Prerequisites

• installed XAMPP or MAMP (apache server & php installation bundles)
• installed composer (php libraries)
• installed npm (deploy libraries)

Step 1: install Symfony installer

option 1 (recommended): download the installer, and move it to the directory where your repository should be located

php -r "readfile('https://symfony.com/installer');" > symfony
move symfony D:\Repos
php symfony new my_project

option 2: create the project with composer:

composer create-project symfony/framework-standard-edition my_project

follow the instructions in the console (you will probably need to configure your database & mail settings)

now, update all packages with composer:

composer update

Step 2: set up npm

create a file named package.json, adapt following json to your needs:

{
  "name": "my_project",
  "version": "0.1.0",
  "description": "My Project",
  "repository": {
    "type": "git",
    "url": "git://github.com/famoser/my_project.git"
  },
  "keywords": [
    "office",
	"online"
  ],
  "author": "Florian Moser <git@famoser.ch>",
  "license": "MIT",
  "bugs": {
    "url": "https://github.com/famoser/my_project/issues"
  },
  "homepage": "https://github.com/famoser/my_project",
  "devDependencies": {
    "bower": "^1",
    "browser-sync": "^2",
    "del": "^2",
    "gulp": "^3",
    "gulp-all": "^1",
    "gulp-batch": "^1",
    "gulp-bower": "^0",
    "gulp-clean-css": "^2",
    "gulp-concat": "^2",
    "gulp-less": "^3",
    "gulp-notify": "^2",
    "gulp-rename": "^1",
    "gulp-sass": "^2",
    "gulp-sourcemaps": "^1",
    "gulp-uglify": "^1",
    "gulp-watch": "^4",
    "less-plugin-autoprefix": "^1",
    "rimraf": "^2"
  }
}

run in your console

npm update

Step 3: set up bower

create a file named bower.json, adapt following json to your needs:

{
  "name": "my-project",
  "version": 0.1,
  "homepage": "https://github.com/famoser/my-project",
  "authors": [
    "famoser <git@famoser.ch>"
  ],
  "description": "My Project",
  "keywords": [
    "php"
  ],
  "license": "MIT",
  "ignore": [
    "**/.*",
    "node_modules",
    "bower_components",
    "test",
    "tests"
  ],
  "dependencies": {
    "jquery": "2.2.3",
    "bootstrap": "3.3.6",
    "components-font-awesome": "*"
  }
}

create a file named .bowerrc, with following json content:

{
    "directory": "web/assets/vendor/"
}

to create such a strange filename you can run

copy NUL > .bowerrc

in your console.

Step 4: set up build tools

I’ll use gulp for this.
Create a file named guldfile.js, content must be JavaScript. You’ll find a good starting point here: gist. There is quite a lot going on in this file, the instructions and the configuration is at the top.

Now run in your console

gulp

to build all frontend libraries for the first time.

Step 5: set up source control

• add a README.MD describing your project
• add a LICENSE.MD so other users may or may not be allowed to use your work (I’m recommending the MIT license)
• exclude unnecessary files from git (bower, composer & IDE files)

.idea
node_modules
/web/assets/vendor
symfony-scripts/.git

Step 6: rename your AppBundle

choose a custom name for your application, make it VendorApplicationBundle, so for example GoogleYoutubeBundle.
Files / Folder you need to adapt:

• The file /src/AppBundle/AppBundle.php
• The namespaces in all .php files inside /src/AppBundle/**/*.php
• The folder /src/AppBundle
• in /app/AppKernel.php you need to register your renamed bundle (just replace the old AppBundle/AppBundle entry)
