HTML Injector 
Browsersync plugin for injecting HTML changes without reloading the browser. Requires an existing page with a <body> tag.
Install (Node V4.0.0 & above)
$ npm i browser-sync bs-html-injector
Install (Node V0.10.x 0.12.x)
$ npm i browser-sync bs-html-injector@2
Examples & Recipes including html-injection
Options
files - String, Array
File watching patterns that will trigger the injection. NOTE: Ensure you are
not also watching the same file through the regular Browsersync
config - this will cause a full reload and the inject will not happen
browserSync.use(require("bs-html-injector"), {
files: ["app/*.html", "app/templates/**"]
});
restrictions - Array
Limit the comparisons to a certain elements.
browserSync.use(require("bs-html-injector"), {
files: "app/*.html",
restrictions: ['#header', '#footer']
});
excludedTags - Array
When working from scratch within the body tag, the plugin will work just fine. But when you start
working with nested elements, you might want to add the following configuration to improve the
injecting.
browserSync.use(require("bs-html-injector"), {
files: "app/*.html",
excludedTags: ["BODY"]
});
Example
Create a file called bs.js and enter the following: (update the paths to match yours)
// requires version 2.0 of Browsersync or higher.
var browserSync = require("browser-sync").create();
var htmlInjector = require("bs-html-injector");
// register the plugin
browserSync.use(htmlInjector, {
// Files to watch that will trigger the injection
files: "app/*.html"
});
// now run Browsersync, watching CSS files as normal
browserSync.init({
files: "app/styles/*.css"
});
Gulp example
var gulp = require("gulp");
var browserSync = require("browser-sync").create();
var htmlInjector = require("bs-html-injector");
/**
* Start Browsersync
*/
gulp.task("browser-sync", function () {
browserSync.use(htmlInjector, {
files: "app/*.html"
});
browserSync.init({
server: "test/fixtures"
});
});
/**
* Default task
*/
gulp.task("default", ["browser-sync"], function () {
gulp.watch("test/fixtures/*.html", htmlInjector);
});
Grunt example
// This shows a full config file!
module.exports = function (grunt) {
grunt.initConfig({
watch: {
files: 'app/scss/**/*.scss',
tasks: ['bsReload:css']
},
sass: {
dev: {
files: {
'app/css/main.css': 'app/scss/main.scss'
}
}
},
browserSync: {
dev: {
options: {
watchTask: true,
server: './app',
plugins: [
{
module: "bs-html-injector",
options: {
files: "./app/*.html"
}
}
]
}
}
},
bsReload: {
css: "main.css"
}
});
// load npm tasks
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-browser-sync');
// define default task
grunt.registerTask('default', ['browserSync', 'watch']);
};
