Swagger Merge and PDF Generator

A re-frame application designed to merge multi swagger json file and generate pdf by rapiPdf, support simple and traditional chinese!

Getting Started

Project Overview

• Architecture: Single Page Application (SPA)
• Languages
  • Front end is ClojureScript with (re-frame)
• Dependencies
  • UI framework: re-frame (docs, FAQs) -> Reagent -> React
  • Client-side routing: bidi and pushy
• Build tools
  • CLJS compilation, dependency management, REPL, & hot reload: shadow-cljs
• Development tools
  • Debugging: CLJS DevTools, re-frisk

Directory structure

• /: project config files
• dev/: source files compiled only with the dev profile
  • user.cljs: symbols for use during development in the ClojureScript REPL
• resources/public/: SPA root directory; dev / prod profile depends on the most recent build
  • index.html: SPA home page
    • Dynamic SPA content rendered in the following div:

      <div id="app"></div>

    • Customizable; add headers, footers, links to other scripts and styles, etc.
  • Generated directories and files
    • Created on build with either the dev or prod profile
    • js/compiled/: compiled CLJS (shadow-cljs)
      • Not tracked in source control; see .gitignore
• src/demo/: SPA source files (ClojureScript, re-frame)
  • core.cljs: contains the SPA entry point, init
• .github/workflows/: contains the github actions pipelines.
  • test.yaml: Pipeline for testing.

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. Clone this repo and open a terminal in the demo 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, browser test runner and karma test runner with hot reload:

npm install
npx shadow-cljs watch app

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

Debug Logging

The debug? variable in config.cljs defaults to true in dev builds, and false in prod builds.

Use debug? for logging or other tasks that should run only on dev builds:

(ns demo.example
  (:require [demo.config :as config])

(when config/debug?
  (println "This message will appear in the browser console only on dev builds."))

Production

Build the app with the prod profile:

npm install
npm run release

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.
