+[`.gitignore`](.gitignore))

+* [`dev/`](dev/): source files compiled only with the [dev](#running-the-app) profile

+  - [`user.cljs`](dev/cljs/user.cljs): symbols for use during development in the

+[ClojureScript REPL](#connecting-to-the-browser-repl-from-a-terminal)

+* [`resources/public/`](resources/public/): SPA root directory;

+[dev](#running-the-app) / [prod](#production) profile depends on the most recent build

+  - [`index.html`](resources/public/index.html): SPA home page

+    - Dynamic SPA content rendered in the following `div`:

+        ```html

+  - [`test.yaml`](.github/workflows/test.yaml): Pipeline for testing.

+

+

+### Editor/IDE

+

+Use your preferred editor or IDE that supports Clojure/ClojureScript development. See

+[Clojure tools](https://clojure.org/community/resources#_clojure_tools) for some popular options.

+

+### Environment Setup

+

+1. Install [JDK 8 or later](https://openjdk.java.net/install/) (Java Development Kit)

+2. Install [Node.js](https://nodejs.org/) (JavaScript runtime environment) which should include

+   [NPM](https://docs.npmjs.com/cli/npm) or if your Node.js installation does not include NPM also install it.

+4. Install [clj-kondo](https://github.com/borkdude/clj-kondo/blob/master/doc/install.md) (linter)

+5. Clone this repo and open a terminal in the `dm` project root directory

+6. (Optional) Setup [lint cache](https://github.com/borkdude/clj-kondo#project-setup):

+    ```sh

+    clj-kondo --lint "$(npx shadow-cljs classpath)"

+    ```

+7. Setup

+[linting in your editor](https://github.com/borkdude/clj-kondo/blob/master/doc/editor-integration.md)

+

+### Browser Setup

+

+Browser caching should be disabled when developer tools are open to prevent interference with

+[`shadow-cljs`](https://github.com/thheller/shadow-cljs) hot reloading.

+

+Custom formatters must be enabled in the browser before

+[CLJS DevTools](https://github.com/binaryage/cljs-devtools) can display ClojureScript data in the

+console in a more readable way.

+

+#### Chrome/Chromium

+

+1. Open [DevTools](https://developers.google.com/web/tools/chrome-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](https://developer.mozilla.org/en-US/docs/Tools) (Linux/Windows: `F12` or

+`Ctrl-Shift-I`; macOS: `⌘-Option-I`)

+2. Open [Developer Tools Settings](https://developer.mozilla.org/en-US/docs/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](https://bugzilla.mozilla.org/show_bug.cgi?id=1262914).

+

+

+## 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:

+

+```sh

+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/](http://localhost:8280/).

+

+[`shadow-cljs`](https://github.com/thheller/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](https://code.thheller.com/blog/shadow-cljs/2019/08/25/hot-reload-in-clojurescript.html#things-to-avoid).

+

+Opening the app in your browser starts a

+[ClojureScript browser REPL](https://clojurescript.org/reference/repl#using-the-browser-as-an-evaluation-environment),

+to which you may now connect.

+

+#### Connecting to the browser REPL from Emacs with CIDER

+

+Connect to the browser REPL:

+```

+M-x cider-jack-in-cljs

+```

+

+See

+[Shadow CLJS User's Guide: Emacs/CIDER](https://shadow-cljs.github.io/docs/UsersGuide.html#cider)

+for more information. Note that the mentioned [`.dir-locals.el`](.dir-locals.el) file has already

+been created for you.

+

+#### Connecting to the browser REPL from VS Code with Calva

+

+See the [re-frame-template README](https://github.com/day8/re-frame-template) for [Calva](https://github.com/BetterThanTomorrow/calva) instuctions. See also https://calva.io for Calva documentation.

+

+

+#### Connecting to the browser REPL from other editors

+

+See

+[Shadow CLJS User's Guide: Editor Integration](https://shadow-cljs.github.io/docs/UsersGuide.html#_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`:

+    ```vim

+    :Piggieback :app

+    ```

+

+#### Connecting to the browser REPL from a terminal

+

+1. Connect to the `shadow-cljs` nREPL:

+    ```sh

+    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`:

+    ```clj

+    (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`](dev/cljs/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`](https://shadow-cljs.github.io/docs/UsersGuide.html#_command_line)

+actions:

+```sh

+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`):

+```sh

+npx shadow-cljs <action> app

+```

+### Debug Logging

+

+The `debug?` variable in [`config.cljs`](src/cljs/dm/config.cljs) defaults to `true` in

+[`dev`](#running-the-app) builds, and `false` in [`prod`](#production) builds.

+

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

+

+```clj

+(ns dm.example

+  (:require [dm.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:

+

+```sh

+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.
