HTML Injector Build Status

Browsersync plugin for injecting HTML changes without reloading the browser. Requires an existing page with a <body> tag.

$ 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']);
};
