open a .cljs file in the project to activate fireplace.vim
  2. In normal mode, execute the Piggieback command with this project's running build id, :app: 
    :Piggieback :app

Connecting to the browser REPL from a terminal

  1. Connect to the shadow-cljs nREPL:

    lein repl :connect localhost:8777

    The REPL prompt, shadow.user=>, indicates that is a Clojure REPL, not ClojureScript.

  2. In the REPL, switch the session to this project's running build id, :app:

    (shadow.cljs.devtools.api/nrepl-select :app)

    The REPL prompt changes to cljs.user=>, indicating that this is now a ClojureScript REPL.

  3. See user.cljs for symbols that are immediately accessible in the REPL without needing to require.

Running shadow-cljs Actions

See a list of shadow-cljs CLI actions:

npx shadow-cljs --help

Please be patient; it may take over 10 seconds to see any output. Also note that some actions shown may not actually be supported, outputting "Unknown action." when run.

Run a shadow-cljs action on this project's build id (without the colon, just app):

npx shadow-cljs <action> app

Make sure to bump the package.json version when making new Pull Requests running VERSION=x.x.x make bump-version

Production

Build the app with the prod profile:

npm install # install project dependencies
npm run release:hoop-ui

Please be patient; it may take over 15 seconds to see any output, and over 30 seconds to complete.

The resources/public/js/compiled directory is created, containing the compiled app.js and manifest.edn files.
