av-gulp-injector
A nodeJs / gulp module in complement of gulp-asset to automatically import assets to your files
Pre-requesite
This node.js modules provide a function design to be implemented into a gulp.js task, please refer on the doc to learn more about gulp.
Download
You can download the node package via npm
npm install --save-dev av-gulp-injectorUsage
Av-gulp-injector embeds gulp inject , limit its usage to the AppVentus Workflow's needs (oriented Symfony) and add features like json imports and path aliases.
Basics
Av-gulp-injector will look for JSON files named injector.json all over your
architecture. The content of thoses files must be on this model :
{
"tag": [
"path/to/an/asset.js",
"path/to/an/asset.css",
],
...
}Running the gulp task below will make av-gulp-injector looking for all the
injector.json files and import the dependencies listed into the gulp.src
object parameter of the avInjector.injector() method.
var gulp = require('gulp');
var avInjector = require('av-gulp-injector');
gulp.task('injector', function() {
avInjector.injector(gulp.src('index.html'));
});The importation works with tag, that means that the template which will receive the assets to inject has to have comments to show where to import assets. (Please refer to the gulp inject doc for more details).
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Acme</title>
<!-- tag:css -->
<!-- endinject -->
<!-- tag:js -->
<!-- endinject -->
</head>
<body></body>
</html>Aliases
Into your injector.json you can use aliases that will avoid you to specify
a part of the path. During the importation the alias will be replace by the real
path partial.
It can be usefull if you develop a component that can be available with bower or
npm and you don't know where the location of the bower_components or
node_modules folders.
For example I have a injector.json file like this one :
{
"head": [
"@bower/my-component/style.css",
],
}If you want to inject the style.css referenced with a @bower alias, you have
to create an javascript object that will be passed as second argument of the
method avInjector.injector() as shown below;
var gulp = require('gulp');
var avInjector = require('av-gulp-injector');
var injectorAliases = {
'@bower': 'bower_components',
}
gulp.task('injector', function() {
avInjector.injector(gulp.src('index.html'), injectorAliases);
});The task injector will import the file at the path
bower_components/my-component/style.css
File import
As this workflow is made for Symfony2 the import of css and html files will be
with a path wrapped by the function asset(), and paths that starts with web/
will be cut off the web folder reference.
Av-gulp-injector supports injection into .html.twig & scss files.
You can pass a third argument into the avInjector.injector() method that is a
boolean for setting the path injections in relative way. By default, this
argument is false.
