Quick Start

Translations are exposed using the Trans.<domain> module like following:

import Trans.Messages as Messages
import Trans.Security as Security

displayStuff : Html msg
displayStuff =
    div [] [ text Messages.alert_awesome_plugin ]
    div [] [ text Security.global_must_have ]

The routing is exposed using the Routing module like following:

import Http
import Routing

makeHttpCall : Cmd msg
makeHttpCall =
    Http.get
        { url = Routing.app_get_this_plugin
        , expect = Http.expectString MsgGetThisPlugin
        }

Installation

You can install the webpack plugin with npm or with yarn:

# NPM
npm install elm-symfony-bridge --save-dev

# Yarn
yarn add elm-symfony-bridge --dev

And you're all done!

Configuration

Add the loader before elm-webpack-loader in your webpack configuration :

    {
        test: /\.elm$/,
        exclude: [/elm-stuff/, /node_modules/],
        use: [
            {
                loader: 'elm-symfony-bridge',
                options: {
                    dev: !Encore.isProduction(),    // Required: use symfony's env=dev or env=prod
                    outputFolder: './elm-stuff/generated-code/elm-symfony-bridge'
                                                    // Optional: set the folder where to put intermediate build artifacts, defaults to './elm-stuff/generated-code/elm-symfony-bridge'
                    projectRoot: './',              // Optional: root folder of your symfony project, defaults to './'
                    elmRoot: './assets/elm',        // Optional: root folder of your elm code, defaults to './assets/elm'
                    elmVersion: '0.19',             // Optional: elm version the generated code should be compatible with, defaults to '0.19', available '0.19' and '0.18'

                    enableRouting: true,            // Optional: enable generating routes, defaults to true
                    urlPrefix: '/index.php',        // Optional: when dev is true, which prefix to use when generating urls, defaults to '/index.php' (symfony >= 4 uses '/index.php', symfony < 4 '/app_dev.php')

                    enableTranslations: true,       // Optional: enable generating translations, defaults to true
                    lang: 'en',                     // Optional: lang to use when exporting translations, defaults to 'en'

                    envVariables: {                 // Optional: variables to replace during compile time, will also read env vars
                        '%variable%': 'ENV_VAR'
                    },
                }
            },
            {
                loader: 'elm-webpack-loader',
                options: {
                    pathToElm: 'node_modules/.bin/elm',
                    debug: !Encore.isProduction(),
                    optimize: Encore.isProduction()
                }
            }
        ]
    })
